Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv
The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a Foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.
Materialhantering till och från robot
Material handling is a term that includes all kinds of handling of material from a raw product to a finished one. ABB is active in the following segments; Foundry, packaging and palletizing, metal industry and plastics industry.The demands for efficiency and reliability have been set very high in the industrial sector. Optimizing of the material handling will give the company higher cost-effectiveness. Around the robot there are different kinds of material flows, to optimize the cycle time, consisting of carriages combined in different ways.Motion Control is a complex system with main functions such as; positioning, synchronizing, indexing and more. The products in the system need to cooperate to make these functions possible therefore integration of motor- and servo products are important.
Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden
The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former Foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.

This thesis has been performed at International Aluminum Casting AB in Eskilstuna,Sweden.International Aluminum Casting is currently working with a number of improvementsin their production in order to achieve their vision of being the leading aluminum Foundry in Sweden. As a step in their improvement efforts, focus was directed ondeveloping the company's fixtures for machining.Efforts were focused on two main objectives: to develop a complete proposal on afixture which leads to a more rational use of an assigned part and also form general design advice for development of fixtures in the future.During the work progress, discussions have been made with experts at International Aluminum Casting within the field of fixture design. The objective was to obtain sufficient knowledge about the underlying problems with the current fixture for the part. At this stage of the thesis, a number of essential criteria for fixture design were produced. Information and inspiration were obtained by examining the company?s currently developed fixtures.After gathering the necessary information the process of developing three different fixture concepts started.
Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar
To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish Foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.
Tillståndsprövning - för lantbruk med djurhållning : en intervju undersökning med länsstyrelserna i Kalmar- och Hallands län.
The task of making a correct application for B- activities is the Foundry time consuming
task. Information and facts concerning your entire business activity shall be attached into
a description of environmental consequences, which will be the basis for the decision
making whether the activities shall be granted a permission to practise environmentally
hazardous actions or not.
When the Environmental Act were established 1999, the permission process became
more extensor. With this study I want to give an insight about how these applications are
made. The methods I have used to collect information are a study literature where the
Environmental Act has been the focus, and qualitative interviews with two County
Administrative Board. I used the Environmental Act to understand why permission is
needed and the interviews to give me insight in how the work is done.
My conclusion is that it is very unusual that an application is granted without
complements.
En studie om arbetsprocess under praktik : Samt en fördjupande undersökning om kritik
Under två månader, februari - april 2009, har jag haft praktikplats på ett produktionsbolag i Göteborg. Jag har gjort praktik samtidigt som jag har genomfört en etnografisk studie av medarbetarna på företaget. Arbetet har företrädesvis varit att skapa grafiskt material för reklamfilm. På min praktikplats har jag arbetat med grafiskt material. Jag har framför allt fått arbeta med programmet Maya (Autodesk Maya 2009) men också med andra programvaror som Nuke (The Foundry) och Photoshop (adobe). Arbetet har inneburit att arbeta med Maya och skapa 3D-objekt men även att göra saker som att rotoscopa i Nuke.
Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.
Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter
AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.

Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen
Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the Foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
