Identifiering av slöserier på Lundbergs Plåt AB
Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of STEEL such as stainless STEEL. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.
Trä- och stålreglars påverkan av värmeflödet i utfackningsväggar
Inom dagens byggande i Sverige ställs allt högre krav på den värmeisolerande förmågan hos klimatskärmen i de hus som byggs. Detta ställer i sin tur högre krav på konstruktionerna och medför även ny problematik. Standardlösningar som tidigare fungerat bra byts ut mot nya, ibland obeprövade, lösningar. De hårdare kraven på energi- och fuktdimensionering innebär alltså att vikten av val av stommaterial ökar vid en projektering.Vi har här försökt ge en realistisk bild av hur valet av reglar kan påverka energi och fukttillståndet hos en byggnad med utfackningsväggar, med fokus på reglar i fält. Till undersökningen användes referensobjekt i form av ritningar som tillhandahölls av handledaren på Clarus arkitekter.
Arbetsmiljövänliga låsvätskor i stötdämpare
This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.
Hållbarhetsredovisning i stålbranschen : Att börja hållbarhetsredovisa med intressenternas behov i fokus
Background: Following an increased awareness concerning social and environmental aspectsin society, more enterprises establish sustainability reports in order to inform theirstakeholders about the company?s sustainability duties. A previous study indicates that themetal sector is enjoying relatively limited increases in business opportunities and/or financialvalue of corporate responsibility. Another study suggests that there is a gap in expectationsbetween producers and users of sustainability reports due to an uncertainty regarding whatinformation such reports should contain and what audience such reports should target. Thequestion is whether or not a gap in expectations concerning sustainability reporting is acontributing factor to the limited increases in financial value in the metal sector?Purpose: The purpose of the study was to examine how a sustainability report should becarried out by a company in the STEEL industry given what information the company and thestakeholders consider as essential in a sustainability report.Methodology: To accomplish the purpose of the study, a deductive approach was used due tothe availability of suitable theories.

Återvinning av industriell restvärme som värdeskapande process : En fallstudie på SSAB EMEA i Borlänge
The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the STEEL industry has reduced its energy consumption per ton of STEEL produced by 50 percent.
Allmänhetens inställning och riskperception gentemot stålverk : En enkätstudie
Stålindustrin förser såväl människor som samhället med många nödvändiga byggstenar. I Sverige finns tolv ståltillverkande anläggningar och hela 80 % av stålet exporteras. Som alla andra tillverkande industrier har den flera miljöaspekter att ta hänsyn till, men stålets nytta väger tungt och därför är det av stor vikt att genom forskningsprojektet Stålkretsloppet nå hållbar utveckling. Miljöskyddslagen, miljöbalken och ett ökande miljöengagemang har lett till arbete med miljöfrågor. Syftet med den här studien var att undersöka hur allmänhetens riskperception, attityd och oro gentemot stålindustrin ser ut.

Husproduktion, kritiska skeden i produktion
As a newly graduated student in construction you rarely have as much knowledge as you wish you had. It is a complicated line of business that requires knowledge and understanding of both technical solutions and interaction between actors. It is impossible to be fully learned and with that much unknown it can be hard to know where to start. This report is one step in the right direction. It contains a planning that contains construction and installations for a one level house in Kiruna with its different choices motivated.
Hårdfräsning i verktygsstål : Förslitning av skäregg
This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool STEELs: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool STEEL alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder STEEL with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

Analys och dimensionering av robusta kilspårsförband
This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.
