Effect of Alkalis on Ironmaking Process in a Blast Furnace One of the main objectives during the operation of a blast furnace (BF) is to maximize the production of hot metal (HM) of the desired chemical composition at the minimum costs. This needs a high quality of a raw material base and a regular, smooth …
Read MoreLubrication and Lubricating Oils The principle of supporting a sliding load on a friction reducing film is known as lubrication. The substance of which the film is composed is a lubricant, and to apply it is to lubricate. All liquids provide lubrication of a sort, but some do it a great deal better than others. …
Read MoreEmployee Motivation and Organizational Performance An organization consists of a large or small group of individuals which is working under the direction of a management and a system for the accomplishment of certain common objectives. The individuals forming the group are the employees of the organization who contribute their efforts towards the achievement of the …
Read MoreSteel Cleanliness and Clean Steel Technologies Steel cleanliness is an important factor which decides the quality of the steel. It can have a remarkable influence on steel properties, such as tensile strength, formability, toughness, weldability, cracking-resistance, corrosion resistance, and fatigue-resistance etc. The demand for better mechanical properties of steels from the steel consumers has urged …
Read MoreStraightening Machines in Flat Rolling Mills Metal straightening or levelling process is used for straightening different type of steel materials like rounds, sections, pipes and flat products after their rolling. The rolled steel material gets deformed during cooling after rolling due to the residual stresses and often has the surface defects in cold condition such …
Read MoreEnergy Audit in Steel Plant Iron and steel plants have a large number of processes which involves different cycles such as heating, cooling, melting, and solidification. These processes are highly energy intensive. There are also several forms of energies which are being used in these plants. Further, these plants not only have high specific consumption …
Read MoreElectroslag Remelting Process Electroslag remelting (ESR) is the abbreviated name given to electroslag consumable electrode remelting and secondary refining process. It is a secondary steelmaking process which is used for remelting and refining of steels and special alloys normally used for critical applications in aircraft, thermal and nuclear power plants, and defence hardware, etc. The …
Read MoreHeat Treatment Processes for Steel Steels can be heat treated to produce a large range of microstructures and properties. Generally, heat treatment uses phase transformation during heating and cooling to change the microstructure in a solid state. In heat treatment, the processing is normally thermal and which modifies only the structure of the steel. In …
Read MoreHealth and Safety Practices and the Organizational Performance In a manufacturing organization, employees are exposed to hazards ranging from the use of chemicals, complex plant and equipment, working tools, heat and temperature, odour, noise, waste materials produced during operation, unguarded machinery, inadequate working space, and inadequate fire precautions etc. Also, employees are to work sometimes …
Read MoreProduction and Processing of Armour Steel In the present day environment, there are accelerated efforts to deliver lightweight armour technologies which can defeat armour-piercing (AP) projectiles at reduced areal weights. While many of these efforts involve the application of lower density metals such as aluminum and titanium, the selection of steel alloys continues to be …
