Critical analysis of a steel wire rod plant Processes for Energy Optimization-A case study
Energy is needed in the wire rod plant processes for any value addition activity to develop the finished product. The increased energy costs and an uncertain steel markets have created the demand for a system in the steel plant, to utilizes the rolling process waste heat, or improve rolling process so that next further processing may be avoided for rolled product.. The process energy optimization is a tool to improve profitability, environment and productivity of an organization. In a wire rod plant processes, the aim of energy saving can be achieved by reduced resource consumption and by efficient use of plant installation like reheating furnace, mills and utility. A case study is used to illustrate the rolling processes energy optimization and to demonstrate its applicability.
The effect of lubrication on mill loads during hot rolling of low carbon steel strips
Abstract Hot rolling experiments have been conducted, using low carbon steel strips. The effects of water, oil/water emulsions, neat oil and dry conditions at the roll/strip surface, on the resulting loads and temperatures were examined. The 1 : 1000 oil-to-water mix appeared to lower the mill loads the most. Doubling the oil volume was found to have a deleterious effect and did not create any further load reductions.
Formation and Strength of Magnesia Whiskers
The formation of single-crystal magnesia whiskers during the compressive deformation of single crystals at room temperatures is described. These whiskers can have strengths of the order of millions of pounds per square inch. They are formed during fracture as a result of the discontinuous propagation of cracks which are mechanically relieving internal stresses resulting from plastic flow
