| Abstract: | High-efficiency production organization should be simple and “laminar”. A one to one “laminar flow” operation mechanism is supposed to be accepted as a prerequisite to build high-efficiency clean steel “production platform”. Concerning the fact that establishing a one to one “laminar flow” production pattern is impossible at Tangshan Iron and Steel Co., Ltd., “quasi-laminar flow” production pattern was evaluated. Result shows that rolling bar products of various specifications have great impact on the liquid steel supply model between BOF and CC. Considering the process matching issue of steelmaking-continuous casting-rolling process in bar production line, a “quasi-laminar flow” production pattern between BOF and CC was proposed according to different rolling specification in bar mills. Through analysis and research on current production pattern, combined with principles and strategy for BOF workshop control, and taking the plant layout into account, “quasi-laminar flow” production pattern was finally established. Moreover, Gantt chart of “quasi-laminar flow” production pattern was drawn. It is shown that the relative “order degree” of the “quasi-laminar flow” production pattern rises, which is conductive to production scheduling and ladle operation turnaround in comparison with “turbulence” production pattern. While a careful evaluation should be conducted due to the fluctuant temperature drop caused by the inevitable inserted heats and decreased operation rate of inserted BOF before adapting the production pattern. |
