优质中高碳钢冷轧窄带钢生产

THE PRODUCTION OF HIGHQUALITY MEDIUMANDHIGHCARBON COLDROLLED NARROW STRIP STEEL

优质中、高碳钢的冷轧窄带坯料由于受其化学成分尤其是碳含量及热轧后冷却速度缓慢的影响，造成了内部组织的方向差异。通过合理的热处理制度和轧程安排。

Because of the influence of chemical composition, especially carbon content of semifinished product as well as the influence of low cooling rate after hot rolling, directional difference occurs in the internal structure of highquality mediumand highcarbon coldrolled narrow strip steelTherefore, in order to produce highquality cold rolled strip steel, we must use reasonable regulations of heat treatment and reasonable arrangement of rolling procedures
