苏联亚速钢铁公司3600厚板轧机生产的钢板在直通辊底式热处理炉进行正火处理。为了提高正火处理效率,该公司试验成功利用轧制余热进行快速冷却使钢板性能达到正火状态的新工艺。采用这种新工艺生产的低合金钢板,与正火状态相比,强度、韧性和耐低温性能提高了10～205,在使用部门可节约钢材10%。另外,该公司采用这种新工艺后直通辊底式正
The steel plate produced by the 3600 heavy plate mill of the Soviet Union’s Speed Steel Company is normalized at the through-roller hearth heat treatment furnace. In order to improve the normalizing efficiency, the company tested a new process that successfully used the rolling residual heat for rapid cooling to achieve a normalized steel performance. The low-alloy steel plate produced by this new technology can improve the strength, toughness and low-temperature resistance by 10 ~ 205 compared with the normalized state, and can save 10% of the steel by using the department. In addition, the company adopted this new technology through the roller bottom positive
