双机架炉卷轧机16～20mm厚度规格热轧产品开发

Double Stand Steckel Mill 16 ~ 20 mm Thickness Specification Hot Rolled Product Development

昆钢板带厂结合双机架炉卷轧机设备、工艺特性，发掘设备和工艺潜能，采用未再结晶型控轧工艺和控制冷却工艺路线，突出强化未再结晶轧制工艺细晶效果，实现加热、终轧和卷取温度与设备能力的优化配合，开发出16—20mm厚Q235B和16mm厚Q345B热轧板卷产品，并实现稳定批量生产。

Kungang Strip Mill in combination with double stand steckel mill equipment, process equipment and process characteristics, explore potential, with process route of no recrystallization controlled rolling and controlled cooling process, highlighting the strengthening of no recrystallization rolling process for fine grain effect, realizing that the heating, the finish rolling and the optimization of coiling temperature and the ability of the equipment to cooperate, the 16 ~ 20mm thick Q235B and 16mm thick Q345B hot rolled products were developed, and to realize the stable mass production.
