water-colded black mark水冷黑印
3)skid mark滑道黑印
1.The formation of billet steel rocker was calculated theoretically and analyzed using the differential method of rolling pressure along width in rolling deformation zone according to the position of the billet steel skid mark, the asymmetrical distribution of the mark degree and the departure of rolled piece centerline from the centerline of rolling.在轧制变形区应用轧制压力宽向微分法 ,从钢坯滑道黑印位置和黑印程度的非对称分布、轧件中心线偏离轧制中心线两方面对钢板镰刀弯的形成进行了理论计算和分析 ,提出了改进操作规程、提高推床适应能力、改进加热炉滑道、加强加热工艺技术管理以及实施热送热装提高热坯的供应能力等多项措施 ,以适应多倍尺轧制工艺的要求。
4)dark mark加热黑印
1.The blooms heated in pusher heating furnace generlly hav e serious dark mark and nicking which make the elongation property of steel pla te become worse and the scars and nicking be formedon the surface of steel pl ate.推钢式加热炉普遍存在着钢坯加热黑印较重,钢坯下表面被划伤造成钢板延伸性能不合格、钢板表面产生结疤、起皮等质量缺陷。
5)skid-mark钢坯黑印
1.The effects of skid structure,skid height and skid material on temperature distribution of billet and skid-mark temperature difference are studied.用数值模拟的方法研究了连续式加热炉内钢坯的加热过程,分析了滑轨结构、滑轨高度和滑轨材质等对钢坯黑印温差的影响,为消除钢坯黑印、提高钢坯加热质量提供了理论依据。
2.The effects of skid structure, skid height and skid material on temperature distribution and temperature difference of skid-mark are studied.用数值模拟的方法研究了推钢式加热炉内钢坯和热滑轨的加热过程,得到了滑轨结构、滑轨高度和滑轨材质等对钢坯黑印温差和出炉温度的影响,为消除钢坯黑印、提高钢坯加热质量提供了理论依据。
