- 摘要:
- 对中薄板坯连铸机板间漏钢的原因进行了分析。 结果表明，造成板间漏钢的主要原因是水口面氧化。 通过
优化水口面材质、提高水口面精度、改进水口烘烤工艺，确保上下水口对中、氩气压力在 0.01 MPa 以上，提高快换机构
液压缸速度、保证快换机构的精度和冷却效果，规范快换浸入式水口操作等措施，可以使中薄板坯连铸机无板间漏钢。
The reason of steel leakage between plate in medium-thin slab caster was analyzed. The results show that the main cause of steel leakage between plates is oxidation of nozzle surface. By optimizing the nozzle surface material, to improve the nozzle surface accuracy, to improve the slide baking process, to ensure that the gate on the up and down, argon gas pressure above 0.01 MPa, to improve the quick change institutions hydraulic cylinder speed and guarantee the accuracy of the quick change and cooling effect, fast in submerged nozzle measures such as operation, it can make in the thin slab continuous caster without plate between the steel.
