本文以生产实际为依据,简要介绍了在160mm小方坯连铸机设备上通过结晶器振动装置的改进,水环区增加小夹辊,以雾化喷嘴冷却二冷区,应用简易拉矫机压下调节装置,增设二冷区水流量自动控制和电磁搅拌等措施,加之在连铸工艺上铜水采用SL钢包喷粉,扩大中间包容量,应用注流保护浇注技术,合理控制注温、拉速和冷却水量的分布,以及适合的比水量相配合,将会获得质量良好的管坯。
In this paper, based on the actual production, a brief introduction to the 160mm billet caster equipment through the mold vibration device improvements, the water ring area to increase a small nip roller to cool the cooling zone with a spray nozzle, the application of simple straightening and leveler Pressure regulating device, an additional two cold zone water flow control and electromagnetic stirring and other measures, combined with the continuous casting process copper SL spray ladle to expand the tundish capacity, the application of flow pouring protection pouring technology, reasonable temperature control injection, Pulling speed and cooling water distribution, as well as the appropriate ratio of water, will get good quality tube.
