降低NM450耐磨钢板成本的方式有哪些?

1降低烧损
1. Reduce burning loss
实施冷热钢坯交替入炉。利用生产换辊时间提高钢坯温度保证凉坯的加热质量,同时减少热坯的加热时间,降低氧化烧损。对加热炉温度控制制度进行了优化。将145、183、204 系列小规格NM450耐磨钢的加热温度降低了20 ℃。
The hot and cold billets are fed into the furnace alternately. Using the roll changing time to improve the billet temperature, ensure the heating quality of the cold billet, reduce the heating time of the hot billet and reduce the oxidation burning loss. The temperature control system of heating furnace is optimized. The heating temperature of 145, 183, 204 series small size nm450 wear resistant steel is reduced by 20 ℃.
2降低切头
2. Reduce the cutting head
排料时将原料端部质量差的一端朝向尾部,对204 系列和233 系列进行选择性切头,其他系列均不再切头,以减少对头部的切损。对233、272系列的粗轧孔型优化,保证料型尺寸,降低了切损。在热剪处增加在线摄像装备,对粗轧末道料头部情况进行在线监测,控制剪切。
NM450耐磨板
When discharging, the poor end of the raw material is toward the tail, and the 204 series and 233 series are selectively cut, while the other series are no longer cut, so as to reduce the cutting loss of the head. The roughing pass of 233 and 272 series is optimized to ensure the shape size and reduce the cutting loss. The on-line camera equipment is added at the hot shear to monitor the head condition of the final pass of rough rolling and control the shearing.
3降低切尾
3. Reduce tailing
通过对平板运输机护板改造,减少NM450耐磨钢尾部进入平板机造成的打扭现象,降低尾部切损。同时严肃带钢测量、取样制度,减少取样时造成的尾部切损。
Through the transformation of flat conveyor guard plate, the twisting phenomenon caused by nm450 wear-resistant steel tail entering the flat conveyor is reduced, and the tail cutting loss is reduced. At the same time, strict strip measurement, sampling system, reduce the tail cutting loss caused by sampling.
4降低小卷带
4. Reduce the small coil
提高换辊后的调整技能,取消原换辊后试轧小样的规定,杜绝小卷带的产生。
Improve the adjustment skills after roll change, cancel the original regulations of trial rolling sample after roll change, and eliminate the generation of small coil.
