生产优质大截面模块的锻造工艺

Forging Technique for Producing Big Section High Quality Block

钢锭内部缺陷对大截面模块内部质量的影响较大。莱钢锻压厂在生产中改进加热工艺 ,利用高温扩散部分消除钢锭内部微观偏析 ,同时利用平砧加长及大压下量的开坯 ,有效地锻合了钢锭中负 V型偏析引起的疏松组织 。

The internal defects of steel ingot have bigger influence to internal quality of block.Through improving heating technique using of high temperature diffusion method to eliminate micro segregation in the inner of steel ingot and doing cogging with great reduce ratio,the rarefaction structure caused by negative V segregation in the inner of steel ingot can be eliminated by forge,thus the internal quality of block can be increased.
