硅铬合金的质量与微碳铬铁及中、低碳铬铁的质量密切相关。某厂在微碳铬铁生产中由原料带入的磷的分配比为: 可见,硅铬合金及石灰的含磷量是主要因素,制备低磷的硅铬合金则是改善微碳铬铁及中、低碳铬铁质量的关键之一。由于硅铬合金中含硅量高对其实现脱磷则是有利的(因为随着硅含量的增加磷在合金中的活度系数也增加),因此,用处理液
The quality of silicon-chromium alloy is closely related to the quality of micro-carbon ferrochromium and medium-low carbon ferrochromium. The distribution ratio of phosphorus brought by raw materials into a factory in the production of micro-carbon ferrochromium is as follows: It can be seen that the phosphorus content of silicon-chromium alloy and lime is the main factor and the preparation of low-phosphorus silicon-chromium alloy is to improve the micro- Medium and low carbon ferrochromium quality one of the key. It is advantageous because of the high silicon content in the silicon-chromium alloy for dephosphorization (as the activity coefficient of phosphorus increases in the alloy as the silicon content increases), the treatment solution
