Detailed introduction

High Carbon Ferro Silicon is a new type of alloy for converters. It can completely replace Ferro Silicon, Carbon Additive and Silicon Carbide. It is used in converter smelting deoxidation alloying process. Its characteristics: reduce steelmaking cost, increase economic efficiency and improve product quality. , stable performance.

First, the background of high carbon ferrosilicon varieties

For a long time, the alloy for converter has not been adjusted. The traditional alloys have a single structure, that is, Q195 and Q235 steels adopt Mnsi FeSi SiAiCaBa Sic recarburizer process, and HRB335 and HRB400 steels adopt MnSi Fesi AiSi recarburizer production process. However, the traditional silicon-manganese alloy, the ferrosilicon resources are increasingly tight, the market price has climbed all the way, which makes the converter steelmaking cost gradually increase, reducing the profitability of steel, and the recovery rate of the traditional alloy is greatly affected by the converter operation, the amount of steel, The end temperature and the amount of slag make the alloy composition fluctuate greatly in the finished product. The chemical composition of the smelting steel grade is unstable, and the qualified rate of the finished product internal control index is low.

Second, high carbon ferrosilicon variety structure optimization

   1. Conducive to the reduction of production costs.

   2. Improve the quality of molten steel.

   3. Reduce the amount of alloys such as silicon and manganese.

   4. Adjust the main alloy.

High Carbon Ferro Silicon completely replaces Ferro Silicon, Silicon Carbide, and Carbon Additive, reduces the amount of deoxidizer, and performs oxidation alloying on the converter. The effect is stable. The chemical composition, mechanical properties and internal control quality of the steel are superior to the traditional process.

Through experiments and production practices, the use of High Carbon Ferro Silicon for the deoxidizing alloy process of the converter has greatly reduced the cost of steel-making tons of steel, creating considerable economic benefits and improving the market competitive advantage of steel.
