The dust removal system in the production area has been upgraded completely.

In smelting, it is necessary to pay attention to and master the change of silicon content of ferrosilicon in order to prevent waste products. Therefore, it is necessary to correctly grasp the change trend of silicon content and adjust the silicon content appropriately.

Carburizing agent has played a qualitative role in the production of different casting parts, so how to improve the absorption rate of carburizing agent in medium frequency furnace?

The production of qualified carburizing agent must go through strict material selection, and then through high temperature graphitization treatment, in the process of not only sulfur, gas (nitrogen, hydrogen, oxygen >, ash, volatile, moisture and other impurities reduce, its purity will be improved.

Refractory mud preparation: the phosphate fire mud and graphite powder according to the ratio of 2:1 poured into the mud hopper, the powder has lumpy particles or debris must be cleaned, evenly stirred and diluted with 20% water, mixed evenly, and covered with plastic paper to prevent dust, debris, etc. from entering the refractory sludge.

The use of carburizing agent should try to put the carburizing agent in the lower part of the furnace, plus other charges. This can reduce the carburant spillover, but also improve the carburant and liquid iron contact surface, so as to improve carburizing efficiency.
