Medium frequency melting furnace cast iron is the development direction

Compared with cupola, using medium frequency furnace iron liquid, can reduce pollution of the environment, is advantageous to the liquid iron quality control, investment is less, and can be easily for nodular cast iron, vermicular cast iron and grey cast iron and other cast iron grade of production, mode of production is very flexible. Compared with using mainly iron ingredients melting scrap steel carburization process smelting iron liquid, can reduce the cost of iron liquid, 1000 yuan.
Medium frequency furnace melting iron liquid, after crushing, processing clean blasting foundry return, can significantly improve the quality of molten iron, reduce energy consumption of molten iron. Our foundry in 10 t worked as a production test on the intermediate frequency furnace, using clean furnace charge back, in the production of high-power diesel engine cylinder head, casting blowhole rejection rate was 6% lower, liquid iron smelting consumption reduce 90 kw · h/t; At the same time can effectively reduce the labor intensity of workers, grilled slag, improving casting smelting operation environment, reduce the slagging phenomenon of power frequency furnace throat opening, solve the problem of difficult after the oven slagging, prolonging the service life of power frequency furnace lining 20%, improve the efficiency of smelting production. Therefore, using medium frequency furnace melting iron liquid, to attach great importance to purification of furnace charge, especially back to the burden of crushing, blasting purification treatment, which is play the efficiency of the intermediate frequency furnace smelting iron a very important link.
