ÇUQUNUN SAFLAŞDIRILMA PROSESİNİN SƏMƏRƏLİLİYİNİN ARTIRILMASI

The efficiency of the process of out-of-furnace refining of liquid cast iron by blowing powder impurities has been studied. Studies have shown that the most effective purifier for cast iron desulfurization is a mixture of 59% CaC2, 26% CaCO3 and 15% C. It has been found that when a finely ground slurry of lime is blown into the liquid metal to provide a large interfacial area, the fluidity of the slurry deteriorates. It was determined that the temperature drop of cast iron during processing with lime mixtures increased almost twice compared to the application of carbide mixtures. However, this deficiency was eliminated by adding a surfactant to the lime scrub. Studies have shown that the unfavorable shape of the mixer-chamber does not appreciably affect the mixing results in stable zones. Blowing carbide and lime mixtures into the mixer-cauldron increases the mixing effect by 2-3 times compared to the ordinary cauldron
