SYSTEM FOR SUPPLY OF HOT BLOWING

摘要

The invention relates to ferrous metallurgy, in particular to a construction of air-heater blocks and can be used at heating of blast-furnace blowing. A system for supply of hot blowing consists of a collector of hot blowing connected to each form air-heaters of group, air-pipe of cold blowing connected to ring pipeline of blast furnace and mixing air-pipe of cold blowing equipped with mixing valve and connected with air-pipe of hot blowing and also air-pipe of cold blowing. The collector of hot blowing additionally has tap of hot blowing, connected with the middle of collector of hot blowing and with connecting point of mixing air-pipe of cold blowing with air-pipe of hot blowing. The invention provides the possibility of qualitative stabilization of temperature of hot blowing.
