Ceramic ball valves applied to Pulverized coal injection system

Ceramic ball valves applied to Pulverized coal injection system Currently, in high furnace of metallurgy technique, techniques of high wind, high temperature, refined steel, injection oxygen enrichment have been widely used to save cost and increase production. Furnace injection techniques have been widely used for some places where lack of coke and small high furnace. Actually, for places where does not lack of coke, high furnace injection has not been adopted. Along with lacking of coke, cost increasing of coke meanwhile [...]
