The Application Of A Closed Cooling Tower In The Blast Furnace Industry

The cooling furnace cooling equipment (closed cooling tower, evaporation condenser) is an important part of the structure of the blast furnace furnace body.

(1) Protect the furnace shell. In normal production, the blast furnace shell can only work for a long time at a temperature below 80 ° C. The high temperature heat from the furnace is taken away by more than 85%from the cooling equipment, and only about 15%of the heat is lost through the furnace shell.

(2) Cooling and support for refractory materials. The surface temperature of the fire -resistant material in the blast furnace is about 1500 ° C. If there is no cooling equipment, the refractory material will be invaded in a short period of time.

Eclipse or wear. The cooling of the cooling equipment can improve the resistance and abrasion capacity of refractory materials. Cooling equipment can also support the support of the blast furnace, increasing the stability of the masonry.

(3) Maintain a reasonable operation furnace type. The erosion of the refractory material is close to the operation furnace type, which plays a good role in the reasonable distribution of gas flow in the blast furnace and the smooth running of the furnace material.

(4) When most of the refractory materials are eroded, they can continue to maintain the production of blast furnaces by the slag skin on the cooling equipment.
