Abstract

The invention discloses a kiln and a cooling method thereof, and also discloses an ironmaking blast furnace, a flash smelting furnace and a smelting system provided with the kiln. The kiln includes: a kiln shell; a water shower, the water shower is arranged on the outer wall of the kiln shell, and the water shower sprays cooling water to the outer wall of the kiln shell to cool The kiln shell; and a refractory inner lining, the refractory inner lining is arranged on the inner wall of the kiln shell. The kiln according to the embodiment of the present invention has the advantages of low manufacturing cost and stable operation.

Description

technical field [0001] The invention relates to the fields of metallurgy, chemical industry and refractory materials, in particular to a novel furnace. In addition, the invention also relates to a flash smelting furnace, an ironmaking blast furnace and a smelting system having the kiln. Background technique [0002] The development of process intensification technology has caused serious damage to the lining of high-temperature furnaces used in iron and steel and non-ferrous metallurgy. At present, the inner walls of high-temperature furnaces are built with expensive high-grade refractory bricks, and high-temperature furnaces must also be inlaid with more expensive pure copper water walls or pure copper water jackets, which greatly increases the cost of high-temperature furnaces. manufacturing cost. [0003] In addition, although pure copper has good thermal conductivity, its melting point is only 1083°C. The temperature in the high-temperature furnace is as high as 1000-...
