Abstract

The invention discloses a refractory material, which contains thermally conductive fiber. The refractory material has good thermal conductivity. In addition, the invention also provides a preparation method of the refractory material, a stove kiln with the refractory material, a flash smelting furnace and a smelting system.

Description

technical field [0001] The invention relates to the field of smelting. In particular, it relates to refractory materials and methods for their preparation. 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 1000-1600 °C. Therefore, if the supply of cooling water is a little careless, the pure copper water wall or pure copper water jacket mus...
