What are the requirements for refractory materials in the iron and steel industry?

The focus of China's steel industry is shifting to the development of a new generation of continuous, compact and efficient steel smelting processes. The main contents of the new generation of domestic steel smelting process are:

High-efficiency and low-cost clean steel production technology integration, optimization of product structure, production of clean steel, pure steel and other high value-added products: smelting reduction ironmaking-refining-near-final continuous casting compact steel smelting process, reducing resources consumption and negative impact on the environment.

Therefore, the specific requirements for refractory materials should be a new generation of refractory materials with high quality, long life, multi-function, no pollution or low pollution to molten steel.
