Refractory materials are inextricably linked to the steel industry

Refractory material is a high-temperature resistant product, which can be roughly divided into shaped refractory bricks and unshaped refractory castables. Today we will talk about the application of refractory materials

Refractories are one of the indispensable basic materials in the steel industry, and it can be said that steel smelting is impossible without refractories. The amount of refractory materials in the steel industry accounts for about 70% of the entire refractory production; Similarly, without the development of the steel industry, there will be no development of the refractory industry, so refractories and the steel industry complement each other. The relationship between refractories and the steel industry is mainly manifested in: 1. Refractories as containers for molten steel are an important guarantee for the stability and economy of steel smelting. 2. Refractories play a very important role in ensuring the quality of molten steel. The emergence of a new metallurgical process requires the support of new refractories, and if this new refractory does not appear, it will hinder the development of new metallurgical technologies. Conversely, if there is a refractory suitable for new metallurgical process technology, it will also play a role in promoting the development of metallurgical technology. Therefore, refractories are the basic materials of the steel industry rather than metallurgical accessories.

In the process of steel smelting, if the refractory furnace lining is constantly dissolved by molten steel and enters the molten steel, it will have a certain impact on the quality of molten steel, which is mainly manifested in: 1. It will pollute the molten steel and reduce the quality of steel 2. The service life of the lining is reduced, which has an extremely adverse impact on production efficiency and production costs, so the requirements of the steel industry for refractories should be a new generation of refractory materials with high quality, long life, multi-function, no pollution to molten steel, and low pollution
