This article will explain how to make refractory cement and the advantages of using refractory cement. In addition, through this article, learn about the application fields of refractory cement, the composition of refractory cement, and the difference between refractory cement and refractory castables. How to make refractory cement 1.Mix the Portland cement, Perlite, and silica

Heating furnaces are used in petroleum, chemical, metallurgy, machinery, building materials and other industries. The seven commonly used refractory castables for heating furnaces are: low cement, alumina cement, phosphate, mullite, lightweight, anti-dry slag, self-leveling castables. Other refractory materials include refractory fibers, plastics, etc. (1) Low cement castable It is suitable for high temperature and medium

Refractory materials are referred to as refractory materials. Generally, they are made of inorganic non-metallic materials with a refractoriness of more than 1580℃. They can withstand the physical and chemical effects of gases, dust, slag, liquid metal and other substances, and have a certain strength of masonry and knotting performance. If the refractory materials are

In the chemical industry, metallurgy, environmental protection and other highly corrosive industrial fields, acid-resistant refractory castables as a key lining material, its performance is directly related to equipment life and production safety. This paper starts from the principle of material science, combines with engineering practice, systematically elaborates the configuration technology of acid-resistant refractory castables, and

Electric arc furnace cover is an important part of the electric arc furnace lining, the length of life of the cover and its insulation performance is good or bad, on the steel production, quality, consumption and other technical and economic indicators have a very close relationship. Therefore, at home and abroad on the furnace cover

Different refractory materials are suitable for smelting different metals or alloys. At present, medium frequency induction furnaces are widely used in metallurgy and foundry industries. During the use of induction furnaces, the impact, friction and electromagnetic stirring of the charge will aggravate the erosion of the furnace lining. The factors that reduce the service life

Types of steel mill charges and their impact on steel production In the steel production process, the selection of smelting materials is crucial. Different types of smelting materials have a significant impact on the quality, output and cost of steel. Common steel mill smelting materials mainly include the following: Iron Ore This is one of
