1.Alumina cement castables Alumina cement castables are generally used in the low-temperature zone, flue area, and furnace body of heating furnaces with a temperature not exceeding 1300°C. Alumina cement castables are a type of castable produced by mixing various refractory aggregates and powders in a certain proportion using aluminate cement as a binder. They have […]

Industrial heating furnaces are widely used in industries such as metallurgy, petroleum, and chemicals to heat metal materials to temperatures suitable for rolling and forging. The article details the key structures of industrial heating furnaces, including the radiation chamber, convection chamber, waste heat recovery system, burner, and ventilation system. The radiation chamber primarily heats the

As the core equipment of steelmaking, the quality of converter lining construction directly determines the service life and production efficiency of converter. This plan combines advanced domestic and foreign experience to build a systematic solution from three dimensions: material selection, process optimization, and quality control. It focuses on the differences in working conditions in different

The roof of a steel rolling heating furnace can be divided into two types: arched roof and flat roof. The arched roof is built with refractory bricks. Generally, the inner layer is a 232mm or 300mm thick refractory brick layer, and the outer layer is covered with an insulation layer. This type is only used

In modern iron and steel metallurgical production, the ladle plays a vital role as a key equipment connecting the steelmaking furnace and the continuous casting machine. It is not only used to store and transport high-temperature molten metal, but also an important place for molten steel refining, composition adjustment and temperature control. However, the working

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
