Refractory castables, as an indispensable refractory material, have strength characteristics that are directly related to their quality and performance. In many industrial fields, such as metallurgy, cement production, glass manufacturing and chemical industry, castables play a pivotal role. Therefore, the research and development of high-performance castables is particularly important. Aluminum-magnesium castables are particularly worth mentioning, […]

Requirements for refractory mortar in refractory brick masonry (1) The working conditions of the mud in the joints of refractory masonry bricks are exactly the same as those of refractory bricks. Therefore, the main technical indicators of the two, refractoriness and chemical composition, should also be the same or compatible. (2) The type and brand

Ladle, also known as steel barrel, steel tank, big bag, etc., is a container for storing, transporting and processing molten steel. It is an important equipment for refining tasks. The ladle has two main functions: the first is to receive molten steel; the second is to perform refining outside the furnace. With the diversification of

Steelmaking refractories include the lining of liquid iron, liquid molten steel containers and related furnace protection and heat preservation materials, which can be specifically divided into ladle lining, converter lining, ladle lining and intermediate ladle lining and related supporting steel outlet, sliding water outlet, continuous casting of the three major pieces of fixed refractory materials,

The development of induction furnace and the progress of refractory material technology is closely related to the design of large-scale industrial crucible induction furnace is often first from the choice of refractory materials and furnace lining simulation test. Trench induction furnace capacity increase, the expansion of the scope of application (from non-ferrous metal melting to

Medium frequency furnace furnace lining materials, also known as medium frequency furnace refractory materials, medium frequency furnace dry vibration material, medium frequency furnace knotted material, medium frequency furnace pounding material, divided into acidic, neutral, alkaline furnace lining materials, acidic furnace lining materials are based on high purity quartz, fused quartz as the main raw material,

The bottom of the electric furnace and the embankment slope together constitute the molten pool, and its refractory material is directly subjected to high-temperature heat load and slag erosion. Steel flushing, mechanical impact of scrap and oxidation and reduction operations in the furnace at high temperatures make the slag penetrate to the bottom of the

Electric arc furnace is a kind of electric furnace that utilizes electric arc energy to smelt metal. Industrial application of electric arc furnace can be divided into three categories: the first category is direct heating type, the arc occurs in the special electrode rod and be melted between the charge, the charge is directly subjected

In the powder metallurgy furnace lining refractory material selection, its refractory materials have many categories, mainly heavy refractory bricks, including refractory clay bricks, high alumina bricks, silica bricks, fused corundum bricks, silicon carbide bricks, carbon bricks and so on. 1.Clay Brick Clay brick is composed of refractory clay or kaolin (mainly composed of Al2O3, SiO2,
