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,

Due to the development of clean steel and ultra-low carbon steel and the requirements of energy saving, the development of low-carbon refractories has become an inevitable trend. At present, the main development trend of carbon-containing refractories used in various parts of the electric arc furnace, such as magnesium-carbon bricks, aluminum-carbon materials, Al2O3-MgO-C materials, or other

In traditional processes, the carbon content of magnesium carbon bricks is generally 14%-20%, and the source of carbon is basically from graphite. This is because graphite is resistant to high temperatures, has little mass loss, small volume expansion and contraction, and poor wettability to slag. Traditional magnesium carbon refractory materials will gradually expose the following

Refractory castables are the non-calcined, irregular refractory materials, accounting for 1/3 of the total output of refractory materials in foreign countries. Because the castables can solve some complex parts of the kiln lining problems. Composition of refractory castables Refractory castables consist of a mixture of granular and powdered materials and are available in a wide
