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
Many customers do not know what properties they need to know when buying refractory bricks, and they are afraid that their questions are not professional enough and they cannot buy the right refractory bricks or other refractory materials. In fact, usually refractory bricks and other refractory materials only need to pay attention to the following
Refractory castables are a type of unshaped refractory materials. They are a mixture of refractory aggregates, binders and admixtures, which can be used for construction after adding water (or liquid binder) and mixing. Refractory castables have a certain coagulation and hardening time after construction. Therefore, after casting and forming, they need to be cured for
In addition to price, the selection factors of refractory materials also need to consider the following factors: longer service life; better thermal insulation effect; simpler masonry method and faster masonry speed; fast maintenance speed, etc.Amorphous refractory materials, also known as bulk refractory materials, are composed of bulk particles and fine powders. They do not need
