Description

The cover part of the induction furnace is mainly casted on the steel structure with castables.

The refractory material is high-alumina castable; the furnace mouth is rammed with plastic or prepared into prefabricated parts,the refractory materials are mostly mullite, corundum or chromium corundum plastics.

The refractory material used for the lining of the induction furnace is ramming material, while the dry ramming material does not contain liquid binder.

A series of advantages, such as short drying and sintering time, good stability and convenient furnace dismantling, are adopted by most induction furnace manufacturers

Recognized. The smelting of cast iron generally uses acidic siliceous ramming material, while the smelting of steel follows the metallurgical method (acid and alkali slag) Induction furnace lining materials can be divided into acid refractory materials, neutral refractory materials and alkaline refractory materials.

Acid slag is made during acid smelting. The refractory materials used are mainly quartz sand, zircon, silica ramming materials can be used in a variety of induction furnace lining materials, the limiting factors are mainly refractoriness and pure degree; alkaline slag is made during alkaline smelting. The refractory is neutral, alkaline refractory or graphite crucible.

Alkaline ramming materials are mostly used in magnesium, with excellent corrosion resistance, high load soft temperature, and no melting with alkaline slag or body reaction and other advantages, but thermal stability and thermal shock stability are a major disadvantage, adding white corundum powder or spinel stone micropowder can increase the service life; the neutral and spinel linings have the advantages of corundum lining and magnesia lining.

It is the development direction of large and medium-sized lining and high-temperature lining.

The smelting lining of non-ferrous metals copper, aluminum and their alloys usually use acidic silicon ramming material or neutral corundum.

The quality is mullite, etc., which is desirable for good results.

Coil slurry adopts corundum to apply slurry; furnace lining repair material adopts chromium containing corundum or high aluminum plasticity material; backing material choose asbestos layer or mica paper.
