The service life of the ramming material of the intermediate frequency furnace

The intermediate frequency furnace ramming material is a semi-dry, bulk refractory material formed by ramming. Usually, the particles and fine powders made of high aluminum materials are made of a certain gradation and added with an appropriate amount of binder. Strong ramming is required to obtain a fine structure. The intermediate frequency furnace ramming material is mainly used for direct contact with the molten material, so the granular and powdery materials are required to have high volume stability, fineness and erosion resistance. The product has good chemical stability, erosion resistance, wear resistance, anti-shedding and thermal shock resistance.

Intermediate frequency furnace ramming material Now, what is the lining material used in the intermediate frequency furnace for copper smelting? Here is a brief explanation: the lining material used in the copper smelting intermediate frequency furnace on the market is generally siliceous Intermediate frequency furnace ramming material.

Because the temperature of copper smelting is relatively low, most of the siliceous ramming materials are used. In addition to the traditional crushing, screening and magnetic separation processes, this ramming material also needs to be dried and washed. The content of silicon in the material is generally above 95. The content of 3 iron oxide is less than 0.5.3 2 aluminum oxide is less than 0.7. The refractoriness is generally 1650 degrees. This product is made of super high alumina bauxite clinker and powder.

As the main raw material, the mixture is composed of pure aluminate cement binder, aluminum powder, kyanite, anti-shrinkage agent, explosion-proof fiber and other admixture materials. , It can also be cast into prefabricated blocks for masonry use.
