Refractory materials for induction furnaces

Refractory materials for induction furnaces:

The furnace lining is usually made of clay brick or ternary high alumina brick masonry. The bottom of the furnace is sometimes the first high-alumina refractory castable watering grass, and then in the high aluminum brick. When the induction furnace capacity is less than 10t, the lining can be made of high alumina refractory castable or refractory ramming material with about Al2O3 content of about 75%. It can also be made of corundum refractory castable or dry vibration material. Stove sensor coil around the lining, the general use of corundum refractory castable as a whole watering or vibration with dry vibration compact. As the type of raw materials and operating conditions are different, the furnace life is also different, the general furnace age of 0.5 to 4 years. In the use of the coil around the coil and other vulnerable parts should be carried out 1 to 5 times minor repair.

Insulation materials for holding furnaces and aluminum tanks:

Aluminum insulation furnace is divided into slot induction furnace, resistance heating pool furnace and gas furnace furnace. The working temperature of such equipment due to lower operating temperature, generally with clay refractory brick and other materials for the lining, also obtained a higher service life.

Refractory material for rotary drums:

The non-working layer of the drum is made of clay or heat-resistant brick or floating brick masonry, and can also be made of lightweight refractory castable with a bulk density of 1.0g / cm3 or made of prefabricated masonry. The working layer is made of dense clay refractory bricks or Al2O3 content of more than 55% of high alumina refractory masonry. Rotor furnace furnace age is generally 300 ~ 500 furnace times. When the addition of salt solvent smelting aluminum, due to increased chemical erosion, the furnace age has decreased.
