04 5月 Silicate Tap Hole Cone
Silicate Tap Hole Cone does not affect the aluminum alloy composition.
1. Using melting method: Mix kaolin, alumina and silica in a certain proportion, put them in an electric arc furnace or resistance type electric furnace and melt at a high temperature above 2000 ℃. Formation of fibrosis.
2. Adopt melting method: aluminum silicate fiber is to mix kaolin, alumina and silica according to Al2O3 / SiO2 (mass ratio) 1: 1, put in electric arc furnace or resistance type electric furnace to melt at high temperature above 2000 ℃, melt the melt It flows into the outside of the furnace in a thin stream and blows onto the melt with high-speed airflow to form fibrosis.
And according to the product silica and alumina content for secondary processing to obtain products
3. Vacuum forming method: Using high-quality ceramic fiber cotton as raw material, through vacuum suction filter automatic equipment forming process, it has excellent high temperature performance and self-supporting strength.
The aluminum silicate fiber contained in Silicate Tap Hole Cone, also known as ceramic fiber, is a new type of lightweight refractory material, which has:
Light weight, high temperature resistance, good thermal stability, low thermal conductivity, small heat capacity, good resistance to mechanical vibration, small thermal expansion, good thermal insulation and other advantages.
Silicate Tap Hole Cone Product Advantages
The high-aluminum fiber is vacuum-sucked and shaped, without sticking to aluminum and slag.
The mass is evenly distributed with good elasticity, tight blockage and stable flow control.
High hardness and long service life.
