Mullite castable in refractory cement
By Email:pelletmachine AT aol.com; info AT cs-machine.com
Brief introduction:
Refractory materials can be divided into shaped refractory products(Such as: Refractory brick ,Fire clay brick,High alumina brick, Heat insulation brick,Ceramic fiber products ect) andunshaped refractory materials(Such as:Refractory castable, Plastic refractory, High temperature refractory mortar ect), Widely used in metallurgy, petroleum, chemical industry, Cement, Glass, Casting,carbon,building materials, machinery processing, military, etc.
Refractory raw material: The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite
Made process:
Made from the natural high quality bauxite, our product is through multi-level homogenozaotpm and then calcined at about 1750 degree. it possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to cheamical corrosion, it is an ideal raw aterial for the following refractory products like a variety of shaped and unshaped refractories, advance ceramic asanitary ware body, precision casting models and so on.
Application: metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.

Features: High strength, good thermal stability, impact resistance, scouring resistance, wear resistance, long service life by the combined technology of low cement and adding superfine powder and efficient dispersant. Excellent raw materials and high temperature performance, castable refractoriness reaches 1790 °C. Mixing by machine, convenient construction, the construction period is greatly shortened, and the economic benefit is remarkable.
Purposes: Cement kiln preheater lining, cooling machine lining, pipe lining, coal injection gun wrapping, kiln mouth, and high temperature parts. Prefabricated into various sizes and also can be applied to spraying construction (preheater lining).
Usage: add water to form mortar or make prefabricated block, semi-dry method spraying construction is available for spraying type.
Storage: 25 kg/bag sealed packaging at room temperature for 3 ~ 4 months
