Refractory material made by mixing refractory aggregate with a certain particle size gradation, powder, binder,Unshaped refractory and admixture,Unshaped refractory also known as bulk refractory. Used for the lining of thermal equipment, directly baked and used without the firing process. Compared with refractory bricks,Unshaped refractory it has the characteristics of simple process (due to omission of firing process), energy saving, low cost,Unshaped refractory and easy mechanized construction. The effect of using on some thermal equipment is better than refractory bricks.
Its particles and fine powder can be composed of refractory materials of any material,Unshaped refractory and can be divided into: siliceous refractories, clay refractories, high alumina refractories, magnesia refractories, dolomite refractories, chromium Quality refractories, etc. There are many types of binders, such as various cements, inorganic salts (water glass, sulfate, phosphate, etc.) Unshaped refractory and organic substances (tar pitch, phenolic resin, etc.), which can also be classified and named accordingly.
According to process characteristics, it can be divided into castables, plastics, ramming materials, spray materials, projection materials, refractory mud, refractory coatings,Unshaped refractory etc. Usually it can be prepared only through the preparation of granular and powdered materials and the mixing process of the mixture. The process is simple,Unshaped refractory the production cycle is short, the heat energy consumption is low, the integrity is good when used,Unshaped refractory the adaptability is strong, and the comprehensive use effect is good.
Production method: The method of manufacturing unshaped refractory material. There are ramming molding, vibration molding and spray molding. When the brick masonry or the overall structure of the refractory brick is partially damaged,Unshaped refractory the material can be replaced or sprayed or projected equipment can be used for cold and hot repairs,Unshaped refractory which is quick and economical. According to its material characteristics, it can also be used as the lining of various parts of the kiln and the protective layer and joint material of the masonry.
A material with good fluidity after adding water and stirring. After molding,Unshaped refractory it needs to be properly cured to make it coagulate and harden,Unshaped refractory and it can be used after baking according to a certain system.
The casting material uses aluminum silicate clinker,Unshaped refractory corundum material or alkaline refractory clinker as the aggregate; the lightweight casting material uses expanded perlite, vermiculite, ceramsite,Unshaped refractory and alumina hollow spheres as the aggregate. The binding agent uses calcium aluminate cement, water glass, ethyl silicate, polyaluminum chloride,Unshaped refractory clay or phosphate, etc. The admixture depends on the use situation,Unshaped refractory and its function is to improve the construction performance and improve the physical and chemical properties.
