Low cement castable manufacturing is aluminate cement as the binder, CaO content less than 2.5% of the refractory castable, collectively referred to as low cement castable. Unlike traditional castables, low cement castables replace most or all of the cement with superfine powder with condensed bond, which has the same or similar chemical composition as the main material.
The low cement castable is often used in the front and back of the cement kiln, the front of the cooling machine, such as high temperature resistance parts and other industrial kiln lining. Low cement castable manufacturing, mainly used in metallurgy, electric power, nonferrous metals, petrochemical, building materials and other industries. For example, the bottom of the glass kiln trough, the front end of the cooling machine of the kiln door cover before and after the cement kiln and other parts of high temperature resistance, the front and rear kiln mouth, coal injection pipe, etc.; Heating furnace, soaking furnace and other heat treatment furnace; Intermediate frequency induction furnace lining, chemical catalytic cracking reactor high temperature wear resistant lining, other industrial furnace lining.
Because the superfine powder has replaced part of aluminate cement, the quality of low cement castable manufacturing products is stable and reliable, the price is reasonable and preferential, and the fire resistance is high. Welcome to consult.
Low cement castable characteristic:
1. Low CaO content, reduce the formation of low eutectic, improve the refractory temperature, compressive strength and slag erosion resistance;
2. Low water consumption, low porosity and high volume density;
3. The high temperature strength increases with the increase of heat treatment temperature.
4. The ratio of particles can be adjusted according to the needs of users and configured into artesian pouring material and pump pouring material;
5. High refractory temperature, high service temperature;
6. According to different materials can be configured clay low cement castable, high aluminum low cement castable, corundum low cement castable;
7. According to the different technological conditions, the vibration type castable and artesian type castable can be made by properly adjusting the particle ratio.
