What are the classifications of refractory castables?

The material binder (also known as cementing agent) which is composed of refractory aggregate consisting of refractory aggregate and powder.The binder used in the refractory castable for Taurus varies with the properties of the cemented material and the use conditions;According to the binder hardening conditions, there are water, gas and hot bond。
Mainly according to the porosity, binder, aggregate type classification. In actual use, often with the use of temperature or features are classified. According to the porosity of a dense castable and the porosity of not less than 45% of the refractory castable two.According to the bond with hydraulic combined chemical combination condensationbondingare castable. Hydraulic combined with castable hardening at room temperature and hardened by hydration, the main varieties of ordinary portland cement, calcium aluminate cement, calcium aluminate cement, fused calcium aluminate cement castable.Condensationbondingare castable material in the process of calcination after sintering and hardening, the main varieties of clay materials such as casting. According to a refractory clay aggregate (Al2O3 30% ~45%), high alumina aggregate (Al2O3 = 45%), siliceous aggregate (SiO2 = 85%, al2o3<10%), alkaline aggregate (with magnesite, dolomite etc.), special aggregate (carbon, carbides, nitrides of zircon, spinel, etc.) and insulation aggregate (with vermiculite, perlite, ceramsite, cenosphere, light brick sand, clinker porous alumina hollow ball, etc.).In actual use, according to the requirements of the project to allow the use of some kind of mixed aggregate carbon fiber pouring integrated sucker rod centralizer, which belongs to fittings for oil production, including carbon fiber centralizer, sucker rod, carbon fiber sucker rod centralizer and one-time pouring into one. The utility model directly to the carbon fiber centralizer。
Low cement, ultra low cement content are in accordance with the Cao definition, essence is to avoid low cement materials. There are too many Cao into the cement dosage in 3-8% castable is generally between 1-3% CaO content is called low cement castable. While the content of Cao is less than 1% of the castable is called ultra low cement castable.
