◆主要按气孔率、结合剂、骨料品种分类。在实际使用中还经常以使用温度或功能特点

进行分类。

It mainly according to the porosity, binder, aggregate type classification. In actual use, often with the use of temperature or features for classification.

 

按气孔率分 有致密耐火浇注料和气孔率不低于45%的隔热耐火烧注料两种。

 

According to the porosity of a dense castable and the porosity of not less than 45% of the refractory castable two.

  

按结合剂分 有水硬性结合、化学结合、凝聚结合耐火浇注料。

According to the binding agent is a combination of water hardness, chemical combination, condensation combined with refractory casting material.

 

水硬性结合浇注料在常温下凝结硬化并通过水化作用而硬化,主要品种有硅酸盐水泥、普通铝酸钙水泥、纯铝酸钙水泥、电熔纯铝酸钙水泥浇注料等。化学结合浇注料在常温下一般通过加入促硬剂形成化学反应而硬化,主要品种有水玻璃、硫酸铝、磷酸盐浇注料等。凝聚结合浇注料为在煅烧过程中经烧结作用而硬化,主要品种有粘土浇注料等。

 

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. Chemical combination castable at room temperature by adding hardening agent to form a chemical reaction the main varieties of hardening, water glass, aluminum sulfate, phosphate material pouring. Condensationbondingare castable material in the process of calcination after sintering and hardening, the main varieties of clay materials such as casting.


 

按耐火骨料分 有粘土质骨料(Al2O3 30%~45%)、高铝质骨料(Al2O3%26ge;45%)、硅质骨料(SiO2%26ge;85%、Al2O3%26lt;10%)、碱性骨料(有镁砂、白云石等)、特殊骨料(有碳、碳化物、尖晶石、锆英石、氮化物等)和隔热骨料(有珍珠岩、蛭石、陶粒、漂珠、轻质砖砂、多孔熟料、氧化铝空心球等)。

According to a refractory clay aggregate (Al2O3 30% ~ 45%), high alumina aggregate (Al2O3%26ge; 45%), siliceous aggregate (SiO2%26ge; 85%, Al2O3%26lt; 10%), alkaline aggregate (with magnesite, dolomite etc.), special aggregate (carbon, carbides, spinel, zirconium nitride and stone, etc.) insulation aggregate (with vermiculite, perlite, ceramsite, cenosphere, light brick sand, clinker porous alumina hollow ball, etc.).
