Low Cement Castable Which Widely Used In Casting Low Temperature Zone Of High Temperature Kilns And Stoves


Low Cement Castable is a kind of refractory castable with a high service temperature above 1550℃, which uses aluminate cement as binder, content of CaO less than 2.5%. Low cement castable composition mainly consists of refractory aggregate, refractory powder and water. Compared with traditional refractory castable, it has a series of good performance such as low cement, low porosity, good volume stability and high cold-curing-strength. And also low cement castable density is higher than other refractory castables.

Features Of Low Cement Castable

  • High refractoriness, High refractoriness under load

  • Good slag resistance and corrosion resistance

  • High strength and wear resistance

  • Good thermal shock stability

  • Good hot strength

What are the commonly used low cement castables?

Low-cement castables can be made into high-aluminum low-cement castables, corundum low-cement castables, aluminum-magnesium spinel low-cement castables, etc. according to the fireproof raw materials used. According to the construction characteristics of the project, it can be divided into self-flowing low cement castable and vibrating low cement castable.

The main uses of low-cement castables cover a wide range, and the key points are:

Low cement castables are suitable for heat treatment furnaces, various heating furnaces, heating furnace covers, shaft kilns, machinery, iron blast furnace tapholes, ladle, molten iron ladle, etc.; self-flowing low cement castables are suitable for metal materials The lining of high-temperature fireproof prefabricated components of outer wall rock wool board, such as the outer lining of the water pipe for the water-cooling heat dissipation of the heat treatment furnace, the lining of the overall spray gun for the spouting metallurgical industry, the lining of the prepreg pipe of the RH and DH vacuum pump degassing device, and the ladle Gas circuit components and high-temperature wear-resistant linings of catalytic cracking tubular reactors of petrochemical equipment; they are mostly used for structural analysis of location engineering construction, which can further improve the overall application effect
