Low Cement Castable

Low Cement Castable

Short Description:

Low cement castable refers to a castable with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some even reduce to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable.

Description

Low cement castable refers to a castable with a lower amount of cement. The cement dosage of refractory cement castables is generally 15% to 20%, and the cement dosage of low cement castables is about 5%, and some even reduce to 1% to 2%. The purpose of reducing the amount of cement is to improve the fire resistance of the castable.

Low-cement castable is a high-tech refractory developed on common castables by using rheological principles, the tightest packing theory and ultra-fine powder technology. It has the characteristics of low porosity, small pore size, high density, good volume stability, high strength and small water addition, and overcomes the characteristics of a significant decrease in strength of ordinary castables at 800~1200, and increases with temperature And increase, so that the thermal shock of the furnace body can be more than doubled.

Features

High density, low porosity / Good hot strength / High refractoriness and high softness

Resistance to mechanical peeling and impact, strong corrosion resistance and low wear rate.

Application

Low cement castables are widely used in power station boilers and other thermal kilns, front and back arches, furnace roofs, and rear furnace walls. They are suitable for heat treatment furnaces, various heating furnaces, shaft kilns, machinery, iron blast furnace tapholes, Ladle, ladle, etc.
