High Strength Low Cement Refractory Castable For Reheating Furnace

High strength easy Installation low cement refractory castables for reheating furnace

Low cement castable is a kind of refractory cement castable materials, which contains 3~8% cement content and performs variety excellent properties of high strength, low porosity, high density, low abrasion, thermal shock resistance and erosion resistance. Refractory low cement castable is mainly used in metallurgy, electricity, petroleum, chemical industry and other silicate kiln. low cement insulation castable mainly includes high alumina low cement castable, corundum low cement castable and mullite low cement castable, which can be used for furnaces and boilers in different areas according to various composition.

Low Cement Castable Description

Low cement castables are one kind of refractory castable with a high service temperature of over 1550℃, which uses aluminate cement as its binder, in which the amount of CaO is less than 2.5%. Refractory low cement castable composition mainly consists of refractory aggregate, refractory powder and water. Compared with traditional refractory castable, low cement refractory castable 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.

Properties of Low Cement Castable

Low water content.

High refractoriness,

High strength.

Low linear change rate.

High thermostability.

Low porosity and High bulk density.

High temperature strength and slag resistance.

Manufacturing Process of Low Cement Castable

Low cement castable is a castable refractory which is made of ultrafine powder, aluminate cement and some admixtures. Furthermore, the amount of these composite can influence its performance. As for its water amount, given the guaranteed ease of mixing material, adding little water can lower porosity and improve strength. Low cement refractory castable has the advantages of little amount of water, high density and high strength, which is the reason that this refractory material is widely used in many field and various furnaces and kilns.

Advantages of Low Cement Castable

1. High Refractory Temperature and Strength and High Anti – Slag Corrosion Resistance.
2. Low Porosity and High Bulk Density. During the construction process, only 1/3~1/2 amount of water for traditional castable will be added into it.
3. Increasing Strength With The Improving Temperature of Heat Treatment After Casting Into Shape: With proper adjustment of the castable size, it can be mixed into self-flow castable and pumped pouring material.
