Low Cement Castable For Heating Furnace

June 16, 2021November 22, 2019 by rsrefractorycastable

Low cement castable refers to the refractory castable combined with calcium aluminate cement, the castable with CaO content less than 2.5%, and the castable with the content of calcium aluminate cement about 1/2 to 1/3 of that of ordinary calcium aluminate cement castable. Low cement castable characteristics outstanding, high quality, favorable price.

According to the operating conditions of the heating furnace, the characteristics of the low cement castable used are described below.

1. Good thermal shock stability

The content of low cement castable Al2O3 is 55%-67%. After drying and firing at 1400℃, the compressive strength is 15-30mpa and 40-65mpa respectively. Compared with low cement castable with high aluminum content and strength, its thermal shock stability is better.

2. It has micro-expansibility

In the low cement castable add appropriate amount of expansion agent and materials containing aluminum and silicon, so as to produce micro-expansion when using, to prevent the formation of cracks.

3. Good sintering performance

By adding proper amount of sinter and other materials into the low cement castable, the working layer of the wall can be sintered and formed as a whole in the process of using at 1000-1350℃, so as to adapt to the working conditions of its double-sided heating.

In the low cement castable matrix, most of the calcium aluminate cement is replaced by superfine powder with the same or similar chemical composition as the main material of the castable. Therefore, this series of refractory castable is a kind of refractory with hydration and aggregation.

The low cement castable characteristics of prominent. After casting molding, less cement compounds are generated during curing, and there is no large amount of hydration bond damage during heating and baking, resulting in the decrease of strength at medium temperature.

Low cement refractory castable is mainly used in metallurgical, petrochemical, mechanical manufacturing, electric power and building materials industrial kilns. Now this refractory castable has replaced the traditional fired refractory as the backing. Low cement castable manufacturing can also be used for heating furnace, heat treatment furnace, electric furnace cover, shaft kiln, rotary kiln, blast furnace iron ditch, ladle, ladle lining.

This series of refractory castable is supplied in the form of scattered dry powder. In construction, clean water is added according to the requirements. After stirring, it can be vibrated or rammed. High temperature performance of low cement castable, high strength, wide range of temperature, basically no shrinkage after high temperature, overcome the previous characteristics of refractory concrete shrinkage. Easy to store, transport and use.

Low cement castable manufacturing is widely used in power plant, boiler, melting furnace, heating furnace, soaking furnace, heat treatment furnace and induction furnace lining different parts. It has the characteristics of anti – penetration, anti – erosion, anti – impact, anti – wear, good mechanical properties, strong structural integrity of furnace body, air tightness is better than brick furnace. The service life is prolonged, the cost of repairing furnace is saved, and the economic benefit is remarkable.

Advantages of low cement castable:

1. The low content of CaO in the castable can reduce the formation of low eutectic phase in the material. Thus the fire resistance, high temperature strength and slag erosion resistance are improved.

2. During construction, the mixing water consumption of low cement castable is only 1/3 to 1/2 of that of ordinary castable. Therefore, the porosity is low and the volume density is high.

3. After pouring molding, the cement compound generated in curing is less, and there is no large amount of hydration bond destruction during heating and baking, which leads to the decrease of the medium temperature strength. However, the strength gradually increases with the increase of heat treatment temperature.

4. The strength composition of the refractory castable can be properly adjusted to be composed of artesian castable and pumped castable.
