Low cement castable sales

The low cement castable feature are remarkable. Due to the low CaO content in low cement castable, the formation of low eutectic phase can be reduced, and then the refractoriness, high temperature strength and slag resistance are improved.

The water consumption of low cement castable during construction is only 1/3~1/2 of that of general castable, so the porosity is low and the volume density is high. After the series of refractory castable is poured into shape, the cement compounds generated in the maintenance are less, and there is not a lot of hydration bond damage during heating and baking, which leads to the decrease of the medium temperature strength. According to the summary actually follows the progress of heat treatment temperature, the strength of low cement castable also advances gradually. Its strength composition can be properly adjusted to prepare the self – flow castable and pump pouring castable.

As we know, this series of refractory castable is made by using refractory aggregate and powder as refractory materials, adding binder and additives, and after mixing. The binder commonly used in castable is aluminate cement. The amount of cement added can affect the overall performance, high temperature strength and anti-erosion ability of castable. Low cement castable feature prominent, you are welcome to consult the purchase.

Zhengzhou Rongsheng Kiln Refractory Co.,Ltd. is professional refractory castable cement manufacturer, production automation degree is high, the product type is complete, welcome the general user to come to the consultation, we will serve you wholeheartedly.

Low cement castable manufacturing is aluminate cement as the binder, CaO content less than 2.5% of the refractory castable, collectively referred to as low cement castable. Unlike traditional castables, low cement castables replace most or all of the cement with superfine powder with condensed bond, which has the same or similar chemical composition as the main material.

The low cement castable is often used in the front and back of the cement kiln, the front of the cooling machine, such as high temperature resistance parts and other industrial kiln lining. Low cement castable manufacturing, mainly used in metallurgy, electric power, nonferrous metals, petrochemical, building materials and other industries. For example, the bottom of the glass kiln trough, the front end of the cooling machine of the kiln door cover before and after the cement kiln and other parts of high temperature resistance, the front and rear kiln mouth, coal injection pipe, etc.; Heating furnace, soaking furnace and other heat treatment furnace; Intermediate frequency induction furnace lining, chemical catalytic cracking reactor high temperature wear resistant lining, other industrial furnace lining.

Because the superfine powder has replaced part of aluminate cement, the quality of low cement castable manufacturing products is stable and reliable, the price is reasonable and preferential, and the fire resistance is high. Welcome to consult.

Low cement castable characteristic:

1. Low CaO content, reduce the formation of low eutectic, improve the refractory temperature, compressive strength and slag erosion resistance;

2. Low water consumption, low porosity and high volume density;

3. The high temperature strength increases with the increase of heat treatment temperature.

4. The ratio of particles can be adjusted according to the needs of users and configured into artesian pouring material and pump pouring material;

5. High refractory temperature, high service temperature;

6. According to different materials can be configured clay low cement castable, high aluminum low cement castable, corundum low cement castable;

7. According to the different technological conditions, the vibration type castable and artesian type castable can be made by properly adjusting the particle ratio.

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.
