Different from traditional refractory castable, the ultrafine powder with the same or similar chemical composition with the main material of castable is used to replace part or most of calcium aluminate cement in the substrate of low-cement refractory castable.

Low cement castable has many advantages, among which low CaO content can reduce the formation of low eutectic phase in the material, thus improving the refractoriness, high temperature strength and slag erosion resistance. We are the high quality cement castable supplier, the product variety is complete, welcome to consult and buy.

The mixed water consumption of this series of refractory cement castable during construction is only 1/3~1/2 of that of ordinary castable, so the porosity is low and the volume density is high. After it is poured into shape, the cement compounds generated in the curing are less, there is not a large number of hydration bond destruction during heating and baking, which leads to the decrease in the temperature strength, but with the increase of heat treatment temperature, the strength is also gradually increased. With proper adjustment of the strength composition of the low cement castable, the artesian castable and the pump castable can be prepared. We produce low – cement castable widely used, stable and reliable quality, reasonable price.

Characteristics of low cement castable:

1. The outstanding feature of low cement refractory castable is density and high strength, which brings benefits for use. But brought trouble to bake, bake namely improper, easy occurrence flaking or blast crack phenomenon. Therefore, it is very important to make a reasonable oven curve and to use excellent explosion-proof admixture, so as to make refractory castable molding weight of water.

2. Low cement castable is a kind of high technology refractory developed on ordinary refractory castable by using rheological principle, most compact packing theory and ultrafine powder technology. It has the characteristics of low porosity, small pore size, high density, good volume stability, high strength and small amount of water. And overcome the ordinary castable strength at 800 ~ 1200℃ significantly decreased characteristics.

3. Different from ordinary refractory castable is low cement, ultra-low cement castable is to use and castable main material chemical composition is the same, or similar to the ultrafine powder to replace part or most of calcium aluminate cement, while adding trace dispersant (water reducer) and a certain amount of delayed coagulant. The cement-free castable is completely made of ultrafine powder or oxide sol.

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.

The construction performance of refractory castable is closely related to the process of calcium aluminate cement manufacturing. At the same time, the balance of construction performance and strength is also related to the control of calcium aluminate cement hydration process.

Calcium aluminate cement manufacturing is natural bauxite or industrial alumina and calcium carbonate (limestone) according to a certain proportion of the cooperation, calcined or electrofused and made, also useful iron bauxite and limestone through melting and made. Product quality is stable and reliable, welcome to consult and buy.

Generally speaking, the setting and hardening rate of calcium aluminate cement are also related to the curing temperature. With the increase of curing temperature, the setting and hardening rate of CA2 minerals is accelerated, while CA minerals are somewhat abnormal, which are relatively fast at about 20℃, slow at 30℃, and fast at higher than 30℃. According to the phase transition of calcium aluminate hydrate during heating, it is very important to choose suitable curing conditions. Because the hydration of calcium aluminate cement results in different hydrates with different curing conditions.

This series of refractory cement is widely used in metallurgy, chemical industry, petroleum, electric power, machinery, building materials and other industrial kilns and high temperature equipment. It has a good resistance to sulfate corrosion, good waterproof performance, high early strength, setting and hardening fast and other advantages, all products our company before the delivery of strict quality control, welcome to consult and purchase.

In general, after adding steel fiber, the thermal shock performance of castable is also improved. Steel fiber castables prevents fracture or spalling under the action of preventing microcrack and mechanical stress.

For steel fiber, generally use to join the crescent – shaped straight steel fiber. This kind of fiber can increase the contact area between steel fiber and castable, increase the friction force, and not affect the mixing and stirring performance.

It is worth noting that the use effect of steel fiber refractory castable is closely related to the production process, we should accurately according to the conditions of use, add the appropriate proportion of steel fiber, can not add excessive.

During the construction of this series of refractory castables, first of all, dry castables should be mixed and then mixed evenly, and then steel fiber should be added to stir. In this way, the steel fiber will not bend because of repeated stirring. If it is vibration molding, it is necessary to use attached vibrator, can not use insert vibrator construction, otherwise, will destroy the uniform distribution of steel fiber.

High aluminum refractory castable has high cold and hot strength, good wear resistance, heat shock resistance, anti-spalling, good volume stability at high temperature, long service life, etc. It is widely used in two-stage reformer, gas pipeline of gasifier, hydrogen reformer, sulfur recovery device, flue, cement kiln tail, kiln head cooling machine, blanking machine, etc.

High alumina refractory castables has been widely used and achieved good results, making significant contributions to the steel industry and other high temperature industries. The refractory castable with high aluminum and low cement is widely used in the lining of heating furnace, lining of ladle and middle coating, working layer of molten iron and lining of cement rotary kiln. There are many factors influencing the properties of high alumina refractory castables, such as powder, binder and dispersant. In addition, material quality and water content are also important factors.

It is worth noting that the water content not only reduces the total porosity of the high alumina refractory castables, but also speeds up the early hydration of aluminate cement, resulting in less bound water in the hydrate and an increased capacity per unit cementing, thus contributing to its strength at room, drying, and medium temperatures.At low temperature, the total porosity of high aluminum castable is close to that of ordinary castable, while at high temperature, the change of high aluminum refractory castable is not significant, and the increase of ordinary castable is nearly 4%.
