Refractory Cement Export Ireland

June 16, 2021May 18, 2020 by rsrefractorycastable

Refractory cement is also called aluminate cement or high aluminum cement. Aluminate cement is a hydraulic cementing material made by calcination of bauxite and limestone with calcium aluminate as the main component and alumina content of about 50%. Aluminate cement is often yellow or brown, there are also gray. The main minerals for the refractory cement export are monocalcium aluminate (CaO·Al2O3, CA for short) and other aluminates, as well as a small amount of dicalcium silicate (2CaO·SiO2).

This series refractory cement used for cementing all kinds of refractory aggregate (such as corundum, calcined high bauxite, etc.), to make refractory mortar or concrete, used for lining industrial kiln. Refractory cement forms a low eutectic substance under the action of high temperature. When the refractory castable is configured, too much addition will reduce the high temperature performance of the castable. Silica powder can be used to replace the refractory cement in general production.

Refractory cement refers to cement with a fire resistance not lower than 1580°C. The refractory cement export Ireland is mainly made of bauxite and limestone. The clinker with calcium aluminate as the main component and alumina content of about 50% is calcined and then grinded into hydraulic cementing material. According to the different composition, can be divided into aluminate refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement. Refractory cement can be used to cement all kinds of refractory aggregates (such as corundum, calcined high bauxite, etc.), to make refractory mortar or concrete, used in cement rotary kilns and other industrial kilns as lining.

When the refractory castable is exported, packaging is very important. The quality of packaging directly affects whether the refractory castable can better protect the refractory castable when it is loaded upside down. The export packaging of refractory castable is less strict than that of firebrick. General refractory exported to indiana are packed in ton bags. The material of the ton bag is generally made of woven plastic, which is convenient for the better loading of the refractory castable in the process of transportation and packaging.

When the refractory castables is delivered, it is usually packed in bulk. Generally, each small bag is 25kg and 50kg. This is convenient for calculation and packaging. The small bags are usually packed in woven bags with plastic film to protect the refractory castables from moisture. The package can be completed by placing 20 or 40 small bagged bags of refractory castables into a large ton bag.

The package of refractory castable is usually packed in ton bags. If the customer needs to use pallet packaging, the small bag of refractory castable shall be placed on the pallet. After the package is finished, the package shall be wrapped with moisture-proof plastic wrap film. When pallets are used to transport refractory castables, the pallets need to meet export requirements. When refractory exported to indiana, the first is that the packaging of refractory castables should be in accordance with the requirements for easy transportation, so as to avoid the breakage of ton bags or pallet damage in the process of transportation. Second, refractory castable to conform to waterproof and moistureproof.

Corundum Castable and Corundum Mullite Castable Difference

June 16, 2021May 8, 2020 by rsrefractorycastable

Corundum castable has a higher aluminum content and a higher price than ordinary castable, but good refractory products have a longer service life than other refractory castables. Corundum castable manufacturing quality is stable and reliable, worthy of customer trust, welcome to purchase.

The common corundum castable mainly includes two kinds of corundum refractory castable and corundum mullite refractory castable. Both types of refractory castables contain corundum, but they differ greatly in terms of performance. Below we introduce the concrete difference of these two kinds of refractory castable for everybody.

The corundum contained in the preparation of rigid jade refractory castable is a kind of trigonal crystal system, the crystal type is generally short columnar, and the corundum itself also has high thermal conductivity and electrical insulation properties, excellent chemical stability and resistance to reducing agents. Therefore, corundum is an advanced refractory material in the amorphous refractory. Corundum castable manufacturing is generally made of industrial alumina or bauxite after sintering or electric melting, so industrial use belongs to artificial corundum, but the density and hardness of artificial corundum are relatively large, the use effect is also relatively significant.

Corundum mullite refractory castable is made with less mullite in nature, and the mullite used in industry is artificially synthesized. It has the characteristics of high purity, high density, good structure, low creep rate, small thermal expansion, good thermal shock resistance and strong chemical erosion resistance. It is widely used in the refractory industry, and the development is relatively rapid, but if you compare corundum and mullite, the hardness and true density of corundum is much better than mullite.

The difference between corundum castable manufacturing and corundum mullite is actually in terms of performance. Corundum mullite refractory castable is mainly of good wear resistance and fire resistance, while corundum mullite refractory castable is mainly of good thermal shock resistance, the aluminum content of corundum mullite castable is not as high as that of corundum high strength castable. But the corundum mullite castable is more flexible.

High Strength Abrasion Resistant Castable Advantage

1. The low content of cement in the wear resisting material, that is, the low content of calcium oxide, reduces the production of low melts in the material, thus improving the product’s refractoriness, high temperature strength and slag resistance;

2. The mixing water consumption of this refractory material is only about half of that of ordinary castable, so the density of castable is increased and porosity is reduced.

3. After forming and curing abrasion resistant castable manufacturing, the generated cement hydrate is less. During heating and baking, there is no large amount of water leakage, which reduces the strength of the medium temperature.

Abrasion resistant castable manufacturing should pay attention to strictly control the proportion of water added in the construction, the product should be used in the whole package, should be used in time after mixing, if not used in time, it is prohibited to use. And after pouring construction to do the maintenance work, in strict accordance with the oven curve for baking.
