High-strength High-aluminum Castable by RS High-aluminum Refractory

-
High-strength High-aluminum Castable is a relatively common type of wear-resistant castable. It is based on high-quality corundum alumina and other aggregates and powders, and it is configured by adding a binder (heat-resistant stainless steel fiber) and an admixture. This wear-resistant castable has many excellent characteristics, such as good abrasion resistance, high thermal shock resistance, and stability at high temperature. For high-strength and high-aluminum castables, it is necessary to check whether the mold equipment is firm and reliable during the pouring construction. If slurry leakage or voids are found, the castables within the appropriate range should be removed in time and refilled.
 
Wear Resistant Castable
High strength and high aluminum castable

High-strength and high-aluminum castable has excellent corrosion resistance. Therefore, it can not only meet the requirements of corrosion prevention in the corrosive environment, but also meet the long survival time in the harsh environment. The shrinkage, hardness, toughness, wear resistance, and temperature resistance of the high-aluminum castable itself have laid a solid foundation for survival in harsh environments.

Application of high strength and high aluminum castable

The application range of high-strength and high-aluminum castables is very wide.

1. Compared with pulverized coal furnaces, fluidized bed boilers: There are many more places and quantities of castables. Due to poor selection of materials and unreasonable construction process, the temperature control in the oven and ignition start is improper (heating and cooling too fast). Factors such as the evaporation of water vapor in the refractory cannot be discharged in time, which will cause the refractory lining to crack and fall off.

Therefore, the castable should be used at room temperature, and it is possible to use less cement. However, if cement is really needed to increase the compactness or it is necessary to use it during construction, we can choose refractory powder to mix it in.

2. The high aluminum castable has a very high practical rate in China's industry and has high practical value. We all know that the vent holes of the ventilated bricks are obtained by using very thin heat-resistant steel pipes or reasonable particle grading, and are formed by expensive isostatic pressing equipment and fired at high temperatures; high-purity chromium (magnesium) corundum refractory The pouring material is made of breathable bricks and nozzle bricks, etc., the ventilation holes are made of combustible materials, and ordinary vibration dynamic molding and high temperature firing are used, so that the quality of the product can also be achieved.

3. In industrial applications, refractory castables are also very commonly used refractories. At the same time, the specifications of this material can be divided into many types, and the performance and application range of different types are different. When we choose the right product, we need to understand the product's performance and scope of application so that its products can play a better role and value.

The Technical Development of EAF Steelmaking   has a history of about 100 years. Although always facing the challenges and competition of several other steelmaking methods, especially the impact of high-efficiency oxygen converter steelmaking, the proportion of steel production in electric arc furnace steel production in the world's total steel output continues to rise year by year. Electric arc furnace steelmaking relies on graphite electrodes to generate electric arc, which converts electric energy into thermal energy in the arc light. Steelmaking method of melting furnace charge and removing impurity components such as sulfur and phosphorus, and then adding required elements (such as carbon, nickel, manganese, etc.) to smelt various steels or alloys with different properties. Furnace temperature can be accurately controlled with electric energy heating, which produces less high-temperature exhaust gas, and the thermal efficiency of electric arc steelmaking fur

Why use zircon bricks for the construction of glass kiln?

In the glass melting furnace, the molten glass liquid and the flame flying material will cause certain erosion and damage to the   zircon refractory bricks   refractory lining of the kiln, which in turn affects the service life of the glass melting furnace. In addition, it is necessary to reduce the pollution of the molten glass. From the performance indexes of representative  zircon bricks  for glass kiln at home and abroad, zircon bricks are more wear-resistant, more resistant to corrosion, and can reduce the pollution of molten glass. Zircon brick with such properties for glass kiln:  1. High refractoriness and high softening temperature.  2. anti-slag liquid erosion ability, strong acid resistance.  3. High compressive strength.  4. Good thermal shock resistance. The zircon brick is used for the working layer of the glass kiln wall, and its density is high, and it is strong against the glass liquid as the working layer of the pool wall. Therefore, the choice of  zir
