High-alumina refractory bricks are made from bauxite or kaolinitic clays. The definition high-alumina refractory bricks contain between 50 and 87.5 percent alumina. They are much harder and tougher than fireclay refractories at high temperatures and in basic environments.
Phosphate High Alumina Bricks (also called Phosphate Bonded High Alumina Bricks) are a kind of new type environmentally friendly refractory, composed of normal refractory and light weight insulation refractory to meet the daily production requirements and save costs on coal and powder of users.
High Alumina Refractory castable(also called High Alumina Castable) is made of high alumina bauxite as clinker, refractory clay as powder.
Mullite Refractory Bricks (also called mullite bricks) are made of synthetic fused mullite or sintered mullite, pressed by selected shaping processes, and fired in high temperature furnaces. Mullite refractory bricks offer high density, low porosity, good hot strength, and good slag resistance.
Andalusite bricks have high cold crushing strength, high refractoriness under load, high thermal stability, good creep resistance and thermal shock resistance. It is alternative product for high aluminum bricks, used in the professional of the key parts of the furnaces.
Chrome Corundum Refractory Brick is kind excellent high temperature material, it contains 33~90% of Al2O3 and 10~66% of Cr2O, mixed in a certain proportion, and made of special refractory production technology.

Refractory Bubble Alumina Ball (also called Refractory Hollow Alumina Ball, or Sphere Alumina Refractory), Bubble Alumina balls and likely products are light refractories with high temperature resistance and excellent energy saving, which are very stable in various atmospheres.
Calcined Kaolin Material (also called Kaolin Clay or Chamotte) is an essential industrial mineral primarily made up of the mineral kaolinite – a hydrous aluminum silicate. Kaolin can be found in applications all around us, from consumer products, to advanced industrial processing.
High Alumina Raw Materials (also called bauxite or flint clay) are used to improve the performance of refractories by imparting properties such as strength, protection from chemical and physical attack, and slag resistance.
Refractory mud, refractory cement, and refractory castables are all unshaped refractory materials and are commonly used in the refractory industry. Refractory mud is used for building refractory bricks. Refractory mud is also called refractory clay or joint material. Used as joint material for refractory masonry. Refractory cement is a material for making refractory concrete. Refractory castables are made of refractory aggregates, powders, and binders. They are also called castables because of the pouring construction. 1. Refractory Mud Refractory mud can be divided into clay, high alumina, siliceous, and magnesia refractory mud according to materials. It is composed of refractory powder, binder, and admixture. General refractory clay, which is made from refractory clinker powder and an appropriate amount of plastic clay as a binding agent and plasticizer, has low strength at room temperature and has higher strength only when it forms a ceramic bond at high temperatures. The particle size of refractory mud varies according to application requirements. Its ultimate particle size is generally less than 1mm, and some are less than 0.5mm or finer. The materials used for refractory mortar should be considered together with the materials for masonry refractory products. In addition to being used as a joint material,...
Lightweight mullite insulation bricks are a type of insulation bricks. They are insulating refractory bricks made of mullite as aggregate. Mullite insulation bricks are white and can be directly exposed to flames. They have high refractoriness and are mainly used. Used in hot blast stove tops, blast furnace shafts, and bottoms, glass melting furnace regenerators, ceramic sintering kilns, dead-end furnace linings of petroleum cracking systems, etc. Dimensions of lightweight mullite insulation bricks The dimensions of conventional lightweight mullite insulation bricks are 230 x 114 x 65mm. Lightweight mullite insulation brick model Our common models of lightweight mullite insulation bricks include JM23, JM26, JM28, and JM30. The main difference between them is the content of aluminum oxide and iron oxide. Different contents can withstand fire-resistant temperatures and thermal conductivity. The coefficients and thermal expansion rates are different. Characteristics of lightweight mullite insulation bricks 1. Low thermal conductivity and good thermal insulation effect; 2. Low thermal melt. Due to low thermal conductivity, the mullite series lightweight insulation bricks accumulate very little heat energy, and the energy-saving effect is obvious in intermittent operation; 3. Low impurity content, very low content of alkali metal and other oxides in the iron box, therefore, high refractoriness;...
A vacuum lifting package is mainly composed of a package body, package cover, lining, aluminum suction tube, ejector, boom, beam, turbine, manual transmission mechanism, inverted aluminum port gland device, etc. It is a commonly used type in the aluminum and electricity industry. Equipment, because the high-temperature liquid aluminum is shipped in the lift package, the main place where refractory castables are used is in its lining. It is necessary to build a refractory castable that can withstand high temperatures and liquid aluminum, but the pouring of vacuum lift packages How should materials be selected? First of all, because the activity of aluminum water is relatively high and has strong permeability when we choose refractory materials, we must ensure that the refractory materials have the functions of resistance to penetration, erosion resistance, impact resistance, and wear resistance. At present, the refractory materials we commonly use The material is mainly non-stick aluminum refractory materials. The non-stick aluminum castable is made of high-alumina bauxite clinker as aggregate, high-alumina bauxite clinker, magnesia mixed and co-ground as powder, and water glass as binder. It has good shock resistance, permeability resistance, and impact resistance. It is a refractory castable commonly used in the aluminum and electricity...
In the application process of refractory materials, the problem of reduced strength of refractory castables is often encountered. So, what causes the decrease in the strength of refractory castables? This article will conduct a comprehensive and detailed analysis of this and propose corresponding solutions. 1. Quality issues of refractory castables Refractory castables are mainly composed of refractory aggregates, powders, and binders. If there are quality problems with the raw materials, the hardness and strength of the refractory castables will be affected. To ensure the quality of raw materials, we can select high-quality suppliers and conduct appropriate quality testing and screening. 2. Improper construction of refractory castables Improper addition of water causes a decrease in the strength of castables: Refractory castables are usually supplied in a bag. Usually, after arriving at the site, construction workers have to add water for mixing before use. However, the amount of water added is usually very important. Excessive water addition If the amount is too small, the raw materials cannot be fully integrated. Adding too much water will cause the aggregate and powder to separate and deposit, causing the refractory cast components or linings to produce more pores due to the escape of a large...

Construction Preparation 1. Check the drawings to determine the variety, model, masonry length, progress, and various technical requirements of each part of the kiln. 2. Confirm the construction plan with the user, supplier supervisor (if necessary), and the construction party, and be responsible for explaining it to the construction personnel. 3. According to the construction sequence, anti-flaking high-alumina bricks are stored according to shape, size, material, etc. 4. Kiln inspection, determination of ring line and center line. Construction in Progress 1. Anti-flaking high-alumina bricks must be handled with care during transportation. Throwing or impact damage is strictly prohibited. 2. For wet masonry, refractory mud of the same material must be used. 3. If a bricklaying machine is used for construction, it can be operated continuously; if a cross-support or one-line support method is used, the masonry regulations must be strictly followed. 4. The mortar joints in masonry are 1~2mm....
