Product Description

Alumina bricks are made from bauxite of super quality, bonding chamotte and additives. The main Al203 content is 48%-99%. The advantages of high alumina bricks are high refractoriness, anti alkaline/acid erosions, good strength under high temperature and good thermal shock resistance. High alumina bricks were widely accepted in thermal equipment of metallurgy, petroleum, chemical industry, construction materials, machinery and militaries etc.

Q:High alumina brick 80 with which high aluminum cement?
Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
Q:Corundum, high alumina and fireclay refractory difference is what
In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
Q:Difference between low creep high alumina brick and ordinary high alumina brick
The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.
Q:What's the price of high alumina refractory bricks?
The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
Q:What's the difference between a well type annealing furnace and a box type annealing furnace?
RT3 series trolley type resistance furnace is a national standard energy-saving cycle type operation furnace. It has super energy-saving structure, adopts fiber structure and saves electricity 30%. Exclusive production of composite high aluminum nails group, car anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, without the basic installation, placed on the ground floor can be used. Mainly used for high chromium, high manganese steel castings, ductile iron, roller, steel ball, 45 steel, stainless steel quenching, annealing, aging, and various mechanical parts heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high temperature control accuracy, furnace temperature uniformity. 4, a high degree of automation, simple. 5, PID programming can be used to set, fully automatic operation. 6, good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electricity, ships, paper, mining, medicine, central heating and other industrial sectors. With the development of social productive forces, its application in various industries is more and more widespread. Two, pitannealingfurnace (for example: flange heat treatment furnace) use: the furnace for metal parts, such as ring of equipment heat treatment at rated temperature: the furnace is composed of furnace body and a movable furnace cover and control system.
Q:What is spalling resistant high alumina brick?
Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
Q:The difference between ordinary and diatomite brick refractory brick
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?
In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.
Q:How many cubic bricks does a high alumina brick have?
Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
