2000Insulating fire brick introduction:
Insulating fire brick is a new type of building material synthesized with polymer materials. The main function is to keep warm, reduce heat loss and improve thermal efficiency. It is a scientific and efficient energy-saving technology. The refractory is generally divided into two types, namely unshaped refractories and shaped refractories. Unshaped refractory materials are also called castables. Shaped refractory materials generally refer to refractory bricks. Their shapes have standard rules and can also be temporarily processed when building and cutting as needed. But there are still big differences between refractory bricks and insulation bricks:
Density: As a thermal insulation material, the general density of thermal insulation brick is about 0.8-1.0g/cm3, but the density requirement of refractory brick as a fireproof material will be higher, because the higher the density of refractory brick, the better the density and the stronger the strength. may be high. Most of the refractory bricks have a density of more than 2.0g/cm3.
Refractoriness: The performance of thermal insulation bricks is mainly in thermal insulation. Although they have a certain degree of fire resistance, they are not as good as refractory bricks in refractory performance. The fire resistance of thermal insulation bricks is generally below 1400 degrees. However, refractory bricks are different. As refractory materials, refractory bricks have their own refractoriness levels that cannot be compared with thermal insulation bricks.
Insulating fire brick characteristics:
1. Low thermal conductivity, with good thermal insulation effect;
2. Low thermal melting, due to low thermal conductivity, mullite series lightweight thermal insulation bricks accumulate little heat energy, and the energy saving effect is obvious in intermittent operation;
3. Low impurity content has a very low content of oxides such as alkali metals in iron boxes, therefore, high refractoriness; high aluminum content enables it to maintain good performance in a reducing atmosphere;
4. High thermal compressive strength;
5. The appearance size is accurate, the speed of masonry is accelerated, the use of refractory mud is reduced, and the strength and stability of the masonry are ensured, thereby prolonging the life of the lining;
6. Can be processed into special shapes. To reduce the number of bricks and joints.
Insulating fire brick application:
Can be used as hot face refractory lining or backing insulation layer of other refractory materials, used in melting furnaces, firing kilns, flues, refining devices, heating devices, regeneration devices, gas generators and pipes, soaking furnaces, annealing furnaces , reaction chambers and other similar industrial thermal equipment.

Alkali resistant castable Experiments show that the alkali pouring material has excellent alkali resistance much better than ordinary clay or high alumina pouring material. Ordinary and low-cement alkali-resistant castables have been successfully used in double-layer structural linings for preheater roofs, cones, tertiary air ducts, etc., where shaped bricks are not suitable. The low-cement alkali-resistant pouring material can also be used in the rear kiln mouth, cooler and kiln door cover. 2. High alumina and corundum castables High alumina and corundum castables for cement kilns include low cement and ultra-low cement castables, high strength corundum castables, etc. Calcined bauxite and cut jade are used as aggregates in the castable. Low cement and ultra-low cement type high alumina castables can be used in front and rear kiln mouths, chain belts, kiln door covers and cooler side walls. 3. Insulation casting section The heat-insulating castables for cement kilns include ordinary heat-insulating castables, high-strength heat-insulating castables, and ordinary and low-cement alkali-resistant heat-insulating castables. Usually high alumina cement is used as a binder in the castable. Ordinary heat-insulating castables use expanded perlite, expanded vermiculite and waste light bricks as aggregates. High-strength heat-insulating castables use refractory clay ceramsite, fly ash ceramsite, shale ceramsite, etc. as aggregates. Alkali-resistant and heat-insulating castables use alkali-resistant lightweight aggregates. Ordinary heat-insulating castables and their prefabricated blocks can be used as heat-insulating villages in double-layer structural linings of coolers, preheaters, calciners, kiln door covers and tertiary air ducts; high-strength heat-insulating castables and their prefabricated Blocks are available as single-layer linings in the neck and disintegration zones of conventional kilns. Ordinary and low-cement alkali-resistant and heat-insulating castables can be used in preheaters in small and medium-sized kilns and other parts that require alkali-resistant heat insulation. 4. Steel fiber reinforced refractory castables Adding steel fiber can improve the dismantling strength of the castable, and greatly improve the thermal shock resistance, impact resistance and wear resistance of the castable. Our company has carried out a lot of systematic research on steel fiber reinforced refractory castables, and developed a series of steel fiber reinforced refractory castables.

Corundum self flowing castable is a high-tech product developed according to the theory of solid fluid and combined with the application characteristics of refractory materials, which is the first in China. The corundum self-flowing material can be degassed and leveled without vibration with the help of its own gravity, so as to achieve densification.
Chrome corundum brick refers to corundum refractory products containing Cr2O3. At high temperature, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than that of pure corundum products. Chromium corundum products are widely used, and the content of Cr2O3 is mostly in the range of 9% to 15%.
Common low-creep high-alumina bricks can be used in blast furnace hot blast stoves, as well as other industrial kilns, and can also be made into low-creep high-alumina bricks of different sizes according to specific construction requirements, such as lattice bricks, special-shaped bricks, anchor bricks, etc. , mainly used in industrial kilns in long-term high temperature environments
