Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.

Castables Refractory for cement kiln Castables for cement kilns are special refractory castables for cement kilns. In my country, the new dry-process cement technology is developing rapidly, and the design and brick shape of PC and SP kilns are also very complicated. In order to adapt to this situation, our factory has developed a series of new refractory castables to replace the traditional refractory materials. Practice has proved that it is more suitable to use castables in parts with complex structure and kiln body deformation. Castables are also suitable for coolers, preheaters, precalciners, kiln door covers, tertiary air ducts and other parts that require thermal insulation. Its varieties include alkali-resistant castables, high-alumina and corundum castables, heat-insulating castables, and steel fiber reinforced refractory castables. Gongyi Yuying Refractory Co., Ltd. operates: castables for cement kilns, prefabricated blocks, low cement castables, refractory mud, refractory ramming materials, corundum castables, refractory castables, steel fiber castables, steel jade castables, Refractory plastics, high alumina castables, wear-resistant castables, plastics, castables, clay castables, refractory castables manufacturers, the company has 160 employees, including 12 senior professional and technical personnel, with an annual production capacity of 60,000 tons , has light and heavy material production lines, various production, testing and testing equipment, including 10 sets of 400-ton to 1,000-ton series forming presses, two (148 meters long and 118 meters long) high temperature tunnel kiln . Castables are also suitable for use in some parts of coolers, preheaters, precalciners, kiln door covers and tertiary phoenixes. Suitable thermal insulation castables can be used in preheaters of cement kilns and other parts that require thermal insulation. The main castables used in cement kilns are:   index Alkali resistant castable High alumina castable High Alumina Steel Fiber Castable High strength mullite castable Silicon carbide anti-skin castable GT-13NL G-16 GF-16 G-20G GC-13H Al2O3%≥ 35 65 65 65 55 SiO2+SiC%≥ - - - - 35 Bulk densityg/cm3≥ 2.10 2.5 2.5 2.60 2.5 Cold pressed strengthMpa≥ 110℃×24h 60 80 80 80 80 1100℃×3h 60 80 80 90 100 Flexural strengthMpa≥ 110℃×24h 6 8 9 8 8 1100℃×3h 6 8 9 9 10 Rate of change of line after burning 1100℃×3h ±0.5 ±0.3 ±0.3 ±0.3 ±0.3   1. 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.

Silicon carbide castables mainly use 98 silicon carbide as the main raw material, add water reducing agent and micropowder, and use pure calcium aluminate cement as binder to make amorphous refractory materials. Cupola and other high temperature materials to be recorded.

Magnesia alumina bricks use periclase as the main crystal phase and magnesia-alumina spinel as the matrix. They are better in thermal shock resistance than magnesia bricks. In order to improve the thermal shock resistance of magnesia bricks, alumina or alumina is introduced into the ingredients. Bauxite clinker fine powder to form a magnesia-alumina sharp stone matrix, thereby making magnesia-alumina bricks

The alkali-resistant brick for cement kiln has the characteristics of strong alkali erosion resistance, good thermal shock resistance and high cost performance.

silicon mullite brick is a kind of refractory brick product made of super high alumina bauxite and silicon carbide as raw materials through a special sintering process. It has the characteristics of continuously forming a protective layer and reducing ring formation, and its heat resistance is also very good. The softening temperature under load can reach 1600 ℃, and the service life is long. Mainly used in the transition zone, decomposition zone and cooler of small and medium-sized cement kilns.
