Refractory ramming mass (refractory taphole mass) is widely used in the tapping ditch of blast furnace less than 1000m ~ 3, but there is only one tapping ditch in this kind of blast furnace, the tapping is frequent, the interval time is short, and the castable material can not be used. Therefore, Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining the tapping groove of blast furnace. The utility model is mainly used for protecting the iron outlet ditch of the blast furnace from being eroded and scoured by high-temperature hot metal and molten slag. Al2O3-SiC-C is the main material used in modern Refractory. However, according to the different construction methods, it can be divided into castable material, vibrating material, ramming material, prefabricated trough four kinds.
The refractory material for iron and slag runner of blast furnace is mainly Al2O3-SIC-C raw materials, with many varieties. However, according to the different building methods, it can be divided into four types: castable material, vibrating material, Refractory ramming mass and prefabricated tank.

1) strictly control the product quality and the purchase channel, do the laboratory analysis of each batch of raw materials (such as some important indicators: content, water content, particle size, body density and so on) , and make the record, which is convenient for the later comparative analysis and traceability. In principle, excessive moisture content of raw materials to be treated to meet the standard before use. 2) all kinds of raw materials and products should be classified and labeled to prevent mixing, but also should pay attention to waterproof moisture. 3) add resin ramming material product general storage period is 20 days, if the storage time is too long, easy hair dry, hard to ramming molding.
Construction of Refractory ramming mass (refractory taphole mass):
We carry on the onboarding training to the construction worker, asks the worker who has dug the ditch in the blast furnace before to be the construction team foreman. Under normal circumstances, ditch body lining at least 3 days before the repair and ditch cleaning, usually only a small area of repair and maintenance can be. Site construction should also pay attention to the following points.:
1) when repairing ditches and clearing ditches, only a small amount of water can be sprinkled in order to cool down. If there is molten iron ditch, with sand and molten iron slag, and then pry up, it is best not to use air blowing, otherwise molten iron will enter the non-sintered refractory.
2) when repairing the ditch and clearing the ditch, not only should the residue and iron in the ditch be cleaned, but also the severely burned tamping material be cleaned, and then be blown clean by the trachea. At the same time both sides of the ditch sand clean to avoid sand into the iron ditch ramming material.
3) the material thickness of the bottom of the main ditch body is generally 300mm-600mm. It should not be rammed after one-time feeding. It should be continuously rammed and compacted layer by layer. The material thickness of each layer is about 100mm.
4) the tamping material should be checked before use, and the products that have hardened and dried out should not be used. The slag skimmer must avoid artificial impurities into the slag skimmer.
5) after ramming, must carry on with the fire roast 5-10 minutes, causes the ramming material surface to harden.
Silicon carbide-carbonaceous cooling stave refractory ramming mass (refractory taphole mass): has the characteristic which other materials do not have. The construction is simple, the craft request is simpler than inlays the refractory brick, the price is affordable. The ramming material of various parts of a blast furnace:

Anhydrous tap hole mix for blast furnace tap hole
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
In the blast furnace smelting process, blast furnace taphole clay, as a key plastic material, plays a vital role. This article will introduce in detail the product characteristics, working principle and innovation of blast furnace taphole clay in improving furnace stability and production efficiency.
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
We specialize in producing various types of tap hole clay. Our tap hole clay protects the blast furnace hearth, increases production and saves costs! We are your best choice for tap hole clay suppliers.
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.
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
