Ramming material for blast furnace
The refractory ramming material is prepared from a high proportion of granular and powdery materials and a very low proportion of binders and other components, and even all of them are composed of granules and powders. Bulk materials for construction.
Because the material is mainly used for the direct contact with the molten material, it is required that the granular and powdery materials must have high volume stability, compactness and corrosion resistance, and the induction furnace should also have insulation.
Compared with other unshaped refractories of the same material, the ramming material is dry or semi-dry and loose, and a dense structure is obtained by strong ramming. Only when heated to a sintering degree, the combined body material has strength.
After the ramming material is formed, different heating methods can be adopted to promote its hardening or sintering according to the hardening characteristics of the mixture. If it contains inorganic chemical binder, it will harden on its own.
It can be demolded and baked after having a considerable strength; if it contains a thermoplastic carbon mixture, it will be demolded after cooling to have a considerable strength, and it should be heated quickly before use to make it coking; and it does not contain a binder that hardens at room temperature, often after tamping. Sintered with die row.

The use and characteristics of ramming material:
For small blast furnace tapping system with only single tap hole or local emergency repair of large and medium blast furnace tapping system, the ramming materials listed in the above table can be used.
Among them: GT-3 is a non-baking ramming material, which adopts a new type of combination system, which does not generate water vapor during the use process, so that the iron can be directly tapped after ramming construction without any test. Thereby improving the operation of the equipment; the purpose of efficiency.
It can be widely used in the main ditch of the tap ditch of medium and small blast furnaces and all parts of the tap ditch that need to be fast.

Insulating high alumina refractory bricks mainly refer to refractory products with an aluminum content of more than 48%. They are also called lightweight high-alumina bricks or heat-insulating high-alumina bricks due to their advantages of low bulk density, light weight, and good heat insulation effect. . It is a kind of thermal insulation refractory brick commonly used in high temperature industrial kilns and thermal equipment.
The heavy parts of the chrome-zirconium mullite composite bricks are made of high-purity sintered mullite, high-purity chromium oxide, high-purity zirconia, and Guangbai mud as the main raw materials, and the light part of the raw materials are made of 47 mullite, kyanite, Bleaching beads, coke gemstones and Guangxi white mud are the main raw materials
Acid resistant refractory gunning material is used for spraying of blast furnaces, hot blast stoves, hot blast pipes, flue protection layers, working layers, etc.
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.
Fireclay bricksis suitable for supporting hot blast stoves of large, medium and small blast furnaces
In recent years, bauxite powder and bauxite have been widely used in common cast steel coatings and cast iron coatings due to their high fire resistance, good chemical stability, small expansion coefficient, rich source and low price.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
