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.

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.
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.
The alumina ball is also called the high aluminum accumulation of heat ball.High alumina refractory ball is based on bauxite as the mainly raw refractory material.Adding powder and additives and anchoring agent.After proportioning, molding and high sintering to make it.The production engineering of high alumina refractory ball is similar to that of high alumina refractory brick.It should be based on the properties of raw materials,high alumina refractory ball requires production conditions and other factors to determine.
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
Anhydrous tap hole mix for blast furnace tap hole
High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug,such as nozzle brick.
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.
