Converter and electric furnace gunning materials have the characteristics of high adhesion rate and good corrosion resistance at high temperature, especially in rotating furnaces.
Furnace, electric furnace later use effect is better. This product can be carried out in the furnace temperature between 300~1700C
For gunning, the amount of water added is generally about 15%, and it can also be adjusted according to the furnace temperature to achieve satisfaction
use effect. In the process of transportation and storage, attention should be paid to moisture-proof, so as not to agglomerate and affect the use effect.
The fruit has a shelf life of two months.

Converter and electric furnace gunning material construction requirements
1. Dry gunning is used, and water is added to the gun head.
2. Air pressure 5-8kg/cm, water pressure 4-5kg/cm.
3. When spraying, the distance between the gun head and the surface of the construction body should be kept 0.8-1m.
4. The thickness of one shot should not be greater than 30-50mm.
5. This material is suitable for hot repair of various converter furnace trees
The unshaped refractory material used when repairing the lining of thermal equipment by spray construction method is called refractory gunning material. It is made of a refractory set with a certain particle gradation
Acid resistant refractory gunning material is used for spraying of blast furnaces, hot blast stoves, hot blast pipes, flue protection layers, working layers, etc.
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, even all of which are composed of granules and powders, and are subject to strong ramming. Bulk materials for construction.
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.
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.
High alumina brick is one of the indispensable basic refractory materials in the upper and middle parts of blast furnace body in iron and steel industry
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.
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
