The slag line part in the slag line thickening conical spray gun used in the steelmaking industry is a low-carbon refractory material. This low-carbon refractory material is made of nano-graphite powder, asphalt, etc., which can improve the material structure and improve the Density. Nano-graphite powder is an important part of it, and nano-graphite powder also plays an important role in it. The following Furuite graphite editor introduces the important role of nano-graphite powder in low-carbon refractories:
Nano-graphite powder and asphalt itself are high temperature resistant materials. The oxides of this composite material after low-temperature oxidation form a dense protective layer on the surface of the material to reduce the penetration of oxygen into the material, and use catalytically activated resin as a binding agent to improve the antioxidant capacity of the binding system. The role of nano-graphite powder is to nano-matrix, nano-graphite powder is combined with other materials to make composite refractory material, nano-graphite powder is combined with other materials to improve the mechanical properties and high temperature resistance of materials, etc. Nano-graphite powder can also play an effective role in filling It can improve the density of the material, reduce the occurrence of pores and porosity, and improve the oxidation resistance of the material.
The low-carbon refractory material made of nano-graphite powder is an important part of the slag line thickening conical spray gun, in which the nano-graphite powder can effectively absorb the thermal stress in the process of thermal shock and obtain the nano-graphite powder nano-slag line Partial low carbon refractory material can reduce the channel of slag erosion refractory material, thereby improving the slag erosion resistance of the refractory material, prolonging the service life of the spray gun, and reducing the smelting cost.
