Novel self-bonding silicon carbide gunning mix
The invention discloses a novel self-bonding silicon carbide gunning mix. The novel self-bonding silicon carbide gunning mix is made of high bauxite clinker, brown fused alumina, silicon carbide, silicon oxide, Si micro-powder, a carbon material, ultra-low calcium aluminate cement and other materials. At high temperature, fibrous SiC generated by the Si powder and the carbon material in the gunning mix in situ is inserted into a clearance of a corundum framework structure, pores are filled, a main slag penetration channel is plugged, and the slag erosion resistance is improved favorably. According to the added SiC raw material, the content of non-oxides in a material substrate is improved, and the erosion resistance of the material is further improved favorably. The novel self-bonding silicon carbide gunning mix is constructed by using a wet-type injection technology, thereby improving the construction quality and the construction efficiency. According to the novel self-bonding silicon carbide gunning mix, the slag erosion resistance and the liquid iron scouring resistance of a repaired iron runner can be improved, the iron influx is increased, the chemical erosion resistance is strong, the thermal shock stability is high, and the service life is long.
