Rapid sintering gunning mix for RH and preparation method of rapid sintering gunning mix

Abstract

The invention discloses a rapid sintering gunning mix for RH, which comprises the following components: 28.0-43.0 parts by weight of fused magnesite particles with the particle size of less than 5mm and greater than or equal to 3mm; 12.0-26.0 parts by weight of fused magnesite particles having a particle size of less than 3 mm and not less than 1 mm; 10.0-18.0 parts by weight of fused magnesite particles having a particle size of less than 1 mm and greater than or equal to 0.5 mm; 8.0-13.0 parts by weight of forsterite particles having a particle size of less than 1 mm and not less than 0.5 mm; 6.0-11.0 parts by weight of fused magnesite fine powder with a particle size of less than 0.088 mm; 2.0-7.0 parts by weight of forsterite fine powder with a particle size of less than 0.088 mm; 6.0 to 10.0 parts by weight of hydratable alumina micro powder; and 1.5 to 4.0 parts by weight of silica powder. The rapid sintering gunning mix also includes binding agent accounting for 4.5-5.5 wt% of the raw materials, and the water reducing agent accounting for 1.0-1.5 wt% of the raw materials. The invention also provides a preparation method of the rapid sintering gunning mix for RH.

AI Technical Summary

Benefits of technology

The present in this patented technology provides an improved method for producing quick fired materials that are resistant against corrosion caused during use at various stages throughout production or storage processes such as steel making operations. This results from the unique properties of these materials when mixed together uniformly without any impurities like iron oxide (FeO). Additionally, it suggests that the resulting mixture should have strong bonds between particles even if they were separated beforehand due to their different melting points. Overall, this new process offers technical benefits over existing methods while reducing wear rates compared to traditional techniques used in manufacturing.

Problems solved by technology

The technical problem addressed in this patents relates to improving the lifespan of an immersion type arc furnace refinery system that uses various types of metals like iron, nickle, copper, etc., while reducing costs associated with frequent replacements due to wear out over many years.
