Abstract

The invention discloses a novel main iron runner casting material which is prepared from alumina, corundum, SiC, SiO2 micropowder, alpha-Al2O3 micropowder, modified nano carbon powder, explosion-proof fiber, metallic silicon powder, calcium aluminate cement and sodium tripolyphosphate. According to the invention, since the modified nano carbon powder, of which the activity is much higher than that of asphalt carbon residues, is substituted for the asphalt, so the oxidation resistance effect is better. In addition, the modified nano carbon powder used as a substitute for asphalt can improve the bursting resistance of the product in the baking process.

Description

technical field [0001] The invention relates to a refractory pouring material. Background technique [0002] Asphalt is generally added to the existing main iron trench castables, which has the following disadvantages: [0003] 1. Poor environmental protection when baking [0004] Asphalt is the residue of coal tar or petroleum distillation or treatment and cracking to extract various fractions with different boiling points. The composition and properties vary with the type of raw material, distillation method and processing method. It is mainly composed of aromatic and aliphatic structures. The formed mixture is viscous liquid, semi-solid or solid, black and shiny, smelly, insoluble in water, flammable and poisonous when melted. Therefore, although adding asphalt to the iron trench material can indeed play a role in high temperature resistance, anti-oxidation, and anti-erosion capabilities, but the baking process, especially the hot repair process, releases toxic smoke, w...
