Problems solved by technology

However, this kind of castable with brown corundum as the main component has poor thermal shock resistance, which is easy to cause thermal spalling and structural spalling, which greatly increases the frequency of repairing iron trenches and brings great hidden dangers to the stable, safe and continuous production of blast furnaces.

Abstract

The invention relates to a 1080 m<3> blast furnace main iron runner castable and belongs to the field of refractory castables. The 1080 m<3> blast furnace main iron runner castable comprises, by weight, 50-55 parts of homogenization materials, 1-8 parts of zirconium oxide hollow spheres, 3-10 parts of zirconium silicate, 10-25 parts of zinc-aluminum spinel powders, 10-15 parts of carbon compositematerials, 3-10 parts of aluminum oxide micro powders, 1-2 parts of Guangxi mud, 0.1-0.2 part of sodium tripolyphosphate, 0.05-0.2 part of metal aluminum powders and 4-10 parts of silicon dioxide solsuspension liquids. A blast furnace main iron runner prepared by the castable has the advantages of being good in thermal shock stability, anti-stripping and long in service life.

Description

technical field [0001] The present invention relates to a 1080m 3 The utility model relates to a blast furnace main iron trough castable, which belongs to the field of refractory castables. Background technique [0002] The existing main iron trough castable is ordinary Al 2 o 3 -SiC-C castables, but ordinary Al 2 o 3 -SiC-C main iron trough castables are used in blast furnaces, and the amount of one-time passing iron is 120,000 tons. With the strengthening of smelting, the demand for increasing production is becoming more and more prominent, and the requirements for the amount of iron passing through the main iron channel are becoming more and more stringent. However, due to the poor thermal shock resistance of the iron channel, it is not resistant to erosion, which leads to product peeling, which is the lifespan. The main reason for the shortness. [0003] CN102101782A discloses a castable for main iron trough, said castable is made of alumina, brown corundum, SiC, ...
