Abstract

The invention discloses a regenerated pouring material used for swinging runner and prepared from waste slide plates. The pouring material comprises the following materials in parts by weight: 25-40 parts of waste slide plate particles, 15-25 parts of high-aluminum alumina, 10-20 parts of white corundum, 10-25 parts of silicon carbide, 5-10 parts of alpha-Al2O3 micro powder, 2-5 parts of zircon sand, 1-3 parts of silicon micro powder, 2-4 parts of calcium aluminate cement, 1-3 parts of metal silicon, 0.08-0.12 part of anti-explosion fibers and 0.05-0.15 part of an additive FS200. The preparation method disclosed by the invention is simple, easy to realize, capable of lowering cost of the casting material for the swinging runner by over 20%, saving excellent refractory raw material resources and effectively prolonging service life of the regenerated pouring material, and has remarkable economic and social benefits for improving environment and realizing resource recycling.

Description

technical field [0001] The invention belongs to the field of refractory castables, in particular to a regenerated castable for swing launders prepared from waste slide plates and a preparation method. technical background [0002] The swing launder is the key device for blast furnace ironmaking and iron tapping. The swing launder castable plays a very important role in the smooth operation of the blast furnace ironmaking. Use in the harshest areas. Oscillating launder castables require good erosion and erosion resistance and excellent spalling resistance. The large and medium-sized blast furnace swing launders are all made of high-quality Al 2 o 3 -SiC-C castables are generally made of high-purity fused corundum as raw material, together with silicon carbide, carbon and high-purity matrix fine powder, and adopt ultra-low cement bonding technology. Because the swing launder castable is composed of high-grade and high-quality raw materials, the cost of materials remains hi...
