Wear-resistant ceramic material for repairing dry quenching furnace bracket support part and forming method thereof

Abstract

The invention discloses a wear-resistant ceramic material for repairing a dry quenching furnace bracket support part. The wear-resistant ceramic material for repairing the dry quenching furnace bracket support part comprises 20%-40% of fused mullite particles with the particle size ranging from 5 mm to 3 mm, 10%-25% of fused dense corundum with the particle size ranging from 8 mm to 3 mm, 5%-15% of fused alumina zirconia particles with the particle size ranging from 3 mm to 1 mm, 3%-20% of sintered alumina particles with the particle size ranging from 1 mm to 0 mm, 5%-20% of composite ceramic nano powder, 3%-15% of aluminate cement, 1%-5% of composite antiknock agents, 0.25% of composite water reducers and 4%-6% of industrial softened water, wherein the composite antiknock agents adopt two or more of water-soluble explosion-proof fibers or aluminum lactate or aluminum metal or stainless steel fibers, the water reducers adopt two or more of sodium polyphosphate or sodium tripolyphosphate or sodium hexametaphosphate or sodium humate or water glass. The wear-resistant ceramic material is used for repairing the dry quenching furnace bracket support part, the integral structure is completed after forming in conducted, abrasion loss is small, the creep value is low, very high strength and toughness are achieved, and shock resistance and abrasion resistance are better.

Description

Technical field: [0001] The invention relates to a pouring material, in particular to a ceramic wear-resistant material for repair used in the supporting part of the dry quenching coke oven bracket. Background technique: [0002] During the use of most CDQ coke oven corbel support parts, due to the complex structure and the influence of various problems, such as frequent temperature fluctuations in the chute area, continuous erosion of circulating flue gas, etc., the structure of the corbel support parts changes. Fractures occurred in the ramp area, and cracks and disconnections occurred in the brick layer from the vault along the corbel stress point. Because the corbel support part bears a large load and is not easy to replace, it is very troublesome to overhaul. The furnace needs to be shut down for more than 15 days during routine maintenance, and maintenance is required every few months, which wastes a lot of time and brings great economic losses to the production of the...
