Preparation method of high-strength wear-resistant pouring material combined with ceramics

Abstract

The invention relates to a preparation method of a high-strength wear-resistant pouring material combined with ceramics. The technical scheme is as follows: firstly taking 30-70w% of fused mullite particles, 5-25w% of andalusite, 5-20w% of tabular alumina particles, 2-15w% of alumina micro-powder, 3-12w% of pure aluminate cement and 1-5w% of silicon dioxide micro-powder as raw materials, further adding 0.2-3w% of feldspar group mineral fine powder, 1-3w% of heat-resistant stainless steel fiber, 0.02-0.1w% of polypropylene fiber, 0.1-0.5w% of water reducing agent and 3-12w% of water into the raw materials, uniformly stirring, pouring, molding, curing for 24 hours at room temperature, standing for 24 hours in air, and keeping the temperature for 8-24 hours at the temperature of 110 DEG C-300 DEG C so as to get the wear-resistant pouring material combined with the ceramics. A composite material prepared according to the invention has high strength and good wear resistance, and can betteradapt to using environments with the greater temperature change range and be used as easy-to-wear parts of equipment in cement, electric power, petrochemistry, metallurgy, coal, machinery and other industries.

Description

Technical field [0001] The invention belongs to the technical field of refractory materials. In particular, it relates to a preparation method of ceramic bonded high-strength wear-resistant castable. Background technique [0002] Casting shaped refractories occupies an important proportion in the research and application of refractory materials. Mullite corundum castable is mainly made by mixing mullite particles, corundum particles, micropowder, and other additives, binders, etc. It has good wear resistance and certain thermal shock stability. It has high strength and good wear resistance under the use conditions of about 1400 ℃. It is widely used in cement, electric power, petrochemical, metallurgy, coal, machinery Parts of equipment that are easily worn out in industries. With the development of energy saving, emission reduction and low-carbon economy, we need to increase the service life of refractory materials to reduce the consumption of raw materials to meet the require...

Problems solved by technology

As the frequency of temperature changes increases, the microcracks formed in the material will expand and eventually cause the material to crack, thus limiting the service time of the material in an environment with large temperature fluctuations
