Problems solved by technology

[0002] At present, many parts of the lining wall in the building materials industry are formed by pouring materials at the construction site. After the completion, it needs to be cured and baked before it can be put into use. Generally speaking, the amount of water added to the on-site pouring is random, the pouring quality is not easy to control, the construction labor intensity is also high, and the construct

Abstract

The invention discloses a high-strength and high-wearability prefabricated part and a preparation method thereof and belongs to the technical field of refractory materials. The high-strength and high-wearability prefabricated part comprises the following components in part by mass: 20-30 parts of calcium titanate aggregates, 20-30 parts of calcium zirconium titanate, 5-10 parts of magnesium titanate powder, 10-16 parts of calcium titanium aluminate powder, 5-9 parts of silicon micro powder, 5-9 parts of alumina micro powder, 5-9 parts of aluminate cement, 6-10 parts of vitrified perlite; an admixture comprises 0.15-0.18 part of sodium tripolyphosphate and 0.13-0.16 part of explosion-proof fibers. The high-strength and high-wearability prefabricated part is used for replacing a casting material in the prior art and has the characteristic of being convenient to construct, and a built cement kiln is good in thermal shock resistance, excellent in wear resistance, short in construction period and relatively low in cycle maintenance cost.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a high-strength wear-resistant prefabricated part and a preparation method thereof. Background technique [0002] At present, many parts of the lining wall in the building materials industry are formed by pouring materials at the construction site. After the completion, it needs to be cured and baked before it can be put into use. Generally speaking, the amount of water added to the on-site pouring is random, the pouring quality is not easy to control, the construction labor intensity is also high, and the construction period is long. The kiln lining often has defects such as low castable strength, poor wear resistance, poor thermal shock resistance, and large thermal conductivity due to construction and other factors. The outer wall of the kiln shell has high temperature, large heat loss, and short service life. The refractory lining Replacement is more frequent, t...
