Low wall quick change wear-resistant prefabricated part and preparing method thereof

Abstract

The invention discloses a low wall quick change wear-resistant prefabricated part and a preparing method thereof, and belongs to the technical field of refractory materials. The wear-resistant prefabricated part is prepared from, by mass, 20-30 parts of titanium calcium aluminate aggregate, 20-30 parts of zirconium titanate aggregate, 5-10 parts of zirconium titanate calcium powder, 10-16 parts ofcalcium alumino-titanate powder, 5-9 parts of silica powder, 5-9 parts of alumina micro powder, 5-9 parts of aluminate cement, 6-10 parts of vitrified perlite, 0.15-0.18 part of sodium tripolyphosphate and 0.13-0.16 part of explosion-proof fiber, wherein sodium tripolyphosphate and the explosion-proof fiber are extra materials. The low wall quick change wear-resistant prefabricated part is used for replacing castable in the prior art and has the advantage of being convenient to construct, established cement kilns are good in thermal shock resistance and excellent in wear-resistant performance, the construction period is short, and the periodical maintenance cost is lower.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a quick-change wear-resistant prefabricated part of a low wall and a preparation method thereof. Background technique [0002] At present, many parts of the lining low wall in the building materials industry are formed by pouring castables at the construction site, and there are many operating procedures. It is necessary to complete the cylinder lining removal, anchor nail welding, formwork support, pouring, curing, demoulding and other processes. After the pouring is completed, 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 of the kiln often has defects such as low castable strength, poor wear resistance, poor thermal shock resista...

[0002] At present, many parts of the lining low wall in the building materials industry are formed by pouring castables at the construction site, and there are many operating procedures. It is necessary to complete the cylinder lining removal, anchor nail welding, formwork support, pouring, curing, demoulding and other processes. After the pouring is completed, 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 of the kiln often has defects such as low castable strength, poor wear resistance, poor thermal shock resistance, and large thermal conductivity due to factors such as construction. The outer wall of the kiln shell has high temperature, large heat loss, and short service life. Refractory lining Body replacement is more frequent, time-consuming and labor-intensive and affects production
