Vertical wedge-shaped refractory brick for rotary limestone kiln

Abstract

A vertical wedge-shaped refractory brick for a rotary limestone kiln consists of a port wedge-shaped brick body of a wedge-shaped structure, kiln body wedge-shaped brick bodies and a tail end wedge-shaped brick body and is characterized in that the port wedge-shaped brick body consists of a wedge point and a wedge bottom, one side of the port wedge-shaped brick body is a wedge-shaped end face, and steps matched with the kiln body wedge-shaped brick bodies are arranged on one side of the wedge point and the wedge bottom; each kiln body wedge-shaped brick body consists of a wedge point building block and a wedge bottom building block which form an integrated structure, and the ends of the wedge point building block and the wedge bottom building block are respectively provided with steps matched with the port wedge-shaped brick body, another kiln body wedge-shaped brick body or the tail end wedge-shaped brick body; the tail end wedge-shaped brick body consists of a wedge point stopper block and a wedge bottom stopper block, one side of the tail end wedge-shaped brick body is a wedge-shaped tail face, and steps matched with the kiln body wedge-shaped brick bodies are arranged on one side of the wedge point stopper block and the wedge bottom stopper block. The vertical wedge-shaped refractory brick has the advantages of being convenient to lay, high in construction speed and flat in butt joint face.

Description

technical field [0001] The invention relates to a vertical wedge-shaped refractory brick used for masonry lining of a calcined limestone rotary kiln, belonging to the field of refractory materials; it has the characteristics of anti-stripping, thermal shock resistance, corrosion resistance, wear resistance, convenient masonry, and good airtight performance positive effect. Background technique [0002] The working area of ​​the rotary kiln can be divided into three sections, namely drying and preheating section, calcining section and cooling section. For example: cement, refractory materials, fracturing proppant for oil wells, lime and other calcined rotary kilns. The role of the rotary kiln lining brick is to ensure that the temperature of the three working areas in the furnace has stable and reliable physical properties within the range of process requirements; for example, anti-stripping, thermal shock resistance, high-load softness, and wear resistance. In the prior ar...

AI Technical Summary

Problems solved by technology

In the prior art, the lining brick of the rotary kiln is divided into a refractory layer and an insulating layer; the existing technical defects are: the masonry process is complex, the refractory layer and the insulating layer are easy to separate during use, the refractory and insulating properties are poor, and the service life is short , the actual service life is 8-10 months

It leads to long maintenance time and high production cost, which obviously affects the economic benefits of the enterprise
