High-strength climbing type double-splint thin shell buckle lining structure

Abstract

The invention discloses a high-strength climbing type double-splint thin shell buckle lining structure and belongs to the field of large-size smelting furnaces. A lining is divided into a plurality of partitions, wherein a metal separate backing ring or a refractory concrete isolating beam fixed on a steel shell is arranged on the edge of each lining partition; the structure of each lining partition sequentially comprises a flexible isolating layer, a lightweight insulating layer and a castable working layer from the outside to the inside; each flexible isolating layer is respectively fixed with the corresponding steel shell and the corresponding lightweight insulating layer through high-strength coating layers on two sides of each flexible isolating layer; two opposite surfaces of each lightweight insulating layer and each castable working layer are rough surfaces of which the shapes are complemented, so that each lightweight insulating layer and the corresponding castable working layer form a high-strength buckling structure. According to the high-strength climbing type double-splint thin shell buckle lining structure disclosed by the invention, the integral strength of the lining is greatly improved by using a mechanical structure formed by bulking the castable working layer and the lightweight insulating layer; the surface area of the lining at the connected part of buckles is far greater than that of a fire firing surface of each castable working layer, so that the integral shock resistance of the furnace is greatly improved, and the stability of the lining is improved.

Description

technical field [0001] The invention relates to the field of large-scale smelting and chemical furnaces, in particular to a high-strength climbing type double-plywood thin-shell buckle lining structure. Background technique [0002] With the improvement of environmental protection awareness and the increasingly prominent contradiction of resource shortage, as well as the requirements of energy saving and environmental protection in the metallurgical and building materials industry, and the reduction of production and manufacturing costs, these industries generally develop intensification and large-scale development. Among them, the metallurgical Kilns are also becoming larger and larger, and need to withstand more complex and intense thermal smelting reactions. After the shape of the kiln is determined, the lining of the kiln bears all the functions of high-temperature smelting and heat energy guiding, and is the core component of the kiln. Furnace lining itself also consum...
