Method for supporting arch tire for building overhead brick in inclined duct of dry quenching furnace

Abstract

The invention relates to a method for building a kiln lining, in particular to a method for supporting an arch tire for building an overhead brick in an inclined duct of a dry quenching furnace. The method for supporting the arch tire for building the overhead brick in the inclined duct of the dry quenching furnace comprises the following steps of: I, building partition walls in the inclined duct, and putting a device special for supporting the arch tile between adjacent partition walls; II, putting the arch tire on the device special for supporting the arch tile; and III, pre-arranging an overhead brick on the arch tire, adjusting the scale height of the arch tire, and combining the pre-arranged overhead brick with arch springing bricks at the front ends of the partition walls. The method has the beneficial effects that: 1, due to the adoption of the method, supporting of the arch tire is easy, and building of the overhead brick is easy; 2, during supporting of the arch tire, a steelpipe is not required to be taken as a bracket, so that the using amount of steel pipe is saved, and the supporting procedures of the arch tire are reduced; and 3, the device special for supporting the arch tile can be used repeatedly, so that materials are saved; and the structure of the device is small, so that construction space is saved.

Description

technical field [0001] The invention relates to a kiln inner lining masonry method, in particular to a method for supporting arch tires for brick masonry in the chute area of ​​a CDQ furnace. Background technique [0002] The CDQ furnace is a vertical tank with a circular cross-section, and its structure from top to bottom is: pre-storage section, chute area, and cooling section. The chute area is located between the pre-storage section and the cooling section. Its structure is divided into air ducts by multiple partition walls. The partition walls extend layer by layer into the furnace. Overhead bricks are built between the partition walls. Arch tire masonry should be made when the roof brick is passed. When supporting the arch tire, the arch tire wooden frame needs to be installed first. The wooden frame consists of four columns and some connecting supports, and is placed between two partition walls. The columns of the wooden frame fall on the construction platform for ma...

Problems solved by technology

However, the construction height of the construction platform is constantly changing with the construction progress, so that the height of the wooden frame cannot be predicted in advance, and the construction platform is overlapped with wooden boards, and its flatness cannot meet the direct installation of the wooden frame; when the construction platform and the supporting arch When the height of tires is relatively close, it is necessary to install steel pipes between the partition walls as brackets, which increases the amount of steel pipes and construction procedures, which is not conducive to construction
