Refractory lining dual-chute of dry quenching furnace and technique method of building thereof

Abstract

The invention discloses a technique method of building a refractory lining dual-chute of a dry quenching furnace, and belongs to the building construction field of metallurgical equipment. The technique method is mainly used for solving the problems that the construction difficulty of the refractory lining dual-chute of the dry quenching furnace is big, and the dimension accuracy is hard to control. The technique method includes the first step, selecting proper refractory bricks and pre-practicing mating objects according to equipment requirement; the second step, manufacturing standard fixtures with corresponding dimensions; the third step, confirming position of every supporting wall by a tool; the fourth step, timely detecting bias of corresponding dimension and making adjustment during the building process according to corresponding reference line. Specific to bracket brick expansion or rupture of a single-chute bracket supporting wall in the prior art, the technique method reduces the safety problem of the dry quenching production; the method applies a technique of 'pre-practicing for many times and selecting bricks to form a complete set' and a control method of 'measuring every brick while adjusting every layer', so that the supporting wall stability of a chute zone is improved, and the service life of the dry quenching furnace is prolonged.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment building construction, and more specifically relates to a dry quenching coke oven refractory lining double ramp and a process method for building the same. Background technique [0002] Coke quenching is an important link in the coke production process. There are two types: wet coke quenching and dry coke quenching. At present, most of them adopt dry coke quenching to meet the requirements of environmental protection and energy saving. A CDQ system project consists of a coke quenching oven, primary dedusting, preheating boiler, secondary dedusting and circulation fan, etc. The coke quenching oven consists of an upper cone, a pre-storage chamber (circular air duct), an inclined air duct and a cooling chamber composition. [0003] The coke dry quenching process is compared to the traditional wet coke treatment process. It uses inert gas to cool the red hot coke in the coke dry quenching oven ...

AI Technical Summary

Problems solved by technology

This scheme can control the indexing center and elevation of each partition wall, but it cannot control the size of the special refractory bricks used for masonry and the error generated during masonry, and cannot guarantee that the combined bricks at the joint can be closed smoothly. The degree of occlusion is not enough, and the stability and precision of the structure cannot be guaranteed
