Problems solved by technology

However, repairing by means of patching can only block one end of the leakage hole, but cannot completely block the leakage hole; The serial leakage hole reappears and needs to be filled again
[0006] Repeatedly repairing the leakage hole of the coke oven not only requires a large workload and wastes manpower and material resources, but also after repeated repairing and repeated leakage, the gap at the leakage hole will gradually increase

Abstract

The invention discloses a coke oven body mending process which comprises the following steps: puncturing, namely, drilling a grout hole which is communicated with a brick work joint at the brick work joint position; and jetting, namely, jetting refractory mortar into the grout hole through using a shotcreting machine. According to the invention, in the coke oven body mending process, the brick work joint which generates a string-leakage hole source is opened through the puncturing step so that the refractory mortar can be directly jetted in the brick work joint, and the mended coke oven can not be mended again within a long time, thereby greatly reducing the mending time of the coke oven body. Thus, the coke oven body mending process provided by the invention has good mending effect and is capable of reducing the manpower and material resources for mending.

Description

technical field [0001] The invention relates to the technical field of maintenance of metallurgical mechanical equipment, in particular to a coke oven body repair process. Background technique [0002] Coke oven: A furnace usually made of refractory bricks and refractory blocks. It is a horizontal chamber coke oven whose main purpose is to produce metallurgical coke and can recover coking chemical products. It consists of a furnace body and auxiliary equipment. The coke oven body is composed of furnace roof, combustion chamber, carbonization chamber, chute area, regenerator and other parts, and is connected by flue and chimney. The whole coke oven is built on a concrete foundation. [0003] Raw coal gas: the unpurified gas product precipitated in the process of coal dry distillation; raw coal gas is a yellowish-brown vapor-gas mixture with a strong pungent odor; combustible components in coke oven gas account for about 95% and the calorific value is as high as 17MJ / m3 , so ...
