Maintenance method for smoking of small oven ends of 7.63m coke oven

Abstract

The invention relates to a maintenance method for smoking of small oven ends of a 7.63m coke oven. The method is characterized by comprising the following steps that a, small protection plates of theside faces of the small furnace ends of the oven tops of the machine side and coke side are cut off and disassembled; b, the small furnace ends of the oven tops of the machine side and coke side are disassembled; c, clay bricks of the fourth to tenth layers are processed to form grouting holes; d, a fiber rope of the upper portion of an oven door frame is disassembled, air blowing is conducted forsweeping, and the ceramic fiber rope is subjected to filling; e, the small oven ends of the machine side and coke side are constructed. The maintenance method for smoking of the small oven ends of the 7.63m coke oven has the advantages that a sealing system of the oven head part of the whole coke oven is rebuilt, the measure is powerful, the operability is high, the effect is obvious, the smokingphenomenon of the small oven ends is eliminated, the production and environmental protection demands are met, the grouting material application is precise, and the cost of maintenance engineering islowered.

Description

technical field [0001] The invention relates to a method for maintaining a coke oven, in particular to a method for maintaining smoke from a small burner head of a 7.63-meter coke oven. Background technique [0002] During the perennial production process of the 7.63m coke oven, the expansion of the refractory bricks, coupled with the external force of the coke pusher and other machinery, can easily cause problems such as loosening of the small furnace head brick of the coke oven and damage to the refractory fiber rope on the upper part of the furnace door frame. The damage of these coke oven components directly leads to the decrease of the sealing performance of the furnace head of the coke oven body, and the occurrence of smoke from the small furnace head during the production process, which seriously affects the production operation and causes environmental pollution. [0003] Therefore, the small burner head of the coke oven body that emits smoke needs to be repaired urg...

Problems solved by technology

[0002] During the production process of the 7.63-meter coke oven, the expansion of the refractory bricks, coupled with the external force of the coke pusher and other machinery, can easily cause problems such as loosening of the small furnace head brick of the coke oven and damage to the refractory fiber rope on the upper part of the furnace door frame.

The damage of these coke oven components directly leads to the decline of the sealing performance of the furnace head of the coke oven body, and the occurrence of smoke from the small furnace head during the production process, which seriously affects the production operation and causes environmental pollution.

[0003] Therefore, the small furnace head of the coke oven body with smoke needs to be repaired urgently
