Device and method for correcting coke oven door knife edge

Abstract

The invention discloses a device and a method for correcting a coke oven door knife edge. The device is characterized by comprising a mouth-shaped square steel frame, a 5t jack, two 1t jacks and a correcting rotary rack, wherein the mouth-shaped square steel frame consists of an upper beam, two side beams, a lower beam and two hanging hooks; the tops of the two side beams are fixedly welded and connected with the upper beam, and the bottoms of the two side beams are welded with an elliptic hole respectively; two ends of the lower beam pass through the elliptic holes; one end of each of the two hanging hooks is welded with an elliptic hole, the two hanging hooks can be movably hung on the middle part of the lower beam through the elliptic holes, the other ends of the two hanging hooks are provided with an iron hook respectively, and the hook inlets of the two iron hooks are arranged in opposite directions; the 5t jack can be arranged at the bottom of the upper beam, and the bottoms of the 1t jacks can be propped against the oven door knife edge; and one end of the correcting rotary rack can be arranged below the 5t jack, and the other end of the correcting rotary rack can be arranged above the 1t jack.

Description

technical field [0001] The invention relates to a coke oven, in particular to a device and method for correcting the knife edge of a coke oven door. Background technique [0002] The coke oven door is a very important furnace protection equipment for the coke oven. The furnace door of the coke oven generally adopts the iron-to-iron self-sealing type, that is, the knife edge of the furnace door is closely matched with the knife cover of the furnace door frame, and the coke oven body is sealed. The tightness of the furnace door is closely related to the prevention of smoke and fire and the deformation and failure of the furnace frame and furnace column. Whether the knife edge of the furnace door is in good condition has a lot to do with preventing smoke and fire. During the production process, when the furnace door is removed, because the residues such as tar residue and coke powder on the knife edge and the furnace door frame knife cover are not removed in time, these resid...

AI Technical Summary

Problems solved by technology

The main material of the knife edge of the coke oven door is vermicular graphite cast iron, which has high strength and is difficult to repair and correct by hammering, and the labor intensity of the operators at the furnace door repair station is high

[0003] Therefore, there are above-mentioned inconveniences and problems in the correcting device and method of the known coke oven door knife.
