On-line slag removal device for heating furnace

Abstract

The invention discloses an on-line slag removal device for a heating furnace. The on-line slag removal device comprises a slag removal body. The two ends of the top end face of the slag removal body are provided with adjustment grooves. A lifting lug is arranged in the center of the top end face of the slag removal body. Two limiting grooves are formed in the bottom end face of the slag removal body. The two end faces of the slag removal body are provided with adjustment holes. Two symmetrical support blocks are arranged at one side of the slag removal body. According to the on-line slag removal device, by means of the slag removal body, accumulated slag falling inside the heating furnace can be removed under the circumstance that the heating furnace is not halted; the problem that the slag which is accumulated for a long time affects the heating effect of steel billets and use of a heating furnace body is prevented; by means of the lifting lug, workers can hoist the on-line slag removal device through an overhead travelling crane in a workshop, and the on-line slag removal device is convenient to use; and by means of the adjustment grooves and the adjustment holes, when the slag removal body is hoisted, the workers can insert hooks or adjustment hooks into the adjustment grooves or the adjustment holes for adjust the slag removal body to put the slag removal body rightly on aslide way.

Description

technical field [0001] The invention relates to the technical field of a cleaning device for a steel rolling heating furnace and its application, in particular to an online slag cleaning device for a heating furnace. Background technique [0002] For the continuous hot rolling heating furnace, if the slag accumulates to a certain extent, the normal production cannot continue, and the production can only be stopped, the furnace is stopped, cooled to normal temperature, and the slag is chiseled off manually with a hammer. This kind of furnace repair generally requires the heating furnace to stop working for about 15 days, which has a great impact on continuous production and reduces production efficiency. And the existing technology is to drop into the slagging agent in the heating furnace, or install the slagging equipment at the front end of the hydraulic propulsion device of the heating furnace, or install the slagging equipment inside the equipment, the input of the slaggi...

Problems solved by technology

This kind of furnace repair generally requires the heating furnace to stop working for about 15 days, which has a great impact on continuous production and reduces production efficiency.

And the existing technology is to drop into the slagging agent in the heating furnace, or install the slagging equipment at the front end of the hydraulic propulsion device of the heating furnace, or install the slagging equipment inside the equipment, the input of the slagging agent is inconvenient, and because The temperature of the heating furnace is as high as 1300°C. Whether the input slag agent can reach the designated position and then reflect with the slag accumulation cannot be accurately confirmed; and the length of the slag removal equipment installed at the front end of the hydraulic propulsion device is limited, so the hydraulic propulsion device cannot guarantee The slag cleaning equipment can clean up all the slag accumulated in the heating furnace; the temperature in the heating furnace is as high as 1300 ° C, and the slag cleaning device installed in the heating furnace cannot guarantee continuous work after being exposed to high temperature for a long time. The above methods Both have disadvantages and deficiencies
