Abstract
A rapid slag removing method of a heating furnace is disclosed, which aims at alleviating the labor intensity, improving the working environment and improving the slag removing efficiency. In the invention, four mounting holes are respectively arranged in slag discharging furnace doors corresponding to a steel platform channel outside the four slag discharging furnace doors on each side of the heating furnace, and two slag sliding grooves communicated to the bottom of the furnace are installed on each mounting hole, namely eight slag sliding grooves are arranged; two of the slag sliding grooves can change the slag sliding direction; these two slag sliding grooves enable half of the high-temperature steel slag in the furnace to directly and alternately slide in two slag hoppers which are arranged at the new slag hoisting points on the bottom of the furnace and are arranged in parallel, the other six slag sliding grooves enable the residual steel slag to slide in a slag transporting trolley arranged on the ground of the bottom of the furnace, the residual steel slag is transported to the new slag hoisting point and fed in the slag hoppers for hoisting, the two slag hoppers are hoisted by turns to work continuously, so that the slag removing efficiency of the heating furnace is improved.
Description
Technical field
The present invention relates to a kind of method that improves heater for rolling steel scarfing cinder efficient.
Background technology
Heater for rolling steel is an equipment common in the iron and steel enterprise; General structure is that every heating furnace both sides have four little fire doors of slagging tap; Annual heating furnace maintenance is the host node project of all fronts annual overhaul project, and the time spent has often surpassed the rolling line repair time, and heating furnace scarfing cinder operation is to drop into the project that manpower is maximum, man-hour is maximum in the annual overhaul project completely; During each scarfing cinder operation in the stove slag temperature up to 600 ℃ about; Operating environment is very abominable, and each four little fire door goes out clearly the high temperature slag from both sides, heating furnace north and south, is deposited on the steel platform passage of stove both sides absolute altitude-2.2m; The overhead traveling crane of again slag of each slag point being transported to the burner place through steel platform passage hangs the slag point, and the slag bucket of packing into after concentrating hangs away.Present large-scale walking beam furnace generally all respectively is provided with four fire doors of slagging tap in its both sides, the steel platform passage of both sides is passages of maintenance scarfing cinder; The equipment hoisting hole is provided with for the handling of furnace bottom equipment.The subject matter that exists is that the steel platform passage of absolute altitude-2.2m has only 600mm wide, and four of every sides are slagged tap and a little can not be slagged tap simultaneously, otherwise passage is blocked.Hang slag point place and can only put a slag bucket, fill and to work continuously after hanging away.Therefore cause each scarfing cinder activity duration oversize.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of and can reduce labor intensity, improve operating environment, improve the quick clinker removal method of heating furnace of scarfing cinder efficient.
The present invention hangs slag point and utilizes the installation slagging tray to improve heating furnace scarfing cinder efficient through change.The concrete grammar method is:
The correspondence fire door place of slagging tap opens four installing holes (400*400mm) respectively on four slag-tap boilers steel platform passage outdoors of the every side of heating furnace, and two slagging trays that lead to furnace bottom, totally eight slagging trays are installed at each installing hole place; Two slagging trays that can change slide slag direction are wherein arranged; These two slagging trays are slipped into newly hanging in two slag buckets that slag point place is arranged side by side of furnace bottom with the cock wheel of two of furnace high-temperature slag/always stream; Other six slagging trays slip to remaining slag in the dolly of placing on furnace bottom ground of mucking haulage; Be transported to respectively again and newly hang the slag point place slag bucket of packing into and hang away; Thereby four of the every sides of realization heating furnace are slagged tap and are a little slagged tap simultaneously, and two slag buckets lift in turn works continuously, and has improved the efficient of heating furnace scarfing cinder.
Newly hang the slag point and be positioned at the corresponding furnace bottom ground, equipment hoisting hole of heating furnace, absolute altitude is-8.8m; Here and discharge two slag buckets, guarantee two slag buckets in turn lifting work continuously.The absolute altitude of the steel platform passage of the fire door correspondence of slagging tap is-2.2m.
Can change on the slide slag direction slagging tray activity-oriented chute that can change slide slag direction is installed; Two slagging trays that can change slide slag direction are located at the corresponding fire door place of slagging tap of heating furnace soaking zone; The slag temperature is the highest in the soaking zone, amount is maximum; Account for 1/2nd of high temperature slag, the slagging tray is here directly slipped into the high temperature slag in two slag buckets that furnace bottom hole for hoist place is arranged side by side in turn; Remaining slagging tray directly slips to the high temperature slag in the dolly of placing at the furnace bottom place of mucking haulage, and is transported to respectively newly to hang the slag point slag bucket of packing into and hang away.
Method of the present invention is fit to the narrower large-scale step-by-step movement heater for rolling steel of all passages of mucking haulage.Hang slag point and utilize slagging tray to improve heating furnace scarfing cinder efficient through change, alleviated labour intensity, improved operating environment.Guaranteed two slag buckets in turn lifting work continuously with 4 slag tap and a little slag tap simultaneously, improved the scarfing cinder efficient of heating furnace, realized rolling line operation in 24 hours in advance.
