Abstract
The utility model discloses drilling equipment used for changing revolving furnace bottom blowing gas-feeding bricks, and relates to auxiliary equipment used for changing revolving furnace bottom blowing gas-feeding bricks. The equipment solves the problem that the success ratio of changing the furnace bottom blowing gas-feeding bricks is low at present. The drilling equipment adopts a structure that a frame is installed on a track, a motor is installed on the frame, the motor is connected with an electrical cabinet, a water cooling system is installed on the motor, the output end of the motor is connected with a drill bit through a pipeline, and a mounting flange is installed at the tail end of the track. The equipment can be auxiliary for on-line rapidly changing revolving furnace bottom blowing gas-feeding bricks, and ensure the full process combined blowing of the revolving furnace. During the operation, the dill bit is concentric with original gas-feeding bricks, thereby ensuring that the position of the newly changed gas-feeding brick is identical with that of the original gas-feeding brick, the flow rate and the fluid state of the gas are concordant, and the smelting effect has no excursion; the water cooling system is adopted to cool down the dill bit, therefore the intensity of the diamond dill bit is ensured; and the drilling equipment can perform multi-drilling and repeated-drilling, ensure the full process combined blowing of the revolving furnace, and realize the efficient smelting and the low-loss smelting.
Description
Technical field:
The invention relates to a kind of boring apparatus that is used to change converter bottom blowing gas brick.
Technical background: the metallurgical power that the converter top and bottom complex blowing can improve in the molten bath is learned condition, quickens the metallurgical reaction process, increases the recovery rate of steel and alloy, can also improve the quality of steel, is that modern converter is made steel indispensable technology.Because the requirement of air supply brick use properties, it than other position, converter bottom magnesia carbon brick or backup lining brick use faster.And the converter brick that all the other positions also can often occur also to be in safety residual when thick and the furnace bottom air supply brick breaks down, be forced to the bottom blowing system of stopping using.The development of Technology of Slag Splashingfor Furnace Maintenance in the recent period makes stove furnace bottom air supply brick and lining brick life-span gap bigger.
The method that existing furnace bottom air supply brick is changed is to extract air supply brick with tearing the stove car open behind the air supply brick outside surface weld fixture apparatus of damage or accident, its shortcoming is that the success ratio of extracting is low, not to drag to come out exactly to extract a part, seldom can carry out the replacing of success.
Summary of the invention: the purpose of the invention provides a kind of boring apparatus that is used to change converter bottom blowing gas brick, and this equipment can assist fast online replacement converter bottom blowing gas brick, assurance converter whole process to blow again.The invention is achieved through the following technical solutions: the boring apparatus that is used to change converter bottom blowing gas brick, comprise motor, electrical control cubicles, moving switch box, track, drill bit, frame, water-cooling system, frame is installed in orbit, motor is installed on frame, motor is connected with electrical control cubicles, water-cooling system is installed on motor, and the output terminal of motor is connected with drill bit by pipeline, at the end of track mounting flange is installed.
Water-cooling system is by the water source, and water valve and pipeline are formed.
The beneficial effect of the invention: said structure is adopted in the invention, during installation, the mounting flange of boring apparatus is connected with the mounting flange that is welded on the converter bottom blowing system, this moment, drill bit and air supply brick kept essentially concentric, after starting motor, but drill bit automatic or manual in rotation orbits, the tubular diamond head can melt damage or the fault air supply brick bore down and take out of body of heater, form a boring after withdrawing from drill bit, with after the high-pressure blast cleaning boring a new gas permeable brick being installed again, just can restart converter, realize top and bottom complex blowing.Because shell bit and original air supply brick keep with one heart on the body, can guarantee that the position of new air supply brick of changing and former air supply brick is identical, the flow of gas, fluidised form unanimity guarantee the metallurgical effect non-migration; The diamond shell bit can guarantee the slyness of holing, can be very identical with the air supply brick size of new installation, and make the gap of cooperation little, can prevent that bleed-out from causing the accident; Adopting water-cooling system is the drill bit cooling, guarantees the intensity of diamond head; Boring can be repeatedly holed, be repeated in the invention, guarantees the omnidistance top and bottom complex blowing of converter, and realization is efficiently smelted, low consumption is smelted.
Description of drawings:
Fig. 1 is the structural representation that is used to change the boring apparatus of converter bottom blowing gas brick.
Embodiment:
As shown in the figure, be used to change the boring apparatus of converter bottom blowing gas brick, by motor 1, electrical control cubicles 2, moving switch box 3, track 4, drill bit 5, frame 6, water-cooling system, water-cooling system comprises water source 9, water valve 10, pipeline 7, drill bit 5 is the tubular diamond head, frame 6 is installed on the track 4, motor 1 is installed on frame 6, motor 1 is connected with electrical control cubicles 2, the pipeline 7 of water-cooling system is connected with motor 1, and the output terminal of motor 1 is connected with drill bit 5 by pipeline, at the end of track 4 mounting flange 8 is installed.
Working process: before building the converter bottom blowing system by laying bricks or stones, perforate on the furnace shell of the installation position of protection tile and bottom blowing brick outside the bottom blowing brick, and mounting flange is gone up in welding.With hanging device the invention boring apparatus is hung setting, the mounting flange of boring apparatus can cooperate with screw with the flange on the brick body, fastening back shell bit keeps concentric with the brick body, drill bit bores moving under the drive of motor, and move forward and backward along track, transition is melted decrease or the brick body of fault gets out and form circular hole.New end rifle is installed at last and is fixed, finish whole replacing programs with mounting flange.
Claims (2)
1, is used to change the boring apparatus of converter bottom blowing gas brick, it is characterized in that: comprise motor, electrical control cubicles, moving switch box, track, drill bit, frame, water-cooling system, frame is installed in orbit, motor is installed on frame, motor is connected with electrical control cubicles, water-cooling system is installed on motor, and the output terminal of motor is connected with drill bit by pipeline, at the end of track mounting flange is installed.
