Description
Technical Field
The utility model belongs to the technical field of steel production equipment, and particularly relates to a special tool for manufacturing a temporary skimmer.
Background
The iron storage main channel plays an important role in tapping, slag discharging and slag-iron separation in the daily production of the blast furnace. The iron storage type main channel consists of a main channel, a skimmer, a small channel, a branch channel, a channel mouth, a slag discharge channel and the like. Because the iron storage main channel is formed by pouring refractory materials consisting of aluminum oxide, silicon carbide and the like, the iron storage main channel is in contact with liquid slag iron for a long time to cause erosion phenomenon, and the iron storage main channel needs to be repaired periodically and can be used after being baked. When the blast furnace is planned and overhauled and the damping down time is long, due to heat loss of the iron slag in the furnace hearth, after production is recovered and iron tapping is carried out again, the flowability of newly generated molten iron is reduced, and the slag skimmer is easy to block when the molten iron directly passes through the slag skimmer. The traditional method is that the produced slag iron is directly put into a dry slag field without being separated by a skimmer, and then flows into the skimmer for separation after the fluidity of the molten iron is improved. In order to solve the above problems, a temporary skimmer needs to be built using refractory bricks at the front end of the skimmer. And a temporary molten iron trough is built between the main trough and the molten iron trough, so that the separation of slag and iron can be realized, and molten iron can be prevented from flowing into the original skimmer. The temporary skimmer and the temporary molten iron runner need to be paved and tamped with coke powder at the bottom of the iron storage type main runner. The temporary skimmer and the temporary iron runner are used temporarily, so that the tamping equipment is not easy to purchase in order to reduce cost. Therefore, it is necessary to design a special tamping tool for manufacturing the temporary skimmer.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a special tool for manufacturing a temporary skimmer, which is used for tamping coke powder at the bottom of an iron-storage main ditch, is very practical, has a simple structure and low cost, is convenient to operate, and is easy to popularize and use on a large scale.
The technical scheme adopted by the utility model is as follows: the utility model provides a specialized tool for making interim skimmer, the specialized tool includes toper hopper and trombone slide, and the welding of trombone slide bottom has the ring in the bottom of toper hopper, the welding of its top, the aperture that has the equipartition is opened to the bottom of toper hopper, and its top is the bucket form filler opening, and the material of toper hopper and trombone slide is the aluminum alloy.

Detailed Description
Example one
Referring to fig. 1 and 2, the special tool for manufacturing the temporary skimmer comprises a conical hopper 1 and a pull pipe 3, wherein the bottom end of the pull pipe 3 is welded at the bottom of the conical hopper 1, the top end of the pull pipe is welded with a circular ring 4, small holes 2 are uniformly distributed at the bottom of the conical hopper 1, the top of the conical hopper is a hopper-shaped filling opening, and the conical hopper 1 and the pull pipe 3 are made of aluminum alloy.
During the building of the temporary skimmer and the temporary molten iron runner, coke powder is paved at the bottom of the main iron storage runner, and the special tool is used for tamping the coke powder. When the coke powder is tamped after being paved at the bottom of the iron storage type main ditch, the coke powder and cobble mixed material (the size of the cobble is larger than that of a small hole at the bottom of the tapered hopper, and the weight of the coke powder is one third of that of the cobble) is loaded into the tapered hopper, after a large rope passes through a circular ring at the top end of the pull pipe, the tapered hopper is placed on the coke powder of the iron storage type main ditch, and the length of the pull pipe is smaller than the depth of the main ditch. Two persons respectively pull the two ends of the large rope and pull the large rope forwards and backwards, the conical hopper falls down after being lifted off the ground, and the paved coke powder is tamped by inertia and gravity. In the tamping process, a small part of coke powder in the hopper can be filled into the coke powder layer for filling.
Example two
Referring to fig. 3, on the basis of the first technical solution of the embodiment, a welding fixing disk 5 is sleeved at the bottom of the pull tube 3, the outer circumferential surface of the welding fixing disk 5 is welded with the bottom surface of the conical hopper 1, and reinforcing ribs 6 are welded at the bottom of the welding fixing disk 5 and the pull tube 3; the welding fixing disc 5 and the home reinforcing ribs 6 are made of aluminum alloy. The fixed disc and the reinforcing ribs for improving the welding strength are added in the embodiment, the strength of the tamping tool is improved, the coke powder can not be added into the mixed materials in the conical hopper, and the method is suitable for only filling cobbles into the conical hopper.
