Technical field
The utility model relates to a kind of blow device, relates in particular to a kind of frame foreign matter blow device.
Background technology
In the process of slab, slab has produced a large amount of iron scales after being heated to the high temperature about 1200 degree, and thickness reaches 1-2mm, is wrapped on six faces of slab.Slab by the mill milling process in, a large amount of iron scale produces distortion and loose or dislocation is deposited on milling train gateway foreplate and the water discharging board, thereby can cause rolling slab following table to produce scuffing or iron sheet is pressed into problems such as defective.For cleaning in time is deposited in the iron scale on foreplate and the water discharging board, the milling train designer has installed blow device in frame.
Fig. 1 has shown the structure of the blow device in the present rolling-mill housing.Blow device is arranged in mill housing 1 inboard in the frame, and it comprises nozzle 3 and corresponding water pipe 2, and nozzle 3 is connected with water pipe 2.If the injection direction of nozzle 3 is set to be parallel to the direction of roll 6, purges water so and can't purge and drop on iron scale on the water discharging board 5; If the injection direction of nozzle 3 is adjusted into the direction with roll 6 obliques; Iron scale can be piled up earlier at the two ends of foreplate 4 and water discharging board 5 so; Stopped purging water after the slab compacting that the iron sheet of piling up is rolled; And then cause having piled with iron scale on foreplate 4 and the water discharging board 5, have at last regularly shut down carry out the labor cleaning.
This shows that the blow device in the present rolling-mill housing can't be removed the impurity in the rolling-mill housing fully, thereby causes rolling slab defective to occur, even need regularly to shut down to carry out the labor cleaning, reduced production efficiency.
Summary of the invention
The purpose of the utility model provides a kind of rolling-mill housing foreign matter blow device, and this blow device can be removed the impurity in the rolling-mill housing fully, thereby eliminates slab in the operation of rolling, the defective that is caused by impurity; Simultaneously, adopt the described rolling-mill housing foreign matter of the utility model blow device can also solve milling train and need regularly to shut down the problem of carrying out the labor cleaning.
According to the foregoing invention purpose, the utility model provides a kind of rolling-mill housing foreign matter blow device, it comprises: two first nozzles, its mill housing that is separately positioned on the rolling mill roll both sides is inboard, and two foreplate settings of corresponding said milling train; In addition, said rolling-mill housing foreign matter blow device also comprises: the outer blow device of a frame, and it is fixedly installed on the roll chock in the said mill housing outside; The outer blow device of said frame comprises:
Two second nozzles, two water discharging board settings of its corresponding said milling train;
One threeway, it is connected with the conducting of said two nozzles difference;
One joint, it is connected with said threeway conducting.
The described rolling-mill housing foreign matter of the utility model blow device is divided into two parts: a part is blow device (i.e. first nozzle) in the frame; Another part is the outer blow device of frame.During foreign matter, the blow device in the frame can purge the foreign matter that is deposited on the foreplate clean in purging frame; The outer blow device of frame can purge the foreign matter that is deposited on the water discharging board clean.
Preferably, said first nozzle and second nozzle are the adjustable nozzle of injection direction.
In the above-mentioned rolling-mill housing foreign matter blow device, the angle of scattering of said first nozzle is 50 degree, and the angle of scattering of said second nozzle is 60 degree.
Through adjusting the angle of each nozzle, it is a certain amount of overlapping that the purging water of said first nozzle and said second nozzle is formed in frame, thereby can eliminate the blind area that exists in the purge.
Preferably, the outer blow device of said frame is arranged on the said roll chock through a support.
The outer blow device of said frame is installed on the roll chock, can not influence the replacing of roll, during roll change, need not dismounting.
The described rolling-mill housing foreign matter of the utility model blow device than existing blow device, can be removed the impurity in the rolling-mill housing fully, has eliminated slab in the operation of rolling, the defective that causes by impurity, and then improved the quality of slab.Simultaneously, having solved owing to the impurity problem of piling up causes needs regularly to shut down to carry out labor cleaning's problem, thereby has improved production efficiency.

The specific embodiment
To combine Figure of description and concrete embodiment that the described rolling-mill housing foreign matter of the utility model blow device is done further detailed description below.
Fig. 2 has shown the structure of the outer blow device of the described rolling-mill housing foreign matter of the utility model blow device frame in the present embodiment.As shown in Figure 2, the outer blow device of frame comprises a threeway 82, and an one of which port is connected with snap joint 81 through one section water pipe 83, and two other port of threeway 82 is connected with two second nozzles 84 through water pipe 83 respectively.
Fig. 3 is the described rolling-mill housing foreign matter of the utility model blow device structure and a user mode sketch map in the present embodiment.Fig. 4 is the vertical view of Fig. 3.Like Fig. 3, shown in Figure 4, blow device comprises that two first nozzles 3 are separately positioned on the inboard of rolling mill roll 6 one side mill housings 1 in the frame in the present embodiment, and it is respectively through water pipe 2 connection water sources.The outer blow device 8 of frame is fixedly mounted on the support 9, support 9 through screw be fixed on frame on the roll chock 7 in mill housing 1 outside of blow device homonymy, thereby can not have influence on the roll change operation.After roll 6 was pushed into frame, the staff was connected the snap joint on the outer blow device 8 of snap joint on the flexible pipe 10 and frame.When needing roll change, the staff only needs the snap joint on the blow device 8 outside frame of the snap joint on the flexible pipe 10 is pulled down, and can carry out the roll change operation.Two first nozzles 3 of mill housing 1 inboard, two foreplates 4 of corresponding milling train respectively are provided with, and its injection direction is parallel to roll 6; Two second nozzles on the outer blow device 8 of frame, two water discharging boards 5 of corresponding milling train respectively are provided with, and injection direction is parallel to roll 6.
Please continue to consult Fig. 3, Fig. 4; Rolling-mill housing foreign matter blow device in the present embodiment comprises two parts; A part is blow device in the frame that is arranged on mill housing 1 inboard; It mainly acts on is the purging through the injection water that is parallel to roll 6, purges the iron scale that is deposited on the foreplate 4 clean; Another part is the outer blow device 8 of frame that is installed on the roll chock in mill housing 1 outside, and it mainly acts on is the purging through the injection water that is parallel to roll 6, purges the iron scale that is deposited on the water discharging board 5 clean.The angle of scattering of first nozzle 3 is 50 degree, and the angle of scattering of second nozzle is at 60 degree; First nozzle 3 and second nozzle can freely be adjusted angle in the process that purges, and through adjusting the angle of each nozzle, it is a certain amount of overlapping that this two-part purging water is formed in frame, thereby eliminated the blind area that exists in the purge.The temperature of slab when not influencing operation, can control the injection sequential that purges water: slab when rolling, purge water and does not spray in frame; After slab left frame, two-part water sprayed simultaneously, continued to close automatically after 1 minute.
Be noted that above enumerate be merely specific embodiment of the present invention, obviously the invention is not restricted to above embodiment, many similar variations are arranged thereupon.If those skilled in the art all should belong to protection scope of the present invention from all distortion that content disclosed by the invention directly derives or associates.
