Description
Technical field
This utility model relates to the secondary descaling steel device in a kind of special steel bar and wire production, belongs to steel rolling scale removal equipment technical field.
Background technology
In the operation of rolling of special steel bar and wire rod, high temperature (1000 DEG C) billet surface after heating can form iron scale (iron sheet), through high-pressure water descaling, iron sheet is removed after totally, is admitted to milling train and rolls.The rolling time of one steel billet is typically between the 50-120 second, and in the process, billet surface can form secondary oxidation iron sheet one layer thin compared with iron sheet again.After entering roll, this layer of iron scale major part is crushed by roll and comes off, but rolled piece surface still can remain a part of iron sheet, follow-up rolling may be pressed into surface, the iron scale forming product surface is mingled with, scabs or pit, causes billet surface mass defect, and what have can not detect in time and mail to user, cause that the product that user manufactures is done over again, even scrapped, bring about great losses.
In order to meet user's strict demand to special steel surface quality, it is necessary to the secondary oxidation iron sheet that steel billet is formed in the operation of rolling is removed clean, it is ensured that the final surface quality of steel.Current way has two kinds, one is reuse small flow high pressure water to carry out de-scaling, two is use compression air to carry out de-scaling, but two kinds of methods are respectively arranged with pluses and minuses, high-pressure water descaling has steam expansion can crush iron sheet, impact the advantage of great efforts, and scale removal effect is good, but the temperature of rolled piece can be reduced, affect the final performance of steel product, rolled piece face crack even occurs, particularly that heavy alloyed special steel Influence of production is serious；Compression air de-scaling has and causes the advantage that rolled piece temperature drop is little, but because impulsive force is little, scale removal effect is poor.
Utility model content
Technical problem to be solved in the utility model is to provide the secondary descaling steel device in a kind of special steel Rolling Production, this descaling device can Bound moisture de-scaling and compression air de-scaling respective advantage, both rolled piece temperature drop can have been reduced, do not affect properties of product, de-scaling requirement can be met again, be particularly suitable for the special steel bar that temperature drop is sensitive or wire production.
The technical scheme solving above-mentioned technical problem is:
A kind of secondary descaling steel device in special steel Rolling Production, it includes water spray ring and air spray ring, the Guan Bi ring of the annular that water spray ring and air spray ring respectively metal tube are made, water spray ring is identical with air spray ring profile, after water spray ring and air spray ring close parallel are arranged on the first milling train of bar or wire rod production line, water spray ring is vertical with the traffic direction of rolled piece with the planar annular of air spray ring, the annular space that rolled piece surrounds from water spray ring and air spray ring passes through, water spray ring and air spray ring there are (operating) water nozzle and air nozzle respectively, (operating) water nozzle is relative with rolled piece with the spout of air nozzle, water spray ring is connected with water pipe and compressed air line respectively with air spray ring.
Secondary descaling steel device in above-mentioned special steel Rolling Production, the shape of rolling piece that the shape of described water spray ring and air spray ring exports with first milling train matches, the four direction up and down of water spray ring and air spray ring has the nozzle of more than 2 respectively, the water spraying direction of (operating) water nozzle and the angle of rolling direction are 75 degree, and the jet direction of air nozzle and the angle of rolling direction are 60 degree.
Secondary descaling steel device in above-mentioned special steel Rolling Production, is separately installed with adjustment valve in the water pipe of described water spray ring and the connection of air spray ring and compressed air line.
The beneficial effects of the utility model are:
After water spray ring of the present utility model and air spray ring are arranged in the first milling train of bar or wire rod production line, utilize the advantage that roll has crushed iron sheet, the respective advantage of Bound moisture de-scaling and compression air de-scaling carries out secondary descaling steel operation, in de-scaling process, current mix with compression air stream, it is ejected into rolled piece surface against rolling direction by certain angle, both rolled piece temperature drop can have been reduced, without influence on properties of product, de-scaling requirement can be met again, be particularly suitable for the special steel bar that temperature drop is sensitive or wire production.This utility model simple in construction, easy to use, scale removal effect is good, it is ensured that special steel steel product quality, meets the requirement of user, improves the economic benefit of enterprise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A sectional view of Fig. 1.
In figure, labelling is as follows: rolled piece 1, water spray ring 2, air spray ring 3, (operating) water nozzle 4, air nozzle 5.
Detailed description of the invention
This utility model is made up of water spray ring 2, air spray ring 3, (operating) water nozzle 4, air nozzle 5.
Showing in figure, the Guan Bi ring of the annular that water spray ring 2 and air spray ring 3 respectively metal tube are made, the shape of rolling piece that the shape of water spray ring 2 and air spray ring 3 exports with first milling train matches, and water spray ring 2 is identical with air spray ring 3 profile.Water spray ring 2 and the air spray ring 3 of the embodiment shown in figure are rectangle.
Figure shows, after water spray ring 2 and air spray ring 3 are installed in parallel in the first milling train of bar or wire rod production line, the iron sheet not completely fallen off can be removed totally further, prevent the iron sheet not fallen off in the follow-up operation of rolling, it is pressed into rolled piece surface and forms product surface quality defect, affect the use of user.Water spray ring 2 and air spray ring 3 in close proximity to, it is therefore an objective to enable the current of injection and air stream to be mutually mixed.Water spray ring 2 is vertical with the traffic direction of rolled piece 1 with the planar annular of air spray ring 3, and the annular space that rolled piece 1 surrounds from water spray ring 2 and air spray ring 3 passes through.
