Description
Technical field
The present invention relates to metal smelt sheet billet continuous casting field, more particularly to a kind of device for reducing slab nose.
Background technology
Cast is a key link in steel manufacture process, is responsible for and molten steel is become the important of definite shape finished product
Task.Slab, due to its special cooling characteristics, after slab passes through withdrawal straightening machine, is transported in continuous casting production process on roll shaft
In row course of conveying, the radiating of slab plane is uneven due to above and below, it may appear that nose phenomenon.Slab nose can give continuous casting
Adversely affect, show：1st, nose is too high can cause slab can not can cause production by gas flame cuttiug region, when serious
Stop；2nd, the slab of nose, because Action of Gravity Field can be popped up, may break the equipment such as cutting gun at the end of cutting；3、
Nose can cause slab outward appearance not good enough, if nose is above standard, and product quality be influenceed, particularly in special metal material sheet material
Continuous casting steel billet production process in, occur slab nose it is even more serious, when serious, can cause production pause accident, be based on
There is provided a kind of device for reducing slab nose for the defect of technology people in existing sheet billet continuous casting.
A kind of device for reducing slab nose disclosed by the invention can effectively solve the problem that the phenomenon of continuous casting steel billet nose so that
Slab can smoothly enter next road slab cutting action, improve the product quality of sheet material.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of device for reducing continuous casting steel billet nose,
To solve, existing continuous casting steel billet slab upper and lower surface in course of conveying is uneven in temperature to cause the technical problem of slab nose.
The present invention is achieved by the following technical solutions：The invention discloses a kind of device for reducing slab nose, bag
Roll shaft, roller support and water tank are included, roll shaft is fixedly mounted on rollers, and roll shaft is arranged in the casing of water tank, water
Sparge pipe is additionally provided with case, sparge pipe is located at the sidepiece of roll shaft, and sparge pipe is parallel with roll shaft to be installed, the vertical height of sparge pipe axis
Degree, which is more than on the vertical height of roll shaft axis, sparge pipe, is further opened with 3-5 hole for water spraying, the axis of hole for water spraying and the axis of roll shaft
Vertically, water is also placed with water tank, and water surface elevation will be at least flooded at 1/3 below roll shaft, during work, in sparge pipe from
Water is sprayed water to the top of the roll shaft.
Further, according to the difference of the production requirement of slab length, the number of roll shaft is 3-6, between roll shaft mutually
It is arranged in parallel, the distance between sparge pipe and roll shaft are 3-5cm.
Further, in order to preferably realize the radiating of roll shaft so that the upper and lower surface radiating of slab is uniform, sparge pipe
Installation site is at the 1/3-2/5 of roll shaft top.
The course of work is：Slab, by the thrust of withdrawal straightening machine, is sent to roll shaft simultaneously by the slab of continuous casting after withdrawal straightening machine
Move forward, because roll shaft is contacted all the time with slab, the time one is grown, the temperature rise of roll shaft, in prolonged operation,
Cause the radiating of slab top and bottom uneven, occur as soon as slab nose phenomenon, when serious, the production thing that production can be caused to pause
Barrier, by the application of the present apparatus, one is to carry out cooling processing by tank roll shaft, and two be the water jet roll shaft by sparge pipe
Water spray, is cooled again, at this moment roll shaft water spray, and one is due to that distance between roll shaft and slab is very short, and the temperature of roll shaft is very
Height, the water being sprayed onto on roll shaft can be gasificated into vapor, risen by vapor and cooled to below slab, and two be roll shaft water spray,
Roll temperatures can be reduced, when being contacted below slab with roll shaft, also partial heat can be taken away by roll shaft, also function to slab
Below play thermolysis, reach that the radiating of slab top and bottom is uneven, efficiently solve the slab nose phenomenon of continuous casting, adopt
With this indirect cool-down method, slab can not only be made to smoothly enter down cutting action together, it is ensured that slab cutting
It is smooth, and indirect cool-down method, cooling is gently, it is ensured that the uniformity of the immanent structure of special steel material, improves sheet material
Product quality.
It is disclosed by the invention it is a kind of reduce continuous casting steel billet nose device, can roll shaft radiated in time, improve
The radiating efficiency of roll shaft so that the upper and lower surface radiating of slab is balanced, improves the quality of continuous casting steel billet, substantially increases production
Security performance, can smoothly enter down together slab cutting action.
