Abstract
The utility model relates to a casting blank flame cleaning gun which comprises a handle, an oxygen pipe, a gas pipe and an adjusting valve, wherein the front parts of the oxygen pipe and the gas pipe are bended upwards at 18-23 degrees; at least two gun nozzles are vertically connected with bending sections; and the distance which is 2.5 times longer than the width of a flame cleaning trace is left between centre lines of the two adjacent gun nozzles. Therefore, the verticality between the gun nozzles and the surface of a casting blank can be ensured to be unified, the body is upright when cleaning, the cleaning operation is conveniently carried out, the cleaning time is shortened, the cleaning efficiency is increased by more than twice, the revolution of the casting blank is accelerated, the pressure for a blank field storeroom is relieved, the production is ensured to be carried out smoothly, and the contract is guaranteed to be realized on time.
Description
Technical field
The utility model belongs to the continuous casting field of tool, relates in particular to a kind of scafing rifle that the continuous casting billet blemish is handled that is used for.
Background technology
Conticaster is when production Ultra-low carbon class steel grade, because the subcutaneous surface defects such as pin hole, bubble that exist of strand, make strand in the rolling particularly cold-rolled process in rear portion, surface defect can come out at surface of steel plate, thereby cause the steel plate degradation, when serious even to cause coiled sheet to declare useless, form quality accident, bring serious economy loss to producer.For this reason, each steel mill all must be to casting billet surface and that processing that strips off the skin of driving in the wrong direction, and the mode that promptly adopts scafing so that surface defect is disposed, guarantees to roll the surface quality of back coiled sheet with casting billet surface cleaning 3～5mm.But because oxygen hose and the gas pipe of handling used scafing rifle that strip off the skin at present all adopts straight-bar type, fettler needs long-time stoop labor, and is tired easily; Especially this scafing rifle quantity is single, causes cleaning efficiency lower, is difficult to satisfy to produce needs, has not only increased the warehousing pressure in storehouse, base field, has prolonged the turnaround time of strand, and has caused strand to deliver goods on schedule, the carrying out smoothly of influence of rolled production.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple and practical, small investment, instant effect, the strand scafing rifle that cleaning efficiency is high.
For this reason, the solution taked of the utility model is:
A kind of strand scafing rifle comprises handle, oxygen hose, gas pipe and control valve, and the front portion of described oxygen hose and gas pipe all upwards bends certain angle, is connected at least two rifle mouths with bending segment is vertical.
Distance between adjacent two rifle mouth center lines determines according to casting billet surface scafing trace width, and is 2.5 times of scafing trace width.The anterior upwards angle of bending of oxygen hose and gas pipe is 18 °～23 °.
The beneficial effects of the utility model are:
Because the front portion of oxygen hose and gas pipe is all upwards bent certain angle, the rifle mouth can be unified with the casting billet surface perpendicularity, body erect when guaranteeing the fettler operation, be convenient to prune job, and this angle makes the flame of injection help the casting billet surface processing that strips off the skin, thereby shorten clearance time, improve cleaning speed more than one times, accelerate the strand turnover, alleviate the pressure in storehouse, base field, guarantee the direct motion of production and on time cashing of contract.
Description of drawings
Accompanying drawing is a strand scafing rifle structural representation.
Among the figure: handle 1, control valve 2, oxygen hose 3, gas pipe 4, rifle mouth 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as seen, the utility model is identical with the composition of common scafing rifle, comprise handle 1, control valve 2, oxygen hose 3, different is for gas pipe 4 and rifle mouth 5., the utility model all upwards bends out certain angle with the front portion of oxygen hose 3 and gas pipe 4, be that bending segment becomes 20 ° angle with the oxygen hose 3 that the rear portion be arranged in parallel with the center line of gas pipe 4. simultaneously, be provided with two rifle mouths 5 at bending segment, two rifle mouths 5 are taked one in front and one in back to be provided with, and two rifle mouths 5 are welded on the termination and the middle part of bending segment respectively perpendicular to bending segment. the distance between two rifle mouth 5 center lines that front and back are provided with is determined according to casting billet surface scafing trace width, and be 2.5 times of scafing trace width. according to measured result, the scafing trace width average out to 8mm that the scafing rifle stayed at casting billet surface when strand stripped off the skin is so the distance between two rifle mouth 5 center lines that the utility model is chosen is 20mm.
Claims (3)
1. a strand scafing rifle comprises handle and control valve, it is characterized in that, the oxygen hose of described scafing rifle and the front portion of gas pipe all upwards bend certain angle, is connected at least two rifle mouths with bending segment is vertical.
2. strand scafing rifle according to claim 1 is characterized in that, the anterior upwards angle of bending of oxygen hose and gas pipe is 18 °～23 °.
3. strand scafing rifle according to claim 1 is characterized in that, the distance between adjacent two rifle mouth center lines determines according to the width of casting billet surface scafing vestige, and is 2.5 times of scafing trace width.
