Abstract

The utility model provides a descaling and dust-removing apparatus of steel billets. The descaling and dust-removing apparatus of the steel billets comprises a ground-roller installed on a steel billet outlet, a cover-plate installed on the ground-roller, a discharging-residue groove formed on the upper end of the cover-plate, and a protecting-plate. The descaling and dust-removing apparatus of the steel billets is characterized in that the protecting plate is provide with connecting plates, the connecting plates are provided with effusing pipes, wherein effusing pipes are connected with a water-supply pipe, and supporting plates are installed on the protecting plate and beside the effusing pipes. The supporting plates are connected with two screw rods movably. The lower ends of the two screw rods are connected with rails, wherein two lifting hooks are sleeved on the rails. The two lifting hooks are hooked and hung with a scumming plate movably, wherein the scumming plate is provided with teeth. Utilizing the descaling and dust-removing apparatus of the steel billets, mill scales just formed can be cooled to shrink when the steel billets come out and the mill scales can be exfoliated easily through the scumming plate. Meanwhile, dusts can be restrained when cooling water are effused. The descaling and dust-removing apparatus of the steel billets has the advantages of being simple in structure and low in cost.

Description

A kind of descaling of steel stock dust arrester
Technical field
The utility model relates to a kind of de-scaling dust arrester, and particularly a kind of descaling of steel stock dust arrester belongs to steel smelting equipment design and manufacturing technology field.
Background technology
Usually smelt good steel band when coming out of the stove, its surface can be oxidized under the condition of high temperature, thereby form the iron oxide cortex of one deck densification.If before rolled steel strip, can not remove this iron scale, then in the operation of rolling, can make iron scale be rolled into steel strip surface, and affect the quality of steel band.Simultaneously, residual iron scale also can accelerate the wearing and tearing of roll, reduces the service life of roll, increases the Dust Capacity in the operation of rolling, affects working environment.The method of removing the steel strip surface iron scale in the prior art is to adopt the high pressure water impact steel strip surface, makes iron scale peel off steel band under the mechanical momentum effect of water under high pressure.But because this complete equipment complex structure is with high costs, strengthened the input of enterprise, increased production cost.Therefore be necessary prior art is improved.
Summary of the invention
Remove the device structure complexity for solving existing steel band iron scale, investment is large, the problem that cost is high, and the utility model provides a kind of descaling of steel stock dust arrester.
The utility model is finished by following technical proposal: a kind of descaling of steel stock dust arrester, comprise the ground roll of being located at the steel billet exit, with the cover plate of being located on the ground roll, be located at the leakage slag chute of cover plate lower end and be located at backplate on the cover plate, it is characterized in that backplate is provided with connecting plate, this connecting plate is provided with the jet pipe that links to each other with feed pipe, and being positioned at jet pipe at backplate is close to and is provided with gripper shoe, be flexibly connected two screw rods on this gripper shoe, the two screw rods lower end is connected with overlaps the cross bar that two suspension hooks are arranged on it, movable hook hangs with its upper toothed scum board on two suspension hooks, so that after steel billet out enters on the ground roll, water under high pressure by jet pipe ejection makes the poly-cold contraction of its scale on surface and with after base substrate separates, strikes off by the iron scale scale of scum board with billet surface again, realizes the descaling of steel stock dedusting.
Described jet pipe comprises the VERTICAL TUBE that links to each other with feed pipe, two levels that are connected to the VERTICAL TUBE lower end are in charge of, the end that two levels are in charge of is made as the inclination pipe end of downward bending miter angle, so that the high-pressure cooling water that sprays can cover steel billet upper surface and two sides, to increase de-scaling dedusting area, ensure billet quality.
Described scum board upper and lower end is equipped with sawtooth, and both sides are provided with the waist hole, in order to be hooked on the suspension hook by the waist hole, and upper and lower end is used alternatingly, to prolong the service life of scum board.
The utlity model has following advantages and effect: adopt such scheme, by above the steel band of cooling, cooling water nozzle being set, thereby make the rapidly poly-cold contraction of iron scale of firm formation, then just can easily iron scale be peeled off by scum board.Simultaneously, in the spray cooling water, can also play the effect that suppresses dust, and the utility model is simple in structure, with low cost.Be a desirable steel band iron scale removal device in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the scum board structure chart among Fig. 1;
Fig. 3 is the nozzle structure figure among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The descaling of steel stock dust arrester that the utility model provides, comprise the ground roll 4 of being located at the steel billet exit, with the cover plate 1 of being located on the ground roll 4, be located at the leakage slag chute 2 and the backplate 5 of being located on the cover plate 1 of cover plate 1 lower end, backplate 5 is provided with two connecting plates 11, each connecting plate 11 is provided with the jet pipe that links to each other with feed pipe, this jet pipe comprises the VERTICAL TUBE 10 that links to each other with feed pipe, two levels that are connected to VERTICAL TUBE 10 lower ends are in charge of 3, two levels are in charge of the inclination pipe end that 3 end is made as downward bending miter angle, be positioned at jet pipe at connecting plate 11 and be close to flexible connection two screw rods 8, two screw rods 8 lower ends are connected with overlaps the cross bar 9 that two suspension hooks 7 are arranged on it, movable hook hangs with its upper toothed polylith scum board 6 on two suspension hooks 7, each scum board 6 upper, the lower end is equipped with sawtooth 12, and both sides are provided with waist hole 13, in order to be hooked on the suspension hook 7 by waist hole 13, can make during use, the lower end is used alternatingly, to prolong the service life of scum board 6.During work, steel billet a enters on the ground roll 4, the while water under high pressure is delivered to VERTICAL TUBE 10 through feed pipe and is in charge of 3 ejections through level again, make the poly-cold contraction of steel billet a scale on surface and with after base substrate separates, strike off by the iron scale scale of scum board 6 with billet surface again, realize the descaling of steel stock dedusting, ensure the billet rolling quality.
