Abstract
The utility model discloses a drawing-correcting roll for flat blank continuous casting. The utility model mainly solves the shortage of an existing drawing-correcting roll that the cooling effect of the existing drawing-correcting roll is not good enough. The surface of the designed drawing-correcting roll body is provided with a thread groove, wherein, the outer part of the thread groove is provided with a sleeve pipe; a spiral water channel for passing cooling water is formed between the sleeve pipe and the thread groove of the roll body. The utility model changes core segment indirect cooling of recirculated cooling water of the roll body into subsurface direct cooling. The utility model has the advantages that the service life of the drawing-correcting roll is prolonged, the forming quality of the flat blank is ensured, and unit production cost is reduced. The utility model is especially suitable for the arrangement of a large-scale arc drawing-correcting machine for flat blank continuous casting.
Description
The utility model relates to the critical component of sheet billet continuous casting straightening machine, refers to a kind of sheet billet continuous casting straightening roller particularly.
The especially large-scale arc slab of existing sheet billet continuous casting straightening machine tension leveller of continuous casting machine, the common middle water-cooling structure of the general employing of its straightening roller, be to have axial cooling water channel in the middle of the roll body, be provided with drainage tube in the water channel, cooling water enters the other end of drainage tube to roll body from the water inlet of roll body one end, turn back to the water inlet of roll body again by cooling water channel, discharge, take away heat from delivery port.Because roll body is more abundant, its cooling effect is very undesirable, causes the straightening roller to be easy to distortion under the strand hyperthermia radiation, influences the strand Forming Quality.More seriously be easy to generate crackle even fracture after the distortion of straightening roller, its working life is shortened dramatically, and roll change spare part expense costliness, roll change needs chronic, makes its unit cost of production high.
The purpose of this utility model is to provide a kind of cooling effect good, roll body long working life, the sheet billet continuous casting straightening roller that production cost is low.
For reaching this purpose, the sheet billet continuous casting straightening roller that the utility model is developed, comprise roll body with hollow cooling water channel, be provided with mozzle in the water channel of roll body, one end of roll body is provided with water inlet pipe that communicates with mozzle and the outlet pipe that communicates with water channel, roll body is processed with thread groove on the surface, thread groove is equipped with sleeve pipe outward, constitute the spirality bosh between sleeve pipe and the roll body thread groove, on the roll body away from advancing, the water channel of outlet pipe one end is provided with the water inlet through hole that links to each other with the spiral tank, near advancing, the water channel of outlet pipe one end is provided with the water outlet through hole that links to each other with the spiral tank, on the mozzle design have control cooling water flow to back-up ring.
Advantage of the present utility model is: constitute the spirality bosh between designed roll body thread groove and the sleeve pipe, this spiral tank both formed strong support to sleeve pipe, guaranteed the bearing capacity of straightening roller to the operating mode load; Again sleeve pipe is formed direct cooling, the recirculated cooling water that makes the straightening roller by core indirectly cooling make subsurface into and directly cool off.Thereby improved cooling velocity, improved cooling effect, prolonged the service life of straightening roller, guaranteed the slab Forming Quality.Simultaneously, the roll body of straightening roller is generally not fragile, and the replacing of straightening roller only limits to the replacing to sleeve pipe, thereby its unit cost of production also greatly reduces.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Accompanying drawing is a kind of sectional structure schematic diagram of sheet billet continuous casting straightening roller.
Straightening roller shown in the figure has a roll body 4, and roll body 4 has an axial hollow cooling water channel 16, is provided with a mozzle 2 in the cooling water channel 16, mozzle 2 from the end socket 1 of roll body 4 one ends always along extending near the plug 9 of the other end.Design has water inlet pipe 15 that communicates with mozzle 2 and the outlet pipe 3 that communicates with cooling water channel 16 near the end socket 1 of roll body 4.Finish turning machine-shaping has thread groove on the surface of roll body 4, the hot jacket interference fit that thread groove adopts outward is equipped with internal layer ordinary carbon steel cover 7, welding has outer stainless steel band 6 on the internal layer ordinary carbon steel cover 7, the finish turning moulding adopts this inside and outside double-deck sleeve pipe can further reduce the cost of manufacture and the replacement cost of straightening roller.Form spiral tank 10 between the thread groove of internal layer ordinary carbon steel cover 7 and roll body 4, spiral tank 10 two ends are by end cap 5 sealings.End design near plug 9 on roll body 4 has the water inlet through hole 8 that connects cooling water channel 16 and spiral tank 10, and the end design of close end socket 1 has the water outlet through hole 14 that connects cooling water channel 16 and spiral tank 10.Be equipped with on the mozzle 2 control cooling water flow to back-up ring 13, asbestos 11 and sealing ring 12 are housed on the back-up ring 13.
The utility model is in the process of work, cooling water enters mozzle 2 from water inlet pipe 15 earlier, enter in the cooling water channel 16 of roll body 4 one ends along mozzle 2 then, flow into spiral tank 10 by water inlet through hole 8, absorb the heat on the steel bushing 7,, flow back to the other end of cooling water channel 16 again by water outlet through hole 14 its direct cooling, discharge from outlet pipe 3 at last, circulation endlessly.
Claims (2)
1, a kind of sheet billet continuous casting straightening roller, comprise roll body with hollow cooling water channel, be provided with mozzle in the water channel of roll body, one end of roll body is provided with water inlet pipe that communicates with mozzle and the outlet pipe that communicates with water channel, it is characterized in that: roll body is processed with thread groove on the surface, thread groove is equipped with sleeve pipe outward, constitute the spirality bosh between sleeve pipe and the roll body thread groove, on the roll body away from advancing, the water channel of outlet pipe one end is provided with the water inlet through hole that links to each other with the spiral tank, near advancing, the water channel of outlet pipe one end is provided with the water outlet through hole that links to each other with the spiral tank, on the mozzle design have control cooling water flow to back-up ring.
