Abstract
The utility model relates to a casting roller of a double-roller casting and rolling machine, comprising a columniform casting roller body. A main shaft mounting hole is arranged on the casting roller body, two end faces on the casting roller body are respectively provided with an inclined plane the angle of which is 0.3-5 degrees. The inclined planes arranged on the two end faces on the casting roller body have the functions of reducing the contact surfaces between the two end faces on the casting roller body and a side seal plate, and improving the sealing effect of the two end faces on the casting roller body and the side seal plate. In addition, in the rotation process of the casting roller, abrasion is caused to the side seal plate, however, the two inclined planes on the casting roller body contact with the side seal plate with large contact area so that the abrasion speed of the side seal plate in the rotation process of the casting roller is slowed down, which is beneficial to prolonging the service life of the side seal plate.
Description
Technical field
The utility model relates to a kind of double-roller rolling machine equipment of producing the strip steel, the casting roller on particularly a kind of double-roller rolling machine equipment.
Background technology
Twin-roll cast-rolling mill is produced the strip steel, is molten steel directly is poured into by in two molten steel baths that rotation casting rollers and two side seal boards are formed relatively, and in two roller rotary courses, steel band casting below counterrotating two casting roller gaps goes out thin steel band.
On twin-roll cast-rolling mill, side seal board is positioned at the both ends of the surface of two casting rollers of twin-roll cast-rolling mill, and both ends of the surface and two casting rollers of relying on holding device to withstand on the casting roller form a molten steel bath.Existing casting roller is shown in accompanying drawing 1,2, and it comprises a columniform casting roller body 1, and casting roller body 1 is provided with spindle mounting hole 3, and two end faces of casting roller body 1 are a plane 2.When twin-roll cast-rolling mill approaches steel band in casting, side seal board at high temperature with in the temperature changing process can produce trickle distortion, the end face of casting roller and side seal board contact area are big more, sealing property is poor more, between casting roller roller end face and side seal board, produce the slit easily,, the phenomenon of bleed-out liquid will take place if produce the slit between casting roller roller end face and the side seal board, influence the steel band quality, when serious with breaks in production.Therefore, the end face of side seal board and casting roller is in conjunction with wanting closely reliable, and it is excessive from two end faces and the side seal board contact-making surface slit of casting roller to prevent to dissolve molten steel.
Summary of the invention
The purpose of this utility model be overcome the above-mentioned deficiency of prior art and a kind of casting roller roller end face is provided and the side seal board contact area less than the casting roller of prior art.
The technical solution of the utility model is: a kind of casting roller of twin roller caster, it comprises a columniform casting roller body, the casting roller body is provided with spindle mounting hole, and two end faces on the casting roller body are respectively equipped with an inclined-plane, the angle a=0.3 on inclined-plane～5 degree.Two end faces on the casting roller body are provided with the inclined-plane, and its effect is to reduce two end faces on the casting roller body and the contact-making surface of side seal board.
The utility model compared with prior art has following characteristics: because two end faces on the casting roller body are provided with an inclined-plane respectively, reduce two end faces on the casting roller body and the contact-making surface of side seal board, improved two end faces on the casting roller body and the sealing effectiveness of side seal board.In addition, when the casting roller caused wearing and tearing to side seal board in rotary course after, the inclined-plane at two ends contacted with side seal board on the casting roller body, because contact area increases, in the casting roller rotary course side seal board rate of wear was slowed down, favourable prolongation side seal board service life.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
