Casting box of roller for rod and wire and medium-wide strip steel rolling mill and using method thereof

Abstract

The invention discloses a casting box of a roller for a rod and wire and medium-wide strip steel rolling mill and a using method thereof. The casting box comprises an upper die, an upper end cover, acold mold, a lower end cover and a lower die which are vertically and sequentially connected from top to bottom; the upper die and the lower die are both of a double-layer structure, the lower die comprises a first vertical cylindrical inner steel die and a bottom box arranged outside the first inner steel die in a sleeving mode, and a cavity matched with the roller in shape is formed in the upperdie, the upper end cover, the cold mold, the lower end cover and the first inner steel die; and the upper die comprises a second cylindrical inner steel die and a riser box arranged outside the second inner steel die in a sleeving mode, and a second supporting plate is vertically arranged between the second inner steel die and the riser box. According to the casting box, the use amount of refractory clinker is reduced, investment of capital, manpower and time is reduced, pollution to the environment is reduced, the production efficiency is improved, the size of a cast blank is easy to guarantee, the surface roughness is reduced, and air holes and sand holes are reduced; and the using amount of the refractory clinker is reduced, and meanwhile the working environment of workers is improved.

Description

technical field [0001] The invention relates to the technical field of roll production and manufacturing, in particular to a casting box for rods and wires and rolls for medium and wide strip mills and a method for using them. Background technique [0002] The usual roll blanks are molded using a sand box and a roll model during casting, which takes a long time and requires a large amount of refractory clinker. The refractory clinker is generally river sand or quartz sand, which is mixed with a certain amount of clay in proportion. This traditional casting method not only needs to invest a lot of money, manpower and time, but also pollutes the environment greatly, the working environment is harsh, the production efficiency is low, and the cast blank has large size deviation, large surface roughness, and many pores and sand holes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a casting box for rods and wires and...
