Abstract
The invention discloses an inducing method and an educing device for the cast-rolling strip steels of a double-roller cast-rolling strip steel mill. Firstly, one end of an enduing belt extends into the space between two cast-rolling rollers; secondary; the other end of the educing belt passes through nip rolls through a rollaway nest; finally; the tail end of the educing belt is twisted on an educing belt coiling machine. The educing device of the invention comprises the educing belt (2), a tail belt (3), the rollaway nest (4), the nip rolls (5) and the educing belt coiling machine (7). The rollaway nest (4) is arranged at the lower part of the cast-rolling rollers (1); a group of nip rolls (5) are arranged on the rollaway nest (4); the back ends of the nip rolls (5) are provided with the educing belt coiling machine (7). The method and the device of the invention are simple and uniformly crystallized; a complete strip steel is formed at the beginning to prevent the generation of crack steel pieces and is led to the rollaway nest so as to move forwards in the rollaway nest, which ensures the product quality and improving the working efficiency.
Description
Technical field
The present invention relates to the steel rolling technology of iron and steel metallurgy industry, be specifically related to a kind of outbound course and ejector of rolling strip steel of double-roller rolling strip steel machine.
Background technology
When double-roller rolling strip steel machine carries out hot-strip production, be that high-temperature molten steel is directly poured into a pair of counterrotating casting roll shop building, molten steel is from the middle crystallization gradually of flowing from top to bottom of two rollers, and under the effect of two rolling system power, casting becomes sheet-type band steel from two roller gap outputs simultaneously.Pour into molten steel owing to have little time to be subjected to the cooling of casting roller early stage, is easy to generate discontinuous broken steel disc, influences production efficiency.
Summary of the invention
The objective of the invention is to: outbound course and ejector that a kind of rolling strip steel of double-roller rolling strip steel machine is provided, eliminate the generation of broken steel disc in early stage by this method and apparatus, form complete rolling strip steel at the very start, guarantee product quality, enhance productivity.
Technical solution of the present invention is that this method may further comprise the steps: at first, an end of leader tape stretches into two casting roll shop buildings; Secondly, the other end of leader tape passes clip wheel through raceway; At last, the leader tape tail end is wound on the leader tape coiling machine.
Leader tape thickness of the present invention is the 0.5-1.5 millimeter, and width is the 1/3-2/3 of casting roller body of roll width, and the leader tape built-in length is the 1/8-1/4 of casting roller circumference, and the leader tape length overall is that built-in length adds 20.3-20.8 rice.
Leader tape of the present invention is not held and is connected the tail band, and the other end of tail band passes clip wheel through raceway and is wound on the leader tape coiling machine, tail bandwidth 50-150 millimeter, and thickness 0.5-1.0 millimeter, length is 20 meters, leader tape length wherein is the 300-800 millimeter.
Ejector of the present invention comprises leader tape, tail band, raceway, clip wheel and leader tape coiling machine, below the casting roller raceway is installed, and one group of clip wheel is installed on the raceway, in the rear end of clip wheel the leader tape coiling machine is installed.
The leader tape cutter is installed between two pairs of clip wheels of the present invention.
During use, before molten steel does not pour into, leader tape is placed in the middle of two casting rollers, built-in length is the 1/8-1/4 of casting roller circumference; Inject molten steel and cool on leader tape early stage, and its temperature axially forms consistent gradually at leader tape, the band steel that homogeneously crystallized formation is complete; The band steel is after tail band and leader tape are drawn, the not end of tail band is rolled on the leader tape coiling machine, and when leader tape and band steel process raceway and clip wheel, the leader tape cutter is cut off the leader tape and melting welding place of band steel, leader tape is rolled on the coiling machine cylinder, and the band steel continues to advance on raceway.
Method and apparatus of the present invention is simple, and crystallization is even, forms complete band steel at the very start, prevents the generation of broken steel disc, and the pilot tape steel allows to the raceway the band steel march forward in raceway, guarantees product quality, enhances productivity.
