And the both ends of upper mold roller 605 and lower mold roller 602 are disposed as taper, on the one hand can quickly eliminate steel band 2 and apply strong cold mistake in essence
On the other hand the thermal stress generated in journey can will be corrected by upper mold roller 605 and the steel band 2 in lower 602 gap of mold roller, usually be pressed
Two groups of means for correctings 6 are set gradually according to the conveying direction of steel band 2, further improve production efficiency.
In order to adapt to the needs of high-speed production, strip needs to be in tensioning state in transmission process, up to nearly two
On hundred meters of production line, to realize that the tensioning of strip is a very difficult thing, as the present invention another inventive point,
Inventor has studied a set of tension balance device 4, this set tension balance device 4 is arranged in following several positions of production line,
Entry loop device front and back position is respectively provided with a set of tension balance device 4, and a set of be somebody's turn to do is arranged before steel band 2 enters rendering machine
A set of tension balance device 4 is arranged in tension balance device 4 after the strong device for cooling of rendering, is set after essence applies strong device for cooling 5
A set of tension balance device 4 is set, a set of tension balance device 4 is set after outlet looping device, it in this way can be effective
Solve the problems, such as tensioning of the steel band 2 in entire transmission process.As shown in figure 4, the tension balance device 4 includes support base 401, branch
It is arranged in sequence with the first equal jockey pulley 403 of diameter, the second jockey pulley 404, third jockey pulley 405 and the 4th on support seat 401
Jockey pulley 406, the first jockey pulley 403, the second jockey pulley 404, the center line of third jockey pulley 405 and the 4th jockey pulley 406 are flat
It row setting and is rotatably installed on support base 401 by bearing block, wherein the second jockey pulley 404 and third jockey pulley 405
Axial location is higher than the axial location of the first jockey pulley 403 and the 4th jockey pulley 406, and a force is mounted on every jockey pulley
Roller 407, the rotational installation of roll force 407 are cranked arm in one on 408, and 408 one end of cranking arm are hinged on support base 401, the other end and one
Cylinder 409 is connected, and steel band 2 is pressed on the surface of jockey pulley by roll force 407, and support base 401 is equipped with gantry beam 402, dragon
Door beam 402 is hinged with an adjustment arm 410 between the second jockey pulley 404 and third jockey pulley 405 on gantry beam 402, adjust
The both ends of arm 410 are rotatablely equipped with a pressure roller 411 respectively, and two pressure rollers 411 are pressed respectively against the second jockey pulley 404 and third jockey pulley
On 405.In use, steel band 2 initially enters the second jockey pulley 404, then pile warp the first jockey pulley 403 and the 4th jockey pulley 406,
It is exported by third jockey pulley 405, when the tension of 402 both sides steel band 2 of gantry beam changes, adjustment arm 410 will be put therewith
Dynamic, pressure roller 411 just presses to the small side of tension, generates tensile force, the then adjustment good position in advance as needed of roll force 407, and one
Aspect can ensure cornerite of the steel band 2 on jockey pulley, on the other hand steel band 2 can be given to apply tensile force in advance, pressure roller 411 exists
Play the role of adjusting tensile force at any time in the course of work, is a quick condition, thus solves steel band 2 well defeated
Tension variation during sending, ensure that spraying effect and production efficiency.
