Description
Technical field
The invention belongs to rolling machinery, particularly the thermal straightening machine in a kind of Heavy Plate Production.
Background technology
Appearance along with the variation of market demands and new technology, new technology more and more need be configured to the finishing equipment one pre-straightening machine that quickly cooling device provides the steel plate pre-straightening, with security and the reliability that improves quick cooling on the Heavy Plate Production line.
Existing thermal straightening machine is generally nine rollers or 11 rollers, because the spacing between the working roll is less and all have backing roll, can't arrange the external refrigeration device, and therefore, the thermal straightening machine behind the rolling mill can only be arranged in after the quickly cooling device; More roller number in addition makes that the steel billet temperature of finishing after rolling is relatively low, and the yield strength of steel plate is bigger, and the straightening force during straightening steel plate is excessive.Because existing thermal straightening machine unreasonable structure can't be carried out pre-straightening to hot rolled steel plate under the condition of high temperature between rolling mill and the quickly cooling device, therefore, restricted the progress of Heavy Plate Production technology, has restricted the raising of product lumber recovery.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of cut deal pre-straightening machine is provided, solve existing thermal straightening machine unreasonable structure, the roller number is many, the problem that straightening force is excessive, thereby can carry out continuous pre-straightening to the high temperature steel plate, be the progress of Heavy Plate Production technology and the exploitation of new kinds of steel, provide equipment to guarantee.
The present invention is achieved by the following technical solutions:
A kind of cut deal pre-straightening machine is characterized in that: described pre-straightening machine is that device, outlet limit roller jacking system, bascule, moved cross beam, efficient cooling system, fast roll changing device, main drive and frame are formed by quick press down system, five roller rollers; Described frame is fixed on the basis by foundation bolt, and described quick press down system is installed in the top of described frame, and described bascule is connected with described frame and described walking beam respectively by hinged earrings; Described outlet limit roller jacking system is installed in the inside of described frame outlet side, and the outlet limit roller that is device by spiral lift and described five roller rollers is connected; It is the inner and described moved cross beam top of device that described efficient cooling system is installed in described five roller rollers, is connected with external water source by pipeline; Described fast roll changing device is lifting device, is connect a positioning clamping device and roller is that actuator is formed by roller, described roller is that lifting device is installed on the sill of described frame, describedly connect the transmission side that a positioning clamping device is installed in described frame, described roller is the fore side that actuator is installed in described frame, is that device is connected by connecting pin with described five roller rollers; Described main drive is installed on the basis, is that device is connected by universal-joint spindle with described five roller rollers.
Described quick press down system depresses by two that motor drives inlet side respectively and outlet side is depressed leading screw, and the described Motor Shaft end of depressing is equipped with hydraulic clutch.
The working roll that described five roller rollers are device adopts two times three arrangement, and top working roll has the big guide plate of entrance; The bottom working roll of outlet side is independently installed.
Described highly efficient cooling device comprises: have working roll inner cold water system, the outer cooling of the constant voltage injection system of swivel joint, and the circulating cooling system of walking beam.
The present invention is device because the present invention adopts five roller rollers compared with prior art, and the spacing between the working roll is big and all do not have backing roll, therefore, efficient cooling system can be set.Like this, can be between rolling mill and quickly cooling device, the steel plate of 700～1100 ℃ of high temperature is carried out continuous pre-straightening.Simultaneously, have the following advantages and beneficial effect:
1, can guarantee the reliability service of equipment by efficient cooling system;
2, can quick and precisely set the straightening process requirement of satisfying the different size steel plate to roll gap by quick press down system;
3, the independent adjustment by outlet roller position, limit effectively improves steel plate leveling effect end to end;
4, the fast roll changing device can be that device is changed fast to five roller rollers, has effectively shortened equipment downtime;
5, through the hot steel plate of pre-straightening machine, can effectively be discharged the internal stress that in the operation of rolling, produces, simultaneously, the steel plate glacing flatness effectively improves, thereby after having guaranteed that steel plate enters fast cooling device, uniformity and the uniformity of steel plate cooling have increased substantially the product lumber recovery.
