Description
Technical field
The utility model relates to a kind of roller and meets adjusting device, and particularly a kind of shaped sectional roll of continuous casting meets adjusting device.
Background technology
Fan-shaped section is one of important stand-alone device of slab caster, be installed on the bottom of bending section, for the strand that goes out bending section is supported and led, provide enough external support to the strand in process of setting, effectively control the bulge deformation of strand, guarantee inside and the external mass of strand.Draw simultaneously and guide strand to align gradually horizontal direction along certain channel direction by arc, and the strand that goes out last fan-shaped section and solidified is completely transported on ejection roller way always.Size in order to ensure strand is accurate, up-to-standard, and fan-shaped section must have roll gap accurately.Meanwhile, a conticaster is in order to realize the process requirements of gently depressing, and quick response under conticaster abnormality, and the roll gap of fan-shaped section also must be able to regulate easily and fast.Above-mentioned two targets all need to meet adjusting device to decide by the roller of fan-shaped section.
Utility model content
For addressing the above problem, the utility model provides a kind of shaped sectional roll of continuous casting to meet adjusting device, realizes clamping and the lifting of fan-shaped section, is conducive to carrying out smoothly of continuous casting production.
For achieving the above object, shaped sectional roll of continuous casting of the present utility model meets adjusting device, comprise the displacement transducer of the described connecting rod displacement of hydraulic cylinder with double piston rods, connecting rod and detection, described hydraulic cylinder with double piston rods comprises cylinder body, is positioned at the piston of cylinder body, and two piston rods that are fixedly connected with described piston; Described connecting rod is fixedly connected with described two piston rods; Described cylinder body is fixedly connected with fan-shaped section upper frame, and described connecting rod is fixedly connected with fan-shaped section underframe; Described displacement transducer is fixedly connected with described cylinder body by a support.
Described cylinder interior is divided into epicoele and cavity of resorption by described piston, and the piston effective area of described epicoele is greater than the piston effective area of described cavity of resorption.
Shaped sectional roll of continuous casting of the present utility model meets adjusting device, forms relatively simply, and the manufacturing cost of equipment and maintenance cost are all relatively low, and uses reliably, and emergency response is fast.Adopt shaped sectional roll of continuous casting of the present utility model to meet adjusting device, improved roll gap degree of regulation and the response speed of fan-shaped section, be conducive to carrying out smoothly of continuous casting production.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that shaped sectional roll of continuous casting of the present utility model meets adjusting device to be connected with upper and lower framework;
Fig. 2 is the schematic diagram that shaped sectional roll of continuous casting of the present utility model meets adjusting device;
Fig. 3 controls the hydraulic control circuit figure that shaped sectional roll of continuous casting of the present utility model meets adjusting device to move.
The specific embodiment
Referring to Fig. 1 and 2, shaped sectional roll of continuous casting of the present utility model meets adjusting device to comprise hydraulic cylinder with double piston rods 10, connecting rod 20 and detects the displacement transducer 30 of described connecting rod 20 displacements, and described hydraulic cylinder with double piston rods 10 comprises cylinder body 11, is positioned at the piston 12 of cylinder body 11 and two piston rods 13,14 that are fixedly connected with described piston 12; Described connecting rod 20 passes two piston rods 13,14 of described hydraulic cylinder with double piston rods 10, and is fixedly connected with described piston rod 13,14; Described cylinder body 11 is fixedly connected with fan-shaped section upper frame 101, and described connecting rod 20 is fixedly connected with fan-shaped section underframe 102; Described displacement transducer 30 is fixedly connected with described cylinder body 11 by a support 31.
It is a pair of that shaped sectional roll of continuous casting of the present utility model meets adjusting device, is arranged on respectively the both sides of the upper and lower framework 101,102 of fan-shaped section.
Fan-shaped section upper frame 101 is connected with top roll 103, fan-shaped section underframe 102 is connected with lower roll 104, as shown in Figure 1, because piston rod 13,14 is fixedly connected with underframe 102 by connecting rod 20, cylinder body 11 is fixedly connected with upper frame 101, in the time will realizing the clamping of upper and lower framework 101,102, only need piston 12 to move up, and to realize the lifting of upper frame 101, upper and lower framework 101,102 separately time, only need piston 12 to move down.Because displacement transducer 30 is connected with cylinder body 11, when connecting rod 20 is in the time that cylinder body 11 moves, the displacement of connecting rod 20 relative cylinder bodies 11 just can be detected by displacement transducer 30, and the regulated value that this displacement is exactly shaped sectional roll of continuous casting to be met.The regulated value size of this roll gap can be accurately detected by displacement transducer 30, the degree of regulation of roll gap can be improved.
Fig. 3 is the hydraulic control circuit figure that controls shaped sectional roll of continuous casting of the present utility model and meet adjusting device action, and this hydraulic control circuit is mainly by stop valve 301,302, explosion-proof valve 303,307,308, and check valve 304,306, overflow valve 305, waits formation.When stop valve 301,302 is in opening state, explosion-proof valve 303 is in on-position, rapid answer valve 307 is in on-position, rapid answer valve 308 is in open position, pressure oil P enters the cavity of resorption 112 of hydraulic cylinder 10, the epicoele 111 of hydraulic cylinder is in oil return state, and now the framework up and down 101,102 of fan-shaped section is in clamped condition.When stop valve 301,302 is in opening state, explosion-proof valve 303 is in on-position, rapid answer valve 307 is in open position, rapid answer valve 308 is in on-position, pressure oil P enters the upper and lower cavity 111,112 of hydraulic cylinder simultaneously, because the piston effective area of the epicoele 111 of hydraulic cylinder is greater than the piston effective area of cavity of resorption 112, so hydraulic cylinder is realized differential motion, now fan-shaped section upper frame 102 can be realized fast lifting, to meet process requirements and emergency response is fast.The clamping of framework up and down 101,102 and the lifting of upper frame 101 of described fan-shaped section all adopt same pressure control, when the cavity of resorption 112 of hydraulic cylinder enters pressure oil P, when epicoele 111 oil return of hydraulic cylinder, realize the clamping of fan-shaped section.In the time that the upper and lower cavity 111,112 of hydraulic cylinder enters hydraulic oil P simultaneously, the differential motion of the difference in areas reality hydraulic cylinder by hydraulic cylinder upper and lower cavity 111,112, realizes the fast lifting of fan-shaped section.
