Abstract
The invention belongs to the technical field forming, relating to a segment of a gapless roll gap adjustment device. The segment is consists essentially of an upper frame, a lower frame, an upper driving roll lifting device, a roll gap adjustment hydraulic cylinder, roll gap adjustment devices and a roll, and is characterized in that the upper frame of the segment is connected with the lower framethrough four same roll gap adjustment devices; the upper driving roll lifting device is installed on the upper frame; and the roll gap adjustment hydraulic cylinder is fixed on the upper frame of the segment. When roll gap adjustment is needed, a piston inside the roll gap adjustment hydraulic cylinder fixed on the upper frame moves, the roll gap adjustment device connected with a piston rod driv es the upper frame of the segment to be lifted up and down by the stretch of the piston rod, thus realizing roll gap adjustment. The roll gap adjustment device is internally provided with a guide mechanism used for guiding so as to lead the upper frame to be lifted stably. The segment has the advantages of compact structure, good stability, simple and convenient operation and maintenance, and can be widely applied in the segments of slab casting machines.
Description
Technical field
The invention belongs to field shaping technique, relate to a kind of fan-shaped section of not having the gap roll gap adjustment device.
Background technology
Along with the fast development of China's steel and iron industry, the continuous casting installation for casting of China is synchronized development thereupon also, and has created condition for the smooth fast development of steel and iron industry.Fan-shaped section is a kind of visual plant in the conticaster, and after the strand that comes out from crystallizer arrived fan-shaped section through bending section, strand base shell in fan-shaped section continued to increase, and solidifies fully until strand.The mode that segment roll gap is regulated is that four hydraulic cylinders are realized the adjusting of roll gap by the roll gap governor motion.
At present, the roll gap of fan-shaped section is regulated the roll gap governor motions that adopt door assembly with hinge and glass in right hand and left point more in the slab caster, and this roll gap regulative mode can influence the roll gap degree of regulation of fan-shaped section because hinge point in order to satisfy the needs of assembling, has certain clearance.
Summary of the invention
The objective of the invention is provides a kind of fan-shaped section of not having the gap roll gap adjustment device in order to improve the segment roll gap degree of regulation.The present invention mainly is made up of upper frame, underframe, last driven roller lowering or hoisting gear, roll gap regulator solution cylinder pressure, roll gap adjustment device and roller, and it is characterized in that: the fan-shaped section upper frame is connected with underframe by the identical roll gap adjustment device of quadruplet; Last driven roller lowering or hoisting gear is installed on the upper frame; Roll gap regulator solution cylinder pressure is fixed on the fan-shaped section upper frame.
This equipment is regulated segment roll gap by a kind of flexible link roll gap adjustment device of not band gap, can improve the segment roll gap degree of regulation.In roll gap adjustment device, be provided with roll gap and regulate the hydraulic cylinder piston rod guider, play protection roll gap regulator solution cylinder pressure.
Purpose of the present invention realizes in the following way: the segment roll gap adjusting device is by Driven by Hydraulic Cylinder, and the fan-shaped section upper frame carries out lifting by roll gap adjustment device under the driving of hydraulic cylinder.Flexible link is regulated the employing of hydraulic cylinder piston rod guider with roll gap and is threaded, and the roll gap difference of fan-shaped section import and outlet is realized by flexible link.Outside flexible link, be provided with fan-shaped section upper frame lifting and guiding device, play guiding at the casting flow path direction with perpendicular to the casting flow path direction; On the fan-shaped section upper frame lifting and guiding device distance block is set, can carries out fan-shaped section benchmark intermesh determination and different gap values between rollers is set.
Compact conformation of the present invention, good stability, simple and convenient operation and maintenance can be widely used in the segments of slab section.
Description of drawings
Fig. 1 is a front view of the present invention
Fig. 2 is a left side view of the present invention
Fig. 3 is an A-A cutaway view of the present invention
Among the figure: part 1 is a upper frame, part 2 is underframes, part 3 is to go up the driven roller lowering or hoisting gear, and part 4 is roll gap regulator solution cylinder pressures, and part 5 is that (part 5-1 is a lead to roll gap adjustment device, part 5-2 is the upper frame lifting and guiding device, part 5-3 is a flexible link, and part 5-4 is a nut), part 6 is rollers, part 7 guide plates, part 8 distance blocks.
The specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is described further:
Fan-shaped section upper frame 1 is connected with underframe 2 by the identical roll gap adjustment device 5 of quadruplet; Last driven roller lowering or hoisting gear 3 is installed on the upper frame 1; Roll gap regulator solution cylinder pressure 4 is fixed on the fan-shaped section upper frame 1.
The piston rod of roll gap regulator solution cylinder pressure 4 is connected with the lead 5-1 of roll gap adjustment device 5; Upper frame lifting and guiding device 5-2 is separately fixed at up and down on the framework 1,2; Lead 5-1 and flexible link 5-3 are with being threaded, and flexible link 5-3 is installed in the upper frame lifting and guiding device 5-2, and fixing with nut 5-4 and fan-shaped section underframe 2.
Fan-shaped section upper frame lifting and guiding device 5-2 is provided with guide plate 7 at the casting flow path direction with perpendicular to the casting flow path direction, and is provided with distance block 8, carries out fan-shaped section benchmark intermesh determination.
Last driven roller lowering or hoisting gear 3 can carry out lifting by two hydraulic cylinders, also can carry out lifting by a hydraulic cylinder.
When adopting fixedly roll gap production, select distance block 8 to regulate, different gap values between rollers is set.
When the needs roll gap is regulated, be fixed on the piston motion in the roll gap regulator solution cylinder pressure 4 on the upper frame 1, the roll gap adjustment device 5 that is connected with piston rod is flexible by piston rod, drives upper frame 1 lifting realization roll gap and regulates.Framework lifting and guiding device 5-2 on fan-shaped section plays guiding at the casting flow path direction with perpendicular to casting the guide plate 7 that flow path direction is provided with in the roll gap adjustment process, protect flexible link 5-3 simultaneously.
Compact conformation of the present invention, good stability, simple and convenient operation and maintenance can be widely used in the segments of slab section.
