Description
Technical field
The present invention relates to continuous caster technical field, even cast hydraulic fan-shaped section of upper and lower frames clearance control method in particular to one.
Background technology
Continuous caster is for realizing soft reduction technique, segment roll gap adopts hydraulic control mode, the upper and lower frames of fan-shaped section connects with the column of lifting oil cylinder by 4, and the globe bearing of the mode of connection employing activity between column and framework, centering (i.e. the centering of up-down rollers system) before and after fan-shaped section upper and lower frames and between left and right is by being arranged at the guiding composition of fan-shaped section upper and lower frames respectively, for considering zeroing, the demand of the fan-shaped section lifting process such as slighter compress enforcement, the control in these guiding gaps is just relatively fuzzy in the design process, fan-shaped section is installed after reaching the standard grade because upper frame is from the reason of weight and various gap, define the spination defect of serious roll gap.
This kind of structure design of fan-shaped section is conducive to protecting lifting oil cylinder not damage by the impact of radial force in casting process or abnormality processing process; but the defect of spination roll gap; make the cold conditions management of casting machine roll gap very difficult; roll gap precision controlling is relatively poor and unstable; in casting process, the local pressure phenomenon of fan-shaped section and roller is serious, and work-ing life slab quality and fan-shaped section are caused very big impact.
Along with the development of world's continuous casting process, many continuous casters all have employed the form of hydraulic fan-shaped section, hydraulic fan-shaped section of various design all have employed certain technology to control the generation of this kind of spination roll gap, the Smart fan-shaped section comprising steel difficult to understand connection employs flexible link structure, the powerful side guiding structure of the Syberlink fan-shaped section of western mark and three articulated structures of Da Nieli fan-shaped section etc. The mode of these fan-shaped section control spination roll gap is different, and the effect reached also has bigger difference. And the situation of fan-shaped section in actual production, use procedure is also therefore different.
Summary of the invention
It is an object of the invention to provide and a kind of company cast hydraulic fan-shaped section of upper and lower frames clearance control method, not only fan-shaped section upper and lower frames is issued in the precondition that roller system aligns and does not affect descending operation and slighter compress Function implementation simultaneously but also can eliminate tooth shape roll gap defect, it is to increase the object of roll gap precision controlling level.
For achieving the above object, the technical scheme of the present invention is:
A kind of company casts hydraulic fan-shaped section of upper and lower frames clearance control method, and before and after described hydraulic fan-shaped section of upper frame, under the correspondence of side, the front posterior side of framework is established guiding mounting plate and connects orienting lug thereon by standing bolt; By fan-shaped section upper and lower frames off-line and be positioned on standard repair platform, maintaining frame is established in these standard repair platform both sides, and wherein establish can the screw block of jacking upper frame on the maintaining frame top of corresponding fan-shaped section inlet side; Open screw block, by upper frame progressively to fan-shaped section exporter to jacking, when the lower roll system center alignment of the upper roller system of fan-shaped section upper frame and lower framework, stop screw block jacking, measure the orienting lug on upper frame guiding mounting plate and gap value between side in lower framework guide plate simultaneously; Then carry out fan-shaped section disintegration, upper frame is hung; Unscrew the orienting lug standing bolt on fixing upper frame guiding mounting plate, select adjustment pad according to gap value as one-tenth-value thickness 1/10, and will adjust between pad insertion orienting lug and upper frame guiding mounting plate, then tighten standing bolt, finally make fan-shaped section close up.
Further, guiding mounting plate top outside the upper frame of corresponding fan-shaped section outlet side arranges upper frame measuring basis block; Outside guide plate outside the lower framework of corresponding fan-shaped section outlet side, measurement pedestal is set, and, measure pedestal outer side and erect to establishing measuring scale; It is a definite value between measuring scale and upper frame measuring basis block after even casting hydraulic fan-shaped section of normal mounting; Open screw block, by upper frame progressively to fan-shaped section exporter to jacking, measure the spacing between measuring scale and upper frame measuring basis block simultaneously, when this spacing equals described definite value, stop screw block jacking.
Again, the orienting lug Cross section Design on described hydraulic fan-shaped section of upper frame guiding mounting plate of corresponding fan-shaped section outlet side becomes semicircle cylinder.
In addition, described orienting lug is offered to fat hole and be connected with it, be positioned at surface give fat groove.
On described adjustment pad, corresponding described orienting lug has offered grease holes to fat hole, and on adjustment pad, slot offered by the corresponding described orienting lug standing bolt in both sides.
The invention has the beneficial effects as follows:
Cause the defect mode that mainly fan-shaped section upper and lower frames connects of casting stream spination roll gap and the control in guiding gap, front and back; Mode of connection is difficult to change, even if using the flexible link such as steel connection difficult to understand, also can cause the abnormal sequela such as the viscous deformation of radial force lower link and the damage of oil cylinder. And the clearance control difficulty that leads is bigger, when outlet gap is bigger, after fan-shaped section is installed on casting machine, the basic framework of its lower framework and casting machine is fixed, and because the upper frame that installation angle problem causes always makes upper frame tilt to cast direction from the base resistance of drawing of gravity and casting process, cause dislocation and the spination roll gap defect of up-down rollers system.
Therefore, the raising of the gap preset precision of hydraulic fan-shaped section with spination roll gap defect characteristic is very crucial by the present invention, it is inclined to by power online by simulation in off-line maintenance process, and by measuring, adjustment ensure fan-shaped section be installed on casting machine after the alignment of up-down rollers system and the therefore spination defect that causes, roll gap precision under the casting non-casting condition of stream is managed and casting process is subject to extremely equipment protection during power favourable, simultaneously, the elimination of serious spination roll gap, also be conducive to alleviating fan-shaped section in casting process and it be subject to the uneven roller caused of power, the quality defects such as the implosion that the damage of bearing and slab discontinuity cause, thus improve the work-ing life of fan-shaped section, ensure slab quality, improve caster work rate.
