Description
Technical field
The utility model relates to survey instrument, particularly conticaster hydraulic pressure fan-shaped section up and down framework between the gap gauge measuring and control.
Background technology
For improving slab quality, realize light press function, conticaster has all adopted hydraulic fan-shaped section of Japanese SPCO design, the framework up and down of this fan-shaped section connects with 4 oil cylinders, adopt mobilizable globe bearing to be connected between oil cylinder and the framework, realize by the front and back of fan-shaped section and the guide plate of two sides location between the framework up and down, 4 oil cylinders are lifting control roll gap separately, this design feature is under the fan-shaped section situation that gap, framework front and back exceeds standard up and down, when fan-shaped section be in place (particularly arcuate segments), it is from the change of gravity direction, and 4 oil cylinder liftings when asynchronous (actual can not synchronously), certainly leads to the zigzag of casting machine roll gap.Behind the cast certain hour, with situations such as the distortion of equipment, uneven wears, it is bigger and more in disorder that this zigzag progressively becomes.
Theoretically will, this zigzag roll gap can return to theoretical gap values between rollers with the directive effect power of driven roller running in casting process, but because zigzag is serious, part driven roller pressed compact not in the casting machine actual production process, and the driven roller position is unusual, makes the recovery difficulty of zigzag roll gap.
Most zigzag roll gap is irrecoverable in casting process, and the part position is because of being subjected to the influence of throwing power simultaneously, and the physical location in the casting process becomes lower.
Above-mentioned these situations have caused continuous casting machine fan-shaped segment low serviceable life, designed lives 5000 stove, the actual use less than 3000 stoves, particularly segmental arc (serviceable life is less than 2000 stoves), roll breakage, damage of bearings is very frequent, slab quality also is subjected to very big influence.
Hydraulic fan-shaped section zigzag roll gap is a kind of commonplace defect, hydraulic fan-shaped section employing pedestal of VAI company design fixed and controlled the gap, front and back of framework up and down from the oil cylinder of tape guide, this structural design is (under the situation of unusual throwing) when casting machine bears extra pulling force, the oil cylinder column is stressed serious, cause column to become curved, problems such as oil cylinder internal leakage easily; Hydraulic fan-shaped section of Da Nieli and the design of western mark company is adopted the extra balanced controls control gap of framework up and down, online fan-shaped section cold conditions detects has a spot of zigzag phenomenon to exist, can recover in the cast, but its structure is relatively complicated, under the unusual stress, oil cylinder is stressed equally after the balanced controls deformation failure, and phenomenons such as oil cylinder internal leakage still exist.
Adopt the mode of framework guiding to solve the problem of cylinder force by conticaster hydraulic pressure fan-shaped section, but the fan-shaped section guiding clearance of framework is up and down controlled the particular importance that becomes, but just because of the framework denser of this fan-shaped section, off-line and onlinely all can't measure this gap value.
Goal of the invention
The purpose of this utility model is to design framework clearance measurement gauge about in the of a kind of hydraulic fan-shaped section, can detect the hydraulic fan-shaped section front and back gap value between the framework up and down, and adjust by the gap, to subdue or to eliminate the zigzag of this hydraulic fan-shaped section online roll gap significantly.
For achieving the above object, the technical solution of the utility model is,
Framework clearance measurement gauge about in the of hydraulic fan-shaped section, it comprises, gage beam, it is a joist steel, has a workplace; Gage beam one end is established a hole for hoist; Two bracing frames are installed on an end of gage beam one workplace; Two fastening blocks are individually fixed in described two bracing frame outer faces; Offer bolt hole on the fastening block; Reference block is arranged at the other end of gage beam one workplace; Two upper frame reference blocks are arranged at upper frame, the reference block on corresponding gage beam one workplace; Once the frame of reference piece is arranged at underframe, and the fastening block on corresponding gage beam one workplace on two bracing frames is connected with fastening block by bolt during measurement.
During measurement, at each hydraulic fan-shaped section outlet side 4 measuring basis faces of framework both sides processing up and down---framework reference block (each one up and down of every side up and down, wherein descend reference field to also have the bolt hole of fixed size gauge), each reference field is a fixed value to the distance between center line of outlet first pair of rollers;
After fan-shaped section rolls off the production line, two gauge are installed to two following reference fields and fixing (two gauges carry out simultaneously) of fan-shaped section outlet side, then to measuring under gauge and the fan-shaped section, by measuring the gap value of determining each side, fan-shaped section disintegrate (before closing up) the back lead block brass of fan-shaped section upper frame is carried out the pad adjustment.
The beneficial effects of the utility model
Use by this gauge, can be significantly less and eliminate the zigzag of online segment roll gap, improve the cold conditions management level of casting machine roll gap, reduce the stressed concentration phenomenon of roller, improve the serviceable life of continuous casting machine fan-shaped segment, reduction can't recover influence to casting billet surface and internal soundness because of the zigzag roll gap in cast, improve the heat of strand and send rate, improves fan-shaped section serviceable life.

Embodiment
Referring to Fig. 1～Fig. 4, the utility model is framework clearance measurement gauge about in the of hydraulic fan-shaped section, and it comprises, gage beam 1, and it is a joist steel, has a workplace 101; Gage beam 1 one ends are established a hole for hoist 102; Two bracing frames 2,3 are installed on an end of gage beam 1 one workplaces 101; Two fastening blocks 4,5 are individually fixed in described two bracing frames 2,3 outer faces; Offer bolt hole 41,51 on the fastening block; Reference block 6 is arranged at the other end of gage beam 1 one workplaces 101; Two upper frame reference blocks 7,8 are arranged at upper frame 12, the reference block 6 on corresponding gage beam one workplace 101; Once the frame of reference piece 9, are arranged at underframe 13, and the fastening block 4,5 on corresponding gage beam one workplace 101 on two bracing frames is connected with fastening block 4,5 by bolt 10,11 during measurement.
Fan-shaped section rolls off the production line before the maintenance, earlier fan-shaped section is winched to test board, with hydraulic means the aperture of fan-shaped section is risen to 250mm, with lifting jack upper frame is pushed up backstop and contacts (simulation fan-shaped section reach the standard grade the stress under the casting condition) with the oriention benchmark face in downward right side in the porch of fan-shaped section;
Two interradicular space gauge are contained in respectively on two reference fields of bottom, fan-shaped section exit and and fix with fastening bolt; Measure the distance of gauge upper end (noncontact face) with milscale to the upper frame reference field.
According to measured value and standard value relatively, that is: the brass pad amount adjusted of standard value-measured value=needs is on the occasion of (increase brass pad respective thickness, negative value (deducting brass pad respective thickness).
The fan-shaped section breakdown maintenance is adjusted fan-shaped section upper frame pad according to comparative result before framework closes up up and down, can guarantee that the gap in fan-shaped section exit under the state of roller system alignment is 0.
