Abstract
The invention relates to a rapid arc connecting method for a narrow-face foot roller of a slab continuous casting machine crystallizer, which comprises the following steps of: 1) firstly, fixing two sides of a foot roll on a foot roll support through L-shaped clamping plates, then adding 10 groups of disc spring plates at the rear part of the foot roll support to be flexibly connected with a foot roll billet so as to prevent a casting blank from bulging due to molten steel static pressure, and finally installing the assembled foot roll device in U-shaped grooves at two sides of the lower end of a Z-shaped supporting plate; 2) the foot roll arc connecting operation is realized by adjusting two adjusting bolts behind the foot roll bracket to realize arc connection with the copper plate, and the foot roll is locked by the double spare caps of the stud bolts; 3) the arc connection is completed at one time through the adjustment of a speed reducer-screw mechanism. Compared with the prior art, the invention has the beneficial effects that: the method has the characteristics of low investment, simple method, science and practicality, reduces the fault time of equipment, improves the arc connecting precision of the process, reduces the labor intensity of workers, improves the working efficiency and creates higher economic benefit for enterprises.
Description
Technical field
The present invention relates to technical field of metallurgical machinery, particularly a kind of quick arc method of slab caster mould narrow-face foot roller.
Background technology
Large conticaster has now used nearly 20 years; side guide roller system of its whole section by: hydraulic motor-worm reduction gear-screw-nut mechanism-leptoprosopy deflector roll forms; due to working environment high temperature humidity; being produced covering slag corrodes; when carrying out the adjustment of leptoprosopy roller, often because screw body generation screw-nut fault, reductor fault and various machinery, hydraulic fault cause completing within the stipulated time at production interval the wide action of tune.Cause to produce and interrupt, by forced-stopping machine, rushed to repair, each integral body section of changing needs about at least four hours, existing rhythm of production is caused to serious impact, according to statistics from first arrival in 2008 in August, 2012 because the leptoprosopy roller is adjusted motionless and can't be processed online to cause and be forced to change whole section totally 33 times; Slab cast machine is in order to prevent bleed-out and slab side bulge, nearly 12 of foot roller quantity, its type of belt drive is: hydraulic control system-hydraulic motor-turbine worm reducer-screw mandrel screw-narrow-face foot roller mechanism, its complex structure, the driving-chain complexity, operating mode is severe, and fault rate is high, is once affecting production.
Summary of the invention
The purpose of this invention is to provide the fault time that a kind of method is simple, reduce equipment, improve the quick arc method of the slab caster mould narrow-face foot roller that connects the arc precision of technique.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of quick arc method of slab caster mould narrow-face foot roller comprises the following steps:
1) at first sufficient roller both sides are fixed on sufficient roller support by the L-type clamp, then set up 10 groups of dish reeds at sufficient roller support rear portion and sufficient roller steel billet is flexibly connected, prevent that ferrostatic pressure from causing casting blank bulging, carry out the wearing layer plating in sufficient roller support both sides afterwards, realize good lubrication, finally the foot-roller unit assembled is arranged in the U-shaped groove of both sides, Z-shaped gripper shoe lower end;
2) sufficient roller connects arc operation latter two is adjusted bolt and realizes being connect arc with copper coin by adjusting sufficient roller support, and the locking of sufficient roller realizes locking by the two standby cap of stud;
3), after being assembled into the well-defined crystal device, by reductor-screw mechanism adjustment, realize that once connecing arc completes, and meets Production requirement.
3 U-shaped grooves are offered respectively in both sides, described Z-shaped gripper shoe lower end.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of quick arc method of slab caster mould narrow-face foot roller, there are small investment, method is simple, science is practical characteristics, effectively reduce the fault time of equipment, that has improved technique connects the arc precision, reduced workman's labour intensity, improve the rate of totally starting of operating efficiency and equipment, met production requirement, reduced fault rate.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As described in Fig. 1～Fig. 3, a kind of quick arc method of slab caster mould narrow-face foot roller comprises the following steps:
1) at first sufficient roller 8 both sides are fixed on sufficient roller support 3 by L-type clamp 4, then set up 10 groups of dish reeds 5 is flexibly connected with sufficient roller steel billet at sufficient roller support 3 rear portions, prevent that ferrostatic pressure from causing casting blank bulging, carry out the wearing layer plating in sufficient roller support 3 both sides afterwards, realize good lubrication, finally the foot-roller unit assembled is arranged in the U-shaped groove 2 of Z-shaped gripper shoe 1 both sides, lower end;
2) sufficient roller connects arc operation latter two is adjusted bolts 6 and realizes being connect arc with copper coin 9 by adjusting sufficient roller support 3, and the locking of sufficient roller 8 realizes locking by the two standby cap of stud 7;
3), after being assembled into the well-defined crystal device, by reductor-screw mechanism adjustment, realize that once connecing arc completes, and meets Production requirement.
3 U-shaped grooves 2 are offered respectively in above-mentioned Z-shaped gripper shoe 1 both sides, lower end.
Above described be only basic principle of the present invention, not the present invention is imposed any restrictions, everyly according to the present invention, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
