Abstract

The utility model relates to a conticaster crystallizer copper pipe and sufficient roller arrangement structure of crystallizer belongs to metallurgical industry casting machine technical field. Technical scheme is: contain crystallizer copper pipe (1) and the sufficient roller of crystallizer, crystallizer copper pipe (1) one end is equipped with crystallizer copper pipe (2) suitable for reading, and the other end is equipped with crystallizer copper pipe end opening (3), and the sufficient roller of crystallizer is established and is located at crystallizer copper pipe end opening (3), the sufficient roller of crystallizer contains sufficient roller (4) and sufficient roller two (5), and two (5) edge crystallizer copper pipe (1) central line both sides symmetrical arrangement on sufficient roller (4) and the sufficient roller, sufficient roller (4) and sufficient roller are less than the internal diameter that end opening (3) were managed to crystallizer copper apart from L between two (5). The beneficial effects of the utility model are that: through the sufficient roller opening degree of adjustment crystallizer, the life of crystallizer copper pipe can prolong 50%, and the steel volume of crossing of crystallizer copper pipe increases by 50% equally, has reduced manufacturing cost.

Description

Crystallizer copper pipe of continuous casting machine and crystallizer foot roll arrangement
Technical field
The utility model relates to a kind of crystallizer copper pipe of continuous casting machine and crystallizer foot roll arrangement, belongs to metallurgy industry continuous casting installation for casting technical field.
Background technology
In metallurgy industry continuous casting process, conticaster is one of visual plant, and its crystallizer foot roll opening degree is consistent with crystallizer copper pipe bottom size, is convenient to crystallizer copper pipe, the operating arc of sufficient roller.
Billet caster crystallizer arranges sufficient roller, and its effect guides dummy bar to enter crystallizer, and also shield to crystallizer copper pipe, when preventing from sending dummy bar, dummy bar head breaks crystallizer copper pipe end opening simultaneously; Another effect of foot roller plays supporting and guide effect to the strand of pull-out crystallizer, namely the weak base shell just going out copper pipe is play supporting role, reduce casting blank deformation or bleed-out, also can alleviate the wearing and tearing of strand to crystallizer copper pipe end opening, casting blank deformation is little, breakout ratio is low.
Crystallizer foot roll opening degree, the minimum range namely between two sufficient rollers is identical with crystallizer copper pipe bottom size, easy centering to arc, convenient operation.But this arrangement, the quick abrasion of crystallizer copper pipe end opening, directly affects the service life of crystallizer copper pipe.
Utility model content
The utility model object is to provide a kind of crystallizer copper pipe of continuous casting machine and crystallizer foot roll arrangement, makes crystallizer foot roll opening degree be less than the internal diameter of crystallizer copper pipe end opening, extends the service life of crystallizer copper pipe, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of crystallizer copper pipe of continuous casting machine and crystallizer foot roll arrangement, comprise crystallizer copper pipe and crystallizer foot roll, it is suitable for reading that described crystallizer copper pipe one end is provided with crystallizer copper pipe, the other end is provided with crystallizer copper pipe end opening, crystallizer foot roll is located at crystallizer copper pipe end opening place, described crystallizer foot roll comprises sufficient roller one and sufficient roller two, foot roller one and sufficient roller two are arranged along crystallizer copper pipe center line bilateral symmetry, and the distance L between sufficient roller one and sufficient roller two and crystallizer foot roll opening degree are less than the internal diameter of crystallizer copper pipe end opening.
Described crystallizer foot roll is outer arc foot roller in crystallizer.
Sufficient roller one in described crystallizer foot roll and the distance L between sufficient roller two are less than the internal diameter 0.5-0.8mm of crystallizer copper pipe end opening.
Adopt the utility model, sufficient roll shaft eccentric stiffener is utilized to adjust outer arc foot roller opening degree in crystallizer, it is made to be less than the internal diameter of crystallizer copper pipe end opening, base shell and crystallizer foot roll touch scrolling pull out, reduce base shell to the contact of crystallizer copper pipe, and then reduce base shell to the wearing and tearing of crystallizer copper pipe and scuffing, reach the object extending crystallizer copper pipe service life, by adjustment crystallizer copper pipe opening degree, continuous casting is made to produce the object reaching cost efficiency.
The beneficial effects of the utility model are: by adjustment crystallizer foot roll opening degree, the service life of crystallizer copper pipe can extend 50%, and the steel transportation amount of crystallizer copper pipe increases by 50% equally, reduces production cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: crystallizer copper pipe 1, crystallizer copper pipe are suitable for reading 2, crystallizer copper pipe end opening 3, sufficient roller 1, sufficient roller 25.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of crystallizer copper pipe of continuous casting machine and crystallizer foot roll arrangement, comprise crystallizer copper pipe 1 and crystallizer foot roll, described crystallizer copper pipe 1 one end is provided with crystallizer copper pipe suitable for reading 2, the other end is provided with crystallizer copper pipe end opening 3, crystallizer foot roll is located at crystallizer copper pipe end opening 3 place, described crystallizer foot roll comprises sufficient roller 1 and sufficient roller 25, foot roller 1 and sufficient roller 25 are arranged along crystallizer copper pipe 1 center line bilateral symmetry, and the distance L between sufficient roller 1 and sufficient roller 25 and crystallizer foot roll opening degree are less than the internal diameter of crystallizer copper pipe end opening 3.
In the present embodiment:
(1) first crystallizer copper pipe confirms crystallizer copper pipe opening degree before using, and surveys the size of crystallizer copper pipe end opening 3;
(2) sufficient roll shaft eccentric stiffener is utilized to adjust crystallizer foot roll opening degree size;
(3) crystallizer side arc foot roller opening degree is equal with the internal diameter width of crystallizer copper pipe end opening;
(4) outer arc foot roller opening degree in crystallizer, the distance L namely between sufficient roller 1 and sufficient roller 25 is less than the internal diameter 0.5-0.8mm of crystallizer copper pipe end opening 3, and square billet removes the limit, rectangular bloom capping;
(5) base shell and crystallizer foot roll touch scrolling pull out, and reduce base shell to the contact of crystallizer copper pipe 1, and then reduce base shell to the wearing and tearing of crystallizer copper pipe 1 and scuffing, reach the object extending crystallizer copper pipe 1 service life, reduce cost, improve efficiency.According to statistics, crystallizer copper pipe 1 steel transportation amount can increase by 50%, and crystallizer copper pipe 1 extends 50% service life.
