Abstract
The invention discloses a slab caster crystallizer spindle foot roll and belongs to continuous casting equipment components. The slab caster crystallizer spindle foot roll comprises a foot roll body which comprises a left foot roll body, a right foot roll body and a middle foot roll body, wherein the left foot roll body and the right roll body are respectively cylinder-shaped and are arranged symmetrically, and the middle foot roll body is in a spindle shape. Compared with the prior art, the slab caster crystallizer spindle foot roll has the advantages of having a supporting capacity of effectively optimizing a crystallizer narrow face foot roll, reducing bulging situations of a continuous casting blank on the narrow face, reducing casting blank edge cracks caused by casting blank side face bulging, guaranteeing the quality of the casting blank and the like, and therefore, the slab caster crystallizer spindle foot roll has very good popularization and application value.
Description
Technical field
The present invention relates to a kind of continuous casting installation for casting parts, especially a kind of slab caster mould spindle foot roller.
Background technology
Slab caster mould is substantially all to adopt cylindrical sufficient roller at present, and the problem of existence is: 1) along with the increase of casting blank section thickness, limit section and middle contraction gap increase; 2) strand easily produces bulge; 3) strand easily produces limit section crackle.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of slab caster mould spindle foot roller for above-mentioned deficiency of the prior art, this slab caster mould spindle foot roller has the enabling capabilities of effective optimization crystallizer narrow-face foot roller, reduce continuous casting billet in the bulge situation of leptoprosopy, the strand limit of reducing that strand side bulge causes is split, and guarantees the characteristics of the quality of strand.
The technical solution adopted for the present invention to solve the technical problems is: it comprises sufficient roller body, described sufficient roller body comprises left sufficient roller body, right sufficient roller body and middle part foot roller body, described left sufficient roller body and right sufficient roller body are respectively cylindrical, described left sufficient roller body and right sufficient roller body are symmetrical arranged, and described middle part foot roller body is for spinning the Duo shape.
Be provided with the gap of 3cm between the edge periphery of described left sufficient roller body and right sufficient roller body and strand.
The length of described left sufficient roller body and right sufficient roller body is respectively 30cm-50cm.
The length of described left sufficient roller body and right sufficient roller body is respectively 30cm.
Slab caster mould spindle foot roller of the present invention compared to the prior art, has following outstanding beneficial effect: the enabling capabilities of, hardness different effective optimization crystallizer narrow-face foot rollers different according to mould at narrow strand up and down, medium temperature, reduce continuous casting billet in the bulge situation of leptoprosopy, reduce the strand bight reaction force to sufficient roller framework really up to the mark; On the one hand guaranteed that casting blank shape meets technological requirement, the strand limit of reducing on the other hand that strand side bulge causes is split, guarantee strand quality etc. characteristics.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic diagram of slab caster mould spindle foot roller;
Description of reference numerals: 1, left sufficient roller body, 2, middle part foot roller body, 3, right sufficient roller body.
The specific embodiment
Be described in detail below with reference to 1 pair of slab caster mould spindle foot roller of the present invention of Figure of description.
Slab caster mould spindle foot roller of the present invention, its structure comprises sufficient roller body, described sufficient roller body comprises left sufficient roller body 1, right sufficient roller body 3 and middle part foot roller body 2, described left sufficient roller body 1 and right sufficient roller body 3 are respectively cylindrical, described left sufficient roller body 1 and right sufficient roller body 3 are symmetrical arranged, and described middle part foot roller body 2 is for spinning the Duo shape.
Be provided with the gap of 3cm between the edge periphery of described left sufficient roller body 1 and right sufficient roller body 3 and strand.
The length of described left sufficient roller body 1 and right sufficient roller body 3 is respectively 30cm-50cm.
The length of described left sufficient roller body 1 and right sufficient roller body 3 is respectively 30cm.
During use, the middle part of spinning the middle part foot roller body 2 of Duo shape contacts with strand, the enabling capabilities of, hardness different effective optimization crystallizer narrow-face foot rollers different according to mould at narrow strand up and down, medium temperature, reduce continuous casting billet in the bulge situation of leptoprosopy, reduce the strand bight reaction force to sufficient roller framework really up to the mark; On the one hand guaranteed that casting blank shape meets technological requirement, the strand limit of reducing on the other hand that strand side bulge causes is split, and guarantees the quality of strand.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
