Abstract
The invention relates to the field of steel-rolling production, in particular to a connected square-steel structure. The technical problem to be solved is to provide the connected square-steel structure which can be used for producing less than 80mm of square steel by utilizing a large-scale rail-beam rolling mill. The connected square-steel structure comprises an even number of square steel which are sequentially connected, wherein one edge of one square steel is connected with one edge of another square steel through a square-steel transition segment, and the axially-symmetrical central lines of all the square steel are positioned on the same plane. A product with the connected square-steel structure is formed through the rolling of the rolling mill with the connected hole shape matched with the connected square-steel structure. According to the connected square-steel structure, a plurality of connected square-steel products can be once directly produced through the connected hole shape of the large-scale rail-beam rolling mill by designing the square-steel products with the connected structures, so that the production efficiency is greatly improved, and the large-scale rail-beam rolling mill is also fully utilized. The connected square-steel structure can be used for manufacturing less than 80mm of small and medium-size square steel by utilizing the large-scale rail-beam rolling mill.
Description
Technical field
The present invention relates to steel rolling production field, especially a kind of disjunctor square steel structure.
Background technique
Steel milling train can be divided into large-scale, the middle-size and small-size and wire mill of beam-and-rail according to its purposes and the specification of producing product.Wherein, beam-and-rail large-sized rolling mills roll nominal diameter is 650-950mm, and the product that is applicable to rolling is: the products such as 80-250mm square-round steels, 38-75kg/m heavy rail, 20-65# I-steel, 16-40# channel-section steel, 16-25# angle steel.
But if adopt beam-and-rail large-sized rolling mills to produce square steel, its fillet is larger, product size precision is lower, conventionally can only produce for machining, forge the raw material of processing.For the following square steel of 80mm, adopt beam-and-rail large-sized rolling mills to produce uneconomical, therefore, there is no at present the related art scheme of utilizing beam-and-rail large-sized rolling mills to produce the following square steel of 80mm.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of disjunctor square steel structure that can utilize beam-and-rail large-sized rolling mills to produce the following square steel of 80mm.
The technical solution adopted for the present invention to solve the technical problems is: disjunctor square steel structure, comprise the Fang Gang that even number connects successively, a seamed edge of one of them Fang Gang is connected with a seamed edge of another Fang Gang by the firm changeover portion in side, and the axisymmetric center line of all Fang Gang is positioned at same plane.
Further, Fang Gang and another Fang Gang are mirror image symmetry with the symmetry plane between two Fang Gang.
Further, comprise that two other foreign side is firm, described Fang Gangjun Liang Ge foreign side just between, described Liang Ge foreign side is mirror image symmetry with symmetry plane just.
Further, the thickness range of the firm changeover portion in side is 5～10mm.
The invention has the beneficial effects as follows: when actual fabrication, first rectangular bloom is heated to 1200 ℃ of left and right, the milling train being sent to disjunctor pass is rolled.After the mill milling of the disjunctor pass with described disjunctor square steel structure matching, form the product of disjunctor square steel structure.The present invention is by the square steel product of design linking body structure, can allow the square steel product of a plurality of disjunctors of the direct disposable production of disjunctor pass of beam-and-rail large-sized rolling mills, greatly improved manufacturing efficiency, also takes full advantage of this equipment of beam-and-rail large-sized rolling mills.The present invention can be for utilizing beam-and-rail large-sized rolling mills to make the square steel of the middle small dimension below 80mm.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure, be labeled as: the square steel product 1 of linking body structure, Fang Gang11, foreign side are firm 12, side just firm 15, the symmetry plane 2 of changeover portion 13, Fang Gang14, foreign side, thickness s.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Disjunctor square steel structure as shown in Figure 1, comprises the Fang Gang that even number connects successively, and a seamed edge of one of them side firm 11 is connected with a seamed edge of another side firm 14 by the firm changeover portion 13 in side, and the axisymmetric center line of all Fang Gang is positioned at same plane.
Disjunctor square steel structure is the structure of the square steel product 1 of the linking body structure in Fig. 1, applies this structure, can guarantee that beam-and-rail large-sized rolling mills is by the square steel product 1 of the direct disposable production linking body structure of disjunctor pass of large-sized rolling mills.Square steel product 1 for linking body structure, it comprises the side firm 11 that even number connects successively, when firm changeover portion 13 general sides, side firm 11 have been connected with side firm 14, the disjunctor pass cutting-in chock that need to guarantee large-sized rolling mills is not fractureed, therefore in conjunction with practical experience, side just changeover portion 13 generally chooses comparatively mild transient mode for best, and two sides firm 11 of symmetry plane 2 both sides can not be too approaching, and mild transition be take as best in side just changeover portion 13.
The demand that needs the Fang Gang that a plurality of Dimensionss of disposable production are identical for some, can select such scheme: side firm 11 and another side firm 14 are mirror image symmetry with the symmetry plane 2 being positioned between two Fang Gang (11,14).So only the disjunctor pass of large-sized rolling mills need be made as to the identical disposable firm product in right side that is produced into that gets final product.
In order further to allow just product of the more side of the disposable production of large-sized rolling mills, can select such scheme: comprise two other foreign side just (12,15), described Fang Gang (11,14) is all positioned between Liang Ge foreign side firm (12,15), between described Liang Ge foreign side firm (12,15), with symmetry plane 2, is mirror image symmetry.Firm 15 by respectively increase Gang12He foreign side of foreign side outside firm 14 in side firm 11 and side, can allow four firm products in side of the disposable production of large-sized rolling mills, greatly improved manufacturing efficiency.
For the separation in the firm product in side later stage of guaranteeing to be connected, taking into account again to produce between the firm product in time side has good Placement, and thickness s scope that can the firm changeover portion 13 of selecting party is 5～10mm.In conjunction with practical experience, when thickness s scope is 5～10mm, not only can well connect the firm product in adjacent side, also allow the later stage in separation side, be convenient to during firm product process.
