Problems solved by technology

[0004] like figure 1 Shown is a schematic diagram of the pass pattern of a traditional typical two-roll mill for rolling round steel. During two-roll rolling of round steel, the elliptical or round pass system composed of two rolls continuously deforms the rolled piece. In the last rolling stand The final circular section is rolled through a circular hole, and there are disadvantages such as low dimensional accuracy, large internal stress of the rolled piece, low product yield, small single-pass elongation coefficient, large rolling load, and low production efficiency.
[0005] like figure 2 Shown is a schematic diagram of the pass pattern of a traditional typical three-roll mill for rolling round steel. When rolling round steel by the three-roll method, on the basis of the two-roll rolling round steel, the final rolling is formed by three rolls. The circular pass deforms the rolled piece and rolls out the final circular section. This rolling process improves the shortcomings of the two-roll mill to produce round steel to a certain extent in the final rolling forming stage, but it cannot eradicate the defects of the two-roll and three-roll rolling mills. Insufficient round steel production, and when rolling round steel with three rolls, the transmission system of the rolling mill becomes very complicated. The transmission rolls are "Y"-shaped and "120° angle equally divides the transmission direction", which reduces the transmission efficiency and increases equipment maintenance. The rolling load is further increased, and the three-roll rolling method cannot produce ribbed threaded steel bars

Abstract

The invention discloses a round steel all-purpose method rolling technology, comprising the steps that raw blanks are rolled into round blanks with middle fracture surfaces in a rough rolling unit; and the round blanks with the middle fracture surfaces are subjected to all-purpose method continuous rolling deformation or all-purpose method reciprocating rolling deformation for no less than two passes to be rolled into round steel products. By using the round steel all-purpose method rolling technology, the product size precision can be obviously improved, the problem that the out-of-roundness of the round steel products is severer is solved, the production specification ranges of smooth round bars and deformed steel bars are widened, the deformation of each pass is improved, the rolling deformation pass is reduced, the production efficiency is improved, the surface quality of rolled round steel is improved, the internal stress of rolled pieces after rolling is improved, the product yield is improved, and the rolling load, the production energy consumption and the production cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of metal rolling, and in particular relates to a universal rolling process of round steel. Background technique [0002] In the field of steel products and long products, round steel products mainly include smooth round bars and threaded steel bars. Among them, smooth round bars have a circular cross-sectional shape and are mainly used in machinery, automobiles, transportation, construction and other fields, while threaded steel bars Bars are ribbed steel bars formed by round bars with ribs all over the surface, often used in the construction industry. [0003] At present, the main technological process of round steel rolling: raw material-heating-rough rolling-intermediate rolling-finish rolling-reduction and sizing rolling-cooling-cutting to length-inspection-collection and warehousing, the existing smooth round bar rolling Most of the production lines are made into cross-section round steel through the r...
