Embodiment

[0037] see figure 1 , the present invention is a steel rolling production process applied in steel production, the rolling steel produced by extruding metal between rolls to make it plastically deformed, its technological process is: billet preparation, billet heating and tapping, steel rolling, Finishing and warehousing; in the present invention, the purpose of billet heating is to improve plasticity and reduce deformation resistance, so as to facilitate rolling. In the rolling of steel, the steel billet is rolled by a two-roll mill, which adopts a continuous configuration, and its productivity and quality are superior to other methods. Among them, the type of rolled steel is HRB335 among the hot-rolled ribbed steel bars for reinforced concrete, with specifications ranging from Φ10mm to Φ25mm. It is the most common construction steel in China at present. Steel conforming to GB1499.2-2007. In this embodiment, the longitudinal hot rolling adopted for steel rolling, that is, w...

Abstract

The invention discloses a steel rolling production process used in steel production, which comprises the following process flow: blank preparation, blank heating and steel tapping, steel rolling, finishing and warehousing; the steel rolling comprises the following steps: (1) test-rolling proof rolling; (2) checking a roller and replacing a groove; (3) guide installing; (4) rolling mill adjusting;(5) intermediate top cropping and end shearing, and carrying out finishing and shearing on billet after steel tapping by shearing equipment. In the invention, a double-roller rolling mill is used forrolling the billet, and a groove rolling method is also used with less product categories, thus being in favor of improving production technical level and performing professional strengths thereof, saving energy resource, reducing environmental pollution, effectively improving utilization ratio of equipment and production efficiency of steel rolling, and having the advantages of small production investment, simple process, low cost, high yield and energy saving and emission reducing, which is applicable to large-scale integrated production.

Description

Technical field: [0001] The present invention relates to a process flow, in particular to a steel rolling production process applied in steel production. Background technique: [0002] Steel rolling refers to the pressure processing process in which metal is compressed by rotating rolls to produce plastic deformation. The purpose of steel rolling is, on the one hand, to obtain the required shape of steel, and on the other hand, to improve the internal quality of steel and improve the mechanical properties of steel. [0003] Rolling production process (rolling production process now) is the combination and sequence of a series of processes required to roll a steel sharp or a billet into a steel with a certain shape, size and performance. Rolled products are different, and the production process is also different. The formulation of the steel rolling production process is one of the important items in the design of the steel rolling workshop. At present, the steel rolling p...
