Problems solved by technology

However, in the production of large and super-shaped H-beams, it is necessary to use two two-roll reversible billet mills and 10-12 CMA universal rolling mills as the semi-continuous rolling form of continuous rolling for finishing rolling to meet the needs of large and super large The rolling requirements of H-shaped steel and the increase in the number of finishing rolling units lead to an increase in the total investment in equipment

Abstract

The invention provides a rolling process of large and ultra-large H-shaped steel. The rolling process is suitable for large and ultra-large H-shaped steel continuous rolling production lines, can realize ordinary reversible cogging and large rolling reduction reversible cogging of a CMA universal rolling mill of large H-shaped steel, reduces the number of finishing mill units, and reduces the total investment of equipment.

Description

technical field [0001] The invention relates to a rolling process of large steel, in particular to a rolling process of large and super large H-shaped steel. Background technique [0002] In recent years, as the state has continuously increased the control of energy conservation and emission reduction in the steel industry, it has had a great impact on the steel industry. Some small and medium-sized steel factories have closed down one after another, and the requirements for newly built steel factories are getting higher and higher. Steel mills have launched some high value-added products. Steel sheet piles and H-beams, as high value-added steel products, have been paid more and more attention by steel mills, and steel sheet piles and H-beam production lines have been launched one after another to roll steel sheet piles and H-beams. In the traditional rolling of small and medium-sized H-beams, one or two two-roll reversing mills or three-roll reversing mills are often used ...
