Abstract

A method and equipment for producing steel semi-finished products. The invention discloses a method and equipment for continuously producing steel semi-finished products. A plurality of bloom strands are continuously produced by casting liquid steel into a plurality of molds using a continuous casting device. Subsequently, the one or more bloom strands are fed in-line to a corresponding rolling mill configured to hot-roll the input continuous casting bloom strands to produce rolled billets.

Description

technical field [0001] The present invention generally relates to methods and apparatus for producing semi-finished steel products. In particular the invention relates to a method and an apparatus for in-line rolling of a steel slab from a continuous casting bloom. Background technique [0002] Rolling mills are installed to produce finished steel products, for example for local markets in developing countries and for adjacent markets for finished steel products such as mild steel bars used in civil construction. In countries with insufficient production of semi-finished (cast) steel products, these mills will typically rely on importing billets from other countries with greater steelmaking capacity and rolling finished products for their local markets. This situation is prevalent in many developing countries due to the scarcity of locally generated scrap and the difficulty of providing a stable and cost-effective electricity supply to operate electric arc furnaces, making ...
