Each heavy-plate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.
HBI is a low-carbon raw material used for steel production in electric furnaces and generates up to 50% less CO 2 (scope 1 + scope 2) than the traditional blast-furnace method. The contracted plant can be converted to use up to hydrogen as a reducing agent, which makes possible further reduction of CO 2 emissions.
Feb 06, 2012· A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Read More

In this method, the steel is heated locally by a pressurised mixture of oxygen and a combustible gas such as propane, which passes through a ring of small holes in a cutting nozzle. The heat is focussed on to a very narrow band and the steel melts at 15000 C when a jet of high-pressure oxygen is released through a separate hole in the centre of the
