Mishra Dhatu Nigam Limited (MIDHANI), Hyderabad, India, awarded two contracts to Danieli for design, manufacture, supply and installation of a complete, modern plate mill complex consisting of wide plate rolling mill and a modern plate treatment and finishing. 

The new wide plate mill will be able to process metal plates up to 3100 mm wide in a large range of special alloys, including titanium, super-alloys stainless steel, HSLA steels, etc. A walking hearth-type reheating furnace will reheat the input slabs for rolling in the plate mill.

The single-stand plate mill will be able to withstand a maximum roll separating force of 60,000 kN and will be designed with the most modern technological features, to produce high-quality plates in regard to dimensional accuracies as well as defect-free surfaces.

Plate treatment and finishing facilities will consist of a dividing crop shear, plate leveler, roller hearth furnace and a continuous roller pressure-quenching machine. 

The leveler will operate with 11 rolls, suitable for processing the plates ranging from 5 to 50 mm thickness in hot and cold conditions. Heat treatment will be done at the roller hearth furnace and a new generation high-efficiency continuous roller pressure quenching machine.

Electrical and automation systems for the entire plate mill complex will be supplied by Danieli Automation. Reheating and heat treatment plants from Danieli Centro Combustion.

Production for the first plates is scheduled by the second half of 2019.
