Iron & Steel Making Components
The iron and steel making components provided by Doosan Heavy Industries & Construction include forging rolls, core components of rolling mills required for manufacturing thick plate or hot/cold rolled coil, and mill housing, a large structure that supports the rolls used in the streamlining rolling process.
A rolling mill is a machine tool that passes heated or normal-temperature metal through two rolls and transforms it into diverse shapes. A work roll is a core part of a rolling mill that enters into direct contact with rolling material to make cold rolled carbon sheets (CR) of the desired thickness. Doosan Heavy Industries & Construction provides high quality work rolls of uniform surface hardness in terms of surface and depth, in order to meet the diverse needs of customers.
Back Up Roll
A backup roll is the largest and heaviest roll used in rolling mills, and delivers pressure to and supports the work roll. Doosan Heavy Industries & Construction is capable of producing pure, defect-free materials with advanced steel manufacturing and mold technologies, and applies the Barrel Induction heat treatment method to produce uniform hardness in terms of both surface and depth.
Plate Backup Roll
A plate backup roll is a large item of equipment for rolling thick plate for shipbuilding (generally thicker than 6mm). Doosan Heavy Industries & Construction is capable of producing pure and defect-free materials with advanced steel manufacturing and mold technologies, and boasts superior rolling performance with optimal quality heat treatment.
A mill housing is a large structure that supports the rolls used in the rolling process, and absorbs weight from the process to make the process smooth. Doosan Heavy Industries & Construction has a manufacturing record of up to 320 tons.
It consists of a drive side and work side. A plate moves between the sides to be press rolled. A mill housing is divided into rough mill housing, hot mill housing and cold mill housing depending on the method of rolling. It is also categorized into plate mill housing and universal mill housing depending on the shape of plate produced. The universal mill housing is used to produce section shape steels.
