What is extra thick steel plate?

Extra thick plate refers to the steel plate with a thickness specification of more than 60mm. The production characteristics of the extra thick plate are as follows: the ingot is mainly used as raw material, some of which are forged billets or welded composite billets. The production of the ingot is basically combined with LF, VD, RH and other furnace refining means, and the casting of the ingot is carried out by the technology of directional solidification and electroslag remelting.

The mill is equipped with vertical roll mill, hydraulic AGC and roll bending device to improve the shape, edge quality and rolling accuracy of the steel plate. The back of the production line is equipped with a variety of annealing, tempering and tempering equipment, in order to meet the requirements of steel plate variety, high performance, low stress.

The main specifications of the panels for thermal power generation are 90mm, 95mm, 110mm, 125mm, 135mm, 145mm, 178mm, 200mm, 215mm, 240mm, 270mm in thickness. The width of 3300 ~ 3900 mm.
