OREANDA-NEWS. October 25, 2011. The Plate branch of Wisco hot rolling central plant successfully finished the first round trial production of Q420GJC plate used for high-rise building with 100% acceptability just in one time, reported the press-centre of Wisco.

Since this year, plate plant actively organized trial-production for new product and strived to exploit new market. Q420GJC plate, developed aiming at demand by high-rise building market, awarded its contract for first batch to Wuhan city key project of Zhangzhidong Museum.

By owing well strength, low yield-tensile ratio and welding performance, Q420GJC plate is in integrated use at key bearing parts of the project. In order to ensure execution of the contract, the plate plant conducted whole process tracing from slab entering till products delivering, enhanced design optimization on rolling process and controlled cooling model, as well as adjusted process parameters according to site equipments and controlling situation, and by means of increasing rolling passes and lowering temperature before aligning, assured products’ performance and appearance.
