From April 5th to 15th, 2011, Shougang Jingtang Company's 2250 hot rolling underwent a 10 day shutdown and annual maintenance. Shougang Construction Group completed 151 equipment maintenance tasks for the entire rolling line, including slab storage, heating furnace area, rough rolling area, precision rolling area, curling machine area, and steel coil storage, as scheduled, smoothly, safely, and with high quality. At 23:58 on April 13th, the first hot-rolled plate after annual maintenance was produced one day ahead of schedule, and Shougang Jingtang Company successfully completed the 2250 hot-rolled annual maintenance.

        The implementation of the 2250 hot rolling annual repair project at Shougang Jingtang Company fully proves that Shougang Construction Group has the ability to carry out annual repairs on the entire hot rolling strip production line, and can provide high-quality and efficient services to the owner units.
