Introduction of WQ960E Steel Plate
WQ960E steel plate is a low alloy tempered high strength steel plate. With the large-scale and light weight of heavy machinery in China, the market demand for low-alloy high-strength steel is increasing, especially for high-grade quenched and tempered high-strength steel. The requirements for weldability, low-temperature toughness, shape and surface quality of steel plate are also increasing. In order to meet the market requirements, Wugang imported equipment from Germany and successfully developed WQ960E low alloy quenched and tempered high strength steel, which filled the gap in high-grade quenched and tempered high strength steel, and accumulated experience and necessary technical reserves for later production of higher-grade quenched and tempered steel.

IV. PRODUCTION TECHNOLOGY OF WQ960E STEEL PLATE
Production process: electric furnace smelting LF refining vacuum treatment continuous casting (die casting) cleaning heating controlled rolling flapping inspection shot blasting quenching tempering flapping inspection cutting sampling performance testing storage.
Smelting process: In the process of smelting, the chemical composition of steel and the removal of harmful elements are strictly controlled. In order to further improve the weldability, cold bending property and toughness of steel plate, especially the low temperature toughness, and minimize the carbon content in steel, the middle and lower limits of the specified carbon content are adopted. The production technology of clean steel, such as refining outside furnace, VD vacuum treatment and calcium treatment, can reduce the content of harmful gases and inclusions in steel, further play the role of rolling control, and achieve ideal results. In order to ensure the effective B content in steel, the molten steel should be deoxidized well and Ti content is certain before adding B, so as to improve the yield of B.
