Embodiment 1
[0019] The thickness of the steel plate in this embodiment is 16mm, and it is composed of the following components in weight percentage: C: 0.10%, Si: 0.5%, Mn: 0.57%, P: 0.003%, S: 0.001%, Cr: 9%, Mo : 1.05%, Cu: 0.04%, Ni: 0.06%, Sb: 0.003%, Sn: 0.005%, As: 0.009%, and the balance is Fe and unavoidable impurities.
[0020] The production method of the high chromium steel plate in this embodiment includes a smelting die-casting process, a heating and rolling process, and a heat treatment process, and the steps of each process are as follows:
[0021] (1) Smelting and die-casting process: use electric arc furnace or converter to smelt, then send it to LF refining furnace for refining and vacuum treatment, and then cast steel ingots through die-casting operation;
[0022] (2) Heating and rolling process: the steel ingot is heated and rolled in a soaking furnace, and the heating and heat preservation are uniform. The hot rolling process is adopted. The temperature of the steel i...
