The invention provides a method for smelting high-chromium steel, which comprises the steps of: primarily smelting molten iron in a rotating furnace; tapping molten steel after the primary smelting into a steel ladle, adding high carbon ferrochrome in the tapping progress, thus enabling Cr content in the molten steel to reach 1.8-2.4 wt%; refining the steel ladle by an LF furnace, adding low carbon ferrochrome in the steel ladle refining progress by the LF furnace, wherein, on the basis of addition amount of chromium, a weight ratio of the low carbon ferrochrome to the high carbon ferrochromeis (1: 2) to (1: 3.5); and carrying out RH vacuum refining upon molten steel after steel ladle refining by the LF furnace. The invention further provides high-chromium steel smelted by the method forsmelting the high-chromium steel disclosed by the invention. Through the technical proposal, the method disclosed by the invention fully considers the influence to temperature and carbon composition of the molten steel due to addition of chromium alloy, and is good for matching of production rhythm among working procedures, so that production can be carried out smoothly. In addition, through the method disclosed by the invention, yield of the chromium is high, and high-chromium steel with a higher Cr content is obtained in an economical manner.
