| description | The invention discloses a new material for hot rolling seamless steel tube steel balls, which comprises 3.0 percent to 4.1 percent of C, less than or equal to 1.2 percent of Si, 20 percent to 39 percent of Cr, 1.7 percent to 3.0 percent of Ni, 0.25 percent to 0.8 percent of Mn, and the balance of Fe. A preparation method of the hot rolling the seamless steel tube steel balls comprises: firstly, combining molding sand after molding to be made into an integral sand model, and installing the integral sand model on a centrifugal casting machine for casting; secondly, adding furnace charge in a middle frequency furnace for being melted into molten iron, and continuously heating after melting so as to perform degassing and modificating treatment on the molten iron; thirdly, deslagging the molten iron and pouring the molten iron into a casting ladle for secondary deslagging; scattering deslagging agent on the surface of the molten iron and pouring the molten iron into the sand model for molding by casting through th |
