[0002] Wear-resistant alloy cast balls are the crushing media in the ball mill, used to crush the materials in the mill. There are two common forms of alloy cast balls, one is a cast grinding ball made of chromium alloy cast iron, and the other is a cast grinding ball made of ductile iron. When manufacturing alloy cast balls, usually a variety of metal raw materials are first melted into molten steel, and then the molten steel is injected into the mold, and then taken out of the mold after it cools down, thus completing the casting.

Moreover, the temperature of the molten steel will gradually decrease over time, which will affect the fluidity of the molten steel and thus have an adverse effect on the casting process.

[0023] according to Figure 1-Figure 4 As shown, a device for preparing alloy cast balls includes a processing table 1, a mounting bracket 2 is fixedly installed on the upper end of the processing table 1, an alloy casting mechanism 3 for continuous casting of steel balls is provided on the mounting bracket 2, and an auxiliary cooling mechanism 4 for air blowing cooling is movably installed below the alloy casting mechanism 3.

[0024] Specifically, the alloy casting mechanism 3 includes a feeding platform 301 detachably mounted on the upper end of the mounting bracket 2, a cylindrical ladle 302 is fixedly mounted on the lower end of the feeding platform 301, a feeding funnel 303 is arranged on the upper end of the feeding platform 301, a heating sleeve 304 is sleeved on the outer side of the cylindrical ladle 302, a discharge assembly 305 is fixedly mounted on the lower end of the cylindrical ladle 302, and a control panel 306 for adjusting the output power of the heating sleeve 304 is arranged on the upper end of the feeding platform 301. Before the casting starts, the staff will first add the molten steel formed after smelting to the interior of the cylindrical ladle 302 through the feeding funnel 303, and then the heating sleeve 304 will automatically heat and keep the molten steel warm, thereby improving the fluidity of the molten steel.

[0025] Specifically, the auxiliary cooling mechanism 4 includes a rotating disc 401 movably mounted on the processing table 1, a driving motor 402 for driving the rotating disc 401 is fixedly mounted at the lower end of the processing table 1, a plurality of spherical molds 403 are arranged at equal intervals on the rotating disc 401, the spherical mold 403 includes an upper mold shell and a lower mold shell, the lower mold shell is fixedly connected to the rotating disc 401, a casting port is arranged on the outer side of the upper mold shell, after the control valve is opened, molten steel will enter the interior of the spherical mold 403 through the discharge pipe and the casting port, and the rotating disc When 401 rotates, the spherical mold 403 will rotate synchronously, so that multiple spherical molds 403 are transported to the bottom of the discharge assembly 305 in sequence.
