Casting process of high-manganese steel lining plate used in as-cast state

The invention relates to the related technical field of machining, in particular to a casting process of a high-manganese steel lining plate used in an as-cast state, and the casting process comprises the following steps: S1, designing chemical components of the high-manganese steel lining plate and preparing raw materials; s2, modeling design of the high-manganese steel lining plate: brushing a magnesia powder coating on the surface of sodium silicate-bonded sand twice, adopting an insulated riser, and coating sand on the outer side of the external chill with the thickness of 8-12mm; s3, smelting and pouring chemical components of the high-manganese steel lining plate: firstly putting the steel ingot into molten aluminum for smelting, then putting ferromanganese and precious alloy materials into a smelting furnace by using a feeding device, and finally adding trace elements, according to the casting method and the feeding device, it can be guaranteed that the five main raw materials including the high-carbon
