Embodiment 1
[0018] Casting method of tooth plate in this embodiment
[0019] (1) Melting process of the matrix part
[0020] The material of the base part is composed of the following chemical composition in weight percentage: C 1.15%, Mn 17%, Si 0.6%, Cr 1.6%, Mo 0.5%, Ti 0.06%, RE 0.3%, S 0.03%, P 0.06%, The balance is Fe and unavoidable impurities. The smelting process includes the following steps: Add 2% bottom slag material at the bottom of the smelting furnace. The composition and weight percentage of the bottom slag material are: lime 80%, fluorite 20% ;Return to the furnace ultra-high manganese steel and carbon scrap steel ingredients, ferromolybdenum is added with the furnace charge according to the calculated amount, when the temperature reaches 1550 ° C, add electrolytic manganese, ferrochrome and ferro-titanium after drying according to the calculated amount, when the temperature is 1500 ° C, Carry out final deoxidation; the steel slag is mixed out, the ladle is cleaned in ad...
