[0017] The present invention will be further described below in conjunction with the examples.
[0018] A water-cooled die-casting production process for high-demand die steel P80 medium-thick plate slabs, the production process adopts argon protection pouring in the whole pouring process to isolate the contact with the air after the molten steel flows out from the nozzle during the pouring process; The solid mold slag is used to protect the casting to ensure the surface quality of the slab; the rising hole of the convection steel is adjusted to make the molten steel rise smoothly in the water-cooled die casting to ensure the surface quality of the slab; the details are as follows:
[0019] In the whole pouring process, argon gas protection is used for pouring, figure 1 It is a schematic diagram of the argon protection casting adopted in the present invention. The pouring device consists of an argon gas group 1, an argon gas pipeline 2, a double argon blowing ring 3 and a sea...
