| description | The invention discloses a production method for direct casting of cold forging steel. The production method for direct casting of the cold forging steel mainly comprises the steps that the Als content, the aluminum content and the silicon content are controlled in the refining process, the molten steel temperature, the tundish argon blowing flow and the tundish argon blowing time are controlled in the continuous casting process, heat preservation is conducted on molten steel covering in a tundish in the mode that a covering agent and carbonized rice husks are combined, and the molten steel in the tundish is directly cast. And then casting is directly carried out. According to the scheme, other types of steel do not need to be used for molten steel transition of the casting furnace, cold heading steel can be directly adopted for direct casting, transition blanks are avoided, and the production cost is saved.
