| titleOfInvention | A kind of manufacturing method of stainless steel |
| abstract | The invention discloses a manufacturing method of stainless steel, which comprises a furnace shell, a furnace chamber, an air inlet part arranged on the furnace chamber, an opening on the furnace shell matched with the air inlet part, and an opening matched with the air inlet part. an air inlet pipe; a connection cavity is arranged on the air inlet part, and an air inlet is arranged at the bottom of the connection cavity; a seal is arranged in the connection cavity, and a first seal is arranged between the seal and the bottom surface of the connection cavity A sealing layer, a second sealing layer is provided between the sealing element and the air intake pipe. In the present invention, through the cooperation between the sealing element, the first sealing layer and the second sealing layer, the sealing cooperation between the air inlet pipe and the connecting cavity is effectively realized, so as to ensure that there is no air leakage between the two, and realize the furnace chamber. The interior is always kept in a vacuum state to achieve degassing and refining of the molten material in the furnace. |
