摘要： The present invention discloses a vacuum coating device, comprising: a crucible; an induction heater provided on the periphery of the crucible; a flow distribution box connected to the top of said crucible via a steam pipe. Wherein said flow distribution box is provided inside with a horizontal pressure stabilizing plate, said flow distribution box is connected on the top with a nozzle, said steam pipe is provided with a pressure regulating valve, and said pressure stabilizing plate has a multi-hole structure. The lower surface of said pressure stabilizing plate is connected to a horizontal flow suppression plate, and a space is formed between the side of said flow suppression plate and the inner wall of said flow distribution box. A jet moderating zone is formed between the joint where said flow distribution box and said steam pipe are connected and the lower surface of said pressure stabilizing plate, and a jet accelerating zone is formed between the upper surface of said pressure stabilizing plate and the joint where said flow distribution box and said nozzle are connected. When the high-temperature steam reaches the low-temperature steel plate, a uniform coating can be formed on the steel plate surface.

摘要： A method for continuous thin strip casting comprises: introducing molten steel through a long nozzle (11) into a tundish (1) from a ladle (10), and heating the molten steel in a manner of externally heating the tundish, so as to maintain the molten steel at a basically constant temperature in an entire pouring process. The tundish is one strand tundish, and the molten steel flows below a weir (2) which is located at one side in the tundish, then passes a first dam (3) and enters a channel (4) with an induction heating device, and a temperature of the molten steel after induction heating is 30˜50 C higher than that of the molten steel introduced into the tundish, and the heated molten steel then flows out from a outlet at the other side of the tundish to a nozzle (5) for casting. The present invention has also provided a device for continuous thin strip casting, which can realize constant-temperature pouring of continuous thin strip casting, which may overcome quality difference of rolls before and after, stabilize both the pulling speed of the strip and the condition of the molten pool, and thus avoid quality defects caused by speed changes. It can also fully facilitate the inclusions in the molten steel to float upwardly, so as to improve quality of the cast strip; reduce the superheat degree of the ladle molten steel to lower the consumption of energy, improve the quality of the molten steel and decrease the wastage of refractory material; and lessen the formation of the cold steel on the surface of the molten pool at the preliminary stage of pouring, so as to facilitate it entering into the normal pouring stage immediately.
