Abstract

The invention discloses a fully-closed argon protection device. The fully-closed argon protection device comprises a steel ladle and a funneled brick; an argon protection ring is fixed to the lower portion of the steel ladle and comprises an upper ring piece and a lower ring piece which are fixed together with screws; a refractory material cylinder is connected to the bottom of the lower ring piece in a sleeving mode, and the funneled brick is sleeved with the bottom of the refractory material cylinder; a plurality of vertical argon jetting holes are formed in the lower ring piece annularly, and argon pipes are connected with the argon jetting holes; an annular fire-retardant elastic piece is arranged on the top of the refractory material cylinder; two elastic metal rings are arranged in the annular fire-retardant elastic piece concentrically; a plurality of conical sleeves are connected between the two elastic metal rings; and thread sleeves in one-to-one correspondence with the conical sleeves are arranged at the bottom of the annular fire-retardant elastic piece and internally connected with adjusting bolts in a threaded mode, and the adjusting bolts and the conical sleeves makeselective contact. The defects in the prior art can be improved, and the universality of the protection device is improved.

Description

technical field [0001] The invention relates to the technical field of die casting steel ingot pouring, in particular to a fully enclosed argon gas protection device and a protection method thereof. Background technique [0002] During the pouring process of the die-cast ingot, there is a 150-200mm bare molten steel pouring section between the ladle drain and the middle-injection pipe brick. During the molten steel pouring process, the contact between the molten steel and the air may easily cause secondary oxidation of easily oxidizable elements in the steel. Oxidation, the design of the die-casting argon protection device can isolate the molten steel from the air and play a role in protecting the pouring. Chinese invention patent CN104107887 B discloses a pouring protection device and method for casting and pouring, which can effectively control the argon flow during the casting and pouring operation, avoid secondary oxidation of molten steel, and at the same time do not af...
