In terms of direction is concentrated mainly on preparation, performance and stability, and its preparation method is mainly inhaled using copper mold vacuum
Casting.Preparing the method that bulk amorphous alloys are most universal, most practical is exactly vacuum suction casting technique.This method one advantage of maximum is
Governing factor is fewer in its technical process, only melt temperature, suction velocity etc., so block can be prepared to relative ease
Amorphous alloy.Its technical process prepared is: firstly, melt chamber is evacuated, and in the feelings for being filled with argon gas and doing protective gas
Under condition, melted using the method for electric arc melting by intact master alloy is configured, to repeat to melt 3-5 times, after its fusing uniformly,
Molten master alloy is sucked copper mold by the draught head for recycling the generation between melt chamber and copper mold；Due to copper mold and its outside
Great cooling rate is generated under the collective effect of recirculated cooling water, so that liquid master alloy cools down rapidly, thus to prepare
Required bulk amorphous alloys.
However, when the copper mold vacuum suction casting technique used in us prepares bulk amorphous alloys at present, the spiral shell of copper mold bottom processing
Cooperation between pit and screw so that frequent some problems in use, such as: when threaded hole and screw interference or mistake
When crossing cooperation, inhale during casting can due to ventilate it is unsmooth and lead to problems such as liquid master alloy fill type is imperfect or village hollowing；When
When threaded hole and screw clearances cooperate, if gap is excessive will lead to suction casting during screw be easy to fall off, in this way may material leakage
Cause to inhale casting line clogging, so that equipment damage or gas leakage are serious, and can adding to us when gap is proper
Work requires to increase certain difficulty.
It is set not only to be able to maintain the good ventilation anti-leak-stopping of energy again during inhaling casting in conclusion how to provide a kind of copper mold
