Description
Technical field:
This utility model relates to a kind of continuous casting of titanium-nickel alloy graphite mold.
Background technology:
Casting is the casting method of a kind of advanced person continuously, its principle is by melted metal, constantly pours in a kind of particulate metal type being called crystallizer, solidifies the foundry goods of (crust), continuously pulling out from the other end of crystallizer, it can obtain the foundry goods of arbitrarily long or specific length.But owing to the chemical property of Ti-Ni alloy is active, at high temperature reacts with most refractory material and be difficult to melting and molding, produce Ti-Ni alloy at present both at home and abroad and mostly adopt molding-peeling-rolling mill practice.Adopting the ingot casting after the method molding have to remove its rising head and top layer defective part, therefore the loss of metal is big, and processes loaded down with trivial details, considerably increases the cost of Ti-Ni alloy.By casting the trend replacing conventional die castings to be the research of current Ti-Ni alloy continuously, the forming process of casting mainly completes in a crystallizer continuously, crystallizer is the core component of continuous casting system, and its effect is to be formed with the continuous casting green shell determined shape, have some strength.
Summary of the invention:
The purpose of this utility model is to provide a kind of continuous casting of titanium-nickel alloy graphite mold being obtained in that any surface finish.
Above-mentioned purpose is realized by following technical scheme:
A kind of continuous casting of titanium-nickel alloy graphite mold, its composition includes: cooling jacket, described cooling jacket has through hole, described through hole connects water-cooled copper wall, described water-cooled copper wall connects graphite crystallizer overcoat, described graphite crystallizer overcoat connects boron nitride liner, and described boron nitride liner connects lime crucible, and described lime crucible coordinates heat induced coil to use.
Described continuous casting of titanium-nickel alloy graphite mold, the bottom of described lime crucible has connection through hole, the described through hole that connects connects the top of described boron nitride liner, described graphite crystallizer overcoat connects sealing ring gland, equipped with sealing ring between described graphite crystallizer overcoat and described sealing ring gland, described sealing ring is contained in the notch of the lower end of described water-cooled copper wall, the inside of described boron nitride liner, equipped with dummy bar, takes up alloy melt in described lime crucible.
Described continuous casting of titanium-nickel alloy graphite mold, the bottom side of described cooling jacket has cooling water inlet, described cooling water inlet connects cooling water inlet pipe, and the bottom opposite side of described cooling jacket has coolant outlet, and described coolant outlet connects cooling water outlet pipe.
Beneficial effect:
1. this utility model achieves the purpose utilizing Ti-Ni alloy rod base that continuous casting obtains any surface finish, owing to metal is rapidly cooled, and compact crystallization, even tissue, better mechanical property.
2. during the work of this utility model graphite mold, vacuum can reach 10-2Pa, can increase substantially Ti-Ni alloy casting quality.
3. this utility model is without the rising head of running gate system, and ingot casting truncates without crop when rolling, has saved metal, has improve recovery rate.
4. this utility model achieves the continuous casting production of Ti-Ni alloy, exempts moulding and other operation, alleviates labor intensity, improve production efficiency.
5. being completely embedded between parts of the present utility model, coordination, good seal performance.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of this product.
