Abstract
The utility model relates to a convenient and easily controlled high vacuum inductive smelting and spray casting device, belonging to the technical field of smelting and spray casting. The convenient and easily controlled high vacuum inductive smelting and spray casting device is characterized in that a nozzle at the bottom of the original quartz tube is extended by a quartz slim tube for linking. The top of the quartz slim tube for linking supports against a spray casting nozzle at the bottom of the quartz tube and has slightly larger diameter than the spray casting nozzle, and the bottom of the quartz slim tube for linking supports against a longitudinal through hole arranged in the upper end of a copper mould and has slightly larger diameter than the longitudinal through hole, thereby preventing the technical problem of low finished product ratio of samples after an alloy melt of the quartz tube is melted due to improper downwards moved position and poor centration of the nozzle and the copper mould and improving the finished product ratio of the samples to over 98 percent from 50 percent in the past.
Description
Technical field
High vacuum melting is inhaled casting process and equipment is widely used in Condensed Matter Physics, the research of Materials Science and Engineering and production field.Especially current by maximum be applied among the specimen preparation of amorphous material.
Background technology
At present, among physics, Materials Science and Engineering field, need prepare in large quantities sample (bar-shaped, tabular, spherical etc.) and carry out scientific experiment and research.Wherein to be equipped with sample be one of scientific methods the most again the most commonly used to the spray to cast legal system.But owing under airtight high vacuum environment condition, carry out the preparation of sample, a real non-easy thing, its process is influenced by several factors and disturbs, temperature as metal bath, the temperature of the jet length of electric current, voltage swing, especially coupon when viscosity, surface tension are difficult to monitoring in time and they with melting alloy melt during with injection, seriously influenced the success rate and the quality of specimen preparation, even can't be shaped at all.
In the technology that adopts high vacuum Medium frequency induction melting spray to cast, present original spray to cast technology and device are to be placed on the quartz glass tube bottom after the alloy raw material that proportioning is good purifies, and this quartz ampoule are placed the central authorities of induction coil.Extracting vacuum, applying argon gas are treated after alloy is melted quartz ampoule to be reduced to the top of die nozzle rapidly together with the alloy that is melted then, carry out injection molding.Commonly used at present is the manual method that descends, and it is to carry out lifting by the rotation of screw thread.Because quartz ampoule will move down and finish injection in the short as far as possible time, so operation easier is bigger, and alloy temperature is difficult for grasping and control, also often is difficult to moulding when filling type owing to nozzle and entrance port centering are bad.The inherent quality that had both influenced coupon also influences the profile filling of coupon.
The problem that the specimen preparation process was common in the past:
1) behind the alloy melting, generally earlier its quartz ampoule is dropped to the mould top as quickly as possible, the about 20-30mm of its stroke carries out spray to cast again.The used time is difficult to control and grasps, and certainly will make one section temperature of alloy melt decline, causes alloy temperature when spraying not reach requirement, influences the coupon inherent quality at last.
2) when quartz ampoule moves down, move down too greatly, will make glass tube nozzle bump mould, cause spray nozzle clogging and distortion, influence the coupon shaping.Move down too for a short time, unsettled distance is excessive, because jet flow is difficult to centering with the entrance port, it is bad to cause alloy melt to charge into mold cavity, influence the coupon shaping, very arrives specimen preparation and fails.
Thereby, how to improve the yield rate and the spray to cast quality of sample, be a long-term insoluble problem of present spray to cast moulding.
The utility model content
The purpose of this utility model is to propose a kind of a kind of high vacuum induction melting-spray to cast device that can greatly improve the sample yield rate.
Of the present utility model being characterised in that contained: induction coil, quartz ampoule, connection are with quartzy tubule, copper mold and alloy melt.Wherein:, and make described quartz ampoule place induction coil coaxially at the built-in described alloy melt in quartz ampoule bottom.
Connect and use quartzy tubule, the nozzle that is positioned at the top withstands on the suction casting nozzle place of described quartz ampoule bottom, and this connection is a bit larger tham the diameter that casting nozzle is inhaled in described quartz ampoule bottom with the diameter of the described nozzle of quartzy tubule.
Copper mold, central authorities have a vertical through hole, and this vertical through hole top peaks at described connection bottom quartzy tubule, and the diameter of described through hole is less than the diameter of described connection with quartzy tubule.
Described connection is 2mm with the minimum of a value of the diameter of quartzy tubule, and maximum is 6mm, and the minimum of a value of length is 30mm, and maximum is 60mm.
The utility model can be increased to 98% to the yield rate of sample from 50%.
Description of drawings

The high vacuum induction melting that Fig. 2 the utility model proposes-spray to cast device schematic diagram:
1, induction coil, 2, quartz ampoule, 3, alloy, 4, copper mold, 5, connect the quartzy tubule of usefulness.
The specific embodiment
Ask for an interview Fig. 1, after the alloy melt fusing, directly the glass tube nozzle of the spray to cast mouth of the quartz ampoule bottom after move down splashes in the copper mold, if pan position is not in place or excessive under the quartz ampoule, not only influence the inherent quality of sample and the profile of sample, also may damage the quartz ampoule nozzle, can't be shaped.
Ask for an interview Fig. 2, after the alloy melt fusing, flow to copper mold exactly with quartzy tubule, be not subjected to air influence midway, also guarantee the smoothness and the flatness of specimen configuration through the connection of guiding usefulness.
The connection that the utility model is used is 4mm with the diameter of quartzy tubule, and length is 40mm.
