Description

Binary alloy eutectic melting crucible

The technical field is as follows:

the invention relates to the field of test equipment for metallurgy, material forming and casting, in particular to a binary alloy eutectic melting crucible.

Background art:

in the process of preparing the binary alloy by melting the two pure metals, the phenomenon that the melting point of the alloy is lower than that of the pure metal is difficult to directly observe in the experimental process. The magnificent person has designed a quartz observation crucible (CN 201020135929.2) for high temperature observation melting furnace, and its crucible arm bottom is equipped with the observation window that the light transmissivity is good, and its advantage lies in obtaining clear glass batch and melts the image, and the shortcoming is that this crucible will wait to melt the material and place together, can't observe the phenomenon that two kinds of pure metals melt liquid and solid-state coexistence in-process, also can't measure the eutectic temperature that two kinds of pure metals constitute the alloy. It can be seen that at present, it becomes a realistic demand in the market to provide a device for observing binary alloy eutectic melting and measuring eutectic point temperature in a laboratory.

The invention content is as follows:

the invention provides a binary alloy eutectic melting crucible for overcoming the defects in the prior art.

The application provides the following technical scheme:

a binary alloy eutectic melting crucible, which comprises a main body and is characterized in that: the induction heating device comprises a main body, a cover, a groove body, an induction coil and an induction current control device, wherein the main body is provided with the corresponding matched cover, the cover is provided with the groove body, the groove body is a V-shaped groove, the bottom of the groove body is provided with a long hole, and the main body is sleeved with the induction coil which is communicated with the induction current control device; the induction coil is made of a hollow copper tube and distributed spirally, a cooling water inlet is arranged at one end of the induction coil, and a cooling water outlet is arranged at the other end of the induction coil.

On the basis of the technical scheme, the following further technical scheme can be provided:

the cap outside the tank body is provided with a circle of flanging, and a mounting groove which is in splicing fit with the main body is formed through the flanging and the outer wall of the tank body.

The main body is a barrel-shaped structure with the lower end sealed and the upper end opened.

The invention has the advantages that:

the invention has simple structure and convenient use, can measure the eutectic temperature in real time, can observe and observe the eutectic melting of the binary alloy, and fills the blank in the prior experiment.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic perspective view of the cap of the present invention;

fig. 3 is a schematic perspective view of the cap in another direction.

The specific implementation mode is as follows:

as shown in fig. 1-3, a binary alloy eutectic melting crucible comprises a main body 1, wherein the main body 1 is a cylindrical structure with a lower end sealed and an upper end opened. Be equipped with cap 2 in main part 1 upper end, cap 2 on be equipped with

cell body

3, 3 outer walls of cell body are the round platform form to one section distance of 2 lower surfaces of protrusion cap is equipped with downward round turn-ups 2a on the outer disc of cap 2, and is formed with through turn-

ups

2a and 3 outer walls of cell body and forms grafting complex mounting groove 2b with 1 upper end opening part of main part.

The inner groove wall of the groove body 3 is an inclined wall, so that the groove body 3 is of a V-shaped groove structure, a long hole 4 is arranged at the bottom of the groove, and the extending direction of the long hole 4 is the same as that of the groove body 3. So that the molten metal can rapidly flow into the body 1 through the elongated holes 4.

The outer side of the main body 1 is further sleeved with an induction coil 5, the induction coil 5 is made of a hollow copper tube and is spirally distributed on the outer side of the main body 1, and the surface of the induction coil 5 is communicated with an induction current control device through a lead (not shown in the figure). A cooling water inlet 5a is provided at one end of the induction coil 5, and a cooling water outlet 5b is provided at the other end of the induction coil 5.

The working process is as follows:

firstly, the cap 2 is placed on the main body 1, then the main body 1 is inserted into the induction coil 5, then a metal plate for experiment is respectively placed on the inner groove walls of the two sides of the groove body 3, and the lower ends of the two metal plates are firstly mutually contacted. The induction current control device controls the alternating current with a certain frequency to be introduced into the induction coil 5, so that an alternating magnetic field with the same frequency exists around the induction coil 5, and induction current (eddy current) with the same frequency is generated for the two metal plates on the cap at the inner side of the induction coil 5. Due to the skin effect and the heat effect of the induction current, the contact positions of the two metal plates are rapidly heated, meanwhile, the temperature in the crucible is slowly heated upwards, when the temperature is raised to the state that the two metal contact surfaces are in a liquid state, namely, the eutectic temperature is reached, the induction current control device is maintained, the temperature in the crucible is not raised, the eutectic temperature can be measured at the moment, meanwhile, the pure metal in the main body 1 is observed to be in a solid state, the position where the two metals are in contact forms alloy liquid, the alloy liquid is dripped into the cylindrical crucible from the long-strip hole, and then the temperature in the crucible is kept.
