Abstract
The utility model relates to a liquid state ball grinder for preparation of intermetalic compound powder, comprising a ball grinding roller, a decelerator, and a speed regulating motor; the outside of the ball grinding roller is provided with a heating device with a temperature controller and a temperature detecting element, and the heating device is an electric furnace with the ball grinding roller therein, and the temperature detecting element is a thermocouple. The utility model is of low cost and simple operation, and can be used for the preparation of series of intermetalic compound powder of various alloy series, particularly for the preparations of high temperature intermetalic compounds that are difficult to prepare by other methods, thus enriching the production varieties of intermetalic compounds.
Description
Technical field the utility model relates to a kind of preparation facilities of intermetallic compound powder.
The background technology intermetallic compound is a kind of one kind of low density, dystectic ordered structure compound between between metal and pottery.Because structural characteristics make it have the unexistent special performance of other traditional material.Because most intermetallic compounds have the room temperature fragility of intrinsic, so obtain that compound-material generally all is to adopt to prepare compound powder between high-performance metal earlier between the high-performance metal of some specific uses, and then, perhaps directly use as requested with powder compacting.This powder adopts traditional fusion casting or powder metallurgic method to be difficult to preparation.
The normally used equipment of preparation intermetallic compound powder is ball mill, its structure mainly comprises motor, reductor, ball grinding cylinder etc., its operation principle is that two or more solid state powder is carried out long-time ball milling or grinding at normal temperatures, make between solid state powder broken repeatedly, cold welding, broken again, finally reach the diffusion of atomic scale and realize alloying, its abrading-ball material generally has chromium steel, stainless steel, carbide alloy, pottery etc., abrading-ball does not participate in reaction in the mechanical milling process, main technologic parameters has the ball grinding cylinder rotating speed, ratio of grinding media to material, the ball milling time etc., mechanical milling process is at room temperature to carry out.The major defect that this equipment prepares intermetallic compound powder is consuming time longer, the energy consumption height, abrading-ball becomes pollution sources easily, and product scope has certain limitation (also finding no intermetallic compound when as present ball milling Ti-Al being generates mutually), particularly can not prepare compound between high-temperature metal.
The summary of the invention technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of liquid ball mill for preparing intermetallic compound powder is provided, its equipment cost is cheap, simple to operate, technology and product are formed controlled, the intermetallic compound powder that can prepare the difference composition of various alloy systems, especially can prepare compound between the high-temperature metal that other method is difficult to prepare, enrich the product category of intermetallic compound.
The utility model solves the problems of the technologies described above by the following technical solutions:
The liquid ball mill of preparation intermetallic compound powder of the present utility model comprises ball grinding cylinder, reductor and buncher, is characterized in: described ball grinding cylinder is outside equipped with heater, and temperature controller and temperature element are housed on it.
Described heater is a resistance furnace, and ball grinding cylinder places in it, and described temperature element is a thermocouple.
The turning cylinder of described ball grinding cylinder is provided with intercommunicating pore, communicates in one end and the ball grinding cylinder tube, and vacuum valve is equipped with in the another port.
Operation principle of the present utility model is: utilize heater that ball grinding cylinder is heated, at high temperature, motlten metal is carried out ball milling, produce the intermetallic compound powder of abrading-ball and motlten metal two constituent elements, in the utility model, ball milling is to carry out in a kind of solid metal and a kind of liquid metals, generates compound powder between solid metallic, abrading-ball (or ball grinding cylinder inner lining material) is participated in reaction directly, is one of intermetallic compound constituent element of being produced.Its beneficial effect is: existing limitation when (1) has overcome general milling mechanism and is equipped with intermetallic compound can prepare compound between the high-temperature metal that other method is difficult to prepare; (2) because the utility model is provided with temperature element and temperature controller, the ball grinding cylinder temperature is adjustable, ball milling medium of the same race, under different temperature, it is identical and form compound powder between different series metal to produce constituent element, and this also helps the formation mechanism of intermetallic compound and the still indefinite intermetallic compound of formation temperature are carried out pilot study; Research to basic theory aspects such as intermetallic compound, phasors also will produce important effect; (3) the utility model is simple in structure, easy to operate, with low cost.

The specific embodiment
As shown in Figure 1, the utility model comprises ball grinding cylinder 4, reductor 7 and adjusts motor 8 that ball grinding cylinder 4 places in the resistance furnace 3, and temperature controller 2 and thermocouple 1 are housed on the resistance furnace 3; Resistance furnace 3 is heated raw material in the ball grinding cylinder 4 by temperature controller 2 strict control temperature and is incubated; ball grinding cylinder 4 is driven around axial rotation by buncher 8 through reductor 7; rotating speed is regulated by buncher 8; the turning cylinder of ball grinding cylinder 4 is provided with intercommunicating pore 5; communicate in 4 of one end and the ball grinding cylinders; vacuum valve 6 is equipped with in the another port, in order to vacuumizing or feed protective gas in the ball grinding cylinder 4, eliminates the oxidative phenomena that may occur in the high-temperature reaction process.
Utilize device of the present utility model, abrading-ball is that iron ball, motlten metal are tin, under different temperatures, carry out ball milling, obtain following FeSn intermetallic compound: (ratio of grinding media to material: 30: 1, ball grinding cylinder rotating speed: 70～80 rev/mins) temperature (℃) time (hour) product illustrates 320 48 FeSn
2Mechanical alloying adopts the general milling machine to need FeSn mechanical alloying in 150 hours 600 120 to adopt the general milling machine can not generate 760 120 Fe
3Sn
2Mechanical alloying adopts the general milling machine can not generate 800 120 Fe
1.3The Sn mechanical alloying adopts the general milling machine not generate
