Problems solved by technology

This method tries to use pressure to help inject the melt, but it does not solve the problem that the alloy liquid at the injection hole is poorly matched with the heating coil, and the injection hole may still be blocked.
[0010] In addition, small quick quenching furnaces also have the following disadvantages: (1) It often takes a long time for the furnace chamber to reach high vacuum from normal pressure, and when the volume in the chamber is large, the time requi

Example Embodiment

[0045] Example 1:

[0046] In this embodiment, such as figure 1 versus 2 As shown, the continuous vacuum rapid quenching equipment includes a main cavity 1 which is used to fix the mechanical parts loaded in the main cavity 1 and is isolated from the external environment such as air and water. The main cavity 1 is provided with a main cavity door 20, and the main cavity door 20 is opened when parts are assembled or repaired. In the working state, the main cavity 1 is sealed. A heating body 6, an induction coil 3, and a cooling device for rapid quenching are provided in the main cavity 1.

[0047] The heating body 6 is a crucible, and the whole crucible is in the shape of a round cup with an inner diameter of 40-60 mm. The crucible is made of aluminum oxide, magnesium oxide, silicon carbide or quartz. The bottom of the crucible 6 has a leak hole with a diameter of about 1 mm.

[0048] The appearance of the induction coil 3 is a spiral formed by a hollow water-cooled copper tube. Th...

Abstract

The invention provides continuous vacuum rapid quenching equipment. Based on traditional rapid quenching equipment, the equipment is additionally provided with a transition cavity, a clamping device, a collecting device and a vacuuming device; the equipment improves such problems as need of opening/closing a main cavity door in each operation, manual loading of a heating body and manual collection of quenching products in the traditional equipment; and the equipment can realize continuous operation to reduce the energy and time consumption and to improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a continuous vacuum rapid quenching device and a method for metal rapid quenching using the device. Background technique [0002] For ease of use, bulk metals smelted from ores are usually first crushed into shapes such as granules, strips or flakes, and then shaped by powder metallurgy processes such as sintering or bonding, and finally processed into parts of mechanical and electronic equipment. [0003] The method of crushing bulk metal into particles was simple mechanical crushing in the early days, but the residual stress brought by this method was very large. Later, ball milling with steel balls and liquid medium, jet mill using high-pressure airflow to make materials collide with each other, and hydrogen absorption crushing for some rare earth alloys were developed. Among them, the melt quenching technology is used to spray the molten alloy liquid onto the water-cooled...
