Problems solved by technology

For the case of a single furnace where the quality of the alloy raw material remains unchanged, the height of the alloy liquid level can be regarded as gradually decreasing; but for the case of midway feeding or continuous feeding, the change of the alloy liquid level is more complicated, and the tilting angle of the crucible needs to be adjusted in real time, so , to maintain a stable pouring speed of the alloy liquid throughout the pouring stage, the control is more complicated

Embodiment 1

[0048] In this embodiment, the overall structure and main components of the alloy rapid solidification equipment are as follows: figure 1 As shown, it mainly includes a furnace body 1, an induction coil 6, a crucible 5, a tundish 7, a nozzle 9, a cooling roller device and a control center.

[0049] The furnace body 1 is used to fix and load the mechanical parts inside it, and isolate these parts from the external environment such as air and water. The furnace shell is made of ordinary carbon steel or stainless steel. A feed inlet 2 is arranged above the furnace body 1, and a discharge outlet 3 is arranged below. The feed port 2 is used to load prepared raw materials or alloy ingots. The outlet 3 is used to output alloy powder after rapid solidification treatment. The material inlet 2 and the material outlet 3 can be further connected to the material transition cabin, so that the equipment can be turned into continuous operation from single furnace start-up and shutdown.

Embodiment 2

[0068] In this embodiment, the alloy rapid solidification equipment is basically the same as that of Embodiment 1, the difference is that the structural diagram of the rotating device in this embodiment is as follows Figure 5 As shown, it is mainly composed of a driving worm 34, a driven worm gear 33, a coil connecting rod 29 and a rotating motor; one end of the coil connecting rod 29 is connected with the induction coil 6, and the other end is connected with the driven worm gear 33 through a magnetic fluid dynamic seal 28; The tooth groove shape of the worm 34 is matched with the driven worm gear 33. Driven by the rotating motor, the driving worm 34 performs a linear or rotational motion, which drives the driven worm gear 33 to rotate, and the coil connecting rod 29 rotates accordingly, thereby driving the induction coil 6 to rotate horizontally. When the shaft rotates, the crucible 5 falls, and the alloy liquid therein is poured out.

Embodiment 3

[0070] In this embodiment, the alloy rapid solidification equipment is basically the same as that of Embodiment 1, the difference is that the structural diagram of the rotating device in this embodiment is as follows Figure 6 As shown, it is mainly composed of a spinner 35 and a coil connecting rod 29; one end of the coil connecting rod 29 is connected with the induction coil 6, and the other end is connected with the spinner 35 through a magnetic fluid dynamic seal 28; the spinner 35 is connected with the hydraulic pressure The rods 36 are connected, and the hydraulic station composed of a reversing valve, a proportional hydraulic valve, and an oil pressure pump provides driving force to the hydraulic rod 36, and the hydraulic rod 36 is pulled to drive the spinner 35 to rotate axially, and the coil connecting rod 29 follows The rotation, thereby driving the induction coil 6 to rotate around the horizontal axis, the crucible 5 is dumped, and the alloy liquid therein is poured ...

Abstract

The invention provides an alloy rapid solidification device. The equipment includes a furnace body, an induction coil, a crucible, a tundish connected to the nozzle at the bottom, a cooling roll device, and a control center; the crucible is located inside the induction coil and is fixedly connected to the induction coil, and the induction coil can rotate around the horizontal axis under the action of the rotating device. Rotation; the tundish is installed in the air through the support device, and the support device is equipped with a weight sensor; in the working state, under the action of gravity, the tundish and the alloy liquid in the tundish generate pressure on the support device, and the weight sensor detects the pressure signal and transmits it To the control center, the control center compares it with the set reference value to control the rotating device, thereby adjusting the pouring angle of the crucible, so that the amount of alloy liquid poured per unit time remains stable, so the entire rapid solidification process is in a relatively balanced state , thereby improving the consistency and quality of product performance during the manufacturing process.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment for rapid solidification of molten metal alloys, in particular to an alloy rapid solidification equipment and a method for using the equipment to rapidly solidify alloys. Background technique [0002] The manufacturing process of metal alloys usually includes processes such as component ratio, smelting, solidification, and heat treatment. Specifically, it includes melting two or more elements such as metals (such as iron, copper, nickel, etc.) and non-metals (such as carbon, boron) into a liquid state at high temperature according to a certain composition ratio, and then undergoing natural Or forced cooling process, solidified into blocks or other shaped products. Among them, solidification refers to the transition of a metal alloy from a liquid state to a solid state, which is a phase change process. In most cases, solidification of metals is a process of formation and growth of...
