Embodiment 1

[0030] Such as figure 1 The shown high-efficiency double-layer forward and reverse stirring equipment for magnesium alloy smelting includes a crucible 24, a mixer fixed platform 17 installed on the crucible 24, a reducer bracket 5 fixedly installed on the mixer fixed platform 17, and a mixer fixed platform 17. Flux powder sprinkling port 25, the flux powder sprinkling port 25 on the mixer fixed platform 17 is convenient to spray refining agent in the crucible 24.

[0031] Stirrer fixed platform 17, speed reducer support 5 middle part wears stirring device, the stirrer fixed platform 17 on the crucible 24 is used for supporting stirring device, stirring device comprises short rod stirring hollow shaft 19 and the long rod that is sleeved in the short rod stirring hollow shaft 19 The rod stirs the solid shaft 6, and the upper end of the long rod stirs the solid shaft 6. The speed reducer 3 placed on the speed reducer bracket 5 is fixedly installed, and the output end of the frequ...

Embodiment 2

[0035] Such as figure 2 The difference between Embodiment 2 and Embodiment 1 of the high-efficiency double-layer positive and negative stirring equipment for magnesium alloy smelting shown is that a flux powder sprinkling port cover 26 is detachably installed on the flux powder sprinkling port 25 . When it is not necessary to spray refining agent into the crucible 24 through the flux powder sprinkling port 25 , the flux powder sprinkling port cover 26 can be covered on the flux powder sprinkling port 25 .

[0036] The fixed platform 17 of the mixer is in a convex shape, and the outer side of the upper part of the short-rod stirring hollow shaft is fixedly installed with a double-piece clamping rod 28, and several steel wire brushes 29 are evenly fixed and installed on the double-piece clamping rod 28, and the double-piece clamping rod 28 is arranged below There is a flux leaking chamber plate 30 which is offset against the steel wire brush 29 and provided with several flux le...

Abstract

The invention belongs to the technical field of magnesium alloy smelting and casting. The invention relates to a double-layer mechanical stirrer used in a magnesium alloy smelting process. A stirringdevice in the middle of a stirrer fixing platform on a crucible comprises a short-rod stirring hollow shaft and a long-rod stirring solid shaft sleeved in the short-rod stirring hollow shaft; short-rod stirring rotors are arranged at the free end of the lower part of the short-rod stirring hollow shaft in a staggered manner; long-rod stirring rotors are arranged at the free end of the lower part of the long-rod stirring solid shaft in a staggered manner; a lower rotor gear is fixedly mounted at the upper end of the short-rod stirring hollow shaft; an upper rotor gear is fixedly mounted at theupper end of the long-rod stirring solid shaft; a left rotor gear and a right rotor gear which are meshed with the upper rotor gear and the lower rotor gear are fixedly mounted on the two sides of theupper rotor gear and the lower rotor gear respectively; the problems that in the existing magnesium alloy smelting process, stirring is uneven and insufficient, the surface of magnesium liquid is prone to fire to generate oxidizing slag for the second time, and the segregation phenomenon is serious are solved.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloy smelting and casting, and relates to a double-layer mechanical stirrer used in the magnesium alloy smelting process. Background technique [0002] Magnesium alloy is an alloy composed of magnesium as a matrix and other elements. Its characteristics are: low density (1.8g / cm 3 Magnesium alloy or so), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good corrosion resistance to organic substances and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Magnesium-aluminum alloys are currently the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. It is the lighte...
