Magnesium alloy material smelting device

Abstract

A magnesium alloy material smelting device comprises a smelting furnace and a disc type filling device, the disc type filling device comprises a stirring shaft, a filling basket and a disc type stirring head, the stirring shaft is connected with the filling basket, the bottom of the filling basket is connected with the disc type stirring head, the disc type stirring head comprises a plurality of stirring wings, and the stirring wings are connected with the filling basket and a stirring disc. The connecting ends of the stirring wings are mutually connected, the stirring ends extend to the edge part of the stirring disc, and a liquid through hole is formed in the side wall of the filler basket; in the process of preparing and processing the magnesium alloy, the disc type stirring head can accelerate diffusion, the disc type stirring head rotates to divide molten liquid into an upper layer and a lower layer, the molten liquid on the upper layer forms a solution vortex, and diffusion of intermediate alloy elements is accelerated; and the lower-layer melt is kept relatively static, so that the precipitated slag is prevented from turning upwards, the slag precipitation time is shortened, and the productivity is improved.

Description

Technical field [0001] The present invention relates to the field of alloy melting technology, specifically a magnesium alloy material melting device. Background [0002] Magnesium alloys are alloys based on magnesium and composed of other elements. It is characterized by: small density (1.8g / cm 3 Left and right), high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, good corrosion resistance to organic matter and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. The most widely used magnesium-aluminum alloys are followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. At present, the progress of science and technology has increased the requirements for new materials, as well as the reduction of magnesium alloy prices and the superior performance of magnesium alloys, which have made magnesium alloys used i...

Problems solved by technology

However, even so, in the process of preparing the alloy, it is necessary to manually clamp the pure metal and the intermediate alloy into the solution for washing, which leads to the continuous destruction of the covering layer formed on the surface of the magnesium liquid, resulting in the contact between magnesium and air, continuous combustion, and the formation of more magnesium alloys. There are many oxidized slag inclusions, and the stirring rod stirring process will also drive the slag inclusions at the bottom of the furnace to continuously turn upwards, resulting in low consistency in the performance and chemical composition of the production materials, uneven composition, and low yield; The analysis process is time-consuming and inefficient; workers are inefficient and labor-intensive
