Abstract

The invention discloses a process and system for smelting and casting iron-silicon-aluminum alloys, belonging to the field of manufacturing metal soft magnetic materials. A smelting and casting process of ferrosilicon aluminum alloy, which includes the following steps: A, batching: weighing the raw materials according to the weight ratio; B, smelting: adding the materials into a non-vacuum induction furnace (1) to melt into molten steel; C, Casting: Pour molten steel into a container (2) filled with high-purity water to obtain finely divided alloys; D. Drying: Dry and dehydrate the alloys. A system for smelting and casting a sendust aluminum alloy, which includes a non-vacuum induction furnace (1), a container (2) and a drying oven (7). The invention has the beneficial effects of reducing the manual hammering and jaw crushing procedures in the ingot casting method, thereby reducing the labor cost and processing time; the operation is simple, the production cycle is short, and the output of a single furnace is large; no mold is needed, thereby saving costs ; The product yield is high; water quenching increases the brittleness of the alloy and improves the crushing efficiency.

Description

technical field [0001] The invention belongs to the field of manufacturing metal soft magnetic materials, and in particular relates to a melting and casting process and system of a silicon-silicon-aluminum alloy. Background technique [0002] Soft magnetic materials are widely used in various circuit designs because of their special functions of magnetoelectric conversion and energy storage filtering. Miniaturization" development direction, the composition of 9.1-9.8% Si, 5.0-6.0% Al, Fe-SiAl soft magnetic material has high saturation magnetic induction, high magnetic permeability, good DC superposition characteristics, high frequency Low loss (lower device temperature rise), good temperature stability, excellent comprehensive magnetic properties and good cost performance are the ideal soft magnetic materials to achieve the above requirements. [0003] However, sendust has the physical characteristics of high hardness and brittleness, so it cannot be rolled into strips, nor...
