Electromagnetic induction electric melting furnace for controlling average nominal diameter of TiB2(TiC) particle group in Al-Ti-B (Al-Ti-C) alloy

Abstract

The invention relates to an electromagnetic induction electric melting furnace for controlling an average nominal diameter of a TiB2(TiC) particle group in an Al-Ti-B (Al-Ti-C) alloy, which comprises a furnace body used for accommodating alloy melt and coils arranged on the outer surface of the furnace body. Alternating current passes through the coils; the alloy in the furnace body induces a magnetic field generated by the current and is heated; the coils comprises a plurality of layers; and the frequency of drive current passing through each layer of coil in the plurality of layers is different from one another. The electromagnetic induction electric melting furnace for controlling the average nominal diameter of the TiB2(TiC) particle group in the Al-Ti-B (Al-Ti-C) alloy has the advantage that: a plurality of alternating magnetic fields are superposed in the furnace body, so that each part in the furnace body is under the action of magnetic force, the obtained average nominal diameter of the TiB2(TiC) particle group in the Al-Ti-B (Al-Ti-C) alloy is smaller, and the capability of refining solidified crystal grains of aluminum or aluminum alloys by the Al-Ti-B (Al-Ti-C) alloy is further improved.

Description

technical field [0001] The present invention relates to smelting equipment in the metallurgical industry, more specifically, relates to a method for controlling TiB in aluminum-titanium-boron (carbon) alloy 2 Electromagnetic induction melting electric furnace with average nominal diameter of (TiC) particle clusters. Background technique [0002] Aluminum-titanium-boron (or aluminum-titanium-carbon, the same below) alloy is a class of master alloys that are widely used in aluminum processing worldwide and are the most effective for refining the solidified grains of aluminum and aluminum alloys. Adding the above-mentioned aluminum-titanium-boron (carbon) alloy to aluminum or aluminum alloy can refine the solidified grains of the aluminum or aluminum alloy, thereby greatly improving properties such as yield strength, calendering plasticity, and ductile-brittle transition temperature. The manufacturing method of the aluminum-titanium-boron (carbon) master alloy that is generall...
