Embodiment 1
[0016] Embodiment 1. A method for separating plastic material and brittle material from rare earth silicon magnesium cored wire.
[0017] The mixed material described in this embodiment is a multi-core powder laminated composite cored wire: a rare earth silicon magnesium cored wire with a wire diameter of 13 mm, which is formed by laminating four kinds of powder materials, including ferrosilicon layer, pure It is very difficult to separate the magnesium particles in the magnesium particle layer, silicon calcium layer and rare earth silicon layer by ordinary sieving methods. Or use other methods to change the magnesium particles into relatively large flakes. At the same time, other powders will be rolled into smaller particles. After sieving, the larger flakes of magnesium flakes can be sieved out. The specific method is as follows:
[0018] 1) Using the roller rolling equipment, the gap between the rollers is adjusted to 0.5mm, and the above-mentioned multi-core powder lamina...
Embodiment 2
[0020] Embodiment 2. A method for separating plastic material and brittle material from silicon-calcium composite cored wire.
[0021] The composite cored wire described in this embodiment is a silicon-calcium cored wire with a wire diameter of 13 mm. It is formed by laminating ferrosilicon and calcium particles. The specific separation method is as follows:
[0022] 1) Using the roller rolling equipment, the gap between the rollers is adjusted to 0.5mm, and the above silicon-calcium composite cored wire is rolled; after rolling, the calcium particles are made into a relatively large sheet structure, and the cored wire Medium ferrosilicon is pressed into granules;
[0023] 2) Then, pass the rolled silicon-calcium composite cored wire through an 80-mesh fine sieve for sieving, and repeat the rolling once after sieving to remove brittle materials and obtain metal calcium material.
Embodiment 3
[0024] Embodiment 3. A method for separating plastic material and brittle material from titanium-aluminum composite cored wire.
[0025] The composite cored wire described in this embodiment is a titanium-aluminum composite cored wire, which is formed by stacking ferro-titanium and aluminum grains, and has a wire diameter of 13 mm.
[0026] The specific separation method is as follows: 1) Using the roller rolling equipment, the gap between the rollers is adjusted to 0.5mm, and the above-mentioned titanium-aluminum composite cored wire is rolled; after rolling, the aluminum particles are made into relatively large sheets Structure, ferro-titanium in the cored wire is pressed into granular form;
[0027] 2) Then, pass the rolled titanium-aluminum composite cored wire through an 80-mesh fine sieve to sieve. After sieving, the rolling can be repeated once to remove brittle materials and obtain metallic aluminum materials.
