Amorphous alloy double-belt type continuous casting machine and continuous casting method thereof

Abstract

The invention discloses an amorphous alloy double-belt type continuous casting machine and a continuous casting method thereof. The double-belt type continuous casting machine comprises a rack, an upper belt part and a lower belt part; the upper belt part and the lower belt part are both fixed to the rack; the upper belt part comprises a heating roller, a first supporting device, a second supporting device, a first tensioning device, a driven device and an upper steel belt; the lower belt part comprises a first distance adjusting device, a second distance adjusting device, a third distance adjusting device, a second tensioning device, a driving device and a lower steel belt; the portion, between the first tensioning device and the heating roller, of the upper belt steel and the portion, between the first distance adjusting device and the second distance adjusting device, of the lower belt steel form a molten pool used for containing amorphous alloy liquid; an inclined plane is formed between the upper steel belt and the heating roller, and two tangent lines tangential with a rotating roller of the driven device; another inclined bevel is formed between the lower steel belt and three tangent lines tangential with a rotating roller of the first distance adjusting device, the second distance adjusting device and the third distance adjusting device; and the two inclined planes areparallel to each other, and a coagulation area is formed between the two planes.

Description

technical field [0001] The invention belongs to the technical field of metal material casting, and in particular relates to a double-belt continuous casting machine for casting amorphous alloys and a continuous casting method for amorphous alloys. Background technique [0002] Compared with ordinary crystalline alloys, amorphous alloys have superior mechanical properties and physical and chemical properties. As a new type of material, amorphous alloy not only has extremely high strength, toughness, wear resistance and corrosion resistance, but also exhibits excellent soft magnetism and superconductivity, and has been widely used in the fields of electronics, machinery and chemical industry. application. However, the current preparation technology of amorphous alloys is copper mold suction casting method, powder metallurgy technology, melt water quenching method, die-casting method, etc. The above methods are limited to the production of amorphous alloys with fixed specifica...

Problems solved by technology

However, when the mold is used to inject the alloy liquid into the continuous casting machine, the alloy liquid will fluctuate at the outlet of the mold. This fluctuation has not been formed smoothly, resulting in ripple defects on the surface of the billet.

It can be seen that using the crystallizer to inject the alloy liquid into the casting machine is obviously insufficient, which affects the surface quality of the slab
