Coiling furnace device for magnesium alloy strip coil furnace coiling rolling and furnace coiling rolling unit

Abstract

The present invention is applicable to the field of magnesium alloy coil coil rolling equipment, and provides a coiling furnace device for magnesium alloy coil coil rolling, which includes a furnace shell provided with a furnace mouth; located in the furnace shell, A reel for coiling magnesium alloy coils; an eddy current heating unit installed in the furnace shell for heating magnesium alloy coils; a high-temperature heat-resistant insulation layer covering the inner surface of the furnace shell; covering the inner surface of a high-temperature-resistant heat-insulation layer protective lining. In the process of coiling the magnesium alloy coil, the magnesium alloy coil is heated by the eddy current heating unit. Since the eddy current effect is used for heating, the heating unit is not in contact with the magnesium alloy coil during the heating process, and because no gas is used, naturally no Flue gas containing corrosive substances and viscous substances will be generated, which improves the life of the coiling furnace device and the surface quality of the output magnesium alloy coil.

Description

technical field [0001] The invention belongs to the field of magnesium alloy strip coil rolling equipment, and in particular relates to a magnesium alloy coil coil rolling coiling furnace device and a coil rolling unit. Background technique [0002] Magnesium alloy has many excellent properties: specific strength is better than aluminum and steel; specific rigidity is close to aluminum and iron, far better than plastic; good impact resistance, equivalent to 1.5 times of aluminum; good shock resistance and noise reduction performance; good thermal conductivity ; Good electromagnetic shielding and radiation protection; degradable, recyclable and other superior properties, magnesium and magnesium alloys are by far the lightest metal structural materials in engineering applications. At present, magnesium alloy products are mainly casting parts, not plastic deformation parts. Since magnesium has a close-packed hexagonal crystal structure, the c / a axis ratio is 1.623, and there is...
