Abstract

The invention discloses a device for achieving continuous casting of a vacuum induction furnace and a method thereof. A smelting furnace is divided into three cavities by the vacuum induction furnace,two charging chambers, two crucible systems and two furnace vehicles are arranged, staggered smelting of two crucibles and alternate casting are adopted to achieve single small-capacity production orcontinuous alternate casting method is adopted to achieve the production effect equal to large-capacity equipment, large-specification casting ingots are cast, the equipment production product specification coverage is wide, investment is lowered, and production flexibility of small and medium sized enterprises is improved.

Description

technical field [0001] The invention belongs to the field of special metallurgy and relates to a device and method for realizing continuous casting in a vacuum induction furnace. Background technique [0002] Vacuum induction melting is an important smelting equipment for the production of special steel, precision alloys, high-temperature alloys, and corrosion-resistant alloys. It is a complete set of equipment integrating various technologies such as machinery, electronics, and vacuum. [0003] At present, the operation mode of vacuum induction furnace is usually divided into two modes: periodic mode and semi-continuous mode. The periodic furnace has only one vacuum chamber, in which the entire smelting process of charging, melting and pouring is completed. After completing the smelting task of one furnace, take out the steel ingot, start loading again, arrange the ingot mold, vacuumize the furnace together, and start a new furnace smelting. The operating efficiency is lo...
