Series resonance multi-split online billet steel heating system

Abstract

The invention discloses a series resonance multi-split online billet steel heating system, and relates to the technical field of special metallurgy equipment. The series resonance multi-split online billet steel heating system comprises a rectification transformer and a rectification power supply cabinet; the rectification transformer is connected with the rectification power supply cabinet through transformer connection copper bars; the rectification power supply cabinet is connected with direct current connection copper bars; the direct current connection copper bars are in parallel connection with inversion power supply cabinets; each inversion power supply cabinet is connected with an induction heating coil through a water cooled cable; resonant heating is adopted, one rectifier is provided with a plurality of inverters, each inverter drags one induction coil, and each inverter adjusts power for heating alone. The series resonance multi-split online billet steel heating system adopts resonant heating, needs about 50 degrees of electricity to heat a ton of billet steel, not only reduces the cost, but also saves energy.

Description

technical field [0001] The invention relates to the technical field of special metallurgical equipment, in particular to a series resonance one-drag multi-online billet heating system. Background technique [0002] There are two traditional on-line steel billet heating methods, one is the gas produced by the gas generator, on the one hand, burning coal produces a large amount of toxic gas to pollute the air; around yuan. Another way is to use parallel resonance induction heating. It takes about 60 degrees of electricity to heat a ton of steel billet. Although the cost is reduced, the parallel resonance induction heating cannot realize one drag and more because its power adjustment is to adjust the rectification angle. When the system fails, the entire production line must be shut down for maintenance, causing unnecessary losses, and the rectification angle cannot be fully opened, resulting in low system power factor and wasting energy.

Another way is to use parallel resonance induction heating. It takes about 60 degrees of electricity to heat a ton of steel billet. Although the cost is reduced, the parallel resonance induction heating cannot realize one-to-many because its power adjustment is to adjust the rectification angle. When the system fails, the entire production line must be shut down for maintenance, causing unnecessary losses, and the rectification angle cannot be fully opened, resulting in low system power factor and wasting energy
