An induction heating system for a silicon steel core with a self-adhesive coating that includes an induction heating device having a columnar induction heating coil with a hollow cavity that carries out induction heating on a silicon steel plate at a medium frequency of 6-20 KHz. By rapid induction heating at a medium frequency, a silicon steel core with a self-adhesive coating can be rapidly cured, thereby greatly shortening the processing time, improving production efficiency, and facilitating automated operation in the production of a silicon steel core with a self-adhesive coating. The system also ensures the quality of the cured core products that can be widely applied in the field of the production of silicon steel cores with a self-adhesive coating.

An electromagnetic stirring device and a method for a secondary cooling zone during slab continuous casting. The device has a main body, an opening adjustment assembly, and a secondary cooling assembly. The main body has a protection housing (), a phase sequence control assembly, an iron core () and an electromagnetic coil () for carrying out variable-direction electromagnetic stirring on a molten steel by a three-phase current phase sequence transformation. The opening adjustment assembly has an air cylinder (), a fixed base (), a movable joint shaft () and a silicon steel sheet group insert () for adjusting online opening degree of the closed annular iron core by a movable joint structure. The secondary cooling assembly has a cooling water inlet () and a cooling water nozzle () for cooling the electromagnetic coil and spraying cooling water to a surface of a cast slab ().

Disclosed are a method and a device for controlling flow of liquid zinc () in a zinc pot () for hot-dip galvanization. Under the blowing effects of an air knife above the zinc pot () for hot-dip galvanization onto strip steel (), the liquid zinc () diffuses and flows outwards to zones (zones I, II, III and IV) comprising the left side, the right side, the front end of the zinc pot, respectively, and a zone between the strip steel () and a furnace snout (), and surface dross rapidly generated on the surface of the liquid zinc () is driven to flow outwards to the zones (zones I, II, III and IV). On edge sides of the zones (zones I, II, III and IV), travelling magnetic field generators () are arranged in multiple sections above the surface of the liquid zinc () in the zinc pot (), so as to excite a travelling magnetic field to generate an electromagnetic driving force on the liquid zinc () to drive the flow of the liquid zinc (). The flow of the liquid zinc () caused by the travelling magnetic field generators () is engaged with the blowing flow of the air knife, driving the surface liquid zinc () in the zinc pot () to flow in order towards a rear end (zone V) of the zinc pot (). The surface dross floating on the surface of the liquid zinc () is driven by the flowing liquid zinc () to flow in a controlled direction.
