The utility model provides a kind of oxygen-free copper bar continuous casting unit novel eddy-current heating electric furnace, comprise body of heater, inductor and channel, body of heater shell adopts quartz sand to burn and builds up type, and body of heater furnace lining adopts refractory brick to pile up and forms, fill insulant material between body of heater shell and body of heater furnace lining; Described inductor comprises iron core and induction coil, and described iron core adopts high-density silicon steel disc to make, and described induction coil adopts square copper tube make and fill cooling water in square copper tube; Channel is annular ditch, is full of melt in channel, and induced-current flows in the melt.The utility model adopts fusing, heat-insulating integral structure, does not need protective gas just can have good oxygen barrier protection and heat insulation effect, bath composition is stablized, oxygen-free copper bar good product quality.
Description
Technical field
The utility model relates to the novel eddy-current heating electric furnace of a kind of oxygen-free copper bar continuous casting unit, belongs to copper industry processing technique field.
Background technology
Traditional Copper fabrication can be divided into: melting and casting, hot-working and cold working syllogic, traditional Copper and its alloy mode of production has been broken in the birth of UPCAST technology and development, further shorten process for copper technological process, and improve the quality of copper products to a certain extent.But; there is technical defect in existing oxygen-free copper bar continuous casting unit eddy-current heating electric furnace; namely body of heater oxygen barrier protection and heat insulation effect poor; the copper liquid temperature at crystallizer place is made to be subject to frequently adding the impact of cold feed; fluctuate very large; be difficult to control, due to copper liquid quality extremely unstable, therefore directly affects the quality of copper bar product.
Utility model content
For above deficiency, the utility model provides a kind of oxygen-free copper bar continuous casting unit novel eddy-current heating electric furnace, improves oxygen barrier protective agent heat insulation effect, ensure that the quality of oxygen-free copper bar.
The technical solution of the utility model: the novel eddy-current heating electric furnace of oxygen-free copper bar continuous casting unit, comprise body of heater, inductor and channel, body of heater shell adopts quartz sand to burn and builds up type, and body of heater furnace lining adopts refractory brick to pile up and forms, fill insulant material between body of heater shell and body of heater furnace lining; Described inductor comprises iron core and induction coil, and described iron core adopts high-density silicon steel disc to make, and described induction coil adopts square copper tube make and fill cooling water in square copper tube; Channel is annular ditch, is full of melt in channel, and induced-current flows in the melt, between channel and furnace bottom, be folded with rock layers.
The utility model has following technique effect: the utility model adopts fusing, heat-insulating integral structure, does not need protective gas just can have good oxygen barrier protection and heat insulation effect, bath composition is stablized, oxygen-free copper bar good product quality.
