Connect, the inner core cooling device includes bore graphite cannula and inner core water cooling tube, the bore graphite cannula is sleeved on the pipe
In external diameter graphite cannula centre bore, the inner core water cooling tube is arranged in bore graphite cannula centre bore, and the fastener includes stone
Inky cap plate, pressure strip and locking nut, the graphite cover plate are covered in the outer water collar and pipe external diameter graphite cannula side outer end
Top, the pressure strip is pressed in the top of graphite cover plate and bore graphite cannula side outer end and locked by locking nut,
In pipe external diameter graphite cannula lower end endoporus side, correspondence offers molten iron entrance.
Further, outer wall cooling duct is offered on the outer water collar excircle, and outer wall cooling at an upper portion thereof is logical
Road two ends correspondence offers outer wall coolant intake and outer wall cooling water outlet mouthful.
Further, the inner core water cooling tube two-port is respectively inwall coolant intake and inwall cooling water outlet mouthful.
The present invention has the advantage that compared with prior art：The hidden danger that inner core leakiness water produces blast is eliminated, by
In its contraction in length, ensure that inner core is more firm by fastener.Cost of manufacture is reduced, easy to operate.Produce tubing
Wall thickness uniformity is improved.
