4) with crane the integral hoisting part is sling and the steel construction shell of packing in, unclamp nut, metal screw and metal tray are taken off,
5) fill loose refractory in the gap between steel construction shell and mozzle refractory brick, form packed layer, suitable for reading with fire clay sealing packed layer, form overall vacuum cast mozzle.
The advantage of vacuum pouring honeycomb duct of the present utility model is:
1) owing to adopted and be the mozzle refractory brick of assembling integral hoisting and the graphite annulus brick spare and the integrally-built steel construction shell of mozzle bottom, assembling, convenient disassembly, quick, steel construction shell long service life are installed smoothly.
2) since in the outside of the graphite annulus brick of mozzle bottom and the steel construction shell lower end edge be superimposed, the diversed pipe refractory brick of graphite annulus brick is pressed in the steel construction shell lower end firmly along last, therefore can not turn up, thereby obturage packed layer, loose refractory in the packed layer can not bleed in the ingot mould, can not cause steel ingot to be mingled with; And the bottom surface of this following convex ring brick exceeds the bottom surface on edge in the steel construction shell lower end, can prevent that the lower edge steel plate from damaging because of hanging steel.
3), welding, cutting technique have thoroughly been taken leave of, attractive in appearance, the bright and clean advantage that had profile owing to adopted integrally-built steel construction shell.
