Described steel construction shell suitable for reading is that up big and down small reducing is suitable for reading.
Described up big and down small reducing is suitable for reading to be that arc reducing curved surface is suitable for reading or truncated cone-shaped is suitable for reading.
Described up big and down small reducing is suitable for reading, and to connect a drum-shaped section on the suitable for reading or truncated cone-shaped section of a drum-shaped section suitable for reading in order to connect on the arc reducing curved sections.
The graphite annulus brick of described mozzle bottom is the following convex ring brick of being made up of four blocks of identical graphite bricks, this down in the outside and the steel construction shell lower end of convex ring brick along being superimposed and this descends the bottom surface of convex ring brick to exceed the bottom surface on edge in the steel construction shell lower end.
The described steel construction shell outside suitable for reading is provided with mozzle and lifts mechanism.
It is annular backing ring or three-pawl type mechanism that described mozzle is lifted mechanism.
A kind of assemble method that assembles described vacuum pouring honeycomb duct is characterized in that:
1) on metal tray, the graphite annulus brick of mozzle refractory brick and mozzle bottom is assembled into working lining,
2) metal backup shoe on the working lining upper flap that is assembled into,
3) pass metal screw at metal backup shoe and metal tray center, be assembled into the integral hoisting part after with nut the metal screw two ends being tightened,
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 invention 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) owing to adopted integrally-built steel construction shell, thoroughly taken leave of welding, cutting technique, have good looking appearance, bright and clean advantage.
