Instructions For Horizontal Splicing
NOTE: A crucible should not be reused until allowed to
cool for 15 minutes or more. If more frequent use
is desired, several crucibles complete with frames
should be used alternately to allow sufficient cooling
time.
Clean crucible thoroughly inside. Empty the crucible
completely. See Note 13 & 14 on this page for
additional information. Do not use a wire brush.
Place crucible ceramic insert in bottom of crucible.
All crucibles use the same ceramic insert.
The crucible ceramic insert assembly is supplied with a
steel disk pre-installed into it as a one-piece assembly.
If the steel disk is not present in the ceramic insert, place
the steel disk on the crucible ceramic insert and check for
proper seating.
Remix bag of CADWELD ® filler material and fill crucible
according to the instructions on page 7.
10. Position crucible on the pouring basin and secure the
tiedown chain. Keeping it just loose enough to allow
swivelling of the crucible without tipping.
11. Open the starting material container. Evenly distribute
the starting material over the filler material in the crucible,
saving a small amount to be placed on the tab of the
crucible extension. Place the crucible extension on the
crucible and put the remainder of starting material
on the tab. Place the crucible cover on the extension.
Standing off to the side of the opening and up wind,
ignite the starting materials on the tab.
12. Keep the tiedown chain secured at all times.
Immediately after the sleeve has filled, slowly swivel
the crucible back and forth to break the slag between
the base of the crucible and top of the pouring basin.
Repeat after 15 to 20 seconds as necessary. After the
slag has solidified, release the tiedown chain and remove
the crucible. All other parts can then be removed.
13. Clean the crucible by turning upside down and placing
a metal rod (#5 [16mm] rebar) against the ceramic and
lightly tapping the rod end to discharge the slag and
ceramic into a suitable waste container.
14. Break off riser with hammer. Clean slag from crucible
and pouring basin as soon as possible to promote cooling.
Use a whisk broom, rag or wooden wedge for cleaning.
Do not use a wire brush. Cover and crucible extension
need not be cleaned every time.
NOTE: Clean flash or debris from all mating surfaces as this
causes springing of the equipment clamps and hinges.
