The flame retardant coating (4) that the inclusion of described casting ladle (1) inner wall surface applies is to take graphite as raw material, with clay, as bonding agent, makes, and the thickness of flame retardant coating (4) is 50～80mm, 1300 ℃～1600 ℃ of refractory temperatures.
The described bag support (2) that waters is to adopt stainless steel to make, and is of a size of: 750mm * 1000mm～1250mm * 1500mm, connected mode is welding or bolt connection.
The degree of depth of the arc stone arch bridge structure of described bag mouth (5) is 50～200mm, and length is 100～500mm, and root width is 100～500mm, and end width is 50～200mm, and the angle of arc stone arch bridge and horizontal direction is 15～40 °.
Described prolongation handwheel (3) is loaded on the input of reducer of turbodrill (8), extends the long 1～3m of handwheel (3), handwheel diameter phi 250～500mm, and the speed ratio of reducer of turbodrill is 1:4～15.
During work, first with fork truck, pitch casting ladle and be placed on plasma heating furnace drain hole, noble metal molten alloy flows into after casting ladle, start fork truck and move to casting area, bag mouth is facing to casting platform, and manual rotation extends handwheel, molten alloy in casting ladle flows on casting platform, form sheet metal alloy, then rotation extends handwheel, and the inclusion of casting ladle is vertically placed.
The beneficial effects of the utility model:
1, the graphite refractory that inclusion inner wall surface of the present utility model applies, it has high temperature resistant, thermal coefficient of expansion is little, not can with the advantage such as noble metal melt effect;
2, bag mouth of the present utility model adopts arc stone arch bridge structure, the wide end of root is little, when toppling over noble metal molten alloy, can control preferably the flow velocity of noble metal molten alloy like this, has avoided splashing of precious metal alloys liquid in casting cycle;
3, the utility model does not adopt electronic control, but adopt the prolongation handwheel that can dismantle at any time to control the casting of noble metal molten alloy in inclusion, so just avoided the calcination of electronic control line under hot environment dangerous, also avoid the rapid cooled and solidified of noble metal molten alloy in inclusion after unexpected power failure simultaneously, be unfavorable for the refining of later stage noble metal.
4, the utility model is convenient to operation, and long service life, safe, working environment is more friendly.
