2) utilize the device of the utility model and adopt the method for the utility model, the molten metal in the cast is flowed steadily and control easily;
3) utilize this device to implement the quantitatively method of cast, the precision that molten metal is quantitatively poured into a mould is high, and the job run cost is low.
Description of drawings
Fig. 1 is the quantitative pouring apparatus structural representation of the utility model metal bath.
Fig. 2 is that the quantitative casting method of the utility model metal bath is implemented view.
The specific embodiment
Referring to Fig. 1, the quantitative pouring apparatus of the utility model metal bath is constituted by critical pieces such as smelting furnace 1, smelting furnace elevating mechanism 2, holding furnace 3, catheter 4, protection device of air 8, forcing pipes 9.
The chief creating point of the utility model is: at first set up a holding furnace that has liquid outlet 53 that coordination is high at the side of smelting furnace 1, the equivalent diameter of design smelting furnace liquid storage pool will be much larger than the equivalent diameter of (at least greater than 2 times) holding furnace liquid storage pool; Again through setting smelting furnace elevating mechanism 2 so that smelting furnace can move vertically; Let smelting furnace 1 and holding furnace 3 be interconnected through catheter 4; All be provided with airtight bell 7,10 smelting furnace 1 and the suitable for reading of holding furnace 3, and airtight bell 7,10 can heat respectively and temperature control; At least cover at smelting furnace and be provided with a forcing pipe 9, the crucible melt of melting bell 10 in both can airtight smelting furnace can use gas as pressurizeing in the smelting furnace through forcing pipe 9 again; Also be provided with one can in smelting furnace and holding furnace, feed the molten metal protective gas protection device of air 8, protective gas feeds protection gas through this protection device of air 8 in smelting furnace 1 and holding furnace 3, to prevent metal alloy oxygenization.
Described smelting furnace elevating mechanism 2 can adopt active forces such as machinery, hydraulic pressure or motor to drive, and smelting furnace integral body can be moved vertically, to cooperate the completion of pouring practice.
Be respectively equipped with filter 6,12 and 13 in holding furnace liquid outlet 5 and catheter two-port.
The catheter body can be processed by steel lining or fire-resistant, insulation material.Being exposed to outside traversing section catheter skin, also can be provided with calandria.
The course of work of the utility model metal bath quantitative pouring apparatus is: at first, and earlier through forcing pipe 9 initial liquid level H in capacity fusing and airtight smelting furnace 1
0Apply initial gas pressure P
0This initial gas pressure P
0>=(H-H
0) * ρ
Density metal, wherein, H is the height of catheter upper end, makes metal liquid inject catheter and holding furnace, and reaches the operating fluid level height H of initial cast
1, simultaneously the metal liquid that injects holding furnace is carried out double refining and the serial melt treatment of modifying-refining.Then, start smelting furnace elevating mechanism 2, make the position of smelting furnace 1 begin to rise, make liquid level and holding furnace 3 level balances also be H
