Said catheter is fixed on smelting furnace by the catheter cutting ferrule and covers.
In the quantitative pouring apparatus of metal bath, the equivalent diameter of the liquid storage pool of said smelting furnace is greater than the equivalent diameter of holding furnace liquid storage pool.The equivalent diameter of this smelting furnace liquid storage pool is at least greater than 2 times of holding furnace liquid storage pool equivalent diameter.
In the quantitative pouring apparatus of metal bath, be respectively equipped with filter at holding furnace liquid outlet and catheter two-port.
The utility model has the advantages that:
1) this apparatus structure is simple and reliable, and result of use is good, whole flow with casting process under protective atmosphere and process be airtight, unusual steady, non-oxidation.Can eliminate volume gas and oxidation in the pouring metal melt process greatly;
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.
Catheter 4 one ends of said connection smelting furnace 1 and holding furnace 3 are vertical to be inserted in the liquid level of smelting furnace 1, and insertion depth is for estimating to accomplish the degree of depth of the required consumption metal liquid of pouring practice; The other end of catheter 4 vertically inserts in the holding furnace 3, and insertion depth is for guaranteeing that the lower end of catheter still is lower than H in the holding furnace when smelting furnace rises to the required extreme higher position of pouring practice 1, this H 1Operating fluid level height for whole casting process.The port at these catheter 4 two ends all is added with filter 12 and 13, and being positioned at the catheter part that smelting furnace covers can be fixing by catheter cutting ferrule 11.
