Due to the adoption of the technical scheme of putting lead at the bottom of the pot, qualified lead liquid does not need to be pumped into a casting mould by a lead pump. The lead placing pipe is positioned at the bottom of the lead melting pot, forms a small included angle with the bottom of the pot upwards and is positioned in the hearth, so that the temperature of the lead placing pipe is always kept above the melting point of lead, and lead liquid in the pipe cannot be blocked due to solidification during lead placing; before lead is put, a wrench is used for opening a lead putting valve to adjust the proper flow and flow rate, and the qualified lead liquid is put into a casting mold, so that the phenomena that the lead liquid is easy to oxidize, the slag rate is improved and alloy elements which are easy to oxidize in the alloy are seriously burnt and damaged due to the fact that lead pump lead generates lead flow and the lead is washed can be avoided.
The advantages are that:
1. low investment and convenient use.
2. The flow velocity of the lead liquid is stable, and the flow is controllable.
3. Lead is put at the bottom of the pot, so that oxide floating slag on the surface of the lead liquid can be prevented from entering a casting die, the burning loss of alloy elements is less, the elements are uniformly distributed and are not segregated, and the product quality is ensured.
4. The pot cover is connected with the pot spigot in a sealing mode, the production process is completed in a closed state, and generated waste gas can be discharged through the smoke outlet on the lead pot cover to enter a dust removal facility for purification, so that the waste gas is prevented from dispersing into a workshop, the pollution is reduced, and the working environment is improved.
