Preferably, described terne metal also adds and accounts for the aluminium that terne metal percentage by weight is 0.02-0.04% in the process that adds lead pan.Add after metallic aluminium, made the terne metal bath surface anti oxidation layer that formed one deck, thereby reduced the oxidation that common lead ashbury metal contact with air, the generation of the lead skim of minimizing terne metal melt generation.
Preferably, in step (4), lead pan, in the time that cast welding technique time out is 0.5-3h, is implemented Insulation in lead pan, and holding temperature control is 400 DEG C.
Preferably, in step (2), terne metal adds the time of lead pan to control as 1-4min.
Preferably, in step (4), when the terne metal in lead pan is lower than 50% time, in lead pan, add terne metal according to step (2).
Preferably, in step (4), the lead skim in lead pan is once salvaged removal by every 4h.
Preferably, described terne metal also adds and accounts for the germanium that terne metal percentage by weight is 0.02-0.04% in the process that adds lead pan.
Preferably, described terne metal also adds and accounts for the magnesium that terne metal percentage by weight is 0.01-0.03% in the process that adds lead pan.
Compared with prior art, beneficial effect is in the present invention:
1 has reduced slag yield, has been reduced to 10% by original 30%;
2 have avoided terne metal after fusing, to cause the reduction of the content of tin in the terne metal after cast welding due to lead and separating of tin;
3 have improved the utilization rate of terne metal.
