The Crude lead refining furnace is mainly composed of refining furnace, refining pot, dust collecting hood, operating platform, linear casting machine, lead fume purifier and control system(Final configuration may vary based on client requirements and the desired end product).
Crude Lead Refining Plant Process Flow
Lead Refining Process Description:
1. Charging
Charge the refining furnace or kettle to ~80% capacity with recycled crude lead (e.g., from smelting) or lead battery grids.
2. Heating & Melting
Heat and stir the lead charge until fully molten.
3. Impurity Removal
Add various refining agents and stir. Skim off dross (impurities) after reactions complete.
4. Quality Control
Test the molten refined lead to determine its elemental composition.
5. Alloying
Sequentially add precise amounts of alloying elements (e.g., Calcium, Tin) to produce lead alloys as required.
6. Casting Preparation
Sequentially activate the Linear Casting Machine’s: Chain Conveyor, Circulating Cooling Water System, Ingot Marking/Stamping Machine, Lead Ingot Conveyor.
7. Casting
Tap the molten refined lead alloy into the casting machine to form ingots.
Following processing in the lead refining plant, the resulting refined lead alloy ingots achieve a purity level of 99% to 99.9999%.
Raw Material & Output
Crude Lead ingot purty: 95%-98%, Lead ingot purity : 99%-99.9999%.
