Lead Metal Alloying Process
Gravita offer various Lead Alloys manufacturing processes & Kettle / Pots, which are of highest precession of desired Specification. Company’s strength lies in process to manufacture Lead-Calcium Alloy and Lead Selenium Alloy, which are used in grid casting for maintenance free & low maintenance Lead-Acid Battery manufacturing.
Company supply alloying pots of various capacities ranging from 5-50 MT per batch accompanied by high efficiency natural gas / LPG Gas / furnace oil burners equipped with preheating arrangements. Emissions are controlled by a flexible kettle hood, with series of Pollution Control Equipments chained with Wet Scrubber, attached to an Induced Draft Fan along with a chimney/stack arrangement.Company configures the total alloying plant package(s) as required.
Gravita supplies range of special fluxes designed to reduce dross formation and increase process efficiency. The refining unit complement is completed by the automatic Lead ingot-casting machine (with Lead-Pump) having a production capacity of up to 10-20 MT/hr. Refining unit package is optimally configured for high throughput with good emission control, as proven by the existing installations in operation. Gravita has the capability to manufacture different Lead alloys to stringent user-industry determined specifications:
