Typically, metal from the smelting
furnace is melted in an indirect-fired kettle or pot. By using appropriate
process methods, upto 99.97% refined lead is obtained.
Trace
elements are combined to produce the desired alloy. Our design takes care
of the possible fume emissions to safeguard the working environment.
Some lead emissions can occur from poorly controlled refining, casting, and
drossing operations. Exhaust ventilated enclosure is provided for
refining kettles.
Appropriate Stirrers are provided with the refining and alloying plants to
stir the molten metal to optimize the reactions during refining and alloying of the metal with high-grad
safety to the operators and ease in operation and maintenance.
Lead produced during smelting operations
is remelted in iron kettles and refined by the addition of reagents,
such as sulphur and caustic soda. The purified lead is then cast into
moulds or ingots. Cast iron moulds are used or ingot casting.
Casting
Mechanical and Manual Ingot casting mechanism is provided for ease of operation and
high-grade safety to the operators. Generally manual-casting system is provided with
smaller refining and alloying kettles.
Molten, refined, or alloyed lead is
pumped via heated pipes from kettles to a casting mechanism, which directs
a measured amount of lead into steel or cast iron moulds.
Drossing
During drossing operations, dross is
skimmed to the rim of the kettle and manually shoveled or spooned
into a container. Dross consists of Lead oxide
and oxides of other metal impurities like copper, iron, aluminium, antimony, tin
etc.
Pouring,
cooling of lead castings, drossing of lead oxides from the reservoir and casting
surfaces and other related activities emit some lead and dust fumes. Exhaust
ventilation for the castings and moulds is provided while pouring molten lead.
Magnabiz Corporation has the
technical expertise and experience to design systems for these operations
as per the user requirements and pollution control norms. Our endeavour is to provide best
solutions in most economic possible way.
