Remelted Lead Ingots are being produced from Raw Lead Battery Scraps Lead Scraps and other scraps of Lead in the specially designed Blast Furnace Rotary Furnace. The Scrap is obtained and is mixed with other reducing agents in the Furnace. Remelted Lead Ingot is used for making Pure Lead Ingots by Pyrometallurgical process. Remelted Lead or the crude Lead is the first production product in the Recycling System whose purity varies as per the raw material specifications. This Lead is obtained by reducing Lead Compounds into free Lead using Chemical heat treatment. These can be cast in big Bullions from Rotary Furnace or the Ingots from Blast Furnace. Remelted Lead Ingots, which contain about 97-99% Lead Metal with remaining Impurity Elements (Total 2-3%) as Antimony, Tin, Arsenic, Iron, Bismuth, Copper etc. This is commercially called as 'Raw Lead or Lead Bullion', which is further processed to Pure Lead (99.97 purity) and or Specific Lead Alloys. We supply remelted Lead blocks as per costumer’s requirement.

Our companies are competent enough in the supply of Pure Lead Ingot which are being produced from Raw Lead Bullion Remelted and Secondary Lead Ingots Lead Scraps through Pyrometallurgical process. The strength we have in our Refining Process is the purity Level we maintain minimum at 99.97% by weight but achieves purity level of 99.985% in most of cases. In our process by our experience we adopt many such features which ensure Dross-free & smooth top surface of each ingots. We dispatch after staking of 42 ingots in one bundle duly striped.

All processing industries generate waste. The quantities generated and their potential impacts depend on many factors, including the level of industrial development, the way in which wastes are managed, the existing state of the local environment and the capacity of the receiving media. The output of a Lead Recycling Plant can be categorized in to following standard forms: Solids - It is defined as the final by-product that is obtained after 2-3 run of the waste generated after recycling of fresh Lead bearing material. Sludge is obtained at the end of the process containing less then 2.5% of Lead content in it which is non – leach able in nature. These are to be disposed at proper Government approved Areas. Liquids - No Liquid waste is generated in our plant setup as we are using water for treatment of SOX gases which is further neutralized and re-circulated with in the system. Thus no drainage as effluents.onitoring & control of machinery Noise. Monitoring & control of Noise Emitted by transport vehicles.

Lead wool is made by scratching fine strands from the surface of a Lead disc. It is used for the caulking of joints in large pipes e.g. gas mains and in some specialist batteries. Lead Wool, a form of caulking Lead, is long, fine strands of chemical grade Lead which is twisted into 58”rope for use in various applications and is available in 5 lb. cartons or 50 lb. waterproof bags. It averages about 2-½ ft. to one pound. Lead wool is certified to meet Federal Specification QQ-C-40. The Lead wool is used to seal flanged connections, cast iron, cement and earthenware pipes, and apertures of walls and ceilings. Very good ductility of Lead ensures fast and easy filling and sealing of small slots too. It is also convenient for anti-radiation protection. The Lead resistance to aggressive environment is a warranty of long-term durability of seal. Lead wool, a loose rope of fibers, is produced by passing molten Lead through a fine sieve and allowing it to solidify. When forced into a crevice under considerable force, the fibrous rope cold welds into a homogeneous mass, forming a solid metal seal. This caulking process is useful where temperature or explosion hazards prohibit the use of flame heating. The gaps between Lead shielding sheets in nuclear submarines are often filled and caulked with Lead wool. It is more convenient to use than molten Lead for caulking purposes because it requires no heating or pouring. Lead Wool properly packed is ideal for caulking and makes a tighter seal than molten Lead which shrinks slightly after casting.

Alloying is technique of combining or mixing two or more metals to make an entirely new metal, for example mixing copper and tin to create bronze. The process of Alloying is entirely opposite of Refining but Technically it has some resemblance as both the process are temperature based chemical process where in one process some elements are taken out at regular intervals and in other some elements are mixed. The natural lubricity and wear resistance of Lead make the metal suitable, in alloys, for heavy-duty bearing applications such as railroad-car journal bearings and piston-engine crank bearings. Lead is also widely used as a constituent in solders. Most common solders are the Lead-tin alloys; melting temperature can be as low as 361°F. In its unalloyed form (defined by ASTM B29 as 99.85% minimum Lead), Lead is soft and weak; it requires support for mechanical applications. This "chemical Lead" is used primarily in corrosive chemical-handling applications such as tank linings. "Hard Lead" — Lead alloyed with 1 to 13% antimony — has sufficient tensile strength, fatigue resistance, and hardness for many mechanical applications. These alloys can be cast, rolled, or extruded and are especially suited for castings requiring good detail and moderate strength. Rolled antimonial alloys are harder and stronger than the cast alloys. Battery-plate Lead contains 7 to 12% antimony. Lead-antimony alloys with antimony contents of between 1 and 12% are used widely in the chemical industry for pumps and valves on chemical plants and in radiation shielding both for lining the walls of X-ray rooms and for bricks to house radioactive sources in the nuclear industry. The addition of antimony to Lead increases lead's hardness and therefore its resistance to physical damage without greatly reducing its corrosion resistance.

The external sheath of power cables and communication cables has to protect the internal elements from mechanical damage and from environmental influences. Lead cable sheaths have been extruded directly onto cable cores for more than 100 years, since the invention of cable sheathing by Borell in 1879. Today, approximately 10% of overland and underseas cables are sheathed with metal, usually Lead. The thickness of cable sheath is standardized and is usually between 1 and 3 mm the sheath has to be completely tight and protect the internal conductor and insulation layers against moisture as well as mechanical, chemical and thermal influences. Further requirements are: A narrow wall thickness tolerance is prescribed in the standard. The mean value should be at least equal to the nominal value. Stop marks (known as bamboo rings) can form when the press is stopped and reloaded. These marks are undesirable because of the associated wall thickness deviations.In Lead cable sheathing, liquid metal is poured into a vertical container. Usually, it is filled from an electrically heated crucible containing several tons of the melt through a floor valve with various flow systems at a maximum temperature of 450 C. The cast Lead should bond well with the discard from the previous filling on the die head to prevent possible defects from inclusions. Air blisters should not form during filling. The Lead is, therefore, usually filled under vacuum together with a lost head that is sheared after solidification at the top edge of the container. The metal solidifies in water cooled container under a small load applied by the steam within 5 to 10 minutes after which the extrusion process can begin.
