About Steel re-Rolling Mill Steel Re-rolling is a major steel section and bar producing technology used in India and abroad. Since its inception in India with setting up of first re-rolling mill in Kanpur in 1928, this technology has contributed significant steelmaking capacity in secondary steel sector in India. Air Pollution Depending upon the fuel used in heating the furnace of a Steel Re-rolling Mill, the characteristics of flue gases may vary. For coal fired furnaces they may consist of gaseous as well as particulate pollutants. For oil or gas fired furnaces, these flue gases may consist of just gaseous pollutants. The flue gases may also be corrosive in nature. Selection of Technology for Air Pollution Control Device Selection of Technology for Equipment in an Air Pollution Control System in case of a Steel Re-rolling Mill depends upon the fuel to be used : a. Scrubber based System for Oil / Gas Fired Furnaces b. Cyclone and Scrubber based System for Coal Fired Furnaces About Scrubber based System for Oil / Gas Fired Furnaces Characteristics of Air Pollution Generated In Induction Furnace 1 Pollutants : Dust & Gases such as NO , SO , CO, Co x 2 2 2 Concentration : SPM - 1200-1500 mg/Nm (Maximum, in coal fired) 3 So - 800-1000 mg/Nm 2 4 NO - 20-50 mg/Nm x 5 Temperature : At Suction Point: 250-300 C 6 Nature of Dust : Slightly Sticky, Non Abrasive and Non Explosive Control Practices The control practice adopted in controlling air pollution in this industry mainly depends upon following parameters : 1 Dust/Gas Concentration at inlet 2 Discharge Standards 3 Temperature of Flue Gases 4 Nature of Pollutant i.e. Dust (Particulate) or Gaseous 5 Nature of Dust i.e. Sticky, Abrasive 6 Nature of Gases i.e. Corrosive, Non Corrosive Working of Equipment 1.

The Air Max is for intercepting all kinds of dirt coming into indoor from outside. By using HEPA filter.
This unit features a deep-bed activated carbon filter that uses a special carbon blend to remove voc's (volatile organic compounds) which are the most common airborne chemicals in the home. The unit also includes a medical-grade hepa to remove 99.97% of airborne particles (pollen, dust, mold, bacteria, viruses, pet dander) down to 0.3 microns in size Activated carbon filter, 2.5" depth, medical-grade hepa, pre-filter. 18 lbs. Or activated carbon. 50lbs
About Lead Refining Lead recycled from used lead acid batteries or other sources (Secondary Smelting) via the Mini Blast Furnace or Rotary Furnace route, contains lot of contamination and undesired components. On the other hand, Lead required for battery manufacturing is either soft Lead with 99.97% purity or hard Lead of varying Antimony compositions. In order to make quality of lead suitable for its different uses, different variations of pot melting processes are employed. These include Re-Melting for removal of slag, Refining” for attaining required purity levels and Alloying for producing various alloys of lead. The equipments used are the same, the consumables and the processes, however, differ. Description of Melting Pot The Melting Pot (or Refining Pot or Alloying Pot, as it is variously called), is a mechanical mixing device with a pot and a heating arrangement. The inner pot is made of heavy MS plate with dish end bottom. It is placed within a jacket of refractory bricks, which in turn, are protected by an outer cover of MS plate with reinforcements. The pot is covered at the top with opening for feeding lead ingots and is provided with an electro-mechanical mixer. At the bottom, a heating source, usually an oil fired burner, is provided to heat the pot and to melt the lead. Once lead melts, impurities are skimmed and removed and any consumables required are added. Lead is then drained from the pot through an outlet pipe and valve. Capacity of such pots depends upon the requirements of particular units. Standard pot capacities made are from 4.0 TpB to 20.0 TpB. Higher capacity pots are also manufactured as required by any particular establishment. A typical 10.0 TpB Refining Pot has the following standard sizes and specifications: Diameter (ID) 1150mm Height 1250mm (Dish Depth of 200mm) Flange Width 350mm Outer Shell Diameter 1900mm Stirrer MoC & Dia SS-304 & 75mm Stirrer Motor 5.0 HP x 960 RPM Outlet Valve Size 40mm Burner Diesel Fired Fuel Consumption Range 8-18kg ltr Melting pots are installed both with and without accessories which may include Ingot Casting Machine, Ball Making Machine (where Ball Mills are installed down the line), Air Pollution Control Systems, Jib Cranes etc. Production Process Melting Processes have been grouped as Re-Melting Process Refining Process Alloying Process Re-Melting Process This process is undertaken for value addition to the recycled lead from furnaces. Lead is melted in the pot and major impurities are skimmed from it to make it saleable in the market. Refining Process Lead is melted in the pot, additives such as Sulphur, Wooden Powder and Coke Breeze are added and mixed gently followed by dross removal. Thereafter, Tin is added to remove Copper and temperature is increased to 550-6000C. Further, additives such as Sodium Nitrate & Caustic Soda are added to remove Antimony. This process is repeated to get the desired purity of lead. Alloying Process Lead is melted in the pot, additives such as Sulphur, Wooden Powder & Coke Breeze are added and mixed gently followed by dross removal. Thereafter, Tin & Antimony are added to the liquid metal to get the desired grade of Lead. Air Pollution Control Device for Refining Pot Melting processes lead to generation of air pollution at the following stages Initial heating and melting generates fumes Drossing with sulphur, wooden powder and coke breeze generates lot of smoke and dust particles Further heating for Refining and Alloying with different chemicals generates fumes and dust particles. Hence, to meet various goals of maintaining employees' health, factory environments as well as regulatory requirements, it becomes imperative to get high end Air Pollution Control Systems to be installed with the Melting Pots. Air Pollution Control Device for Refining Pot Dust : 500-600 mg/Nm Temperature : 60-80C G Gases : Fumes and Dust Discharge Characteristics required as per Norms Dust : Less than 50 mg/Nm Lead ( Pb) : Less than 10 mg/Nm Temperature : 50-60 C Gases : Not Detectable Selection of Technology for Air Pollution Control Based on the Parameters and the Standards mentioned, the following technology is adopted for Air Pollution Control System in Melting Pot: Pulse Jet based Bag House Filtration System Details of Air Pollution Control Device with functions Aerodynamically designed suction hoods are provided to capture flue gases generated at source itself. Duct & Bends Ducts and bends are required to convey flue gases from point of suction to final top of the chimney and connect various equipments like suction hood, bag house, ID fan and chimney. All bends and reducers are aerodynamically designed and have provision of manhole cleaning mechanism. Bag Filtration System: It is used for final filtration of flue gases to remove fine dust particulate matter using Pulse Jet Technology. Treated gases from all the bags are collected at top of bag house and passed through ID Fan to exhaust the same to chimney. The dust is collected at bottom of hopper and is discharged through Rotary Air Lock Valve.
