we Kalyani enterprises manufacturing Electrical Gas Carburizing furnace. Pit type sealed retort furnaces are of a cylindrical design vertically erected with a positive sealing mechanism on top in order to contain and preserve heat and atmosphere during a process cycle. The job or charge is loaded into a retort which functions as the chamber of the furnace and the retort is heated externally electrically. Pit furnaces like these are used in general engineering and metallurgical applications for carburizing, nitriding, carbonitriding, nitrocarburizing, hardening, tempering, annealing and also in process industries like coal tar processing, separation of titanium and magnesium from ore etc. Special processes such as aluminium and titanium heat treatment can also be done. In process industries, these furnaces can also be used in high-pressure applications with temperatures from 800°C to 1200°C and pressure ranging from 400mm water column to 9 bar. These are often laid in a pit to make most of the space available and charges can be loaded and unloaded easily. These are manufactured considering working controlled atmospheres with inlets for diffusion and distribution of cracked ammonia, hydrogen, LPG, methanol, argon, nitrogen and other process fluids. Kalyani manufactures and sets up complete automated process plants also. Temperature control, fluid dissociation, gas penetration and dosing can all be taken up for automated operation.

Kalyani Enterprises manufacturing Heat Cleaning Oven For Powder & Paint CoatingsAt Pollution Control Products, We Offer to Burn Off Ovens That Are Effective In The Removal (Sometimes Called Stripping) Of Paint And Powder Coatings From Metal Parts Including Hooks, Racks And More. Below Is A Common Application Scenario For Our Ovens. THE PROBLEM: Paint And Powder Coating Operations Need A Safe, Fast And Efficient Way To Keep Their Paint And Powder Hooks And Racks Pristine To Maintain Product Quality And Profitability. Most Paint And Powder Coating Today Is Done Through An Electrostatic Coating Process. The Paint Or Powder Is Charged Negatively When It Comes Out Of The Application Sprayer, And The Part Being Coated Is Charged Positively, Thus Ensuring A Good Bond And Reducing The Amount Of Paint Or Powder Required To Coat The Part. Ultimately Paint And Powder Coating Buildup Reduces The Electrical Contact Resulting In Improper Coating And Wasted Paint Or Powder Coating. Not Only Must The Hooks Be Cleaned Regularly, But The Painted Parts May also Need To Be Stripped Of Old Paint Or Powder Coating So They Can Be Recoated Properly. THE SOLUTION: Cleaning Furnaces (Burn-Off Ovens) Have Been A Major Component Of Paint And Powder Coating Operations For Many, Many Years. The Furnace's Fully Automated Cleaning Cycle Greatly Reduces Labor Costs, Extends The Life Of Hangars And Racks And Helps Maintain A Moving And Clean Finishing Line. Excessive Coatings And Buildup On Hooks, Racks, And Metal Parts Are Vaporized Into Smoke - Pyrolyzed At Temperatures Of 370-430°C. The Resulting Smoke And Emissions Generated Are Drawn Through A Powerful Afterburner Operating At Approximately 430°C, Incinerating The Smoke Completely, Leaving Only Invisible, Odorless And Harmless Water Vapor And Carbon Dioxide To Exit The Exhaust Stack. Only Inorganic Ash Remains On The Parts, Which Is Easily Removed With A Water Rinse. The Cleaned Hooks And Racks Are Then Ready To Be Returned To Service.

For annealing and hardening of larger parts, for example heavy cast parts or tool steel dies to temperatures between 800 °C and 1100 °C, we recommend our bogie hearth furnaces with radiation heating. The bogie can be loaded outside the furnace. When the design includes an electro-mechanical lift door and a motorized bogie, the furnace can be opened while hot and the load can be removed for cooling or quenching. When several bogies are used together with a second door or bogie transfer system, one bogie can be loaded outside the furnace while the other bogie is in the furnace. This shortens process times and the residual energy of the furnace can be used when the new charge is heated. Tmax 900 °C or 1200 °C Dual shell housing with rear ventilation, provides low shell temperatures Swing door hinged on the right side Heating from five sides (four sides and bogie) provides for a optimum temperature uniformity Bogie heating receives power via blade contacts when driven in Available In LPG/PNG/HSD/ELECTRIC capacity from 0.5 Mt to 15 MT
