| | Heat Treatment Furnace
Applications : 1 Annealing 2 Normalising 3 Hardening 4 Solution Treatment Heating 5 Forge Heating 6 Tempering 7 Aluminum Solutionising 8 Stress Relieving 9 Ductile Iron Full Annealing. Auto cycle control 1 Ramp, Soak, Cool ..... 8 Steps Profile 2 10, 20 Profile Memory 3 Multi Input Multi Output (MIMO) 4 PID Controlling Action. 5 Micro processor based programable controller. 6 one burner, one thermocouple forms one pair as zone, thus multi zone control 7 Digital display for time temprature graph online with USB pendrive for data storage, Wired lan PC connectivity for real time graph printing Firing 1 High Velocity Short Flame Burner 2 Direct On/Off pulse firing effect. 3 Smokeless perfect combustion The furnaces are calibrated for uniformity as per API 6A Standard ( The Temperature Difference Between Highest & Lowest Points at Stabilised Conditions should not be more than 13ºC.) Mechanization 1 Trolley - movement by geared motor with brake. 2 Door - movement by geared motor with brake, counter weighed, 3 Door Lock Unlock - innovative,Pneumatically operated instant latching unlatching for perfect sealing
Construction: 1 Strong rigid construction 2 Heat resistant grade CI castings at door and frame, bogie and furnace interface eliminates warpage. 3 Railway rails for load bearing under temperature. 4 Double sealing minimising heat losses.
Insulation : 1 High temperature high density ceramic fibre modular lining. 2 Self supporting U-fold door lining.
Recuperator :1 All fuel fired furnaces are equiped with recuperator to recover the heat from flue gases by preheating combustion air. By thumb rule a rise of 150 degree C in combustion air 7.5% heat is recovered.
PLC control : 1 Large furnaces handle high value materials, it is essential to install PLC for opration to avoid manual errors. 2 PLC checks each & every operation prior to loading of materials called booting to ensure air/gas/power etc. are within the specifications & all the sensors are in working condition . 3 PLC monitors each & every operation during auto cycle for supply conditions, flue temperatures burner operations any deviation is automatically notified audio visualy & through SCADA 4 PLC keeps event history for the record
Control Panel : 1 Aesthetically powder coated control panel. 2 Electrical switch gears for drives, burners. 3 Status indication and control. 4 Burner sequence controller and flame failure device. 5 Programmable startup, burner, temperature controlling system.
Calibrations : 1 Thermal survey as per API 6A Standard. 2 All measuring instruments calibrated to national traceability
