Aluminum Billet pre-heating furnace with shear
1.Direct fire billet heating
2.Heating fast(20mins)
3.Accurate control(PLC)
1. Functions
SY-PSL series billet fast spray heating furnace is continuous gas heating furnace for billet heating which for billet fast and direct heating before extrusion.
2. Heating principle
The furnace adopted LPG or natural gas as fuel to heat the billet fastly.The gas adjust to suitable pressure thru.pressure regulator and assist fan adjust to suitable pressure thru.ventilation door,after mix thru.premixer that spraying from nozzle then the nozzle ignation to realize the furnace heating. After ignition succeed monitoring by UV magic eye if fire failed or put out that the monitor will alarm with light bright and re-ignition after malfunction remove.
The furnace setting several pressure switch for monitor the pressure such as gas,assist fan and preheating cycle fan if the above pressure out of control that unable work normally.
3. Structure
The furnace consist of 1.billet up loader,2.billet output system,3.preheating zone, 4.spraying heating zone, 5.spraying heating system, 6.spraying preheating hot cycle system,7.Insert type thermocouple temp.testing sytem. 9.protection device and 9.elec.cabinet.
1.Billet up loader:Be consisting of billet up power drive system and storage table.
2.billet output system:Be consist of billet output power drive and billet transfer device.billet output system take the billet from furnace and transfer to extrusion press thru.billet transfer system.
3.preheating zone: there are several spray air-pipe arrange inside the chamber and most of hot air for preheating cycle and little exhaust gas discharge from smoke tube which in the bottom of furnace. There are rows of rolling which made of heatproof plate under the chamber for billet transfer.
4.spraying heating zone: General consist of several heating zone which up to the quantity of billet diameter and quantity. inside the chamber have gas nozzle at both side. The nozzle inside the chamber made by heatproof stainless steel which has long life. There are rows of rolling which made of heatproof plate under the chamber for billet transfer.
5.Spraying heating system: Be consist of pre-mix system,pressure adjust system, ignition device and fire monitor device . The system is the core part of furnace.
6.Spraying preheating hot cycle system: the system at the area of preheating zone, top of furnace have hot air cycle fan ,the enter and exit of fan connect with furnace chamber .smokebox collector and spraying pipe to combine with preheating fan cycle system.
7.Insert type thermocouple temp.testing sytem.:reasonable structure design can remove the from burner gas to test billet actual temperature accurate.its the main structure of billet heating and temperature control .
8.protection device
Each furnace have safe anti-explosion hole which for pressure discharge safety while the pressure unstable or increase suddenly.it is the funcation of protecting equipment and operator.
9.Elec.cabinet.
Electricity cabinet:power drive cabinet and operation cabinet,arrange for the side of furnace and furnace operation position.
