Gas Furnace Heat Treatment for LPG Gas Cylinder Manufacturing Equipments Body Manufacturing Line

LPG Cylinder Heat Treatment Machine Anneal Furnace for LPG Cylinder Manufacture Product Line    Product DescriptionIntroduction for heat treatment furnace      Continuous cylinder heat treatment nature gas heat treatment furnace is widely used for heat treatment of steel cylinder. The heating of the furnace is divided into two sections. One section is the heating section (horizontal); the second section is the high temperature section (horizontal).Parameter and requirements:1.Continuous heat treatment furnace: total length for this machine is 20 meters(furnace is 15 meters, loading & unloading holder is 5 meters). The furnace is welded by high quality section steel, the furnace is lined with high temperature resistant high alumina refractory firebrick, insulation layer is made of fiber and other thermal insulation materials. Overall, the high temperature furnace is light and of good insulation performance.2.Application: Cylinder normalizing heat treatment3.Specification: ISO Standard, cylinder weight:6kg/pc, 12.5kg/pc,25 and 52kgs Diameter of cylinder is from DN200-400mm4.Working efficiency: 200pcs/hour5.Entrance temperature: 30ºC6.Cylinder heating temperature: 900ºC±25ºC7.The max. working temperature of the furnace body: ≤1000ºC8.The temperature rise of furnace body surface is according to China industry standards.9.Parts of the furnace:10.Horizontal furnace body: 1 set11.Loading and unloading chain mechanism: 1 pair12.Nature gas control system(record containing): 1 set13.Flue gas and heat exchange system: 1 set14.Fuel type: nature gas 15.Fuel calorific value: 8500 Kcal / kg 16.The form of combustion apparatus: high-speed fuel burner17.Heating quantity and thermal load distribution: 8 pcs gas burner18.No. of burners in heating section:4 pcs burners, 230KW/pcs19.

No of burning nozzle: 150000Kcal, totally 8 pieces.2. Working temperature: 700 ± 25 degree3. Furnace chamberA.Furnace length: 32.5m, overall length including loading & unloading: 37.5m.Furnace liner lower part is high-temperature cast structure, upper part is heavy brick or cast module. Between the furnace body and furnace liner is insulating layer made from Aluminum silicate fiber cotton. To ensure the ability of keeping the temperature.B.Each section of furnace: L2500*W1350*H1450mm, inner hole size 650mm.C.Out shell is made from angle iron and steel sheets. The bottom is made from steel structure, channel steel, with steel sheets, due to the high pressure.Between each section of furnace, they are connected by angle steel flange, easy to install and adjust. C. Frequency Electrical Furnace:  I. Frequency heating principle:Frequency heating is using frequency power to change 380V, 50Hz power current into the suitable frequency current by rectification and contravariant. Input this current into resonant tank composed by the heating furnace, to make the furnace coil produce alternating magnetic field, while the pre-heating metal material stay in the alternating magnetic field, the material will produce the alternating current and heating by itself, high hot efficiency and low energy consumption.Feature:Frequency induction heating power factor≥96%, has automatic impedance adjustment function, the performance of energy saving is obviously.Power output is steady, heating temperature is easy to control, good consistency to improve the heating quality.Good diathermancy, magnetic field has a good permeability to the metal workpiece, it's not heating conduction, so the temperature difference of workpiece movements is small and improve the products' quality.Temperature measuring system closed-loop control heating power, the precision of temperature is high.Automatic impedance adjustment and automatic frequency adjustment function, inspecting system impedance transformation caused by the cylinder from cool to hot during the whole heating process automatically. Adjusting the output parameter automatically and making the whole heating process stay in energy-efficient state, saving more power. II.
