What is the difference between a vacuum furnace and an atmosphere furnace?

Vacuum furnace and atmosphere furnace are two commonly used heat treatment equipment in the heat treatment industry, and there are significant differences in many aspects. Let's take a look at the differences between vacuum furnace and atmosphere furnace in the following aspects!bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

1. Working principlebbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Vacuum furnace: A vacuum furnace is a device that heats up in a vacuum environment. It uses a vacuum system (including a vacuum pump, vacuum measuring device, vacuum valve, etc.) to discharge some of the substances inside the furnace cavity, making the pressure inside the furnace cavity less than one standard atmospheric pressure, thereby achieving a vacuum state. In this state, heating work can lower the boiling point of water, accelerate drying speed, and eliminate phenomena such as oxidation and decarburization on the surface of the workpiece during the heating process, maintaining the brightness and cleanliness of the workpiece.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Atmosphere furnace: An atmosphere furnace is a device that heats up under normal conditions or in a controlled atmosphere environment. It can introduce gases such as nitrogen, hydrogen, carbon dioxide, argon, carbon monoxide, etc. to meet the processing needs of different products. The atmosphere furnace changes the physical and chemical properties of materials by controlling the atmosphere, temperature, and time.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

2. Structure and CompositionbbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Vacuum furnace: usually composed of furnace body, furnace door, heating element, insulation element, control system, vacuum system, and power supply. The vacuum system is its core component, capable of pumping a high degree of vacuum. The structure of vacuum furnaces is mostly circular, which is conducive to forming a stable vacuum environment.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Atmosphere furnace: The structure of an atmosphere furnace is relatively simple, mainly composed of a furnace body, an inner container moving frame, a temperature control system, a resistance wire heating system, and a display system. The furnace door is equipped with a cooling water system, and there are several inlet and outlet valves on the furnace body to control the inflow and outflow of atmosphere. Atmosphere furnaces are generally square shaped structures that are easy to operate and maintain.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

3. Application scopebbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Vacuum furnace: mainly used for vacuum brazing of stainless steel heat exchangers, stainless steel insulation cups, oil coolers, etc; Brazing of non-ferrous metals, titanium alloys, high-temperature alloys, and hard alloys; Vacuum tempering treatment of materials such as tooling steel, bearing steel, high-speed steel, etc; And vacuum brazing of aluminum products such as aluminum alloy heat exchangers.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
Atmosphere furnace: suitable for industrial and mining laboratories, major university laboratories and other places, providing data for chemical analysis and material determination. At the same time, atmosphere furnaces are widely used in metallurgy, heat treatment, grinding tools, abrasives, and glass industries for high-temperature sintering, dissolution, and other processes of materials.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

4. Price and CostbbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The price of vacuum furnaces is usually much higher than that of atmosphere furnaces. Due to the more complex structure of the vacuum furnace and the need for high-precision vacuum and control systems, its manufacturing cost and selling price are relatively high. Generally speaking, the price of vacuum furnaces on the market is over 200000 yuan.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The price of an atmosphere furnace is relatively affordable, and a small atmosphere furnace may only cost around 20000 yuan. This makes the atmosphere furnace more cost-effective in meeting general processing needs.bbJMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
