vacuum furnace
Vacuum furnace is mainly used for the melting of metal materials (such as stainless steel, nickel-based alloy, copper, alloy steel, nickel-cobalt alloy, rare earth neodymium iron, etc.) under vacuum or protective atmosphere conditions. It can also be used for the vacuum refining of alloy steel an...
Several important concepts in vacuum technology
At one atmospheric pressure, the molecular density of air n = 2.7 × 1019 / cm3. Air is a mixture of gases, the relative molecular weight of which is calculated by the proportion of gas molecules. The molecular weight of nitrogen is 28.016, the volume ratio is 78.1%; the molecular weight of oxygen...
Perfomance analysis of industrial vacuum furnace
The performance of the vacuum furnace is mainly reflected in the following parameters: degassing, extraction speed and ultimate vacuum. degassing Degassing is the phenomenon of slow evaporation of materials in vacuum, which is the main problem to be considered in vacuum performance. In a vacuum s...
How does vacuum furnace carry out heat conversion
The vacuum furnace is a vacuum environment with negative pressure formed in the closed furnace body, which is filled with heat medium water. The heat medium water is heated by combustion or other means, evaporated and condensed by the heat medium water to the heat exchanger, and then the water to...
How to clean the heat treatment materials of vacuum gas quenching furnace
How to clean the heat treatment materials of vacuum gas quenching furnace? The following steps are required to clean the heat treatment materials of the vacuum gas quenching furnace: 1. Put the cleaning parts into the furnace through the basket, and tighten them after closing the door. 2. When th...
gas quenching vacuum furnace
Vacuum gas quenching furnace is mainly used for vacuum annealing and aging process of Cu, Ni, be, Cr, Ti, Zr, Nb, Ta, W, Mo and other metal materials and alloy materials, high-speed steel, cold and hot die steel, stainless steel, elastic alloy, high-temperature alloy, soft magnetic material, stai...
vacuum heat treatment furnace leak detection
The oil quenching vacuum heat treatment furnace produced by our company is an example of leak detection on site. This paper introduces the leak detection method based on theoretical analysis and judgment in the absence of special leak detection instrument. Leak detection of vacuum heat treatment ...
High vacuum furnace
High vacuum furnace is a national standard energy-saving heat treatment furnace, super energy-saving structure, using all fiber structure, energy saving 30% – 40%. The high vacuum furnace is mainly composed of furnace body (including furnace lining), electric heating device, vacuum device (...
Vacuum carburizing heat treatment process
The results show that the flatness is not well controlled and the flatness is poor. The mounting method is improved, the hanging mode of h-shaped material rod is adopted, and the width, groove depth, wall thickness and other parameters of material rod are constantly improved, which can improve th...
Vacuum Furnace Characteristics
(1) Strict vacuum sealing: it is known to all that the vacuum heat treatment of metal parts is carried out in a closed vacuum furnace. Therefore, it is of great significance to obtain and maintain the original air leakage rate of the furnace and ensure the working vacuum of the vacuum furnace to ...
