SPS spark plasma sintering technology introduction
Spark plasma sintering (SPS) is a rapid sintering method that uses axial force and pulsed current to heat and solidify powder at a high speed under low atmospheric pressure. This heating method can apply a very high heating temperature, can greatly increase the density (see the figure below), and...
Vacuum air quenching heat treatment process for ring die of feed pelletizer
The overall quenching of the ring die of the feed pelletizer generally refers to the heat treatment in an electric furnace or a salt bath furnace in an atmospheric environment. However, in the past 20 years, more and more foreign feed machinery manufacturers have begun to use vacuum furnaces to q...
Brief introduction of stainless steel ring die for feed pellet equipment
Ring die pelletizer is one of the four main hosts of feed machinery, and it occupies a very important position in the process of feed processing. The ring die is the core component of the granulator and a high-value vulnerable part of the granulator. Its quality directly affects the economic bene...
Prospects of Heat Treatment Process in Vacuum Furnace
What is vacuum heat treatment processing technology? Refers to a new type of heat treatment technology that combines vacuum technology and heat treatment technology. Among them, the vacuum environment in which vacuum heat treatment is located refers to an atmosphere environment below one atmosphe...
Comparison of several sintering methods of silicon carbide
Silicon carbide is a good corrosion-resistant material, and we can use it to make ceramics and other products. When using silicon carbide to make ceramics, there are many sintering methods, and the appropriate sintering method can be selected according to the specific processing environment to im...

Why do everyone like to use vacuum heat treatment furnaces from Shanghai Gehang Company? Mainly because the VOGQ series oil quenching vacuum furnace has the advantages of rap...
vacuum brazing furnace performance characteristics
The vacuum brazing furnace includes single-chamber horizontal furnace, double-chamber semi-continuous furnace, three-chamber continuous furnace and so on. This equipment is more suitable for vacuum brazing of stainless steel, titanium alloys, hard alloys, and high temperature alloys. In order to ...
How to choose graphite rod heating element for vacuum furnace
The vacuum furnace should use graphite rods with good red heat uniformity in the heating part as the heating element. Instructions for the use of graphite rods for vacuum furnaces 1. Use graphite rods with good red heat uniformity in the heating part. The poor red heat uniformity of the rod will ...
How to choose the heating chamber of the vacuum furnace and use the vacuum degree
The types of vacuum furnace heating chambers are: Graphite reflective screen: Generally, there are two kinds of graphite materials, hard felt and soft felt used in vacuum furnace, which are suitable for quenching, tempering and annealing of general steel. High temperature brazing, powder metallur...
vacuum furnace introduction to the design principle
The vacuum furnace can be explained from a professional point of view. It can be understood as follows: the application of a vacuum system (a vacuum pump, vacuum measuring installation, vacuum valve, furnace body, control system and other components carefully assembled) in a specific space of the...
