The Influence of Vacuum Brazing Heating Rate on Brazing Quality
Heat exchanger (also called heat exchanger or heat exchange equipment) is a device used to transfer heat from hot fluid to cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer. When the heating rate is fast, the surface color of the pa...
SPS spark plasma sintering system
As a new and effective rapid sintering technology, spark plasma sintering (SPS) has been applied to the research and development of many kinds of materials. It combines the advantages of plasma activation and hot pressing, such as fast heating rate, short sintering time, rapid cooling, adjustable...
7 Types of Annealing Process
Various energy-saving annealing processes such as low-temperature annealing, water-blast annealing, rapid softening, and isothermal spheroidizing annealing performed by domestic counterparts, compared with traditional high-temperature and long-term annealing processes, the new annealing process s...
vacuum tempering furnace heating process attentions
As we all know, vacuum tempering furnace is mainly used for tool steel, die steel, high speed steel, ultra-high strength steel, titanium alloy and other materials after vacuum quenching, vacuum tempering after solution treatment, recrystallization annealing and vacuum aging of non-ferrous metals....
vacuum heat treatment technology
Vacuum quenching advantages Vacuum heat treatment technology was used earlier in foreign countries. In 1968, Hayes company of the United States and vacuum Research Institute of Japan successively developed vacuum quenching oil and water quenching agent. As a result, vacuum quenching technology ha...
The reasons of the poor vacuum degree in vacuum furnace
The vacuum furnace cannot reach the vacuum degree: it may be that the pumping capacity of the vacuum unit is not enough, it may be that the leakage rate is too high, or both. After evacuating the vacuum chamber to a certain vacuum state, close the vacuum valve. If the vacuum count rises quickly, ...
die steel and high-speed steel material heat treatment
Several different types of die steel and high-speed steel material introduction and heat treatment knowledge 1.3343 High-speed steel characteristics introduction Gritz 1.3343 high-speed steel is tungsten-molybdenum series general high-speed steel. 1.3343 high-speed steel has the advantages of fin...
Vacuum brazing technology and vacuum furnace equipment
Vacuum brazing technology and vacuum furnace equipment introduction Brief introduction of vacuum brazing technology development Vacuum brazing refers to the heating of the workpiece in a vacuum chamber, and is mainly used for welding products that require high quality and easily oxidized material...
Vacuum brazing process of aluminum alloy radiator for BMW engine
Aluminum alloy is widely used in aerospace, construction, electrical appliances, automobiles, ships and other sectors due to its light weight, good corrosion resistance, and excellent thermal and electrical conductivity, and its usage is increasing. It has long been considered as a heat exchanger...
Aluminum vacuum brazing technology introduction
Speaking of aluminum vacuum brazing, we must first know the mechanism and process characteristics of vacuum aluminum brazing: During vacuum brazing of aluminum alloy, the oxide film on the surface of the product affects the wetting and flow of the liquid solder. During the vacuum brazing process,...
