The parts of the vacuum brazing furnace need cleaning steps

The parts of the vacuum brazing furnace need cleaning steps

Vacuum brazing furnace need cleaning components in (1) first trough soaking in the preheating, again in ultrasonic cleaning tank (2) cleaning, use of ultrasonic cavitation effect to accelerate the pollutants dissolved and dissection, then rinse in cold rinse tank (3) by ultrasound, rinse off residual dirt, and make the workpiece cooling, the bigger the temperature difference between workpiece and solvent vapor is more conducive to the condensation, vapor phase cleaning effect is better. Finally in the solvent vapor layer (bath wash tank) RGL, rinse hot solvent vapors generated encounter cold condensation, solvent vapor into liquid, wetting, dissolve the contaminants on the surface of the workpiece, and like rain drops, and take away pollutants. When the workpiece temperature of solvent vapor temperature, condensation, no longer no longer drops on the surface of the parts, said end of vapor phase cleaning. Finally, the workpiece is put forward to leave vapor layer to the frozen area, artifacts slightly stay which is completely dry. Because the steam is clean, clean process without secondary pollution, so it is a completely clean cleaning process, can achieve very high cleanliness.

Maintenance of vacuum brazing furnace

Maintenance of vacuum brazing furnace

Continuously operating on a daily basis - with no filler metal with vacuum brazing furnace to various parts of the vacuum brazing furnace, inevitably lead to some vacuum brazing furnace charge fly all the damage to the heating elements and heat shield. If not timely maintenance, vacuum brazing furnace metal deposition, will soon be corrosion damage to the heating element, or produce local overheating, or make the heating system is broken one or more of the phase. That leads to the temperature of the inhomogeneity, in batch vacuum brazing furnace production, this kind of situation is often not noticed. Heating element of repair is the easy, it is not the same as heat insulation screen damage.
If heat insulation screen USES the key persons, as long as the screen with a thin layer of ink stone protection can make the vacuum brazing furnace metal splash damage down to the most. Vacuum brazing furnace metal and graphite surface wetting and bonding, not simply in the form of beads drops roll to the cold of the furnace area. After completion of these particles in a vacuum brazing furnace, also not harm can easily be removed.

Simple understanding of vacuum brazing furnace

Everyone's understanding of vacuum brazing furnace how many? In order to make people more about the product master, we'll give you a brief introduction of below!
Vacuum brazing furnace is the large-scale equipment, heat treatment can be vacuum brazing, vacuum annealing, vacuum aging and other processing. Programmable multiple different procedures, it can control and into hundreds of heat treatment curve points, six points up, down, left and right sides, front and rear area temperature control, there are more and single point temperature recorder and over temperature protection device,  vacuum furnace temperature uniformity can be controlled in less than 3 ℃, the other with the installation of high purity nitrogen high flow of strong cold. The equipment has a large amount of furnace charging and high efficiency, have special request for complex parts and parts no need for supplementary processing products.

Vacuum Brazing for Tungsten Carbide and Cobalt Titanium 40Cr Steel

Vacuum Brazing for Tungsten Carbide and Cobalt Titanium 40Cr Steel

Cobalt tungsten titanium carbide and carbon steel 40Cr vacuum brazing welded. Vacuum brazing method is suitable for mass production of carbide cutting tools and drilling of carbide drills and the like.
Once heated to complete multiple blade brazing of carbide cutting tools, we have a higher efficiency of brazing. Most carbide tools welding methods previously embedded in the carbon steel or low alloy steel substrate use is closely related to the use of performance cemented carbide welding process, the welding performance has a direct impact on the use of carbide effect. When vacuum brazing tungsten carbide cobalt titanium, welding residual stress must be minimized. Measures must be taken to reduce the braze welding stress can be taken to reduce brazing temperature, preheat and slow cooling, use plastic good solder, plus compensation pads, and other measures to improve the joint structure. When a large area of hard alloy brazing, regardless of intensity, should take special measures to reduce welding stress and prevent cracks.

Good performance of vacuum brazing furnace

Good performance of vacuum brazing furnace

Vacuum brazing furnace to maintain excellent soldering quality depends on the performance of the vacuum unit. Often, vacuum pump needs to be careful not to think that "you never turn it off, it will run forever." If vacuum maintenance crew at the time, on weekends and holidays shutdown, more economical to do so. Otherwise, if still idling at the weekend, mechanical pump will be stuck and difficult to start again. The results of our experiments show that this method can save a lot of electricity. Due to the lack of water or overheating, mechanical pump overheating, and noises.
It's better to keep the water temperature is 140. (60 ~ 150 F a 6 ℃), the use of portable devices to pump oil filter once a week, check the oil level and take sample, check the oil quality by feeling and appearance. A few years ago, we have found that the mechanical pump with high quality oil is more economic. The cost of high quality oil is generally more than three times of industrial oil, and keep the pump qing jie time is five times the sustainable. Live a door should be changed every three months and spring. Stainless steel spring live longer.
