Vacuum brazing furnace mainly Outlines and performance

Vacuum brazing furnace mainly Outlines and performance

Vacuum brazing furnace in vacuum arc of high temperature melting can make metal degassing, oxygen, and the process of removing impurities, pure metal billet is achieved. Under the action of molten metal in the water cooled copper crucible cooling solidification, as a result, high melting rate and the precise control of arc heating area, can guarantee the consistency of the direction of the molten metal solidification, and prevent solidification macro segregation and reduce the number of micro segregation, greatly improving the solidification of the ingot metal performance.
Vacuum furnace is through the material or parts under the vacuum state according to the technical process heating, cooling, to achieve the expected performance of a process. Vacuum furnace Namely in the condition of vacuum, heating up a set of components to the filler metal melting point temperature above, but below the substrate metal melting point temperature, with the aid of filler metal to wet and flow of metal in the matrix form of weld a welding process. (brazing temperature in different material varies) vacuum furnace under vacuum condition, heat the metal powder products, make the adjacent metal powder grain by adhesion and diffusion effect and a method of burn into parts. Vacuum furnace Mainly applied to metal materials and magnetic treatment.

Simple understanding of vacuum brazing furnace

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, 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.

The use of vacuum brazing furnace in good condition

The use of vacuum brazing furnace in good condition

Using gas, liquid hydrogen through outdoor of finned tube evaporator liquid tank evaporation, and concession road into large indoor air tank, in the furnace need to provide a large number of gas during the forced air cooling. Although gas supply manufacturers in the liquefied gas tanker exit gas purity of 9.998%, but according to the requirements of technical conditions should be checked at the entrance of each furnace gas dew point.
Asked dew point average for a 65 "F (18 ℃). Every six months a leak test should be made for the whole system to the root to the end, the vacuum brazing furnace running just is the result of users continuously maintained. In today's world, success is only a compromise between the gain and loss and efficiency. Users are concerned about the vacuum brazing furnace good used condition.

The vacuum brazing furnace can be adjusted according to customer's requirements

The vacuum brazing furnace can be adjusted according to customer's requirements

The following parameters for the standard configuration parameters, can be adjusted according to customer's requirements.
1, vacuum brazing furnace can match or external type fast cooling system;
2, can match the PLC programmable controller and graphic operation terminal (touch screen) control system;
3, according to the requirement of the vacuum oil diffusion pump, ultimate vacuum can reach 10-3 pa;
4, vacuum brazing furnace adopts special material selection and design of the heating element and heat insulation screen and sintering temperature can reach 2000 ℃ or more;
5, slightly negative pressure sintering system: in sintering stage a slight negative pressure value can be set, realize the constant pressure sintering furnace, improve the product density, improve the quality of sintered products.

Proper use and maintenance of vacuum brazing furnace

Proper use and maintenance of vacuum brazing furnace

Vacuum brazing furnace popularity of users and manufacturers are favorable, there is a lot to choose from a furnace, vacuum furnace products have been flooding the market. Vacuum brazing equipment is usually automatic feed, fully automated, does not require much training or through face that can master the operation. In fact, as long as strict vacuum care operator invited observe the rules, timely and pressing the button switches to operate. In addition to notify maintenance personnel to load, run, and uninstall device features the device is not normal, but the operator does not need to do any work. With different machining tools, without having to change tools, lubricants do not give on the part.
However, for new users, and these conditions are liable to be misunderstood, but also easily lead to false sense of security, when you have been forced to wait until then submit maintenance application. Specialized vacuum to less experienced users with a new maintenance problems. Vacuum brazing furnace for brazing heat treatment for more than just wear. Without regular maintenance, new stove and soon there will be a variety of problems, resulting in a vacuum furnace disabled.

Vacuum brazing furnace main use

                                            Vacuum brazing furnace main use
              
Vacuum brazing furnace, it is a kind of used for metal brazing and bright heat treatment equipment. Suitable for mass production of small and medium-sized stainless steel parts (tableware, cutting tools, hardware, etc.), such as martensite stainless steel bright quenching, tempering, austenitic stainless steel bright annealing.
   Main use: vacuum brazing furnace is mainly used for auto filter refrigeration parts, aerospace industry, can also be used for refrigerator, air conditioner, electronics, microwave magnetron industry and other stainless steel, carbon steel, brass, copper brazing and bright heat treatment of the parts.
Areas of application: vacuum brazing furnace is mainly used in steel industry, metallurgical industry, etc.

Vacuum fiber welding heat preservation time

Vacuum fiber welding heat preservation time

Time of heat preservation vacuum brazing is done in the condition of vacuum radiation heating. Although the base material thickness is not big, but after considering the loading furnace brazing joint was part of the cover, not directly by radiant heat, work caused by temperature difference, we under heated to solder the liquidus temperature suspends the heating, and under the temperature of heat preservation for a period of time, its aim is to reduce the temperature of the component gradient, make each part temperature homogenization welding and cutting.
Vacuum cooling due to the silver brazing temperature on silver copper alloy solder melting point, and the timely heat preservation, so at this time of silver and copper alloy has melted into liquid, has a certain liquid. Silver copper alloy for plasma arc cutting electrode solder has good electrical conductivity, brazing wettability, and good ability to fill is the numerical control plasma arc cutting electrode ideal solder. Trial, we will first component precooling below the melting point solder, n2 gas filling fast cold again, in order to ensure good between components, thus obtain satisfactory brazing quality.
The numerical control plasma arc cutting electrode after vacuum silver brazing, use in good condition. Import plasma arc cutting electrode using cutting from the plasma arc cutting electrode weld brazing component metallographic image is 300 m, and the use of vacuum silver brazing cutting distance has reached more than 500 m, has been applied in some domestic key enterprises, is gradually replace imports, widespread high praise. From the use of cylinder head bolt, reduced the premature failure of the bolts, such as the bolt fracture or fatigue, etc.). Look from the site conditions to improve the working environment, make originally the lampblack diffuses, ground of the condition of the oil is fundamental improved.
