Precautions For Heat Commissioning And Heating Of Vacuum Heat Treatment Furnace
The characteristics of the vacuum heat treatment furnace with strict vacuum sealing, most heating and insulation material can only be used in the vacuum state, water cooling device, vacuum heat treatment furnace, furnace shell, furnace cover, electric heating element guide don’t treat (wate...
How to Detect the Thickness of Sintering Furnace Lining
How to detect the thickness of the sintering furnace lining is a relatively important part. The quality and thickness of the sintering furnace have a relatively large impact on the use of the electric furnace. Furnace lining refers to the furnace wall of the furnace used for refining metal, which...
Operation Steps of High Temperature Brazing Furnace
How to operate the high temperature brazing furnace more convenient? How to do daily maintenance work during use? The operator of high temperature brazing furnace should understand various appearances, pumps, and various parts of brazing furnace equipment. Read and understand various manuals. Th...
Characteristics and Classification of Brazing Furnace
1. Features The brazing furnace has precise and reasonable heating furnace partitions, high-precision advanced temperature control instrument hardware selection and software parameter adjustment, the furnace temperature control accuracy is extremely high (±1℃), and the temperature uniformity of t...
What is the Structure and Working Principle of the Air Cooling Island of the Brazing Furnace?
The brazing of the air-cooled island radiator brazing in the brazing furnace uses air as a cooling medium to cool the generator stator and rotor windings and the stator core.\ The so-called “air-cooling island” is actually an image term for the air cooling device of a power plant, whi...
Vacuum Repair Welding Process
1. Cleaning the workpiece to be repaired. For casting cracks, welding cracks or quenching cracks of new parts, the surface is usually polished with a fine emery cloth and then cleaned with alcohol or acetone. For iron and cobalt-based superalloy cracks, generally, only surface degreasing, sandbl...
Vacuum Brazing Process For High-pressure Turbine Blades
The high-pressure one-stage turbine blades for aero-engines are made of nickel-based casting alloys K38G and CH3030. It is required to braze a cover plate to restrict the cooling air flow on the blade crown. The brazing filler metal is BNi79CrSiBCo adhesive tape brazing filler metal with a thick...
What is Heat Treatment?
1. Quenching The main purpose of the quenching treatment is to rapidly cool the steel material in order to obtain a very hard Asada bulk structure. There are three essential elements for the quenching treatment of steel, one of which is indispensable. They are: heating in the austenitic area for ...
Heat Treatment Stress And Influence
Heat treatment residual force refers to the residual stress of the workpiece after heat treatment, which has an extremely important influence on the shape, size and performance of the workpiece. When it exceeds the yield strength of the material, it will cause deformation of the workpiece, and wh...
Tempering Transformation and Structure of Quenched Steel
When the quenched carbon steel is tempered, with the increase of the tempering temperature and the extension of the tempering time, the following transformations will occur accordingly. 1. Segregation of carbon in martensite When tempering at a very low temperature below 80°C, it is difficult fo...
