Composition and structure of vacuum hardening furnace
Structure of vacuum hardening furnace (furnace body) The horizontal single-chamber air-cooled vacuum hardening furnace is mainly composed of the following parts: furnace shell, heating chamber, heater, furnace bed, etc. (1)Furnace shell. The furnace shell includes the furnace body, furnace door,...
Why choose vacuum brazing for stainless steel heat ex-changer
Stainless steel has the characteristics of high corrosion resistance, high strength, good heat resistance and good hygiene, so stainless steel heat ex-changers are widely used in chemical, food, pharmaceutical, petroleum, marine and other industrial fields. The traditional brazing process requir...
Vacuum hardening process and vacuum furnace system composition
Vacuum hardening process The typical process of vacuum hardening can be divided into three stages: exhaust stage, heating stage, and cooling stage. (1) Exhaust stage. After the workpiece is loaded into the furnace, the furnace chamber is first exhausted to create a vacuum environment to prevent t...
Main types of vacuum quenching furnace equipment
Vacuum quenching furnace is the main type of vacuum heat treatment furnace, with many varieties, large quantity, complex structure and rapid development. Classification method of vacuum quenching furnace There are many classification methods for vacuum quenching furnace, which can be roughly divi...
Vacuum Nitriding Heat Treatment-Increase Part Performance
Issues to be noted in vacuum nitriding (1) Vacuum nitriding is the last process. After vacuum nitriding, the workpiece can only be finely ground or grinded at most, and no other processing is required. This is because the nitriding layer is relatively thin, generally 0.3~0.5mm. If it is machined ...
What is the process of vacuum nitriding?
Vacuum nitriding process Different from gas nitriding, vacuum nitriding does not use the one-stage, two-stage, and three-stage nitriding methods of traditional gas nitriding, but uses pulse nitriding for nitriding. Vacuum treatment has the effects of less oxidation, degassing and degreasing, but ...
Introducing vacuum nitriding and vacuum carburizing processes
Vacuum nitriding furnace Nitriding treatment refers to a chemical heat treatment process that infiltrates active nitrogen atoms into the steel surface to form a nitride hardened layer under the premise that the critical point Ac1 of steel is lower than that of steel and the matrix does not under...
Four advantages of copper vacuum annealing process
What are the advantages of vacuum annealing of pure copper? (1) Effectively prevent hydrogen embrittlement Vacuum annealing of copper can effectively prevent hydrogen embrittlement. Oxygen-containing copper will become brittle and crack when heated or used in a reducing atmosphere (H, CO, CH). Th...
Detailed Guide to Vacuum Annealing of Steel Materials
Advantages of Vacuum Annealing of Steel Materials Although vacuum annealing of tool steel and ordinary structural steel accounts for a small proportion of the total annealing, it is increasing day by day. Its main purpose is to obtain a bright surface. Vacuum annealing between the processes of th...
Do you know the advantages of vacuum annealing of soft magnetic materials?
Introduction to vacuum annealing process of soft magnetic materials Magnetic materials are widely used in power transmission and transformation equipment, communications, electronic computers, household appliances, automobiles, aerospace and other industrial fields to make electrical and electron...
