The working vacuum should be selected according to the material and heating temperature. First, the working vacuum required for no oxidation heating should be met, and then the surface brightness, degassing and evaporation of alloy elements should be comprehensively considered. The working vacuum of commonly used materials is recommended as follows:真空热处理 Vacuum heat treatment推荐工作真空度Recommended working vacuum真空钎焊 Vacuum brazing推荐工作真空度 Recommended working vacuum钢（合金工具钢、结构钢、轴承钢） &n…
Vacuum furnace furnace size can be according to the heat treatment single product size, shape and a furnace capacity. Vacuum furnace is divided into horizontal (single chamber, double chamber, multiple chamber structure) and vertical vacuum furnace (slender parts suspension or plate parts heat treatment), limited by the structure and cost of horizontal single chamber structure is the most commonly used vacuum heat treatment furnace, vertical vacuum furnace due to the layout has lifting transmission system, procurement cost slightly higher, our commonly used horizontal vacuum furnace effective …
Vacuum furnace shell is the working space from the sealed container, is also the basis of the furnace parts installation, furnace shell for double wall water cooling compression container, should have enough mechanical strength and stability, prevent force and heat after deformation and damage. According to the shell material is divided into all carbon steel material, and inner wall stainless steel material but other for carbon steel material.

The equipment can choose different heating elements and heat insulation layers according to different operating temperatures. The commonly used heating element materials are heat-resistant steel(Cr20Ni80), high-purity graphite, molybdenum and alloys,etc.The temperature range is as follows. In addition to the selection of the above materials, it is necessary to comprehensively consider the energy consumption and stability under long-term use.工作温度 Operation Temperature加热元件选择 &nbs…
Heat treatment is an important basic process to improve the performance, reliability and service life of mechanical parts. Heat treatment can maximize the excavation and play the potential of metal materials, so that mechanical parts can fully meet the performance requirements and service life under various service conditions. The advantages of vacuum heat treatment are no oxidation, no decarbonization, no pollution; clean surface, small distortion; excellent comprehensive mechanical properties; wide application; high automation; high production efficiency; stable product quality and energy sa…
