Quartz glass is a special industrial technical glass composed of SiO2 single oxide. It has excellent physical and chemical properties. It is an irreplaceable basic raw material in the development of emerging industries and pillar industries. It is widely used in aerospace, nuclear technology, ast...
Cermet and metal vacuum brazing
Ti(C,N)-based cermet is a typical cermet developed on the basis of TiC-based cermet; it has many advantages, such as high hardness, high melting point, good oxidation resistance, stability to molten metal, resistance to A series of advantages such as cutting. Due to the outstanding advantages of ...
Electric heating element for vacuum heat treatment furnace
With the improvement of the manufacturing level of vacuum heat treatment furnace, vacuum heat treatment gradually shows incomparable advantages. Vacuum heat treatment is favored by people with a series of advantages such as degassing, degreasing, non oxidation and automation. The electric heating...
3Cr13 stainless steel spring vacuum high pressure gas quenching heat treatment
1 Introduction 3Cr13 stainless steel material, because it contains more alloying element chromium, the C isothermal transformation curve of the material is shifted to the right, and the critical cooling rate is small, which makes the material after austenitization can also form martensite in air...
Requirements for deep carburizing on heat treatment equipment
1.Temperature control method The following briefly introduces the difference between the main control method in the furnace and the temperature control method outside the furnace, and the effect of realizing the main control in the furnace on the carburizing quality during deep carburizing. The m...
Common Failure and Maintenance of Vacuum Quenching Furnace
Like ordinary equipment, vacuum quenching furnace will have many failures in the process of use, especially in the case of harsh operating environment and uninterrupted work, the failure rate of equipment is relatively high. If you rely on the equipment manufacturer for repair or transformation, ...
Heat treatment process of gear vacuum carburizing and quenching
Gears are one of the most common and most widely used parts in modern mechanical combinations. There are gears in almost all machinery such as ships, airplanes, automobiles, and cranes, which shows its role and usage. In the process of mechanical use, gear failure occurs from time to time, mainl...
Deformation correction of 20CrMo steel plate by vacuum carburizing and quenching
Steel plate quenching has been a difficult problem in the heat treatment industry for many years. When the surface requires high hardness, leveling is the biggest problem. It is an innovative method to use a cast iron plate to press and quench the parts with small deformation to ensure surface ha...
