Silicon carbide material mechanical seal

The mechanical seal is an axial end face sealing device that relies on the elastic element to pre-tighten the sealing pair, and presses the sealing pair under the combined action of the medium and the elastic element to achieve sealing. Its structure is shown in the figure. There are two kinds of...

Vacuum heat treatment of 0Cr17Ni4Cu4Nb stainless steel base

0Crl7Ni4Cu4Nb steel is a typical precipitation hardening martensitic stainless steel with high strength, corrosion resistance, oxidation resistance, excellent formability and weldability, etc. It is widely used in aerospace, petroleum, chemical, nuclear industry, energy, etc. In the industrial fi...

Vacuum low pressure carburizing heat treatment for heavy duty gears

Heavy-duty gears are generally subjected to large torques during use. In order to ensure efficient and stable transmission of power when the parts are in service for a long time, they have high requirements for their fatigue performance. Such parts generally use carburizing and quenching methods ...

Main points of stainless steel EGR brazing process

1. Brazing joint connection method: Brazed joints are available in two ways: butt joint and lap joint. Butt joints are used, because the strength of the brazing filler metal and the brazing seam is generally lower than that of the base metal, so the butt joint cannot guarantee that the joint has...

Magnetic Materials Vacuum Heat Treatment Process

The raw materials of soft magnetic alloys are mainly rods, strips and plates, etc. The parts are cut, punched, punched or rolled by cold working. During the processing, the original grain structure of the material will be destroyed, which will reduce the magnetic permeability of the material. At ...

Vacuum Brazing Technology of Tube-and-Strip Heat Exchanger and Factors Affecting Brazing Quality

The vacuum needle brazing process is one of the key technologies in the manufacture of automotive air-conditioning tube-and-belt heat exchangers. Only by strictly controlling various factors affecting the quality of vacuum brazing can we ensure stable product quality. The commonly used materials ...

Application of Reaction Sintered SiC-B4C Ceramic Materials

Reaction sintered silicon carbide (RBSiC) is a process in which liquid silicon infiltrates into a carbon-containing body at high temperature, and reacts with carbon to form silicon carbide, so that the body can be sintered. The preparation of silicon carbide by the reaction sintering process inhe...

Vacuum brazing of locomotive aluminum exchanger

With the development of economy, my country has increased the speed of train transportation five times in a row, so the requirements for the heat exchanger of locomotives are getting higher and higher. The traditional locomotive heat exchanger is made of copper alloy. Since the density of aluminu...

Carburizing Process Introduction

Carburizing refers to the process of infiltrating carbon atoms into the surface layer of steel. It is also to make the work-piece of low carbon steel have the surface layer of high carbon steel, and then through quenching and low temperature tempering, so that the surface layer of the work-piece ...

Heat Treatment of Buick Automatic Transmission Parts on Low Pressure Vacuum Carburizing Furnace

Due to the material selection and shape design of some parts of Buick sedan 4T65E transmission, the heat treatment deformation is difficult to control, and the most typical ones are thin-walled parts such as the final deceleration sun gear shaft. The part is made of SAE 4130 annealed welded seaml...
