Material classification of high-temperature alloys
1. Classification by matrix element type: Iron-based high-temperature alloy: The matrix is iron, with a small amount of alloy elements such as nickel and chromium added. This type of alloy is also called heat-resistant alloy steel, which can be divided into martensite, austenite, pearlite, ferr...Read more -
High-frequency quenching
High-frequency quenching is mostly used for surface quenching of industrial metal parts. It is a metal heat treatment method that generates a certain induction current on the surface of the workpiece, quickly heats the surface of the part, and then quickly quenches it. Induction heating equipment...Read more -
Worm gear
Worm gear mechanisms are often used to transmit motion and power between two staggered axes. The worm wheel and worm are equivalent to the gear and rack in their middle plane, and the worm is similar in shape to the screw. Many worm gears have an interesting feature that other gear sets do not ha...Read more -
Spline sleeves
Spline sleeves Spline sleeves are a kind of mechanical parts, which are widely used in various mechanical equipment to connect and transmit power. The design of spline sleeves makes the connection between shaft and hub more firm, and can withstand large loads and torques. It is particularly suita...Read more -
The welding process
The welding process is related to factors such as welding methods. The operation should be determined according to the material, brand, chemical composition, weldment structure type, and welding performance requirements of the welded workpiece. Try to open the weldment into a U-shaped groove for ...Read more -
Worm gear processing
Worm gear processing Worm gear processing, worm gear is a gear with special tooth shape that meshes with the worm. The cutting of worm gear teeth is generally completed by hobbing machine, mainly hobbing and flying cutter cutting. Worm transmission is used to transmit motion and torque between tw...Read more -
Analysis of the advantages and disadvantages of sand casting
Sand casting has many advantages: 1. Wide selection of materials. Sand casting can complete the casting of many metal raw materials, such as steel, iron and most non-ferrous alloy materials. As long as it is a metal that can be melted, it can be easily completed using sand casting; 2. Design flex...Read more -
Heat treatment applications-1
Heat treatment refers to a metal hot processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and properties. 1. Normalizing: A heat treatment process in which steel or steel parts are heated to an appropriate temperature above t...Read more -
