Causes and Countermeasures of Heat Treatment Cracks in High Chromium Cast Iron
Abstract
This paper mainly introduces the causes and countermeasures of the cracking of high chromium cast iron caused by thermal treatment. High chromium cast iron is a common material used in many areas, so the study of its thermal-treated cracks to provide a theoretical basis for practical wor......

Influence of cooling characteristics and cooling rate of medium on hardenability of steel
The effect of cooling medium characteristics and cooling rate on the hardenability of steel
Hardening of steel, also known as quenching, is an important process used to manufacture products with improved mechanical properties. In the hardening process, heat treatment is performed by heating the s......
heat treatment stress
Heat Treatment Stress
Heat treatment processes involve the application of thermal energy to modify the mechanical and physical properties of materials. By changing the temperature of a material, its internal structure can also be altered, which can result in a desired change in mechanical and phy......
Heat Treatment Deformation Control of Carburized Gears
Overview
Carbo gear heat treatment deformation control is a technique used during the production process of carbo gears, which involves using heat treatment to control the shape and size of the carbo gear. This process is used to maintain the desired shape and size of the carbo gear, and also to ......
Study on Heating Lag Time of Vacuum Heat Treatment
Study of Residence Time During Vacuum Heat Treatment Heating
Heat treatment is an important step in the manufacturing industry. It is used to influence the properties of a product by controlling the temperature history of the material during the process. The temperature reached, the heating rate ......
low temperature rolling
Low Temperature Rolling
Low temperature rolling, which is also known as room temperature rolling, is a metalworking process where the metal is rolled at temperatures lower than the metals recrystallisation temperature. Unlike traditional hot rolling, it does not soften the metal, and no recrystall......

Process Characteristics of Keys and Shafts Parts
Keys and shafts are a type of mechanical components that are used to connect two parts together. They are usually cylindrical or flat and are mainly used for both mechanical and thermal transfer in machines. The two parts are usually made of two ......
Double helix tungsten wire
Twisted Helix Tough Wires
Tough wires are made of alloy steel in a twisted helix construction for mounting to stationary parts. These are primarily used for mechanical and structural applications and have been widely used in industrial, military and commercial applications for decades. It is so w......
The main factor affecting the spread is the amount of depression
Influence of Span Width
Span width refers to the measure of the overall width of a structure, whether it be a bridge, building, highway, or any other type of construction. Span width is a very important factor in determining the structural integrity and stability of a given structure, as the grea......
Eliminate solidification stress and improve billet quality
?
Abstract
Solidification stress is one of the most common problems affecting the quality of castings. If the mold is overcooled, the section changes and the casting is cracked, if it is cooled unevenly, asymmetrical deformation occurs, which causes defects and reduces the quality of the casting. ......
