Tempering process of foundry and die steel
Hardenability of Steel
Hardenability is an important characteristic of steel that is used in the manufacture of forging and mold steel components. It is defined as the ability of the steel to obtain a hardness greater than that of untreated steels of the same carbon content when quenched from an ......

No-bake sand mold single production casting weight tolerance grade
Introduction
Investing in products made from castings is something most manufacturers have to consider, with the machining and fabrication of products often taking an exorbitant amount of time and money. Of particular importance in this area of manufacturing is the importance of controlling casti......
Tempering treatment
Heat Treatment
Heat treatment is a process used in materials engineering and metallurgy to change the physical properties of metals and alloys. Treatments include annealing, hardening, stress relieving, normalizing, tempering, and quenching. Heat treatment is used to improve or alter the mechanic......
Heat Treatment of Hardened Steel Plastic Mold
Heat Treatment of Plastic Mould Steels
Steel moulds are the basis of mass production and efficient industrial production. As an important tool material, its performance directly affects the quality of mould products and even affects the success or failure of some industries. The properties of pla......
high temperature tempering
High-temperature Annealing
High-temperature annealing is a metallurgical process that involves heating a material to a temperature above its recrystallization temperature and then cooling it. Annealing is used primarily to improve machinability, stress relief, and/or surface finish on metallic co......
Forging and rolling
Rolling technology is an important process technology in the production of metal materials. In modern industry, it is widely used in steel rolling, aluminum rolling and copper rolling. Rolling technology not only improves the processing performance of metal materials, but also reduces the processi......
Process flow of split rolling
Rolling Process
Rolling is a process of reduction of sheet metal, sheet metal forming and other similar processes to reduce the cross-sectional area of a metal stock. This process is done by passing the metal between two or more sets of rolls, each set performing a particular function in the crea......
Production of double-layer welded steel pipe
Double-layer Welded Steel Pipes Producing
Welded steel pipes are made by rolling a strip of steel and then welding the two edges along the seam. The welded steel pipe has many advantages, such as high strength, good rigidity, and low cost. As the demand for steel pipes increases, the technology o......
