ROCHO INDUCTION provides high-strength bolt heat treatment process and bolt induction heating equipment, bolt forging equipment, bolt induction hardening equipment. After bolt heat treatment process, the hardness, wear resistance, strength and service life of the bolt will be greatly improved .
As a common standard part, high-strength bolts have good fastening performance and are usually used in steel structures and engineering to play a fastening role. Generally, in the construction of steel structure workshop, the required steel structure bolts are generally above grade 8.8, which are all high-strength steel structure bolts. Sometimes the bolts on the steel structure do not need to be plated, and it does not matter to use the natural color directly. Generally, high-strength bolts are mostly used for the connection of some bridges, rails and ultra-high pressure equipment. The high-strength bolts used in ultra-high pressure equipment require prestressing to ensure the tightness of the container.
Incandescent heat treatment process
This process generally adopts induction heat treatment or flame heat treatment, and then two hardness testers are used to test the hardness of the screw, and the standard heat treatment method can be selected. The two hardness testers mentioned at this time are: vickers hardness tester and rockwell hardness tester; we can also choose it from the thickness date, when the thickness is thin, use the vickers hardness tester; when the thickness is thicker, use the rockwell hardness tester hardness tester.
Chemical heat treatment process
Double-headed screws can also be chemically heat treated, which is carried out by chemical elements. The screw is put into atoms containing chemical elements to change the chemical composition, structure and function of the screw surface. After chemically treat process, increase the hardness, wear resistance and strength of the stud.
Local treatment process
For stainless steel studs with different requirements, the heat treatment will not be the same part, and not all screws require the entire heat treatment. Only bolts are used for the local heat treatment part, which is a common treatment method, and the type of heat treatment is usually marked with the position and hardness value on the paper.
ROCHO INDUCTION hardening equipment is revolutionizing the bolt heat treatment industry, gradually improving the stability and qualification of high-strength bolts, highly automated, continuously operating equipment that can improve bolt production and consistency, If you are interested in our bolt hardening equipment, please contact us for the latest technical solutions.
