1. stores reserve
(Need to choose suitable materials)
2.Heating of raw materials
(Place the cut billet into a heating furnace for heating treatment)
3. Rolling of billets
(By gradually reducing the cross-sectional area of the material through a continuous rolling mill, it gradually becomes the outer diameter and length of the bolt)
4.Billet cooling
(The rolled billet needs to be cooled to restore it to room temperature)
5. Thread processing
(Thread machining is an important process in manufacturing hexagonal bolts, generally using turning or rolling machining methods)
The application fields of molybdenum hexagonal bolts are very wide, mainly including petrochemical, power, aerospace, shipbuilding, automobile manufacturing and other fields.
In the petrochemical industry, molybdenum hexagonal bolts are used to manufacture fasteners for pipelines and equipment.
In the field of electricity, molybdenum hexagonal bolts are used for fastening high-voltage transmission lines.
In the aerospace field, molybdenum hexagonal bolts are used as fasteners for aircraft and rockets.
In addition, molybdenum hexagonal bolts are widely used in the fields of shipbuilding and automobile manufacturing, for fastening steel structural components such as bridges and power plant boilers.
The classification of molybdenum bolts includes hexagonal head molybdenum bolts, countersunk head molybdenum bolts, square head molybdenum bolts, slotted molybdenum bolts, T-shaped molybdenum bolts, and special-shaped molybdenum bolts.
The speed and force of rotation should be appropriate, not too fast or too strong. It is recommended to use torque wrenches or socket wrenches, and avoid using adjustable wrenches or electric wrenches to prevent locking due to rapid temperature rise.
The direction of force application should be perpendicular to the axis of the screw for screwing in, and using a washer can effectively prevent the problem of over locking.
