Q960C/Q960D/Q960E steel plates are quenched and tempered high-strength plates. Due to the large yield force of the high-strength steel of the Q960 steel plate, more energy is required to yield the Q960C/Q960D/Q960E steel plate than the general plate. In addition to deformation, this energy is largely due to pushing (friction) between the plate and the mold.
Therefore, as the deformation temperature of the metal in the stamping die will continue to rise, the oil-based lubricating oil will become thinner, and in some cases it will reach the flash point or burn (smoke), and the lubrication will fail. However, IRMCO high molecular polymer extreme temperature lubricant contains anti-extreme pressure substances and has "heat-seeking" properties and will stick to the metal. As the temperature rises, a tough protective barrier is formed on the surface of the mold and the plate, thereby reducing Friction and temperature to help the workpiece to extend better, so as to control friction and metal flow; at the same time, protect the metal from overheating, blackening, cracking and bonding.
Q960C/D/E quenched and tempered steel size, shape, weight and tolerance:
The size, shape, weight and allowable deviation of Q960C/D/E quenched and tempered steel shall comply with the provisions of GB/T 709.
Q960C/D/E steel plate production process:
Production process: primary refining→LF refining→VD treatment→continuous casting (die casting)→cleaning, heating→rolling→(stacking)→surface inspection→batching→flaw detection→heat treatment→cutting and sampling→performance inspection→warehousing.
Cutting process
Q960C/Q960D/Q960E steel plate factory inspection after the performance indicators meet the requirements, according to the cutting process, can be cut processing and drawing blanking, generally when the thickness of the steel plate is not greater than 20mm, the CNC plasma cutting or CNC laser cutting method is preferred, if the steel plate If the thickness is greater than 30mm, CNC flame cutting is usually selected, which can control the cutting accuracy and time.
