The present work involves Static and dynamic loads on the foundation of modular frames of compact rolling for cold rolling mill (CCM). Basically there are three types of loads acting on the mill foundation. The loads are static loads, dynamic loads, and maximum load. Static load refers weight of the equipment. Dynamic load comes in to the picture

WhatsApp: +86 18838072829The design of a machine foundation is more complex than of a foundation which supports only static loads. If a machine is rigidly bolted to the floor, the vibratory movement of the machine itself may be reduced, but the vibration transmitted to the floor will be large. This may produce harmful effects even at large distances.
