Vacuum Technology: Process and Design

Classroom Training


Getting to grips with vacuum process technology in steelmaking can be challenging, so this course helps operational and maintenance staff to master the basics of vacuum pump design, whether based on steam ejectors or dry mechanical pumps.

The course analyzes the metallurgical process requirements of designing a proper vacuum system: gases definition, calculation, safety factors, and process dynamics are the key aspects of determining the pump. Essentially, all aspects of data processing form the foundation for the mechanism of the vacuum pump.

Basic mechanical model definition is the first stage of vacuum pump design. Next comes an economic and benchmarking evaluation, which is also an important component of technical specification preparation. This is followed by “Make or Buy”. Pump installation and start-up are also demonstrated, using examples of previous installations.

The final element of the course is dedicated to the operation and maintenance of the pump, where we delve into all typical aspects of failure analysis and maintenance planning, among others. The course concludes with a look at future and market trends.
