Zero Crown Housing
Sendzimir's Innovative Zero Crown Housing
The Zero Crown Housing is one of Sendzimir’s most innovative and renowned inventions. This unique piece of equipment, designed to allow the mill housing to stretch uniformly under load, has already proven indispensable for numerous customers in their rolling mill projects.
Time-Tested Design
The concept and design of Sendzimir’s Zero Crown housing have stood the test of time. Despite continuous technological advancements and the advent of newer techniques, such as finite element analysis, this original design has consistently proven its worth and validity. While Sendzimir always pursues fresh, innovative solutions, Zero Crown housing continues to set the industry standard with its unbeatable strength and rigidity.
Superior Performance
No other 20-High design can match the strength and rigidity of our Zero Crown Housing, which is recognized globally for its high mill modulus.
How It Works
The Zero Crown housing is designed to stretch uniformly under load, achieved through side frame deflection and transverse slab deflection. This unique mechanism ensures a “zero-crown” contour across the entire strip width. Additionally, the design reduces the amount of material required for the housing while maintaining the strip’s superior shape profile, rendering the Zero Crown housing a comprehensive solution to various rolling mill challenges.
Worldwide Excellence
Our commitment to quality and innovation is reflected in the over 122 Zero Crown Housings built worldwide. All T. Sendzimir, Inc. Licensees also utilize this fundamental design.
Advantages of Zero Crown Housing
Our Zero Crown concept’s Mill Housing operates like a “die,” offering a level of stiffness unparalleled by any other cluster mill design. Benefits include:
- Uniform expansion across the strip width under load
- Significant shape control capability using opposed 1st 1R tapers and As-U-Roll Crown Control (Secondary Backing Assembly eccentrics)
- Most of the mill flexibility is within the mill rolls, not the housing
