Abstract
The Vertical Scale Breakers have a very great improvement which compared to the pasting in recent years. They use more and more extensive in production of rolling steeling. They are more essential rolling steel equipment in such aspects as broken scale, controlled    the width of the panel base in hot-rolled sheet metal and belted steel production, and so on. The new-typly Vertical Scale Breakers receive a lot of favor in our country’s Iron and Steel Companies, and have produced the remarkable economic benefits.
The main purpose to design this time are having a further understanding to the whole structure of the Vertical Scale Breakers’ equipment, then checking and calculation to the main parts. While consulting a large number of documents and understanding relevant knowledge, the directed teacher leads us to visit the An Shan’s Iron and Steel Company. Through the practice of one month, the understanding to the Vertical Scale Breaker has a great improvement which rising to perceptual knowledge from rational knowledge too.

Designing includes the development of the wide belted steel of the hot-rolled in domestic and overseas this time, the development of the Vertical Scale Breaker, the introductions of the Vertical Scale Breaker, designing of the Vertical Scale Breaker’s main driving system, the checking and calculating of the main power parameter, and so on. It all makes form of the driving to the Vertical Scale Breaker which is underneath the ground in most Iron and Steel Companies, and the main characteristic designed this time is that the Vertical Scale Breaker’s driving form that will above the ground.
