由于轧制压力日益增加,现代轧机的牌坊承受的负载也越来越大。若考虑屈服强度方面的破坏因素,轧机牌坊危险断面上产生的应力是特别低的。在大多数情况下,轧机牌坊是根据为防止牌坊挠曲所需的刚性来设计的,以便能更精确地控制轧材的厚度。 Due to the increasing rolling pressure, the load on the modern mill’s archway is also growing. The stress generated on the dangerous section of the mill arch is exceptionally low when considering the destructive factors in yield strength. In most cases, the mill arch is designed with the rigidity necessary to prevent flexing of the arch in order to be able to control the thickness of the material more precisely.
