Furnace tensen
The strip passes through the furnace under controlled tension, intended to utilize the self-guidance of the steering roll. And avoid the deformation of the ladle due to excessive middle force (mainly in the heating section). The tension of each section is controlled separately by two tension measuring units at the inlet or outlet roller bearing bearing. The correction of the steel belt in the furnace is mainly realized by the komprehensif ifek blong rola taep mo tensen.
