The Application of Jumping Roller in Tension Control Before An-nealing Furnace
When the stainless steel horizontal continuous annealing furnace production line is subjected to high-temperature annealing in the furnace,small tension control measures must be taken to avoid excessive tension causing narrow deformation of the strip steel in a high-temperature environment,in order to meet the requirement that the thickness of the strip steel is less than 0.2 mm.At present,the tension control mode in front of the furnace is direct tension control mode,which causes signifi-cant fluctuations in the tension inside the furnace under small tension settings,leading to the occurrence of rib and ship shaped defects in the high temperature section of the strip steel.To eliminate production defects caused by tension fluctuations,the method of adding a jumping roller in front of the furnace is adopted.The indirect tension control method of the jumping roller is used to control the position of the jumping roller,thereby reducing the tension and fluctuation of the strip steel in the furnace,and eliminating the quality defects mentioned above during the high-temperature annealing of the strip steel.
