The roll forming method uses a set of continuous frames to roll the stainless steel into a complex shape.
The sheet metal is subjected to a series of continuous rolls to achieve a continuous deformation to obtain a predetermined shape.
The roll forming method uses a set of continuous frames to roll the stainless steel into a complex shape. The order of the rolls is designed such that the roll pattern of each frame continuously deforms the metal until the desired final shape is obtained. If the shape of the part is complicated, up to thirty-six racks can be used, but the simple shape of the parts, three or four racks can be used.
The use of roll forming technology to produce large quantities of long pieces is the most economical. The strip has a width ranging from 2.5 to 1500 mm and a thickness of 0.25 to 3.5 mm. The shape of the machined part ranges from simple to complex, closed sections.
In general, due to the high tool processing cost and installation cost, it is economical to use a roll forming process only when the output is above 30,000 meters. However, the trial production of stainless steel by a roll forming machine using a carbon steel profile is still unclear. In this case, care must be taken to prevent surface contamination or abrasion, and the equipment must be left with stainless steel for cold hardening and a high rebound margin.
