Process and apparatus for pickling metal strips |
摘要 |
A method of pickling a material strip is provided that prevents spots from forming and removing formed spots on a material strip that comes to a standstill during the pickling process. The material strip is passed in a first direction through at least one pickling section to form a first pickled material strip. The first pickled material strip is passed in the first direction through at least one rinsing section to form a first rinsed material strip. The first rinsed material strip is sensed when it comes to a standstill. Pickling solution is applied to at least a portion of the first rinsed material strip when the first rinsed material strip has come to a standstill to form a second pickled material strip. The second pickled material strip may then be moved in a second direction that is opposite to the first direction to move the material strip back into the pickling section to form a third pickled material strip. The direction of travel is then reversed back to the first direction to pass the third pickled material strip through the rinsing section to form a second rinsed material strip, which is then passed through at least one first pair of squeeze rollers to remove rinsing solution.
