1. A method for descaling a sheet of metal comprising:
providing a first component for a slurry blasting descaling cell, wherein the first component comprises an enclosure with an interior, the enclosure having a top and a bottom, first and second lateral sides, and front and back sides, the front side having an entrance opening into the interior, the back side having an exit opening into the interior, the front and back sides being transverse to the lateral sides, the enclosure having only one motor driven slurry propelling impeller mounted on the top of the enclosure, the only one motor driven slurry propelling impeller mounted on the top of the enclosure being adapted and configured to propel slurry into the enclosure interior onto a top surface of the sheet metal across an entire width of the sheet metal in a first direction extending from the first lateral side toward the second lateral side when the sheet metal passes through the enclosure interior of the first component, the enclosure having only one motor driven slurry propelling impeller mounted on the bottom of the enclosure, the only one motor driven slurry propelling impeller mounted on the bottom of the enclosure being adapted and configured to propel slurry into the enclosure interior onto a bottom surface of the sheet of metal across the entire width of the sheet of metal in the first direction when the sheet of metal passes through the enclosure interior of the first component;
providing a second component for a slurry blasting descaling cell, wherein the second component comprises an enclosure with an interior, the enclosure having a top and a bottom, first and second lateral sides, and front and back sides, the front side having an entrance opening into the interior, the back side having an exit opening into the interior, the front and back sides being transverse to the lateral sides, the enclosure having only one motor driven slurry propelling impeller mounted on the top of the enclosure, the only one motor driven slurry propelling impeller mounted on the top of the enclosure being adapted and configured to propel slurry into the enclosure interior onto the top surface of the sheet metal across the entire width of the sheet of metal in a second direction extending from the second lateral side toward the first lateral side when the sheet of metal passes through the enclosure interior of the second component, the enclosure of the second component having a single motor driven slurry propelling impeller on the bottom of the enclosure, the only one motor driven slurry propelling impeller mounted on the bottom of the enclosure being adapted and configured to propel slurry onto the bottom surface of the sheet of metal across the entire width of the sheet of metal in the second direction when the sheet of metal passes through the enclosure interior of the second component; and
arranging the first component adjacent the second component to form the slurry blasting descaling cell including arranging the first component relative to the second component such that their respective first lateral sides are aligned on one side of the slurry blasting descaling cell and their respective second lateral sides are aligned on an opposite side of the slurry blasting descaling cell, and such that the sheet of metal to be processed in the descaling cell passes through the entrance opening of the front side of the first component, passes through the interior of the first component, passes through the exit opening of the back side of the first component, passes through the entrance opening of the front side of the second component, passes through the interior of the second component, and passes through the exit opening of the back side of the second component; and further comprising:
providing the first component enclosure with a rinse station, the rinse station being adapted to propel a rinse agent onto the top surface of the sheet of metal across the entire width of the sheet of metal in the first direction when the sheet of metal passes through the enclosure interior of the first component; and
providing the second component enclosure with a rinse station, the rinse station being adapted and configured to propel rinse agent onto the top surface of the sheet of metal across the entire width of the sheet of metal in the second direction when the sheet of metal passes through the enclosure interior of the second component.
