Abstract
A filter for use in a coupling disposed between first and second tubes which convey lime from a movable carrier to a processing pot in a steel mill. The filter has a plurality of openings sized and positioned to allow passage of lime and exclude contaminants of a size larger than the size of the perimeter of selected openings reduces erosion by the lime.
Claims7
A method for transporting dry lime from a movable carrier to a processing pot in a steel mill and preventing contaminants that could damage components of the steel mill from being transported with the lime, said method comprising:
- transporting dry lime from the movable carrier through a tubing in which a filter is positioned to exclude the contaminants commonly present in lime, said filter comprising a plurality of openings sized and positioned to allow passage of the lime and to exclude contaminants of a size larger than the size of the opening;
- wherein said filter is reinforced at least on a portion of the perimeter of selected openings of said plurality of openings, said reinforcements comprised of material resistant to corrosion by lime;
- and
- transporting the filtered dry lime to the processing pot in a steel mill.
A transport which conveys dry lime from a movable carrier to a processing pot in a steel mill by means of pressurized gas, said transport comprising a first tubing connecting on a first end to a fitting on the movable carrier and on a second end to a first end of a coupling apparatus, and wherein a second end of the coupling apparatus is joined to a second tubing leading to a holding tank, and wherein a filter is positioned within said coupling apparatus, said filter comprising:
- a plurality of openings sized and positioned to allow passage of lime and exclude contaminants of a size characteristic of contaminants commonly found in dry lime, said size larger than the size of the opening;
- and a reinforcement to at least a portion of a perimeter of selected openings of said plurality of openings, said reinforcement being comprised of material resistant to corrosion by lime;
- and wherein contaminants commonly found in lime comprise sizes characteristic of bricks, rocks, bottles and disposable dishes.
