Method for Casting Metal Strip with Edge Control
9 Dec 20
This disclosure concerns methods and apparatus for continuously casting thin strip where one or more expansion rings are positioned within at least one of a pair of casting rolls, and automatically measuring a thickness of the cast strip close to the first side edge of the strip using at least one sensor, and if the thickness measured is too thin, automatically decreasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to contract and increase the thickness of the cast strip during casting, and if the thickness measured indicates that the thickness of the cast strip is too thick, automatically increasing the radial dimension of the expansion ring arranged in close proximity to the first side edge to cause the cylindrical tube to expand and reduce the thickness of the cast strip during casting.

Utility
Apparatus for Making Thin Floor Plate and a Thin Floor Plate
25 Dec 19
A method of making floor plate includes assembling a pair of casting rolls laterally disposed to form a nip, assembling a hot rolling mill downstream of the nip having work rolls with a surface pattern forming the negative of a raised slip-resistant pattern desired in a floor plate, introducing molten metal through at least one metal delivery nozzle to form a casting pool supported on the casting rolls above the nip; counter rotating the casting rolls to form shells on the casting surfaces of the casting rolls to cast metal strip of less than 2.2 mm thickness downwardly from the nip, and delivering the cast metal strip to and through the hot rolling mill to form by the negative of the slip-resistant pattern on the work rolls a raised slip-resistant pattern of between 0.3 and 0.7 mm in height in a floor plate of less than 1.7 mm thickness.
