Abstract
A method and apparatus for strapping ingot moulds by forcing roughly pre-formed strap sections into pressure contact around the mark of the mould which is to be strapped, and welding the joints between the sections to form a complete strap. The apparatus includes the frame, with two generally C-shaped portions hinged together to form a bar which can be closed around a mould, the frame carrying hydraulic rams at spaced intervals for pressing the strap sections against the mould.
Claims2
Apparatus for strapping ingot molds comprising a frame surrounding the base of a mold, the frame mounted on rotary means for rolling movement from place to place, and flexibly mounted hydraulic jacks or rams having plungers mounted on the frame for holding two or more non-pliable metal strap sections to the outer surface of said mold and for pressing the sections against said outer surface of said mold to lie around and conform to said outer surface in a pressure fit around said mold, and wherein each said flexibly mounted ram or jack has its end in the frame received in a cup shaped member, said end being convex, and a support plate having a semi-circular cut out located between the said end and the plunger end of said ram, the ram or jack being biased into said cut out by a spring and being further flexibly held in position by symmetrically arranged radial springs.
