Abstract
A roll for the support and transport of ingots is disclosed including a core with a helical duct along the periphery covered by a thin sleeve being secured to the groove or duct separating ridges by welding making sure that coolant cannot flow transverse to the duct and that the sleeve cannot slip off the core. A particular welding technique as employed has broader applications including joining plate or sheet stock.
Claims12
A composite body comprising a first metal element having a plurality of ridges delineating a surface plane;
- and
- a second metallic element having a surface situated in said surface plane, further having groove means on the side facing away from said surface plane, bottom portions of the groove means is fused with said ridge means.
A roll for supporting and/or transporting continuously cast objects comprising:
- a core of cylindrical configuration having journal pins at its ends, there being a central duct in each of said journal pins, a shallow trough cut into the surface of the core in several adjoining loops there being relatively narrow ridge means separating the adjoining loops of the trough, there being duct means at the ends of the core interconnecting the trough with the central ducts in said journal pins;
- a single sleeve on top of the core and covering the trough to establish a helical cooling duct of wide cross section, said sleeve being provided with groove means on its outside geometrically matching circumferentially the loops of the trough in radial alignment therewith, leaving looping, narrow bottom means directly adjacent said ridge means and also in radial alignment therewith;
- and
- means for providing a coolant tight and sealed connection between the sleeve and the ridge means for preventing also axial slippage between the sleeve and the core the connection including the entire bottom means fused to the ridge means as well as as weld deposits in the groove means of the sleeve.
A composite body comprising:
- a first metallic element;
- and
- a second metallic element interconnected by welding to the first metallic elment, the second metallic element having a reduced thickness adjacent a surface portion in contact with the first element, the reduced thickness portion fused with the first element.
