ABSTRACT:
In a hot top mounting method for mounting hot top insulation boards to the inside upper surface of a metal ingot mold, a plurality of spaced parallel metal straps are first affixed to a surface of each board, and each board is then fastened to the mold inner wall by setting a plurality of headed fasteners through the strap and into the mold wall using an air operated, magazine-type fastener driving tool. The straps are preferably of channel cross-section which then act as guides to locate the tool for the fastening operation. The channel straps when disposed vertically can have a row of spaced apertures in one edge which selectively receive a U-shaped hanger for suspending the board from the mold top edge for the fastening operation, the hanger being removed once fastening is complete. The straps can be disposed in other orientations such as horizontal depending upon the fastening pattern required. The tool is provided with an elongated handle to permit it to be used down in the mold from above the mold.
