Abstract:
The invention relates to a device for raising and withdrawing a bearing unit (3) of a back-up roll (1) of a roll stand. Said bearing unit is comprised of a piece (4) to be inserted inside which has a roll pin bearing arranged therein. According to the invention, a change-over device (16) is configured so that it can be temporarily coupled to the bearing unit (3) and is provided for effecting an axial movement toward and away from the back-up roll (1).
Abstract:
A monolithic, multi-layer heating element (26, 126, 226) forms the high temperature tip (22, 122, 222) of a glow plug assembly (20). The heating element (26, 126, 226) includes a conductive core (48, 148, 248) which is surrounded by an insulator layer (50, 150, 250), which in turn supports a resistive layer (52, 152, 252). An optional conductive jacket (172) can surround the resistive layer (152). These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die (54, 64, 164), where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element (26, 126, 256). The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass. Various finishing operations may be required, following which the heating element (26, 126, 226) is assembled to form a glow plug (20).
