Cast slab surface temperature measuring device used in continuous casting machine

摘要

A temperature measuring device, which is used in a continuous casting machine, measures the surface temperature of a part or all of a cast slab in a width direction of the cast slab, which is drawn from a mold and conveyed by rollers, in a secondary cooling zone of the continuous casting machine. The temperature measuring device includes a support member that is installed on the side of roller support parts by which the rollers are rotatably supported; an arm member of which a proximal portion is rotatably mounted on the support member; and a radiation thermometer which is provided at a distal end portion of the arm member and of which a light receiving opening is disposed at a position corresponding to a height in the range of 1.0 to 4.5 m from the surface of the cast slab.

1. A cast slab surface temperature measuring device used in a continuous casting machine that measures a surface temperature of a part or all of a cast slab in a width direction of the cast slab, in a secondary cooling zone of the continuous casting machine, the cast slab surface temperature measuring device comprising:
a support member that is installed on a side of roller support parts by which rollers are rotatably supported; an arm member of which a proximal portion is rotatably mounted on the support member, wherein the arm member includes a plurality of short arms which are adjacent to each other and which are foldably connected to each other by a connection part; and a radiation thermometer which is provided at a distal end portion of the arm member and of which a light receiving opening is placeable at a position corresponding to a height in a range of 1.0 to 4.5 m from a surface of the cast slab.
