摘要： PURPOSE: To sufficiently cope with local abrasion by providing the device with a first slide support plate provided with wear resistant members supporting the bent sections of a specified angle each at both sides of a belt, and with a second slide support plate provided with smoothing members supporting the outside of a belt width at its bent sections. CONSTITUTION: Impact by material to be carried, which falls down from an upstream side conveyor, is applied to each carrier roller 3. therefore, each carrier roller 3a excellent in stiffness can exhibit its wear resistance against impact by the rotation of each carrier together with the carriage of a belt 3b. The bent sections 3c of the belt 3b are apt to be worn as they slide, since the bent sections are supported by way of wear resistant member 9a composed of ceramics chips, local friction can thereby be prevented. Furthermore, the belt 3b is supported by smoothing members 9b, carrying operations can thereby be sufficiently maintained. Since the degree of abrasion is different between each wear resistant member 9a provided for the first slide support plate 8a and each smoothing member 9b provided for the second slide support plate 8b, they have to be separately replaced, since the slide support plate 8 is provided in a form of both slide support plates 8a and 8b separately, maintanbility can thereby be enhanced.

摘要： PURPOSE:To continuously measure the temperature of molten metal at a molten metal tap hole by hitting and inserting thermocouple type thermometer into the hole with a tapping machine without damage. CONSTITUTION:A protective tube 3 which is made of Mo.ZrO2-based cermet having excellent heat resisting impact resistance, of which surface is spray- coated with a ZrO2 film 4, and in which thermocouples 2 are inserted, is inserted into a metal protective tube 5, and refractory powder 6 made of MgO is filled inside the tube 3 and a gap between the tube 3 and the tube 5. Since the impact resistant strength of the thermometer 1 is improved, the thermometer 1 contained in a thermometer containing chamber 11 of a metal rod 10 can be simply hit and inserted into a tap hole. Even if a metal rod 10 and the tube 5 are eroded, the tube 3 is protected by the coating 4 having excellent heat resistance, and not eroded to protect the thermocouples 2. Accordingly, the temperature of the molten metal can be continuously measured.
