The temperature measuring ring is a reliable high-precision product with recognized accuracy and reliability Ceramic temperature measuring rings can be placed almost anywhere in the kiln, inside the furnace body, on push plates or conveyor belts. The working principle of a ceramic temperature measuring ring is to provide the actual accumulated heat of the temperature measuring ring and the fired product based on its linear shrinkage within the working temperature range, and to obtain the test temperature by comparing it with the conversion table. When the ceramic temperature measuring ring is heated in the kiln, it contracts and continues to contract at the highest temperature as the insulation time increases. Within its temperature range of use, the shrinkage rate is linear, providing a practical measurement method for the heating amount received by PRCT ceramic temperature measuring rings and fired products. The shrinkage (decrease in ring diameter) can be measured using a digital micrometer.
The silicon molybdenum bar is somewhat softened at high temperature (above 1500 ℃), and hard and brittle at low temperature. In order to avoid stress during temperature change and facilitate Thermal expansion of components, the free vertical hanging installation method is adopted. The disassembly and replacement of lifting components is also more convenient, and there is no need to wait for the furnace to cool down, but can be heat exchanged. When hanging silicon molybdenum rods, the following precautions must be taken:
Silicon molybdenum bar electric heating element products are widely used in metallurgy, steelmaking, glass, ceramics, refractories, crystals, electronic components, semiconductor materials research, production and manufacturing and other fields, especially for the production of high-performance precision ceramics, high-grade artificial crystals, precision structure metal ceramic, glass fiber, Optical fiber and high-grade alloy steel.
