In the glass manufacturing industry, precise temperature control runs through the entire production process. From the melting of glass raw materials to forming, annealing and other stages, slight temperature differences may have a significant impact on the quality of glass. Dry-block calibrators play a crucial role in temperature process calibration of glass manufacturing. It can be used to calibrate temperature sensors in glass melting furnaces to ensure that during the high-temperature melting stage, the raw materials can be heated evenly and reach the ideal melting temperature, so that the glass liquid has good fluidity and uniformity, which is essential for the production of high-quality, flawless glass products. In the glass forming process, such as blowing and pressing, dry-block calibrators can calibrate temperature sensors of molds to ensure that the mold temperature is appropriate, so that the glass can be accurately formed and reduce deformation and stress defects. In addition, in the annealing process, dry-block calibrators can calibrate the temperature monitoring system of annealing furnaces, allowing glass products to eliminate internal stress during the slow cooling process, improving the strength and stability of glass and meeting the strict quality requirements of different application scenarios.
