High-Temperature Furnace Thermocouple Calibration Block

1. The main basis for the ceramic firing process is temperature management. However, in practice, the fired products may vary depending on the furnace specifications, methods, heat capacity, etc.
2. Japanese precision temperature-indicating pellets are practical reference materials manufactured through strict management of raw material composition, particle size, molding density, etc., and can provide more accurate temperature control.
3. The temperature-indicating pellets are fired together with the products to be fired. After firing, the firing conditions can be managed by measuring their dimensions.

Features

• Can be used as an evaluation tool for standardizing firing conditions and integrating technical data.
• Regular and continuous use allows application in abnormal management of firing furnaces and statistical quality control management, etc.

Applications
Firing management and statistical quality control management of fine ceramics, electronic ceramic materials, ceramic products, etc.

Usage Method

Place the temperature-indicating pellet in the furnace and fire it together with the product. After firing, take it out once it cools down to room temperature, and measure its dimensions with a caliper.

Please note: Keep it at room temperature for more than 1 hour.

Management Method

Compare the measured dimensions with the table below, and use the indicated temperature as the management index. The indicated temperature is not the actual physical temperature, but a comprehensive heat-receiving index that integrates the conditions of the fired product. This indicated temperature corresponds to the set temperature under firing conditions of a heating rate of 200℃/hour, a holding time of 2 hours, and a cooling rate of 300℃/hour.

Precautions for Use

If this product is used in a vacuum furnace or a furnace with low oxygen concentration, some components may evaporate, which could contaminate the high-temperature electric furnace. Users must pay full attention to this.
