Specifications: about 35~40 pieces per box Single size: 6.5*1cm How to use: Take three adjacent "temperature measuring triangular cones" (if you want to know the temperature of No. 10, take No. 9, 10, and 11) and insert them into the refractory mud base side by side, so that the right angle is perpendicular to the bottom surface and inclined 80 degrees , put it into the kiln after drying and place it in the observation place. As the temperature gradually rises, the head of the "temperature measuring triangular cone" bends down, and when the head touches the seat plane, the desired temperature is reached. Precautions for the temperature measuring triangular cone:
1. The softening temperature of the temperature measuring triangular cone will be deviated due to the different heating methods, so the heating must be slow, and it is advisable to increase it by 10 degrees per minute.
2. The refractory clay seat should be laid flat.
3. In order to more accurately grasp the sintering temperature, multiple sets of temperature measuring triangular cones should be selected, and multiple observation points should be set at the same time.
