Diagnosis Test of 150℃ Low Temperature Tempering Capability of Open Flame Normalization Furnace
The low temperature tempering capability of open flame normalization furnace is tested by the temperature testing equipment. The temperature testing should be conducted while the furnace is at a given temperature; 250°c is the most commonly used temperature when testing. The process is conducted to ensure the furnace can reach and maintain low temperatures, no matter what size, shape, or weight the workpiece is.
For this particular test, the temperature testing equipment measures the workpiece’s temperature when it is 150°c. The results allow for a determination of the quality of the tempering process at that given low temperature. The primary goal of the test is to ensure the furnace can properly temper the workpiece in a controlled, uniform manner without any risk of fracture or internal defects.
The test requires all the necessary safety precautions, as any large temperature changes can cause extreme heat radiation or contact. The furnace must also have proper insulation, with good air circulation and ventilation to prevent workpiece warping or time-dependent thermal stresses.
In addition to the basic safety precautions, the open flame normalization furnace must be sized to accommodate the workpiece. A higher size will permit more uniform heating and cooling, which is essential for the outcome of the tempering process. If the furnace is too small, it can create an uneven heating/cooling effect, leading to inaccurate temperature readings and undesired results.
The test itself is conducted in three steps. First, the temperature testing equipment is connected to the workpiece, and the workpiece is then placed in the furnace. Once the furnace is turned on, the equipment will measure the temperature of the workpiece as it steadily increases. Once the desired temperature of 150°c is attained, the equipment must hold the workpiece at that temperature for a set amount of time, usually around 30 minutes, before proceeding to the next step.
Second, the furnace is then cooled at a controlled, steady rate. This allows the equipment to measure the temperature decrease and track any potential temperature fluctuations. Finally, once the temperature drops to the desired level, the workpiece is removed from the furnace and inspected for any defects or deformations.
Overall, the low temperature tempering capability of open flame normalization furnace is an important quality control test. It ensures the furnace can properly temper the workpiece in a uniform, controlled manner without risk of fracture or internal defects. By following the proper safety procedures and proper equipment sizing, this process can provide accurate results and reliable tempering for any workpiece.
