Process parameters of powder roasting in high temperature tube furnace
Temperature
Temperature is one of the most important parameters in powder roasting process. Different materials and applications require different roasting temperatures.The high temperature tube stove has a precise temperature control system,which can realize the precise control of temperature.
Time
Roasting time is also an important factor affecting powder properties.Too short roasting time may lead to incomplete reaction,while too long roasting time may lead to degradation of material properties. Therefore,it is necessary to determine the appropriate roasting time according to the specific material and application.
Atmosphere
The atmosphere during powder roasting also has an important effect on the properties of the material.Common atmospheres include air,inert gases(such as nitrogen,argon,etc.) and reducing gases(such as hydrogen,etc.). The equipment can be equipped with an atmosphere control system to achieve precise control of the atmosphere.
► Powder roasting precautions
Equipment selection:
When selecting a device,it is necessary to select the appropriate equipment model and specification according to the specific application requirements and material characteristics.For example,factors such as furnace size,temperature range,atmosphere control system need to be considered.
Sample preparation:

Safe operation:
In the use of high temperature tube furnace powder roasting,it is necessary to strictly follow the safe operating procedures.For example, protective equipment such as protective glasses and high-temperature gloves need to be worn during operation;During the operation of the equipment,pay close attention to the operating status and temperature changes of the equipment;After the equipment is shut down,it is necessary to wait enough time for the equipment to cool down before disassembling and cleaning.
Quality inspection
► Quality inspection items
Appearance inspection:
Check the surface of the furnace for scratches,rust,deformation and other defects.
Check whether the seal of the furnace door is tight and whether there is air leakage.
Observe whether the furnace tube and connecting parts are intact,loose or broken.
Temperature uniformity test:
A thermocouple or other temperature sensor is used to uniformly arrange multiple measurement points in the furnace.
At the set temperature,the temperature data of each measuring point is recorded,and the temperature uniformity deviation is calculated.
Evaluate the uniformity of the temperature distribution in the furnace to ensure that the material is heated evenly during the roasting process.
System accuracy test:
Verify the accuracy of temperature control system and display system.
Calibrate the temperature sensor in the furnace using a standard thermometer or thermocouple.
Verify that the control system can accurately respond to and maintain the set temperature.
