Precautions for ashing small samples of Zhengzhou box type resistance furnace (sintering heat treatment)
(1) The samples in the porcelain boat should be spread flat, and the thickness of the samples should not be too large;
(2) When ashing, the furnace door can be opened and the ceramic boat containing the sample on the heat-resistant plate can be gradually pushed into the box shaped high-temperature electric furnace mouth. First, the sample in the ceramic boat is gradually ashed and smoked. After a few minutes, when the sample no longer smokes, the ceramic boat is gradually pushed into the hot part of the high-temperature furnace, and the furnace door is closed to burn the sample at 815 ± 15. If there is a coal sample that ignites or explodes during the ashing process, the coal sample will be invalidated and must be re weighed for ashing.
(3) The furnace should have chimneys or ventilation holes to allow the coal sample to eliminate combustion products and maintain air circulation during the burning process.
(4) The control system of the high-temperature furnace must indicate accurately. The temperature rise capacity of the high-temperature furnace must meet the requirements for determining ash content.
(5) The ashing time should ensure that the sample is ashed at a temperature of 815 ± 15, but arbitrarily extending the ashing time is also disadvantageous.

Zhengzhou Box type Resistance Furnace (Sintering Heat Treatment)Special furnace dimensions can be customized according to customer requirements!
The correct operation process of high-temperature box type resistance furnace
The specific process operation of the box type resistance furnace is as follows:
1. Check the "shift handover record" before starting work.
2. Operators should wear the prescribed protective equipment and be familiar with the "safety operating procedures".
3. Check the lubrication condition of the axle and slide rail of the furnace door opening mechanism.
4. Check the installation and fastening of the furnace lining, resistance wire, and thermocouple lead out rod, and verify if the instruments are functioning properly.
5. Check that the resistance wires at the bottom of the furnace, the bottom plate of the furnace, the transmission mechanism of the movable furnace bottom, and the motor lead wires are in good condition.
6. Check the cleanliness of the furnace and clean the oxide scale.
7. Newly repaired furnaces should be dried according to the "process specifications".
8. Cut off the power and proceed with the baking process according to the "process specifications".
9. Close the door of the box type resistance furnace.
10. Insulate according to the "process regulations".
11. Power on heating.
12. Cut off the power after work.
13. Produce the furnace according to the "process specifications".
14. Reinstall the furnace and repeat the above procedure.
When the box type resistance furnace is operated continuously, the "handover record" must be carefully filled out, and the handover must be clearly handed over to the successor in person.
16. Maintain and upkeep the equipment according to the "Equipment Maintenance Regulations".
