Applications:

1. Graphite crucible cannot be exposed in moisture, and must be placed in indoor dry place or wooden shelf.Maintain ventilated. Moisture is strictly prohibited. Damped crucible is likely to crack.

2. Each crucible, especially damped ones, must be preheated and roasted in drying equipment or next to a ground furnace before use. The roasting temperature should start from a low temperature of 100°C below.Roast it to 150°C at a speed of not higher than 30°C per hour. Preserve the heat for about 8 hours and then dry it. The crucible dried next to a ground furnace should be placed at least for one shift, and often turned to change direction, till workers feel the internal wall of crucible is hot.

3. The melting time for the first time should be at least twice of the normal melting time, in order to avoid cracking inside the crucible due to heating up too fast, or even cracking immediately when the fire sets on.

4. Handle with care. Falling or shaking is strictly forbidden in order to present cracking. Crucible should be placed below the mouth of furnace to prevent the furnace lid abrading the upper edge of the crucible and thus affecting the capacity.

5. Pour out the remaining cold metals inside the crucible after use, and then add new materials. Carefully and gently add new materials into the crucible. Feed materials according to the capacity of crucible. It is not allowed to feed too many materials, in order to prevent crucible from swelling or bursting.

6. Knock gently to remove slags and cokes on the internal and external wall of the crucible. Avoid damaging the crucible body.

7. In the melting process, do not add chloride solvents in order not to corrode the crucible. For the furnace that uses oil and coal gas as fuels, the oil wind should not reach one part of the crucible directly. Turn around the crucible from time to time, in order to avoid local damage.

8. Clamps and other discharging tools should comply with the shape of the crucible. During furnace discharging, remove the cokes on the external wall of the crucible, and lower the furnace temperature; do not discharge at high temperature after stopping blasting. 

Properties:

1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality.

2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.

3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.

4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible.

5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.

6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving.

7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality.
