1. If there are drawings, please send drawings (CAD,PDF, hand sketch), etc.

2. Specify the size, quantity, thickness and other specification.

3. Determine the processing technology (simple cutting, drilling, to map custom parts, grinding, milling saw cutting.

4. Pay according to the actual quotation.

Note: If the size requirements are particularly accurate, please explain to customer service. Because there are certain tolerances in normal process standards such as cutting, grinding and drilling, please explain in advance if there are precision requirements for irregular parts.

Use/Maintenance Methods                                                                                                                                               

The crucible must be kept in a dry and ventilated place, preferably on a wooden carrier. Avoid placing the crucible directly on the brick, soil or cement ground. The crucible will be damaged by moisture, which will reduce the melting efficiency and service life of the crucible. In serious cases, the bottom will even fall off.

The service life of the crucible can be greatly extended by using the correct method of preheating the crucible.

(1) According to different types of crucible furnaces, when the crucible is used for the first time, the crucible should be preheated to about 200 ° C for 60-120 minutes without feeding, and dried for 60 minutes.The purpose is to volatilize the moisture inhaled on the surface of the crucible.Prevent bursting at the beginning of use.

(2) After preheating, the crucible should be heated to 800℃(about 2 hours) as soon as possible, and keep warm for 20~30 minutes, and then rise to or fall to the working temperature.The purpose is to quickly pass through the graphite crucible easy oxidation temperature region.

(3) The crucible usually does not need to be preheated again after this preheating, unless the crucible is damp again.

1. Crucible strength: This test measures the maximum temperature that the crucible can withstand before it cracks or fails.

2. Crucible porosity: This test measures the number of pores or voids in the crucible, which can cause weak points and cause the crucible to fail prematurely. 

3. Crucible thermal shock resistance: This test measures the crucible's ability to withstand sudden changes in temperature without cracking or breaking. 

4. Crucible chemical resistance: This test measures the crucible's ability to resist corrosion from various chemical compounds.

5. Crucible thermal conductivity: This test measures the rate of heat transfer through the crucible. 

6. Crucible thermal expansion: This test measures the amount of expansion or contraction in the crucible when exposed to extreme temperatures.
