Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800℃, can be used as heating elements for industrial high-temperature furnaces in electronics, ceramics, magnetic materials, glass, metallurgy, refractory materials, etc. | |
Tongs for crucibles |
| 1Please provide the Chinese content to be translated. | A common chemical instrument, typically used for holding crucibles. Generally made of stainless steel or hard, non-combustible, and oxidation-resistant materials. 2. Use clean tongs. 3. When gripping a hot crucible with tongs, preheat the tip to prevent the crucible from cracking due to localized cooling. After use, place the tip upwards on the desk or a asbestos mat. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying. 5. Use the bent portion for holding crucibles, and the pointed end for other uses. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used alone. | |

Factory environment | 1. Indoor use 2. Environmental temperature is within ±5-45°C range. 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the stove. |
Safety Protection | 1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to dry the furnace to prevent cracking of the furnace chamber. Keep clean regularly and check if the electric furnace wiring is well-contacted. 3. Do not exceed the rated temperature when using the furnace to prevent damage to the heating elements. Prohibit the addition of any flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, when initially heating up, the furnace is cold and requires a significant amount of heat absorption. |
After-Sales Service | 1. We commit to resolving any technical inquiries from our clients within 1 hour. 2. We promise to provide test results within 1 working day for equipment returned for repair, complete the repair within 3 working days, and custom special materials as needed, with appropriate handling. 3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendly Reminder | Do not operate the equipment at the rated temperature for extended periods to ensure its normal service life. 2. Carefully count and verify the quantity of goods and accessories upon receipt to avoid any inconvenience caused by shortages or omissions. 3. To extend the service life of the instrument, we recommend that the warming and cooling rates not exceed 10℃/min. 4. The cooling rate should not exceed 5°C/min. 5. This furnace does not have a vacuum-sealed structure, so flammable and explosive gases cannot be introduced. 6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. Repair can be made by applying an alumina coating. |
