Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with high usage temperatures, are hard and brittle. After molding, they are used, such as silicon carbide rods and tubes, which can reach high heat temperatures under dry air conditions.15001000-1200℃ under vacuum, 1350℃ for long-term use in nitrogen atmosphere |
Silicon Molybdenum Rod |
| 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, forming a dense quartz glass coating on the surface to prevent further oxidation. Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800°C, can be used as heating elements for industrial high-temperature furnaces in electronics, ceramics, magnetic materials, glass, metallurgy, refractory materials, etc. | |
Pot tongs |
| 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 non-oxidizable materials. 2. Use clean tongs. 3. When gripping a hot crucible with tongs, preheat the tip of the tongs to prevent the crucible from cracking due to localized cooling. After use, place the tongs with the tip facing up on the table or a asbestos pad. 4. After the experiment, clean the crucible tongs and place them in the equipment cabinet, allowing them to dry. 5. Use the bent section for holding crucibles; for other uses, employ the pointed tip. 6. Crucible tongs may not necessarily be used with crucibles; they can also be used independently. | |

Factory environment | 1. Indoor use; 2. Environmental temperature within ±5-45°C range. 3. The relative humidity of the surrounding environment does not exceed 85%. 4. No conductive dust, explosive gases, or gases capable of severely damaging metals and insulating materials 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 must be seasoned to prevent cracking in the furnace chamber. Keep clean regularly and check the electrical furnace wiring for good contact. 3. When using the electric furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour any flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the heating rate should be moderate, as the furnace is cold at the beginning and requires a significant amount of heat absorption. |
After-sales service | 1. We commit to resolving any technical inquiries from our clients within one hour. 2. We promise to provide a test result within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials on a case-by-case basis. 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 for extended periods at the rated temperature 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 a heating rate and cooling rate of 10°C/min. 4. The cooling rate should not exceed 5℃/min. 5. This furnace does not have a vacuum-sealed structure, therefore it is not suitable for introducing flammable or explosive gases. 6. After a period of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. It can be repaired using an alumina coating. |
