Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with higher operating temperatures, are hard and brittle. After molding, they are used in applications such as silicon carbide rods and tubes, which can reach high heat temperatures under air-dry conditions.1500100-120°C, for use under vacuum conditions; long-term use temperature of 1350°C under nitrogen atmosphere |
Silicon Molybdenum Rod |
| 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, forming a dense quartz glass film 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. | |
Tongs for crucibles |
| 1Leave it as is. | 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 desk or a asbestos mat. 4. After the experiment, clean the crucible tongs and place them in the lab equipment cabinet for drying storage. 5. Use the bent section 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 independently. | |

Special Note
Quality Assurance | One-year full machine warranty, excluding related consumables (excluding pads and heating elements); lifetime on-site repair service. |
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 insulate corrosive gases around the stove. |
Safety Protection | 1. When an electric furnace is first used or after a long-term shutdown and is reused, it must be seasoned; otherwise, it's prone to cracking in the furnace chamber. Keep the area clean and regularly inspect the electric furnace wiring for secure contact. 3. When using the furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is forbidden to pour various flammable liquids and 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 heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |
After-sales Service | 1. We commit to resolving any technical inquiries from our clients within 1 hour. 2. We promise to issue the test results for equipment returned for repair within 1 working day, 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 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 under-shipping or missing items. 3. To extend the service life of the instrument, we recommend a heating rate and cooling rate of 10℃/min. 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 operation. These can be repaired using an alumina coating. |
