Silicon Molybdenum Rod |
| 2Please provide the Chinese content to be translated. | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface to protect them from 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 local cooling. After use, place the tongs tip up on the table or a fiber glass mat. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent portion for holding crucibles; use the pointed end for other purposes. 6. Crucible tongs are not necessarily used with crucibles; they can also be used independently. | |

Special Note
Quality Warranty | One-year full machine warranty, excluding related consumables (mat boards and heating elements excluded)Lifetime On-Site Maintenance |
Factory environment | 1. Indoor use 2. Environmental temperature: ±5 to 45℃ range 3. The relative humidity of the surrounding environment should 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 initially using or reusing an electric furnace after a long period of disuse, it is necessary to perform a baking process to prevent cracking of the furnace chamber. 2. Keep clean regularly and check the electrical furnace wiring for good contact periodically. 3. During operation, the furnace temperature must not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour flammable liquids or melted metals into the furnace. 4. During the process, the temperature should generally not exceed 300°C, and the heating rate should be moderate. This is because when the furnace starts to heat up, it 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 customers within one hour. 2. We promise to issue the test results 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 of returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultations. |
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 that the heating and cooling rates not exceed 10℃/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, this furnace may develop minor cracks in the furnace chamber, which is a normal occurrence and will not affect its operation. These can be repaired using an alumina coating. |
