Silicon Molybdenum Rod | | 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface, protecting them from further oxidation. Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, temperatures 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-flammable, 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 upwards on the desk or on a asbestos mat. 4. After the experiment, clean the crucible tongs thoroughly and place them in the equipment cabinet for drying storage. 5. Use the bent portion for holding crucibles; for other uses, employ the pointed end. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Special Note
Quality Assurance | One-year warranty on the entire machine, excluding related consumables (mat boards and heating elements excluded).Lifetime On-Site Maintenance |
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 furnace. |
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 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 strictly prohibited to pour various flammable liquids and melted metals into the furnace. 4. During the working 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 | We promise to address our customers' technical inquiries within one hour. 2. We promise to issue 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 of returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendship 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 heating 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; therefore, it is not suitable for introducing flammable or explosive gases. 6. After some time of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. These can be repaired using an alumina coating. |
