Silicon Molybdenum Rod |
| 2Please provide the Chinese content you would like translated into American English. | 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. Thus, 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 sectors such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
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 non-oxidizable materials. 2. Use clean crucible 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 upwards on the table or asbestos pad. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying. 5. Use the bent section for holding crucibles; use the pointed end for other applications. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used separately. | |

Special Note
Quality Assurance | One-year warranty on the entire unit, excluding related consumables (excluding pads and heating elements)Lifetime On-Site Maintenance |
Factory Environment | 1. Indoor use 2. Environmental temperature is within ±5-45°C range. 3. The relative humidity of the surrounding environment shall not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulate corrosion are present around the stove. |
Safety Protection | 1. When initially using or resuming use after a long period of disuse, an oven-drying process is required for the furnace to prevent cracking of the hearth. 2. Keep clean regularly and check the electrical furnace wiring for good contact periodically. 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 working process, the temperature should generally not exceed 300℃ and the heating rate should not be too fast. This is because when the furnace is initially heated, it is cold and requires a large amount of heat absorption. |
After-Sales Service | We commit to addressing any technical inquiries from customers within 1 hour. 2. We promise to provide the test results for equipment returned for repair within 1 working day and complete the repair within 3 working days. Special materials require customization and will be handled accordingly. 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 shipment or shortage. 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, 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. These can be repaired using an alumina coating. |
