Silicon Molybdenum Rod | | 2Please provide the Chinese content to be translated. | 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 sectors such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles | | 1Please provide the Chinese content that you would like translated into American English. | 1. A common chemical instrument, typically used for gripping 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 laboratory equipment cabinet for drying. 5. Use the bent portion for holding crucibles; for other uses, employ the pointed tip. 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. Ambient temperature 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 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 the furnace chamber from cracking. 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 various flammable liquids or molten 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 heating begins, the furnace is cold and requires a significant amount of heat absorption. |

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 as needed. 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 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 lifespan of the instrument, we recommend not exceeding a heating or cooling rate of 10℃/min. 4. The cooling rate should not exceed 5°C/min. 5. This furnace does not have a vacuum-sealed structure, thus 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. |
