Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with high-temperature usage and hardness, are brittle and are used after shaping, such as silicon carbide rods and tubes, which can reach a heating temperature of up to... under dry air conditions.1500100-120°C, for use under vacuum conditions; 1000-1200°C under nitrogen atmosphere; long-term use temperature 1350°C |
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 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 fields such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles |
| 1Please provide the Chinese content to be translated. | 1. 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 tip 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; use the pointy end for other applications. 6. Crucible tongs may not necessarily be used with crucibles, and can also be used independently. | |

Special Note
Quality Warranty | One-year full machine warranty, excluding related consumables (excluding pad boards and heating elements), lifetime on-site maintenance service. |
Factory Environment | 1. Indoor use 2. Environmental temperature: ±5 to 45℃ 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 cause insulation corrosion are present around the stove. |
Safety Protection | 1. When an electric furnace is first used or after a long-term shutdown, it must be seasoned to avoid the risk of the furnace chamber cracking. Keep the equipment clean and regularly inspect the electric furnace wiring for secure contact. 3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. Prohibition of pouring any flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the heating rate 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 | We promise to address our customers' technical queries within 1 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 make special materials to be ordered and 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 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 some use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. It can be repaired using an alumina coating. |
