Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content that needs to be translated into American English. | Silicon-carbide components, with higher operating temperatures, are hard and brittle. After molding, they are used, such as silicon-carbide silicon-carbide rods and tubes, which can reach a heating temperature of up to... under dry air conditions.1500100-120°C, for use at temperatures up to 1000-1200°C under vacuum conditions; long-term use at 1350°C under nitrogen atmosphere. |
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, 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-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 up on the table or a fiber glass mat. 4. After the experiment, the crucible tongs should be cleaned and placed in the laboratory equipment cabinet for drying. 5. Use the bent section for holding crucibles, and the pointed end for other uses. 6. Crucible tongs may not always be used in conjunction with crucibles; they can also be used independently. | |

Special Note
Quality Assurance | One-year full machine warranty, excluding related consumables (excluding pads and heating elements); lifetime on-site repair service. |
Factory environment | 1. Indoor use 2. Environmental temperature within ±5 to 45℃ range. 3. Relative ambient temperature surrounding 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 first using or after a long period of disuse, an electric furnace must be seasoned to prevent cracking of the furnace chamber. 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 process, the temperature should typically not exceed 300℃ and the rate of temperature increase 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 | 1. We commit to resolving any technical inquiries from our clients within 1 hour. 2. We promise to provide a test result within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials and custom orders on a case-by-case basis. 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 for extended periods at the rated temperature 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 a heating rate and cooling rate of 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, 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. |
