Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with higher operating temperatures, are hard and brittle, and are used after molding. For instance, silicon carbide rods and tubes, after being shaped, can reach high heat temperatures in air-dry conditions.1500Operating temperature 1000-1200°C under vacuum conditions, long-term temperature 1350°C under nitrogen atmosphere. |
Silicon Molybdenum Rod |
| 2Branch | Silicon molybdenum rods are heated to high temperatures under an oxidizing atmosphere, forming a dense quartz glass film on the surface to prevent further oxidation. Thus, silicon molybdenum rods possess high-temperature oxidation resistance. Under 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. | |
Tongs for crucibles |
| 1Please provide the Chinese content that needs to be translated into American English. | A common chemical instrument, typically used to pick up 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 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 thoroughly and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent portion for holding crucibles, and the sharp tip for other applications. 6. Crucible tongs are not necessarily used with crucibles; they can also be used independently. | |

Factory environment | 1. Indoor use 2. Environmental temperature is within ±5-45℃ range. 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulate corrosive gases around the stove. |
Safety Protection | 1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to perform a drying operation; otherwise, it may easily cause the furnace chamber to crack. Keep clean regularly and check the electrical furnace wiring for good contact. 3. Do not exceed the rated temperature when using the furnace to prevent damaging the heating element. It is strictly prohibited to pour flammable liquids or melted metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the heating rate should be moderate, as the furnace is cold at the beginning and requires a significant amount of heat to absorb. |

We commit to providing test results within 1 business day for equipment returned for repair, completing repairs within 3 business days, and for special materials, handling 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 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 missing items. 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, thus flammable and explosive gases cannot be introduced. 6. After a period of use, the furnace may develop minor cracks, which is a normal occurrence and will not affect its operation. These can be repaired using an alumina coating. |
