After molding, they are used, such as silicon carbide rods and tubes, which can reach high heating temperatures under air-dry conditions.15001000-1200℃ under vacuum conditions, long-term use temperature of 1350℃ under nitrogen atmosphere |
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, 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 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 to hold crucibles. Generally made of stainless steel or hard, non-combustible, and non-oxidizable materials. 2. Use clean tongs. 3. When handling a hot crucible with tongs, preheat the tips to prevent the crucible from cracking due to local cooling. After use, place the tongs with the tips facing up on the table or on a asbestos pad. 4. After the experiment is complete, clean the crucible tongs and place them in the equipment cabinet for drying. 5. Use the bent section for holding crucibles; for other uses, use the pointed end. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Factory Environment | 1. Indoor Use 2. Environmental temperature 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 cause insulation corrosion are present around the stove. |
Safety Protection | 1. When initially using or resuming use of an electric furnace after a long period of disuse, it is necessary to dry the furnace 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 various flammable liquids and molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate, as the furnace chamber is cold at the beginning and requires a significant amount of heat to be absorbed. |
After-sales service | 1. We promise to address any technical inquiries from our clients within 1 hour. 2. We promise to provide the test results within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials on a case-by-case basis. 3.

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. 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, this furnace may develop minor cracks in the combustion chamber, which is a normal occurrence and will not affect its operation. It can be repaired using an alumina coating. |
