Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with high usage temperatures, are hard and brittle. After shaping, they are used, such as silicon carbide rods and tubes, which can reach high heating temperatures under air-dry conditions.15001000-1200°C under vacuum conditions, long-term use temperature of 1350°C under nitrogen atmosphere |
Silicon Molybdenum Rod |
| 2Please provide the Chinese content to be translated. | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface to protect them from further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. In an oxidizing atmosphere, temperatures can reach1800℃, can be used as heating elements for industrial high-temperature furnaces in electronics, ceramics, magnetic materials, glass, metallurgy, refractory materials, etc. | |
Pot tongs |

Factory environment | 1. Indoor use 2. Environmental temperature: ±5 to 45°C range. 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or corrosive gases that can severely damage metals and insulation are present around the stove. |
Safety Protection | 1. When initially using or restarting 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 the equipment clean and regularly inspect the electrical furnace wiring for secure connections. 3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. It is strictly prohibited to pour flammable liquids or 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. This is because, when heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |

Friendly Reminder | Do not operate the equipment continuously for extended periods to ensure its normal service life.AmountSet temperature. 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 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 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 with an alumina coating. |
