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. Thus, silicon molybdenum rods exhibit 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 |

Usually 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 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 portion for holding crucibles; for other uses, employ the pointed tip. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used alone. | |

Factory environment | 1. Indoor use 2. The ambient temperature is within ±5-45°C 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 initially using or resuming use after a long period of disuse, the furnace must be dried out to prevent cracking of the furnace chamber. 2. Keep the equipment clean and regularly inspect the electrical furnace wiring for secure contact. 3. When using the 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 is cold at the beginning and requires a significant amount of heat absorption. |

Friendly Reminder | Do not operate the equipment continuously 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 service life of the instrument, we recommend that the heating and cooling rates not exceed 10℃/min. Cooling rate should not exceed 5℃/min. 5. This furnace does not have a vacuum-sealed structure; therefore, flammable and explosive gases cannot be introduced. 6. After some use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. These can be repaired using an alumina coating. |
