Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with high operating temperatures, are hard and brittle. After molding, they are used, such as silicon carbide rods and tubes, which can reach high heating temperatures under air-dry conditions.1500100-120°C, for vacuum conditions; 1000-1200°C under nitrogen atmosphere; long-term use temperature 1350°C |
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 coating 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. | |
Crucible tongs |
| 1Please provide the Chinese content to be translated. | 1. A common chemical instrument, typically used for holding crucibles. Generally 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 with the tip facing up on the table or a fiber glass mat. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent section for gripping crucibles, and the pointed end for other uses. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Safety Protection | 1. When initially using or resuming use after a long period of disuse, the furnace must be seasoned to prevent cracking of the furnace chamber. 2. Keep the equipment clean and regularly inspect the electrical furnace wiring for good contact. 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 heating should be moderate, as the furnace chamber is cold at the beginning and requires a significant amount of heat absorption. |

Friendship Reminder | Do not operate the equipment at the set 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 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; 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 furnace chamber, which is a normal occurrence and will not affect its operation. It can be repaired using an alumina coating. |
