Heating Element | Silicon carbide rod |
| 2Zhi | Silicon-carbide components, with high usage temperatures, are hard and brittle, and are used after shaping. For example, silicon-carbide silicon-carbon rods and tubes can reach high heat temperatures under dry air conditions.15001000-1200℃ under vacuum conditions, long-term use temperature of 1350℃ under nitrogen atmosphere |
Silicon Molybdenum Rod |
| 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface to prevent further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800℃, can be used as heating elements for industrial high-temperature furnaces in fields such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles |
| 1Return the following foreign trade supply-related content translated into American English, without Chinese content, return as is: [Please provide the Chinese content to be translated.] | A common chemical instrument, usually used for holding crucibles. Generally made of stainless steel or hard, non-flammable, and non-oxidizable materials. 2. Use clean tongs. 3. When handling a hot crucible with tongs, preheat the tips of the tongs to prevent the crucible from cracking due to local cooling. After use, place the tongs with the tips facing up on the table or a asbestos mat. 4. After the experiment, clean the crucible tongs thoroughly and place them in the laboratory equipment cabinet for drying. 5. Use the bent section for holding crucibles, and the pointed end for other uses. 6. Crucible tongs are not necessarily used with crucibles; they can also be used independently. | |

Factory Environment | 1. Indoor use 2. Operating temperature range: ±5 to 45°C 3. Relative ambient temperature surrounding does not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulate corrosive 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 unit clean and regularly inspect the electrical furnace wiring for secure contact. 3. When using an 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 heating rate should be moderate. This is because, initially, as the furnace is cold, it requires a significant amount of heat absorption. |

Friendly Reminder | Do not operate the equipment for extended periods 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 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, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. It can be repaired using an alumina coating. |
