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, 1350°C long-term use temperature 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, 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 fields such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles |
| 1Please provide the Chinese content to be translated. | 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 of the tongs to prevent the crucible from cracking due to local cooling. After use, place the tongs with the tip facing up on the table or a asbestos 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 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 alone. | |

Special Note
Quality Assurance | One-year full machine warranty, excluding related consumables (excluding pads and heating elements)Lifetime On-Site Maintenance |
Factory environment | 1. For indoor use; 2. 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 to prevent cracking of the furnace chamber. 2. Keep the electric furnace clean and regularly inspect the wiring connections 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 temperature increase should be moderate. This is because, when heating up initially, the furnace is cold and requires a significant amount of heat absorption. |

Friendly Reminder | Do not operate the equipment continuously for an extended period 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; 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. |
