Equipment Brief Introduction
High-precision muffle furnace LYL-18LBT incorporates advanced technology, featuring an independently developed energy-saving and environmentally friendly electric furnace. The equipment boasts an elegant and tasteful design, advanced and reasonable structure, and easy operation. The exterior shell is made of cold-rolled steel plate, precision-machined on CNC machine tools, and finished with a luxurious and aesthetically pleasing two-color imported epoxy powder electrostatic spraying process. It is highly resistant to high temperatures, corrosion, and fading.
This furnace features uniform temperature distribution, a double-layer heat-insulating body surface temperature close to room temperature, and adjustable heating rates. The furnace chamber is constructed using imported ultra-high temperature composite fiber materials through CNC technology, offering strong resistance to thermal shock, excellent resistance to rapid cooling and heating, good corrosion resistance, non-collapsed, non-crystallized, non-dripping, non-polluting, and a long service life.
The control system employs microcomputer intelligent adjustment technology, featuring PID regulation, automatic control, self-tuning capabilities, multi-step programing, and the ability to create various heating, constant-temperature, and cooling programs. It boasts high temperature control accuracy, energy efficiency, and stability.
The protective device employs independent protection: (over-temperature, over-pressure, over-flow, uncoupling, power failure, leakage, short-circuit, etc.).
The electric furnace material roller conveyor can pull out the furnace body, facilitating the handling of materials and enhancing work efficiency.
Additionally, through our independently developed control software, the electric furnace can be connected to a computer, enabling remote control of a single or multiple furnaces, starting and stopping the furnace, setting temperature control programs, storing temperature control programs, viewing historical curves, and printing historical curves.

Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800℃, can be used as heating elements for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles |
| 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-flammable, and non-oxidizable materials. 2. Use clean tongs. 3. When handling 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 tip 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 portion for holding crucibles, and the sharp tip for other applications. 6. Crucible tongs are not necessarily used with crucibles; they can also be used independently. | |

Safety Protection | 1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to dry the furnace to prevent cracking of the furnace chamber. 2. Keep clean regularly and check if the electric furnace wiring is in good contact on a schedule basis. 3. Do not exceed the rated temperature when using the furnace to prevent damaging the heating element. Prohibit pouring any flammable liquids or molten metals into the furnace. 4. During the working process, the temperature should generally not exceed 300℃ and the heating rate 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 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 shortages or omissions. 3. To extend the service life of the instrument, we recommend a heating rate and a cooling rate of 10℃/min. 4. The cooling rate should not exceed 5°C/min. 5. This furnace does not have a vacuum-sealed structure, so flammable and explosive gases cannot be introduced. 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. |
