Equipment Brief Introduction
The LYL-17THL car-bottom furnace with 3 temperature zones incorporates advanced technology, featuring a self-developed energy-saving and environmentally friendly new electric furnace. The equipment boasts an elegant and tasteful design, with an advanced and reasonable structure, easy operation, and a shell made of cold-rolled steel plates. It is precision machined on CNC machines, finished with a luxurious and beautiful two-color imported epoxy powder electrostatic spraying process. It is highly resistant to high temperatures, corrosion, and fading over time.
The furnace features uniform temperature distribution, a double-layer heat-insulating body with surface temperatures close to room temperature, adjustable heating rates, and more. The furnace chamber is constructed using imported ultra-high temperature composite fiber materials and CNC technology, boasting strong resistance to thermal shock, excellent resistance to rapid cooling and heating, good corrosion resistance, no collapse, no crystallization, no spalling, no pollution, and a long service life.
The control system employs microcomputer intelligent adjustment technology, featuring PID regulation, full automatic control, self-tuning capability, multi-program programming, and the ability to set various warming, maintaining temperature, and cooling programs. It boasts high temperature control accuracy, high energy efficiency, and stability.
The protective device utilizes independent protection: (over-temperature, over-pressure, over-flow, misalignment, power failure, leakage, short-circuit, etc.).
The furnace material trolley conveyor is electrically powered, allowing it to pull out of 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, start/stop the furnace, set temperature control programs, store temperature control programs, view historical curves, and print historical curves, etc.

Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with higher operating temperatures, are hard and brittle. After molding, they are used, such as silicon carbide rods and tubes, which can reach high heat temperatures under air-dry conditions.15001000-1200℃ under vacuum, 1350℃ long-term use under nitrogen atmosphere |
Silicon Molybdenum Rod |
| 2Please provide the Chinese content that you would like to have translated into American English. | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface, protecting them from 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 sectors 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 localized cooling. After use, place the tongs with the tip facing up on the table or a asbestos pad. 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; for other uses, employ the pointed tip. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Special Note
Quality Assurance | One-year warranty on the entire unit, excluding related consumables (mat boards and heating elements excluded).Lifetime On-Site Maintenance |
Factory environment | 1. Indoor use; 2. Environmental temperature: ±5-45°C range 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the furnace. |
Safety Protection | 1. When initially using or resuming use after a long period of disuse, an electric furnace must be seasoned to prevent the hearth from cracking. Keep clean regularly and check 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 any flammable liquids or 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, at the beginning of the heating process, the furnace is cold and requires a significant amount of heat absorption. |
After-Sales Service | We commit to addressing any technical inquiries from customers within one hour. 2. We promise to issue the test results for equipment returned for repair within 1 working day, complete the repair within 3 working days, and handle special materials as ordered. 3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendly Reminder | Do not operate the equipment at the rated 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 shortages or omissions. 3. To extend the lifespan of the instrument, we recommend not exceeding a temperature rise and fall rate of 10℃/min. 4. The cooling rate should not exceed 5℃/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. Repairs can be made using an alumina coating. |
