Equipment Brief Introduction
The large electric loom furnace LYL-14HSLD incorporates advanced technology and is self-developed and produced, a new energy-saving and environmentally friendly electric furnace. The equipment features an aesthetically pleasing and practical design, with an advanced and reasonable structure. It is easy to operate and is made of high-quality cold-rolled steel plate, processed by precise CNC machine tools. The luxurious and beautiful two-color imported epoxy powder electrostatic spray paint is used in the manufacturing process, ensuring high-temperature resistance, corrosion resistance, and long-lasting color retention.
The furnace features uniform temperature distribution, a double-layer heat-insulating body with surface temperatures close to room temperature, and adjustable heating rates. The furnace chamber is constructed from imported ultra-high-temperature composite fiber materials using CNC technology, offering strong resistance to thermal shock, excellent resistance to rapid cooling and heating, good corrosion resistance, no collapse, no crystallization, no slagging, no pollution, and a long service life.
The control system employs microcomputer intelligent adjustment technology, featuring PID regulation, automatic control, self-tuning capabilities, multi-programming, and the ability to program various heating, constant-temperature, and cooling programs. It boasts high temperature control accuracy, high energy efficiency, and high stability.
Protective devices feature independent protection: (over-temperature, over-pressure, over-flow, un-matching, power failure, leakage, short-circuit, etc.).
The furnace material conveyor is electrically operated, allowing it to 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, start/stop the furnace, set temperature control programs, store control programs, view historical curves, and print historical curves.

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 electronics, ceramics, magnetic materials, glass, metallurgy, refractory materials, etc. | |
Pot tongs | | 1Please provide the Chinese content you would like translated into American English. | A common chemical instrument, typically used to pick up crucibles. Usually 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, the crucible tongs should be cleaned and placed in the laboratory equipment cabinet, allowing them to dry. 5. Use the bent section for holding crucibles; use the pointed tip for other purposes. 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 repair service. |
Factory environment | 1. For indoor use; 2. Environmental 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 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 furnace chamber from cracking. 2. Keep the furnace clean regularly and check that the electrical connections are well-seated. 3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. It is prohibited to pour flammable liquids or melted 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, when initially heating, the furnace is cold and requires a significant amount of heat absorption. |

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 on a case-by-case basis. 3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendship Reminder | Do not operate the equipment continuously for extended periods to ensure its normal service life.NoneSet 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 a heating and cooling rate of 10℃/min. 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 some time of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect its operation. These can be repaired with an alumina coating. |
