The screw jack furnace LYL-18SMD incorporates advanced technology, featuring a self-developed energy-saving and environmentally friendly electric furnace. The equipment boasts an aesthetically pleasing and advanced structure, easy operation, and is made of cold-rolled steel plate processed by precision CNC machine tools. It is finished with a luxurious and beautiful two-color imported epoxy powder electrostatic spraying process, ensuring high-temperature resistance, corrosion resistance, and long-lasting color retention.
The furnace features uniform temperature field, a double-layer heat-insulating body surface temperature close to room temperature, and adjustable heating rate. The furnace chamber is constructed from imported 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, full automatic control, self-tuning capabilities, multi-stage program programming, 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 utilizes independent protection: (over-temperature, over-pressure, over-flow, un-mating, power failure, leakage, short-circuit, etc.).
The lifting furnace table allows for easy removal of the furnace body electrically, 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, allowing for 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.

Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with high operating temperatures, are hard and brittle, and are used after shaping. For instance, silicon carbide rods and tubes, once molded, can reach high heating temperatures under air-dry conditions.1500100-120°C, for use under vacuum conditions; 1000-1200°C in nitrogen atmosphere; long-term use temperature of 1350°C |
Silicon Molybdenum Rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon molybdenum rods are heated to high temperatures under an oxidizing atmosphere, where a dense quartz glass film forms on the surface to protect them from further oxidation. Thus, silicon molybdenum rods exhibit high-temperature oxidation resistance. Under oxidizing atmosphere, temperatures 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 |
| 1Return | 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 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 is completed, clean the crucible tongs and place them in the laboratory equipment cabinet for dry storage. 5. Use the bent section for holding crucibles; use the pointed end for other applications. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Keep clean and regularly inspect that the electrical furnace connections are securely in place. 3. When using the electric furnace, do not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour various flammable liquids or molten metals into the furnace. 4. During the working process, the temperature should generally not exceed 300°C and the heating rate should be moderate, as the furnace is cold at the beginning and requires a significant amount of heat to be absorbed. |
