Equipment Brief Introduction
The LYL-17ZTL series vacuum furnace equipment is mainly used for vacuum sintering, quenching, and other processes of hard alloy, magnetic materials, ceramics, and powder materials. The high-temperature sintering process for materials ensures reliable thermal and insulating properties design. The new electrode structure eliminates the leakage issue of high-temperature furnace electrodes, and the replaceable parts in the heating system are easier to maintain and replace.
Primary Application
This equipment is widely used in universities, research institutes, industrial and mining enterprises, and is the ideal equipment for experiments and production in fields such as powder, electronics, metallurgy, ceramics, sulfur, new glass materials, chemicals, metal sintering, and metal heat treatment.

Vacuum System DescriptionVaccum System）
The vacuum system is a diffusion pump unit, consisting of a diffusion pump and a scroll-type Roots vacuum pump. It includes a high-vacuum diffusion pump, water-cooled baffle, scroll vacuum pump, electromagnetic vacuum gas-in valve, high-vacuum pneumatic baffle valve (main valve), high-vacuum pneumatic baffle valve pre-evacuation valve, high-vacuum pneumatic baffle valve (exit valve), preliminary pipeline gas-in valve, connecting pipeline, sealing ring, composite vacuum gauge, and electrical control cabinet, etc., forming a pumping system.
2. This unit is not suitable for extracting gases that are corrosive to metals or react chemically with pump oil. It can serve as a high vacuum acquisition device for high-tech equipment such as vacuum smelting, vacuum sintering, vacuum heat treatment, vacuum coating, vacuum brazing, and space simulation experiment facilities. Operating environmental temperature: 5~40°C, relative humidity not exceeding 85%, cooling water temperature: 25°C ±5°C.
3. The vacuum level is related to the vacuum pump's suction capacity, the cabin's sealing, and the degassing amount of the cabin's internal materials (furnace inner wall, experimental devices, heat sinks, etc.). The ultimate pressure of this unit is 1×10^-3 Pa, the operating pressure is 1×10^-2 Pa, and the suction time is approximately 1 hour.
4. The diffusion pump cannot evacuate air independently; it must be operated in conjunction with a priming pump that reduces the system pressure to within the startup pressure required by the diffusion pump, typically ≤10 Pa.
5. A new water-cooled baffle is installed at the intake of the diffusion pump, effectively preventing the return of oil vapor from the pump into the vacuum chamber, thus avoiding contamination of the experimental equipment.
6. To prevent the vacuum oil in the primary pump from flowing back into the diffusion pump cavity when the pump stops, an electromagnetic valve must be installed at the inlet of the primary vacuum, automatically isolating the system piping during shutdown.
7. Valves are all operated pneumatically for easy handling.
8. Upon initiating the vacuum pump, this system is equipped with a preliminary evacuation line, through which the gas to be pumped is directly extracted by the fore pump, bypassing the diffusion pump. This method prevents contamination of the diffusion pump by the gas inside the container (moisture, volatiles, impurities). Once the pressure inside the container drops to 10 Pa, close the preliminary evacuation valve and open the baffle valve, and the diffusion pump will begin normal evacuation of the container.

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 tips of the tongs first to prevent the crucible from cracking due to localized cooling. After use, place the tongs with the tips facing up on the table or a fiber glass mat. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying. 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. | |

Factory environment | 1. Indoor Use 2. Environmental temperature: ±5-45℃ range 3. Relative ambient temperature does not exceed 85%. 4. No conductive dust, explosive gases, or gases capable of severely damaging metals and insulating materials are present around the furnace. |
Safety Protection | 1. When initially using or resuming use after a long period of disuse, the furnace must be baked to prevent cracking of the furnace chamber. 2. Keep clean regularly and check the electrical furnace wiring for good contact periodically. 3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. It is prohibited to pour various flammable liquids and molten metals into the furnace. 4. During the process, the temperature should typically not exceed 300℃ and the heating rate should be moderate. This is because, initially, as the furnace is cold, it requires a significant amount of heat absorption. |
