Equipment Brief Introduction
The LYL-17USZK Stainless Steel Vacuum Atmosphere Sintering Furnace incorporates advanced technology, featuring an independently developed energy-saving, environmentally friendly, and new-type electric furnace with an advanced and reasonable structure, and is aesthetically pleasing. The outer shell is made of cold-rolled steel plate, precision machined on CNC machines, and finished with a luxurious and beautiful two-color imported epoxy powder electrostatic spraying process, which is resistant to high temperatures and corrosion. It uses resistance wire/silicon carbide rod/silicon molybdenum rod as the heating element, a double-layer furnace shell with an air insulation layer, maintaining a low surface temperature of the furnace shell. The furnace boasts an even thermal field, low surface temperature of the furnace body, adjustable heating rate, energy-saving features, and more. The furnace chamber is constructed from ceramic fiber material using CNC technology, with strong resistance to thermal shock, excellent resistance to rapid cooling and heating, good corrosion resistance, no collapse, no crystallization, no slag, no pollution, and a long service life. The control system employs microcomputer artificial intelligence adjustment technology.PIDAdjustable, fully automatic control, auto-tuning function, multi-step program programming, capable of setting various heating and maintenance programs, with high temperature control accuracy; integrated module with silicon-controlled rectifier control, phase shift triggering, and protective system: featuring independent over-temperature protection, over-pressure, over-flow, leakage, short-circuit, and other protection measures. High degree of automation, all indicators reaching advanced levels.
This furnace is equipped with a type 1-8 vacuum pump, and an additional set of condensers is required between the pump and the furnace interface. Working atmosphere: atmosphere protection (compatible with various inert protection atmospheres) with a reserved vacuum interface.

14. Round furnace door; lower surface temperature of the door and body for enhanced safety
15. O-ring seal, four-handwheel extrusion seal, excellent sealing performance. The product is sintered more evenly in the furnace when filled with gas, maintains pressure without leakage for 72 hours, and is convenient to open/close the furnace door. (Traditional square furnace door with screws and rubber gaskets around cannot meet the sealing requirements, wasting gas resources. During the firing process, oxidation occurs, and after long-term use, it is prone to thread slipping, leading to poor sealing performance. Moreover, the sealing capability does not meet the technical requirements.)
16. New model vacuum atmosphere furnace with excellent sealing and specially designed furnace door.
17. Optional oxygen sensor available, capable of measuring exhaust oxygen content (optional for various gas sensors), optional chilled water unit

Thus, 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. | |
Crucible 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 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, clean the crucible tongs thoroughly and place them in the lab equipment cabinet for drying storage. 5. Use the bent section for holding crucibles; use the pointed end for other applications. 6. Crucible tongs may not always be used with crucibles; they can also be used alone. | |

Special Note
Quality Assurance | One-year full machine warranty, excluding related consumables (mold boards and heating elements excluded)Lifetime In-Home Maintenance |
Factory environment | 1. Indoor Use 2. Ambient 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 stove. |
Safety Protection | 1. When first using or restarting after a long period of disuse, an electric furnace must be baked to prevent the furnace chamber from cracking. 2. Keep clean regularly and check the electrical furnace wiring for good contact on a routine basis. 3. Do not exceed the rated temperature when using the furnace to prevent damaging the heating elements. It is prohibited to pour various flammable liquids or molten metals into the furnace. 4. During the process, the temperature should generally not exceed 300°C and the heating rate should be moderate. This is because when the furnace starts heating up, it is cold and requires a significant amount of heat to absorb. |
