PRODUCT INTRODUCTION

Equipment Introduction

The LYL-20YMSL Industrial Elevator Furnace integrates advanced imported technology with in-house R&D, resulting in an energy-saving and environmentally friendly electric furnace. The unit boasts an aesthetically pleasing appearance, an advanced and rational structure, and simple, convenient operation. Its shell is made from high-quality cold-rolled steel plate, precision-machined by CNC equipment, and finished with a luxurious, attractive, and durable two-tone imported epoxy powder electrostatic coating, offering high-temperature resistance, corrosion resistance, and long-lasting color retention.

The furnace features a uniform temperature field, a double-layer insulated furnace body with a surface temperature close to ambient, and adjustable heating rates. The furnace chamber is constructed from imported high-temperature composite fiber material using CNC-based processes, providing strong thermal shock resistance, excellent resistance to rapid heating and cooling, good corrosion resistance, and resistance to collapse, crystallization, and slag shedding. It is non-polluting and has a long service life.

The control system utilizes microcomputer-based intelligent regulation technology, featuring PID control, full automation, self-tuning functions, and multi-segment programmable cycles for creating various heating, holding, and cooling profiles. It offers high temperature control accuracy, high energy efficiency, and excellent stability.

The protection system employs independent safeguards for overtemperature, overpressure, overcurrent, thermocouple break, power failure, leakage, and short circuit.

The furnace hearth platform is elevator-type and can be electrically driven out of the furnace body, facilitating material loading and unloading and improving work efficiency.

Furthermore, via our self-developed control software, the furnace can connect to a computer, enabling remote control (single or multiple furnaces), furnace startup/shutdown, temperature program setting and storage, historical curve viewing, and printing.

STANDARD ACCESSORIES

Standard Accessories

Name		Picture	Quantity	Description
High-temperature Gloves			1 pair	Excellent comfort, keeps hands warm; Cut-resistant, abrasion-resistant, and heat-resistant (withstands contact with 350°C heat for 60 seconds, 100°C heat for 180 seconds). Durable.
Heating Elements	Silicon Carbide Rods		2 pieces	Silicon carbide elements, characterized by their high operating temperature, hardness, and brittleness, are ready for use after formation. For instance, silicon carbide rods and tubes, made from silicon carbide, can achieve a heating temperature of up to 1500°C under dry air conditions. Under vacuum conditions, the operating temperature ranges from 1000°C to 1200°C, while in a nitrogen atmosphere, the long-term use temperature reaches 1350°C.
Heating Elements	Silicon Molybdenum Rods		2 pieces	Silicon molybdenum rods, when heated to high temperatures in an oxidizing atmosphere, form a dense layer of quartz glass on the surface, protecting them from further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. In an oxidizing atmosphere, they can reach temperatures up to 1800°C, making them suitable as heating elements for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractories.
Crucible Tongs			1 piece	1.A common chemical instrument typically used for handling crucibles. Generally made of stainless steel or other non-flammable, oxidation-resistant hard materials. 2.Clean crucible tongs must be used. 3.When using crucible tongs to pick up a hot crucible, the tips should be preheated first to prevent the crucible from cracking due to localized cooling. After use, the tongs should be placed on a table or asbestos mat with the tips facing upward. 4.After the experiment, crucible tongs should be cleaned, dried, and stored in the laboratory equipment cabinet. 5.Use the curved section for gripping crucibles; the tips are for other purposes. 6.Crucible tongs are not necessarily used exclusively with crucibles; they can also be used independently.

Factory Environment	1. Indoor use; 2. Ambient temperature range: ±5~45℃; 3. Relative humidity of surrounding environment does not exceed 85%; 4. No conductive dust, explosive gases, or gases that can severely damage metals and insulating materials around the furnace.
Safety Protection	1. When using the electric furnace for the first time or after long-term shutdown, baking is required; otherwise, it is easy to cause furnace cracking. 2. Keep clean regularly and check whether the furnace wiring is in good contact. 3. When using the electric furnace, the furnace temperature shall not exceed the rated temperature to avoid damaging the heating elements. It is forbidden to pour various flammable liquids and molten metals into the furnace. 4. During operation, generally below 300℃, the heating rate should not be too fast, because the furnace chamber is cold at the beginning of heating and needs to absorb a lot of heat.
Friendly Tips	1. To ensure the normal service life of the equipment, please do not run at the rated temperature for a long time. 2. Carefully check and verify the quantity of goods and accessories upon receipt to avoid inconvenience caused by missing or incorrect items. 3. To extend the service life of the instrument, we recommend a heating rate and cooling rate of 10℃/min. 4. The cooling rate should not exceed 5℃/min. 5. This furnace has no vacuum sealing structure, so flammable and explosive gases must not be introduced. 6. After this furnace has been used for a period of time, slight cracks may appear in the furnace chamber, which is a normal phenomenon and will not affect usage. At the same time, it can be repaired with alumina coating.
