PRODUCT INTRODUCTION

Equipment Introduction (Brief Introduction)

The LYL-14MJ Touch Screen Pit Lifting Furnace incorporates advanced technologies and is an independently developed, energy-saving, environmentally friendly, and novel electric furnace. It features an elegant appearance, advanced and rational structure, and simple, convenient operation. The outer shell is constructed from high-quality cold-rolled steel plates processed by advanced CNC machine tools and finished with a luxurious, aesthetic dual-color imported epoxy powder electrostatic spray molding process, offering high-temperature resistance, corrosion resistance, and long-lasting color retention.

The furnace boasts advantages such as uniform temperature distribution, double-layer heat-resistant walls keeping the surface temperature close to room temperature, and adjustable heating rates. The furnace chamber is constructed from imported high-temperature composite fiber material using CNC technology, providing strong thermal shock resistance, excellent resistance to rapid cooling and heating, good corrosion resistance, and preventing collapse, crystallization, or slagging. It ensures no pollution and a long service life.

The control system adopts microcomputer intelligent regulation technology, featuring PID adjustment, fully automatic control, and self-tuning functions. It supports multi-stage program programming for various heating, soaking, and cooling cycles, ensuring high temperature control accuracy, high energy efficiency, and high stability.

The protection system features independent safeguards against over-temperature, over-pressure, over-current, thermocouple breakage, power failure, leakage, and short circuits.

Additionally, via our independently developed control software, the furnace can be connected to a computer to realize remote control of single or multiple furnaces, including starting/stopping the furnace, setting/storing temperature control programs, viewing historical curves, and printing historical data.

Main Application

This equipment is primarily used for the processing and manufacturing of dental porcelain powder. Unlike traditional muffle or crystallizing furnaces, this model features side-wall heating, resulting in a more uniform temperature field. This ensures better translucency and consistency of the sintered crowns. The user-friendly bottom-loading mode allows for convenient loading and unloading of materials, making it an ideal choice for denture processing factories.

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.
