PRODUCT INTRODUCTION

Product Introduction

The LYL Series Vertical Tube Furnace is a new type of energy-saving and environmentally friendly electric furnace independently developed by Luoyang Liyu Kiln Co., Ltd., incorporating advanced technologies. This equipment features scientific design technology, an elegant appearance, a reasonable structure, and simple, convenient operation.

Applications

This series of equipment is suitable for laboratories and production lines in research institutions, universities, and industrial enterprises.

It is mainly used for high-temperature precision annealing, devitrification, ceramic glaze preparation, mold annealing, powder metallurgy, plastic powder experiments, sintering of nanomaterials, quenching of metal parts, and heat treatment processes requiring high-temperature conditions.

Product Features

Durable Housing: The shell adopts a double-layer structure made of high-quality cold-rolled steel plates. The surface is treated with high-temperature baked paint for long-lasting durability.
Efficient Cooling & Stability: Equipped with an air-cooling system, the furnace offers uniform temperature distribution, low surface temperature, and fast heating/cooling rates.
Advanced Vacuum System: Features a specially designed vacuum system that is easy to operate, offers high vacuum levels, and minimal leakage (Ultimate vacuum: 10⁻⁵ Pa).
Reliable Sealing: The sealing system utilizes stainless steel flanges combined with furnace tubes and high-temperature resistant O-ring silicone rubber seals. Gas flow is controlled by needle valves after passing through flow meters. The system includes intake, exhaust, and vacuum valves, allowing for the filling of inert gases such as Nitrogen and Argon.
Energy-Saving Chamber: The furnace chamber is constructed from imported composite alumina fiber material using CNC technology, saving 30% more energy compared to traditional electric furnaces.
Intelligent Control: The control system adopts microcomputer AI regulation technology, supporting 50 program segments for various heating, soaking, and cooling cycles, ensuring high temperature control accuracy.
Precise Regulation: Utilizes crystal modular thyristor control with phase-shift triggering and high-quality heating elements.
Safety Protection: The digital control panel provides protection against over-temperature, over-pressure, over-current, thermocouple breakage, and power failure.

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.

Optional Accessories List

Separate Control Cabinet	Touch Screen Instrument	Remote Auxiliary Module
Crucible Hook	Reducer Pipe / Reducing Pipe	Rotating/Tilting Furnace Tube
Crucible, Quartz Boat	Pipe Plug / Tube End Cap	Vacuum Pump
Corundum Tube / Quartz Tube	Thermocouple	Centralized Control Industrial PC
Caster Wheel	Multi-point Temperature Measurement	Exhaust Gas Purification Device

Special Note

Item	Content
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.
