PRODUCT INTRODUCTION

Product Introduction

The Rotary Tilted Vacuum Atmosphere Tube Furnace incorporates advanced technologies and is an independently developed, energy-saving, environmentally friendly, and novel electric furnace. It features an advanced and rational structure with an elegant appearance. 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 and corrosion resistance. It utilizes high-quality joint-venture resistance wires, silicon carbide rods, or silicon molybdenum rods as heating elements. A forced-air cooling system between the double-layer furnace shell allows for rapid cooling. The furnace boasts advantages such as uniform temperature distribution, low surface temperature, adjustable heating, soaking, and cooling rates, and energy efficiency.

The furnace chamber is constructed from composite alumina 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 computer-based artificial intelligence regulation technology, featuring PID adjustment, automatic control, and self-tuning functions. It supports multi-stage program programming for various heating, soaking, and cooling cycles, ensuring high temperature control accuracy. It utilizes integrated module thyristor control with phase-shift triggering. The protection system includes independent safeguards against over-temperature, over-pressure, over-current, leakage, and short circuits. With a high degree of automation, all indicators meet advanced international standards.

This equipment is widely used in universities, research institutes, and industrial enterprises for experiments and production involving powders, electronics, metallurgy, pharmaceuticals, ceramics, new glass materials, chemicals, metal sintering, and metal heat treatment.

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.
