Box Furnace (Tube-Type Dual-Purpose High-Temperature Furnace)

This product combines the functions of a box furnace and a tube furnace in one unit.

Box furnace and tube furnaces typically require separate configurations in traditional laboratories, which takes up space and increases costs. This product integrates both functions into one device, allowing users to flexibly switch between operating modes according to their experimental needs.

When used as a box furnace, the spacious furnace chamber is suitable for sintering and heat treatment of bulk samples, irregularly shaped parts, and batches of samples. When used as a tube furnace, it can introduce protective gases, reducing gases, or reactive gases, making it suitable for experiments involving powder materials, thin film materials, and those requiring heat treatment under specific atmospheres.

Product Features

1.Dual-Purpose Functionality, Economical and Affordable

Traditional muffle furnaces only function as box furnaces. For atmosphere experiments, a separate tube furnace is required. This product combines the functions of a box furnace and a tube furnace, performing the work of both types of furnaces.

2.Customizable Sizes, Multiple Furnace Tube Options

The length of the furnace tube heating zone and the size of the furnace chamber can be customized according to customer requirements. Furnace tubes can be selected from quartz glass tubes, high-purity corundum tubes, or various types of metal tubes depending on experimental needs.

3.Box-to-Tube Switching

The equipment is designed with a convenient switching structure. Switching from box furnace mode to tube furnace mode requires no complicated disassembly or assembly, making operation simple and quick.

4.360° Rotating Furnace Door

The furnace door can rotate 360° after opening, moving it to the side to prevent the hot furnace door from directly facing the operator, effectively preventing burns.

5.Adjustable Sealing Bolts

The furnace door features a sealing bolt design, allowing for adjustable sealing as needed. This enhances sealing during atmosphere experiments to ensure a stable atmosphere within the furnace; during normal sintering, adjustments can be made to maintain ventilation. This box furnace balances flexibility and reliability in terms of sealing performance.

6.High-Quality Lining Material

The furnace lining utilizes a multi-layered structure of high-purity alumina fiber, offering advantages such as high operating temperature, low heat storage, resistance to rapid heating and cooling, and resistance to cracking and slag shedding. Its excellent insulation properties effectively retain heat within the furnace, resulting in significantly lower energy consumption compared to traditional refractory brick muffle furnaces.

Box furnace/Tube-Type Dual-Purpose Furnace – Frequently Asked Questions (FAQ)

1. Can this furnace really be used as two separate units?

Yes. The box-type furnace mode processes lumpy samples, while the tube-type furnace mode, with the furnace tubes, processes powder samples or provides atmosphere protection. They share a single temperature control system, making switching easy.

2. How do I use the sealing bolts?

Manually tighten the bolts after closing the door. Over time, the seal may weaken; simply tighten them slightly. No tools are needed.

3. What types of furnace tubes are available? How do I choose?

Quartz tubes: Below 1200℃, transparent for sample observation; Corundum tubes: Below 1600℃, high temperature and corrosion resistant; Metal tubes: Below 1000℃, rapid heating and cooling.

4. Can the furnace chamber size and heating zone length be customized?

Yes. Just tell us the required dimensions and temperature when placing your order.

5. What information is needed for customization?

Maximum temperature, furnace tube heating zone length or furnace chamber size, sample type, and whether atmosphere protection is required.
