Box Furnace Introduction

Commonly used electric heating elements, also known as box-type resistance furnaces, are a type of energy-saving industrial furnace for periodic operations, and are a common thermal treatment equipment.

The box furnace design is similar to a hollow box structure, featuring an internal heating chamber for placing samples or workpieces to be processed.

A wide range of product types are available, including high-precision, high-uniformity box furnaces, horizontal vacuum box furnaces, and box forging furnaces, etc.

The box furnace series equipment is designed rigorously with a wide temperature range, achieving heat treatment temperatures from 300 to 1700°C.

Box furnace applications

Widely applied in material science, chemistry, ceramic manufacturing, and metal processing industries.

Primarily supply alloy steel products, including various metal molds for normalizing, quenching, annealing, and tempering processes.

Also suitable for process research in high-temperature sintering of diamond saw blades and various materials' ashing for experimental purposes.

Box Furnace Equipment Features

Excellent thermal insulation properties

The furnace chamber is constructed with high-purity ceramic fiber high-pressure modules, featuring multiple anchoring for excellent insulation performance in the lining manufacturing process.

Energy-saving and emission-reduction technology, full fiber structure, rapid internal heating. Low thermal conductivity, low heat capacity, excellent corrosion resistance.

Expertly designed heating elements

The heating element consists of a specially formulated high-temperature alloy resistive tape, which is reasonably arranged on all five sides of the furnace according to an even-temperature design.

Excellent antioxidant properties, high-temperature resistance, and high load capacity. No cracking at ultra-high temperatures, maintenance-free all year round.

Used in aerospace precision heat treatment and other applications, combined with a high-precision temperature control system, it ensures uniformity of furnace temperature within ±3-5℃.

Robust and durable furnace body

The shell steel structure is formed by closely welded steel plates and sections, with a durable furnace body structure and reinforced by combined channels.

EASY INSTALLATION: No need for foundation excavation; simply place on the ground for immediate use.

Lift-type furnace door, stable operation

The gantry structure is sturdy and durable, with stable up and down operation of the furnace door. The track is tightly sealed by its own weight, and has strong sealing performance.

Equipped with an electric lifting double-track automatic sealing furnace door, full-fiber insulation structure with sealing rings that do not damage the masonry.

Side-hinged furnace door, easy to operate
