Furnace Introduction

A calcining furnace is an industrial equipment mainly used for thermal treatment of various solid materials to alter their physical or chemical properties, without involving the melting process.

In actual production, different structural types are designed, including drum-type structures suitable for continuous production, as well as customized box-type, well-type, and trolley-type structures.

Purpose of the calcining furnace

Widely used in various industries such as metal processing, mineral treatment, ceramic manufacturing, and chemical engineering.

Roasting typically includes oxidation, pyrolysis, reduction, and halogenation, with catalysts sometimes added during the process.

Suitable for calcining various non-metallic materials such as catalysts, fluxes, and molecular sieve calcination, as well as drying and calcining of various mineral products like rare earth and bauxite ore.

Furnace equipment features

(For example, a trolley-type catalyst calcination furnace)

Robust and durable furnace structure

The outer shell steel structure is tightly welded from steel plates and shaped steel sections, with a durable furnace body structure and reinforced by combined channels.

Easily installed with no need for foundation excavation; simply place on the ground and secure with bolts.

Expertly designed heating elements

The heating element consists of a specially formulated high-temperature alloy resistive strip, rationally arranged on all five sides of the furnace for even temperature distribution.

Excellent antioxidant properties, high-temperature resistance, and high load capacity. Heat without cracking at ultra-high temperatures, maintenance-free year-round.

Excellent thermal insulation properties

The furnace chamber is constructed with high-purity ceramic fiber high-pressure modules, featuring non-deforming multi-anchor fixation, ensuring superior thermal insulation performance in the manufacturing of the furnace lining.

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

Stable furnace door, good sealing properties

The gantry structure is sturdy and durable, with stable up and down operation of the furnace door. The track is self-weighted and tightly sealed, offering strong sealing performance.

Equipped with an electric lifting double guide rail automatic sealed furnace door, full fiber insulation structure with sealing ring, no damage to the masonry.

Specialized ceramic bowl for powdered materials, enhancing production efficiency
