Trolley Furnace Brief Introduction

The trolley furnace, also known as the trolley-type resistance furnace, is a standard energy-saving periodic operation industrial furnace widely used in the heat treatment process of various metal materials.

This type of industrial furnace takes into account high efficiency and environmental protection requirements, incorporating various energy-saving measures such as full-fiber high-pressure insulation materials, to reduce energy consumption and enhance thermal insulation performance.

Its core feature is a stable trolley at the bottom, which serves as a carrier for loading workpieces, facilitating the handling of bulk or heavy-duty parts.

The equipment boasts good thermal insulation properties, a heavy-duty mobile trolley, easy and quick loading and unloading of workpieces, and a sturdy and durable furnace structure.

Purpose of the trolley furnace

Quenching, annealing, normalizing, tempering, and aging treatments for high-chromium high-manganese steel castings, aluminum alloy materials, metal structural parts, welded components, and alloy steel parts.

The RT4 series trolley furnace is a flagship product of Hankou Furnace Co., Ltd., designed and developed in sync with international industrial furnace technology.

Trolley furnace research and production base, mass production line, equipment for export to international markets and participation in international competition.

Trolley Furnace Equipment Features

Excellent thermal insulation properties

The furnace chamber is constructed with high-grade, high-purity ceramic fiber modules for thermal treatment applications, utilizing high-pressure masonry and multiple anchoring to ensure superior thermal insulation performance in the lining manufacturing process.

Energy-saving and emission-reduction technology, full fiber structure, fast inside furnace heating rate. 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 strip, arranged in a uniform temperature design across the interior of the furnace on five sides.

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

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

Robust and durable furnace body

The outer steel structure is formed by tightly welded steel plates and shaped steel, with a durable furnace body structure and reinforced by combined channel steel.

The trolley track utilizes an integrated rail structure, which can be securely fastened with ground bolts, ensuring the trolley furnace operates without issues for long-term use.

Stable door, good sealing.

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

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

Overloaded trolley, no slag falling off the furnace bottom plate.

Heavy-duty loading trolley with a load capacity of 1-200T, powered by a high-power drive system. The sealed groove features an automatic lifting sand seal mechanism, ensuring effective sealing between the trolley and furnace body.

The trolley surface is made of heavy-duty high-alumina refractory bricks, paired with high-temperature-resistant collision-proof and slag-proof furnace bottom plates, which maintain their shape after long-term use.

Specialty material boxes, enhance production efficiency

Design and manufacture various workpiece crates for quick and easy loading and unloading.

All types of workholding devices, including material boxes, fixtures, and trays, are available.

Complementary high-temperature resistant, impact-proof, and non-dust falling furnace bottom plate, maintains shape after long-term use.

Customizable in various furnace structure types, effectively meeting customer needs.

Vacuum car-bottom furnace, suitable for oxidation-free vacuum heat treatment.

Double-door trolley furnace, ensuring continuous and uninterrupted heat treatment.

Flip the trolley furnace for quick immersion quenching of workpieces.
