What Is a Crucible Melting Furnace?
A crucible melting furnace uses a heat source to melt metal inside a crucible. The crucible holds the metal charge during melting and allows the molten metal to be poured or transferred after reaching the required temperature.
The WOLFU furnace is designed for non-ferrous metal smelting and holding. It is suitable for aluminum casting plants, copper processing factories, brass melting operations, zinc processing, and metal recycling facilities.
Unlike some induction furnaces, a gas or oil fired crucible furnace can be a good choice when fuel cost, local energy supply, or plant conditions make combustion heating more practical.

How the Furnace Works
Step 1: Prepare the Metal Material
Operators prepare aluminum, copper, brass, zinc, or other non-ferrous metal materials before loading.
Raw material should be checked for moisture, excessive impurities, and unsuitable foreign materials. Cleaner feed material helps improve melting efficiency and final metal quality.
Step 2: Load the Crucible
The prepared metal is placed into the crucible. The crucible should match the metal type, furnace capacity, and operating temperature.
Correct loading helps maintain stable melting and reduces unnecessary process delays.
Step 3: Start Gas or Oil Heating
The combustion system provides high-temperature heat to melt the metal inside the crucible.
Gas or oil heating can be selected according to local fuel availability, operating cost, and customer plant conditions.
Step 4: Hold the Molten Metal
After melting, the furnace can hold molten metal at a stable temperature before casting, pouring, or ingot production.
Stable holding is important for continuous casting work and aluminum ingot production lines.
Step 5: Pour or Transfer the Metal
The molten metal can be poured into molds, transferred to casting equipment, or used in downstream metal processing.

How to Choose the Right Model
Choose by Metal Type
Aluminum, copper, brass, and zinc have different melting temperatures and process requirements. Before selecting a furnace, confirm your main material first.
Choose by Capacity
Small workshops may choose 0.1T, 0.25T, or 0.35T models. Medium production plants may choose 0.5T, 0.75T, 1T, 1.5T, or 2T configurations.
Choose by Fuel Source
If gas is more economical and stable in your area, a gas-fired configuration may be suitable. If oil is more available, an oil-fired system may be more practical.
Choose by Production Workflow
If your plant needs only batch melting, a smaller furnace may be enough. If your plant connects with an ingot casting line or continuous production process, a larger furnace may be more suitable.
