Reliable Crucible Melting Furnace for Foundries and Metal Casting

The WDL-RBL-100 crucible melting furnace is a high-performance electric furnace specifically engineered for the melting of ferrous

metals and alloys with low melting points. It is widely used in metal foundries, alloy production plants, research laboratories, and precision casting workshops.

Thanks to its robust design, energy-efficient heating system, and advanced PID temperature control, this industrial crucible furnace delivers consistent melting quality, high safety standards, and a long service life.

Furnace Structure and Key Features

The furnace body is built with high-strength steel plates and sectional steel, forming a durable cylindrical shell that ensures stable operation. Its furnace lining is carefully designed using aluminum silicate fiber blocks, lightweight refractory bricks, and vermiculite powder, providing excellent insulation and reducing energy consumption.

Heating and Temperature Control

• Equipped with OCr27A17MO2 high-resistance alloy wires, ensuring reliable heating performance.

• Dual thermocouples for precise monitoring of both furnace atmosphere and molten metal temperature.

• Thyristor-based PID control system for accurate regulation, achieving ±3℃ temperature stability.

• Automatic safety shutoff in case of over-temperature or current irregularities.

Graphite Crucible

• Uses premium Vesuvius or Gold Elephant graphite crucibles.

• Resistant to thermal shock, with a service life of 6+ months, depending on usage conditions.

Safety System

• Includes an emergency outlet hole at the furnace base to prevent leakage accidents.

• Built-in soft start-up system ensures smooth heating without power surges.
