16KG Large Capacity Propane Furnace with Tongs Crucible LSMIITTH

Description

Product Overview

The 16KG LSMIITTH propane furnace is engineered for small‑scale foundries, jewelry workshops, and metal art studios that require reliable high‑temperature melting in a compact package. Constructed from 1 mm thick stainless‑steel, the furnace body resists corrosion and withstands the rigors of daily use while providing a sleek, professional appearance.

Equipped with a dual‑burner system delivering approximately 100 000 BTU, the furnace creates a balanced flame that envelops the crucible from both sides, reducing hot‑spot formation and accelerating melt times. Users can reach a maximum temperature of 2 642 °F (1 447 °C), sufficient to melt gold, silver, copper, lead, aluminum and many other alloys commonly used in jewelry and metal casting.

The unit measures 12 inches in diameter and 15 inches in height, weighing only 7 kg (15.4 lb), which makes it easy to transport between workstations or to on‑site locations. Included accessories comprise a set of heat‑resistant tongs and a precision‑machined crucible, delivering a ready‑to‑go melting kit straight out of the box.

Usage

Artists and craftsmen can employ the furnace for a variety of projects, from casting intricate gold pendants to recycling scrap copper into new components. The rapid heating capability allows a typical 1300 °C melt to be achieved within 15‑20 minutes, enabling efficient production cycles in busy workshops.

The furnace’s compact footprint fits comfortably on standard laboratory benches, and its propane fuel source eliminates the need for electricity, making it suitable for remote locations, outdoor demonstrations, or classrooms where safety and ventilation are paramount.

FAQ

What type of propane connection does the furnace require?

The furnace is designed to connect to a standard 1‑pound (16‑ounce) propane cylinder using a quick‑connect regulator that ships with the unit. The regulator reduces cylinder pressure to a safe working level and includes a built‑in safety valve that automatically shuts off the flow if the flame is extinguished. Users should verify that the cylinder valve is fully open and that the regulator is securely attached before lighting the burners. For larger operations, a larger propane tank and a compatible regulator can be used, provided the pressure settings are adjusted according to the manufacturer’s guidelines.

Can the furnace melt aluminum and other low‑melting alloys?

Yes. The furnace’s maximum temperature of 2 642 °F (1 447 °C) comfortably exceeds the melting point of aluminum (1 221 °F or 660 °C) and other low‑melting alloys such as lead, zinc, and tin. Because the dual burners provide uniform heat, aluminum melts quickly and flows smoothly into molds without excessive turbulence. Users should pre‑heat the crucible and use appropriate fluxes to prevent oxidation, especially when working with reactive alloys. The stainless‑steel construction also resists the corrosive effects of molten aluminum, extending the life of the crucible and furnace interior.

How long does it take to reach melting temperature for 1 kg of gold?

When using the standard 100 k BTU dual‑burner configuration, a 1 kg batch of 24‑carat gold typically reaches its melting point (1 948 °F or 1 064 °C) within 15‑20 minutes. The exact time depends on ambient temperature, the condition of the crucible, and the initial temperature of the metal. Pre‑heating the furnace for a few minutes before loading the gold can further reduce melt time. The even flame distribution minimizes hot‑spot formation, ensuring a consistent melt and reducing the risk of alloy segregation.

What safety precautions should be taken when operating the furnace?

Operators should always work in a well‑ventilated area and wear appropriate personal protective equipment, including heat‑resistant gloves, safety goggles, and a face shield. Keep a Class ABC fire extinguisher nearby and ensure that flammable materials are stored at a safe distance. Before lighting the burners, inspect the propane hose and regulator for signs of wear or damage. Never leave the furnace unattended while the flame is active, and always follow the manufacturer’s start‑up and shut‑down procedures. After each use, allow the furnace to cool completely before handling or performing maintenance.

Is the furnace suitable for educational settings?

Absolutely. The furnace’s compact size, propane fuel source, and straightforward operation make it an excellent teaching tool for metallurgy, jewelry design, and materials science courses. Its safety features—including an automatic shut‑off valve and a sturdy stainless‑steel enclosure—provide a controlled environment for students to observe metal melting and casting processes. Instructors can use the included tongs and crucible to demonstrate alloy preparation, while the quick‑heat capability allows multiple demonstrations within a single class period.
