SVS(G)–5.17.6/5.5

Electric crucible furnace SVS(G)–5.17.6/5.5 is designed for lead plating — a type of chemical-thermal treatment — in a non-oxidizing environment at temperatures up to 550 degrees.

The technologies of lead plating in a non-oxidizing environment (up to 550°C), implemented on equipment manufactured by Tula-Term, process features, usage examples, and operation technology are described in the equipment description article on the company blog.

This is a complete technological solution for applying lead coatings.

The electric furnace SVS(G)–5.17.6/5.5 creates a stable non-oxidizing atmosphere (<5 ppm O₂), completely eliminating surface oxidation of parts, which is essential for good adhesion.

Design Features:

• Full environment control: A special design with technical inert gas supply (nitrogen, argon) ensures operation in a non-oxidizing environment — the main condition for high-quality coating.
• Precision and repeatability: The programmable "Termodat" controller and monitoring system ensure melt temperature stability with an accuracy of ±5°C. All parameters are recorded for analysis.
• Adaptability to your alloys: The furnace includes separate temperature profiles for pure lead, Pb-Sn, Pb-Sb alloys, and others.
• Safety and reliability: Multi-level protection: leak monitoring, emergency thermocouples, overheat and purge systems. Durable lining and long-lasting heaters.
• Process efficiency: Well-thought-out ergonomics with loading, processing, and cooling zones minimize manual labor and heat loss.

Application Areas

The equipment is intended for technologists, thermal engineers, and production managers in the fields of:

• Mechanical engineering and automotive industry.
• Bearing and antifriction component manufacturing.
• Electrical engineering and instrumentation.
• Processing of fasteners and critical metal components.

Application Recommendations

The lead plating process in the SVS(G)–5.17.6/5.5 furnace is a clear sequence of stages: from preparation and heating in a controlled environment to holding in the melt and multi-stage cooling. We provide you not only with equipment but also with standard technological instructions, including:
