Product Description
The NACSCF range of top loading crucible furnaces is available in 3 sizes with a maximum operating temperature of 1400 °C. They are specifically designed for the smelting of precious metals.
The furnaces are robustly constructed from heavy gauge hollow steel section and zinc coated sheet steel panels. Silicon carbide heating elements surround the chamber sides and are protected by silicon carbide tiles. The hearth is constructed from refractory bricks and silicon carbide tiles. The SCF 1 has a single chamber, all other models have twin chambers with separate lids.
Carbolite also offers a range of cupellation/fire assay furnaces.

Customers can choose from a variety of thermocouple types and automation grades, ensuring optimal usability and data integrity for sensitive smelting tasks.
FAQs of NACSCF - Smelting Furnaces:
Q: How does the NACSCF Smelting Furnace achieve precise temperature control during operation?
A: The furnace utilizes a PID microprocessor control system, working alongside Pt-Rh-B/E/K/S thermocouple types, to maintain stable temperatures up to 1650C with 1C accuracy. This enables precise management of the smelting process and ensures consistent results for both industrial and laboratory applications.
Q: What is the installation process for these smelting furnaces, and where can they be placed?
A: NACSCF smelting furnaces are designed for floor-mounted installation. The installation is straightforward and can be carried out in industrial workshops, foundries, or laboratories, provided there is adequate space and electrical supply matching 220V, 380V, or 415V as required by the model.
Q: When can customers expect delivery of these smelting furnaces after placing an order?
A: The typical lead time for NACSCF smelting furnaces is 4 to 6 weeks from the date of order confirmation. This duration allows for thorough customization and quality assurance in manufacturing.
Q: What types of metals and applications are suited for these furnaces?
A: These smelting furnaces are suitable for a wide range of metal melting and smelting tasks, including processing nonferrous and precious metals, both in research/laboratory settings and in industrial-scale production. Their capacity varies from 5 kg to 500 kg to accommodate diverse operational needs.
Q: How do the available cooling systems enhance furnace efficiency and safety?
A: The furnaces are equipped with either air or water cooling systems that efficiently dissipate excess heat, which helps maintain optimal equipment temperature, enhances operational safety, and prolongs the lifespan of core components such as heating elements and refractory lining.
Q: What are the main benefits of choosing the NACSCF Smelting Furnace over other models?
A: Key benefits include reliable energy efficiency, adaptable heating technologies (induction or resistance), exceptional temperature precision, customized chamber sizes and automation levels, robust construction using mild or stainless steel, and a digitally controlled, user-friendly interface.
