Used Industrial Ovens For Sale

Industrial Furnaces and Ovens

The primary use of industrial furnaces is the treatment of metal materials. Sometimes other materials are treated, such as ceramics and glass. Looking for commercial ovens for sale can be overwhelming with so many industrial options available. Industrial furnaces reach temperatures of 2000°F (1093°C) or higher to create a reaction in treated metals. Industrial ovens operate at much lower temperatures, typically lower than 750°F (400°C). You can view our inventory of used industrial ovens here.

Common brands include Andritz Metals, Benko Products, Despatch Thermal Processing Technology, Inductotherm, Ispen, ITC, N. Ferrara Furnace, RIFCO Industrial Furnaces, SentroTech, Tenova, The Furnace Source, Thyssenkrupp, and Xinyu Technologies.

• Box Furnaces: High-temperature processes like heat treating, calcining, tempering, and more are ideal for these ovens. They are also known as “ash furnaces” when used in a laboratory setting. These commercial ovens for sale have a variety of configurations including swing and vertical lift doors, single and multi-zone chambers, and heat ranges from 1850°F (1010°C) to 3000°F+ (1700°C+). Both electric and gas variations exist.
• Car Furnaces: These furnaces can handle the size and weight of larger manufactured goods, making these industrial ovens for sale ideal for forging, annealing, tempering, and drawing large workpieces. Another name is a car bottom furnace. They are loaded with a forklift or overhead crane and are common in the automotive, military, and aerospace industries.

• Rotary Tube Furnaces: These circular furnaces are known for their versatility which is part of the reason they’re one of our most popular commercial ovens for sale. The continuous rotation during heat treatment makes these used commercial ovens perfect for calcining, drying, and sintering.
• Vacuum Furnaces: Brazing, sintering, annealing, and heat-treatment are all common uses of used industrial ovens. Often, the name includes the intended application. For example, Vacuum Heat-treating Furnace and Vacuum Aluminum Brazing Furnace are both names used by manufacturers to narrow down the intended use. The function that constantly removes air and gas via a pumping system sets this type apart. The process removes contamination and provides a cleaner process environment.

• Annealing: The purpose of the annealing process is to soften the treated material such as relieving stress in steel. A vacuum furnace is often the best choice for annealing, but a car furnace is typical for larger workpieces. Steel is the most common treated material, but glass and other materials can benefit from treatment. Used industrial ovens can serve as great annealing furnaces.
• Ashing: Manufacturers can use some of our industrial ovens for sale as ashing furnaces to burn samples of coal, oils, and petroleum products, to test for the presence of ash, indicating a contaminated sample. Some of our commercial ovens for sale are perfect for chemists looking for an ashing lab furnace. Ash analysis requires the safe heating of materials like food, paint, plastic, and coal.
• Brazing: The brazing process, a popular application for our used commercial ovens, uses a vacuum furnace to melt a compatible filler material between two metals. The melting temperature of the filler material must be lower than the base metals for the brazing furnace process to be successful.
• Forging: Hot forging requires material to reach a particular temperature before the metal is shaped with a hammer or other tools. Forge furnaces heat the workpiece before forging. We have several commercial ovens for sale that can serve as appropriate forging furnaces.
• Heat Treat: Heat treatment alters material in controlled environments. Hardening, tempering, annealing and normalizing are all forms of heat treating. Box, vacuum, car bottom, and more are all technically considered heat treat furnaces.

• Metal Melting: Induction and electric arc are modern-day metal melting furnaces used in foundries. After smelting in a blast furnace, metal can be processed in a used industrial oven serving as a metal melting furnace in preparation for casting.
• Muffle: We have industrial ovens for sale that can function as muffle furnaces, separating treated material from contaminants. Box and tube furnaces are specific types.
• Sintering: Our inventory of commercial ovens for sale includes specialized sintering furnaces for powder metallurgy applications. The process of sintering improves thermal conductivity, strength, and other properties of treated materials. A vacuum, tube, pusher, or walking beam are all sintering furnace types.
• Smelting: Some of our used commercial ovens can be used as blast furnaces for smelting. Smelting furnaces prepare metal for melting, which readies the material for the casting operation.
• Tempering: Hardness from other processes may be excessive, and using a tempering furnace can remove some of the hardness. Excess hardness can be problematic, causing brittleness and breakage. Car furnaces are also great for tempering larger workpieces.
• Tensile Testing: For laboratories seeking commercial ovens for sale, tensile testing models offer precise temperature control for materials research. Strength testing with a tensile testing furnace is extremely useful in such quality control tests. It is possible to measure other material properties during testing.
• Additional applications include Calcination (Calcining), Carburizing, Glass Tempering, Hardening, Induction Holding, Induction Melting, and Metal Melting.
