Annealing Furnace

About Annealing Furnace

Annealing Furnace manufactured by United Enterprises is a versatile heat treatment furnace used to soften metals, refine grain structure, relieve internal stresses and restore ductility after cold working.

Brief Description:

Annealing is one of the most common heat treatment processes in metalworking. Our annealing furnaces are designed for steel, stainless steel, copper, brass, aluminium and specialty alloy products in coil, plate, wire, tube or component form. Configurations include box, chamber, bogie, bell, roller hearth, mesh belt and pusher types.

Where bright finish is required, we supply the furnace with our in-house Ammonia Cracker or Hydrogen Generator to maintain a reducing atmosphere. Electric and recuperative gas-fired versions are both available, with multi-zone PLC temperature control.

Each furnace is engineered around the customers product, throughput, atmosphere and target metallurgy.

Characteristics:

• Versatile annealing for steel, SS, copper, brass, aluminium
• Box / chamber / bogie / bell / belt / pusher configurations
• Maximum temperature up to 1200C
• Available in electric and recuperative gas-fired versions
• Reducing or inert atmosphere via in-house gas generators
• Multi-zone PLC temperature control
• Low-density high-quality refractory insulation
• Fully automated SCADA system with recipe storage

About United Enterprises:

United Enterprises is among the top annealing furnace manufacturers in India with over 25+ years of experience in heat treatment systems. We design, manufacture, supply, export and commission tailor-made annealing furnaces across Asia and Europe. Our turnkey approach, in-house atmosphere generator manufacturing and CE / ISO compliance support customers in stainless steel, copper, automotive, aerospace and engineering industries.

FAQs:

Q: Which annealing furnace type is right for me?

A: Depends on product form (coil, plate, wire, tube, components) and volume. Our engineers help select between box, bogie, bell, belt or pusher types.

Q: Bright annealing or open annealing?

A: Bright annealing in reducing atmosphere is needed where surface finish matters; open annealing is simpler and used where surface finish is not critical.

Q: Do you supply with gas generators?

A: Yes. Ammonia Cracker, Endo Gas, Exo Gas, Nitrogen and Hydrogen generators are all built in-house and supplied with our annealing furnaces.

Advanced Temperature Control for Precision Annealing

Benefit from the furnace's digital PID controller, which enables programmable temperature profiles to meet specific heating requirements. This results in consistent, high-quality annealing for glass or metal parts, minimizing thermal stress and ensuring precise material properties. The automatic temperature control system facilitates ease of use and optimal process management.


Engineered for Safety and Reliability

Safety is paramount; the furnace is equipped with over-temperature protection, safety interlocks, and durable construction. The ceramic insulation and powder-coated, mild steel chamber enhance operational safety while reducing heat loss, leading to energy savings. These features make the furnace suitable for rigorous industrial environments where reliability cannot be compromised.


Flexible Design and Efficient Operation

Available in various capacities, power ratings, and customizable dimensions, this furnace adapts to diverse industrial needs, handling glass up to 1200 mm wide. Optional forced air or water cooling accelerates the process, optimizing production time. The energy-efficient design supports sustainable, cost-effective operation in large-scale and small-scale manufacturing settings.
