Frequently Asked Questions (FAQs)
What is a conveyor furnace?
A conveyor furnace is an industrial heat treatment system in which components are transported continuously through heating, soaking, and cooling zones using an automated conveyor system. It is designed for high-volume production, providing consistent heat treatment, improved productivity, and reduced manual handling.
Depending on the application, conveyor furnaces may use mesh belt, roller hearth, chain conveyor, slat conveyor, overhead conveyor, pusher, or walking beam systems.
Typical applications include annealing, tempering, hardening, stress relieving, brazing, sintering, drying, curing, and preheating.
At Maharith Thermal Pvt. Ltd., we design and manufacture custom conveyor furnaces that deliver excellent temperature uniformity, reliable operation, and high production efficiency for a wide range of industrial applications.
How does a conveyor furnace work?
A conveyor furnace operates by automatically transporting components through multiple temperature-controlled zones using a conveyor system. The components enter one end of the furnace, move through preheating, heating, soaking, and cooling sections, and exit after completing the required process cycle.
The conveyor speed is controlled using a variable speed drive (VFD), ensuring each component receives the correct heating and soaking time. Advanced PLC-based controls, multi-zone heating, and optional protective atmosphere systems provide consistent product quality and repeatable heat treatment results.
At Maharith Thermal Pvt. Ltd., our conveyor furnaces are engineered for continuous, automated production with precise temperature control and reliable long-term performance.
