How can a mesh-belt normalizing furnace be used effectively and cost-efficiently?

I. Rational Energy Selection

① Electric heating is clean and easy to control. For example, well-type resistance furnaces employ indirect heating of the workpiece, resulting in relatively low thermal efficiency; this can be improved by enhancing radiative heat transfer, reducing heat storage in the furnace lining, and minimizing heat loss through the furnace walls. In contrast, pulse ion nitriding furnaces use electricity to ionize gases at low vacuum, generating ions that are accelerated by an electric field to strike the workpiece at high velocity. While heating the workpiece, these ions also diffuse nitrogen atoms deep into its surface, yielding a heat treatment process with significantly higher thermal efficiency.

② Fuel costs are low; natural gas or town gas should be used whenever possible, as these high-calorific-value gases can form a flame in jet-type burners. Heat is transferred to the workpiece directly via thermal shock, thermal radiation, and thermal convection, resulting in a high heat-transfer coefficient and rapid heating, thereby achieving high thermal efficiency.

II. Rational Selection of Furnace Type

Once the batch size and process parameters for heat-treated products have been finalized, the selection of the furnace type becomes critical for achieving process consistency, energy efficiency, and cost reduction. Continuous furnaces consume less energy than batch furnaces, and their thermal efficiencies, from highest to lowest, are as follows: hearth-type furnaces, pit furnaces, conveyor-belt furnaces, chamber furnaces, and table-type normalizing furnaces. When the batch size is large, continuous furnaces are the preferred choice.
