Comparison between Two Type Mesh Belt Carburizing Quenching Furnace-2

III. Economy and Applicability

Initial Investment and Operating Costs

Muffle-Free Furnace: It has a simple structure and low initial investment, but high gas consumption leads to higher long-term operating costs.

Muffled Furnace: It has a high initial investment (due to the muffle can and sealing design), but low gas consumption results in lower long-term operating costs.

Applicable Scenarios

Muffle-Free Furnace: It is suitable for scenarios with high production volumes, general atmosphere control requirements, and limited budgets (such as batch production of small and medium-sized parts).

Muffled Furnace: It is suitable for scenarios with high heat treatment quality requirements, strict atmosphere control, and sufficient budgets (such as production of high-precision gears and bearings).

IV. Typical Application Cases

Muffle-Free Mesh Belt Furnace

Application: Carburizing and quenching of automotive components (such as drive chains and self-tapping screws).

Advantages: High automation and production efficiency, suitable for large-scale continuous production.

Muffled Mesh Belt Furnace

Application: Heat treatment of aerospace parts and precision molds.

Advantages: Precise atmosphere control, stable heat treatment quality, and reduced oxidation and decarburization.

V. Comprehensive Evaluation and Recommendations

Scenarios Recommended for Muffle-Free Furnaces:

Limited budget and need for rapid commissioning;

High production volumes with general atmosphere control requirements;

Less stringent requirements for workpiece deformation.

Scenarios Recommended for Muffled Furnaces:

High heat treatment quality requirements and strict atmosphere control;

Production of high-value-added parts (such as aviation bearings and precision gears);

Long-term operation with a need to reduce comprehensive costs.
