Comparison Between Online Annealing Furnaces and Offline Annealing Furnaces-2
Nov. 22, 2025
Three. Comparison of the actual application scenarios of classification
Scene | Online annealing furnace | Offline annealing furnace |
Steel industry | Continuous annealing production line (such as annealing of cold-rolled plates) | Car-type annealing furnace (such as for annealing large castings) |
Processing of non-ferrous metals | Copper wire online annealing machine | Pit type annealing furnace (such as for annealing aluminum profiles) |
Automobile manufacturing | Spring steel wire online annealing equipment | Spherical annealing furnace (such as for tempering after gear quenching) |
Electronics industry | Precision Strip Continuous Bright Annealing Furnace | Vacuum annealing furnace (such as for annealing semiconductor materials) |
Small batch production | Not applicable (requires continuous production) | Flexible and applicable (capable of handling individual items or small batches) |
Four. Summary of the Advantages and Disadvantages of Classification
Type | Advantage | Disadvantage |
Online annealing furnace | 1. High production efficiency, suitable for large-scale continuous production; 2. High energy utilization rate, energy-saving and environmentally friendly; 3. High degree of automation, reducing labor costs. | 1. The equipment has a high cost. 2. It requires high integration of the production line. 3. The flexibility is low and it is difficult to adapt to multi-variety production. |
Offline annealing furnace | 1. The equipment has a low cost. 2. It is highly flexible and suitable for multi-variety and small-batch production. 3. It is easy to maintain and does not affect the operation of the production line. | 1. Low production efficiency, intermittent processing; 2. Possible low energy utilization rate; 3. A lot of manual intervention, high labor intensity. |
