Annealing furnace annealing is a metal heat treatment process that refers to slowly heating the metal to an appropriate temperature, maintaining it for a sufficient time, and then cooling it at an appropriate rate, sometimes natural cooling, and sometimes controlled rate cooling.
1. Reduce hardness, soften workpieces, and improve machinability.
2. Improve or eliminate various structural defects and residual stresses caused by steel during casting, forging, rolling, and welding processes, reducing workpiece deformation, cracking, or cracking tendency.
3. Refine the grain size, improve the structure to enhance the mechanical properties of the workpiece, and eliminate structural defects.
4. Uniform material structure and composition, improving material properties or preparing the structure for future heat treatments such as annealing and tempering.
After inspection, if a leak is found, it needs to be promptly sealed to achieve the effect of improving the atmosphere inside the furnace. Repair welding on the cracked part of the weld seam; Old or damaged sealing gaskets need to be replaced; Strengthen the bolts that drive the wheels.
The atmosphere inside the annealing furnace is crucial for the surface quality of the product, and establishing a furnace airtightness inspection system can ensure timely detection of leakage problems. The regular standards and calibration of online monitoring instruments can ensure the provision of correct measurement data guidance for production, combined with the correct leakage inspection and handling methods, which play a crucial role in improving the atmosphere inside the furnace.
