The box type annealing atmosphere furnace plays a critical role in mold manufacturing by enabling precise heat treatment processes that enhance material properties. It performs spheroidizing annealing on mold steels like Cr12MoV, heating them to 780°C–800°C, holding for 2–4 hours, and slowly cooling to below 500°C before air cooling. This process spheroidizes carbides, reduces hardness, improves machinability, and prepares the microstructure for subsequent processing. The furnace ensures uniform temperature distribution via strategically placed heating elements and real-time temperature control, while safety features and atmosphere control further optimize efficiency and material outcomes.
Key Points Explained:
-
Spheroidizing Annealing for Mold Steel
- The furnace treats mold steels (e.g., Cr12MoV) by heating to 780°C–800°C, holding, and slow cooling.
- This transforms carbides into spherical shapes, reducing hardness and improving cutting performance.
- Prepares the material for final heat treatment, enhancing mold precision and longevity.
-
Uniform Heating and Temperature Control
- Heating elements (arranged around, at the bottom, or top) ensure even heat distribution via radiation and convection.
- A batch atmosphere furnace uses sensors and automated power adjustments to maintain precise temperature ranges, critical for consistent results.
-
Versatility in Material Treatment
- Beyond mold steel, the furnace anneals or brazes metals like titanium alloys and stainless steel.
- Controlled atmosphere (e.g., inert gas) prevents oxidation and achieves desired material properties.
-
Energy Efficiency and Safety
- Thermal homogeneity and accurate controls minimize energy waste, lowering operational costs.
- Safety features (overcurrent/voltage, overheating, and leakage protection) ensure process reliability.
- Sealed furnace doors prevent atmosphere leakage, maintaining treatment integrity.
-
Impact on Mold Manufacturing Workflow
- Optimizes pre-machining material conditions, reducing tool wear and improving dimensional stability.
- Ensures repeatability, which is vital for high-volume or precision mold production.
By integrating these functions, the furnace bridges material science and manufacturing efficiency, quietly underpinning the durability and performance of molds used across industries.
