AAC Block Panel Autoclave: Core Equipment for AAC Block Production Line & ALC Panel Production Line
The AAC block panel autoclave is the indispensable core high-pressure curing equipment matched with AAC block production line and AAC panel production line. It provides stable temperature and pressure conditions to complete the hydrothermal reaction of AAC green blocks, ensuring high strength, stable density and excellent performance of finished AAC blocks, ALC wall panels and precast wall materials.
This article covers the working principle, classification, technical parameters, advantages, installation and maintenance of autoclave supporting for full set AAC production line and ALC panel production line, helping you select supporting curing equipment for your AAC factory project.
1. What is an AAC Block Panel Autoclave?
An AAC autoclave is a horizontal pressure vessel specially supporting the steam curing process of aerated concrete products in AAC block production line and ALC panel production line. Under high-pressure saturated steam, the calcium silicate hydrate reaction inside AAC green bodies is accelerated, transforming semi-finished products into high-strength lightweight AAC blocks and reinforced ALC panels.
It is supporting equipment for 50,000m³ to 600,000m³ annual capacity full AAC panel production line, and plays a decisive role in the overall operation of the AAC manufacturing process.
2. Working Principle of AAC Autoclave
2.1 Steam Curing Process
1. AAC green blocks are transported into the autoclave
2. The autoclave door is locked and sealed
3. High-pressure steam is injected to heat and pressurize
4. Constant temperature and pressure curing for 6–10 hours
5. Pressure release and cooling
6. Autoclave door opened for finished blocks and panels from AAC production line
2.2 Key Reaction Conditions
• Temperature: 180°C – 200°C
• Pressure: 1.0 – 1.3 MPa
• Holding time: 6 – 12 hours
• Steam source: boiler or waste heat recovery for complete AAC line
