Skirt Cooling Bed in Hot Rolling Mill

Skirt Cooling Bed in Hot Rolling Mill

1. Operating Principle:

The skirt cooling bed is a key auxiliary equipment in the hot rolling mill, primarily used for the cooling and stabilization of metal sheets after hot rolling. The main operating principle involves conveying the hot-rolled metal sheets from the rolling mill to the cooling area using a conveyor belt. In this area, a series of cooling devices, such as water spray nozzles or tanks, rapidly cool the metal sheets to reduce their temperature. After cooling, the sheets are conveyed to the next processing stage or into storage.

2. Structural Components:

Conveyor System: The core component of the skirt cooling bed is the conveyor system, designed to transport metal sheets stably. These conveyors are typically made of high-strength materials to withstand high temperatures and heavy loads.

Cooling Devices: The cooling devices include multiple water spray heads or tanks, employing methods such as water spraying or immersion to rapidly cool the metal sheets. This helps control the temperature of the sheets, ensuring they attain the desired mechanical properties.

Supporting Structure: To ensure the stability and reliability of the cooling bed, it includes a robust supporting structure, often constructed from steel or other high-strength materials.

3. Features and Advantages:

Rapid Cooling: The skirt cooling bed facilitates fast cooling of hot-rolled sheets within a short time, ensuring they achieve the required hardness and strength.

Automation Control: Modern skirt cooling beds are equipped with advanced automation control systems that monitor sheet temperatures in real-time and adjust the cooling process to meet the requirements of different materials and specifications.

Efficient Operation: The efficient operation of the skirt cooling bed contributes to increased production capacity for the entire hot rolling production line, reducing sheet production cycles.

4. Applications:

The skirt cooling bed is widely used in the production of various metal sheets, including steel and aluminum sheets. Its primary purpose is to adjust the sheet's microstructure through rapid cooling, thereby enhancing the mechanical properties of the product.

5. Development Trends:

With technological advancements, skirt cooling beds are evolving towards smart, efficient, and environmentally friendly solutions. The application of new cooling technologies and materials is expected to further enhance the performance of skirt cooling beds to meet the changing demands of the market.

The skirt cooling bed plays a crucial role in ensuring product quality and improving production efficiency within the hot rolling mill production line.
