Sand Cooling Roll Technical Parameters
Introduction:
Sand cooling rolls are a type of faster-cooling equipment designed to rapidly cool hot products. The product is cooled quickly by passing it through one or more rolls cooled with sand, with the rolls typically filled with 10-20 tons of sand. The sand is cooled by circulating chilled water through the sand-filled rolls and is continuously removed and replenished to maintain its cooling efficiency. Sand cooling rolls are commonly used in hot rolling mills, but can also be used for other applications.
Technology Parameters of Sand Cooling Roll:
1. Width: The maximum width of the roll is determined by the width of the product to be cooled and the type of product being rolled. Most sand cooling rolls are available in widths from 1 M to 5 M.
2. Roll diameter: The diameter of the roll is determined by the product to be cooled and the capacity of the product. Most rolls have a diameter of 0.5 M to 1 M.
3. Roll speed: The speed at which the roll rotates is determined by the type of product being cooled. Most rolls can spin at speeds up to 10 m/s.
4. Number of rolls: The number of rolls used depends on the product to be cooled and the capacity of the product. One roll is typically used for small products and multiple rolls are used for larger products.
5. Sand flow rate: The sand flow rate is determined by the type of product being cooled and the cooling rate required. Generally a sand flow rate of 1 ton per hour is used for products that require rapid cooling.
6. Chilled water flow rate: The chilled water flow rate is determined by the temperature of the product to be cooled and the amount of cooling desired. Generally, a chilled water flow rate of 0.5 GPM is used.
Conclusion:
Sand cooling rolls are an efficient way to cool hot products quickly. The parameters that determine the efficiency of the sand cooling roll are the product and capacity of the product being cooled, the width and diameter of the roll, the speed at which the roll rotates, the number of rolls used, the sand flow rate and the chilled water flow rate. By choosing the correct parameters, a sand cooling roll can be an effective tool in a manufacturing process.
