Description

Technical Field

[0001] This utility model relates to the field of high-chromium cast iron roll production technology, specifically a cooling device for high-chromium cast iron roll production. Background Technology

[0002] High-chromium cast iron rolls are important components widely used in the steel rolling industry, renowned for their excellent wear resistance, resistance to thermal cracking, and resistance to thermal fatigue. They are primarily made of high-chromium white cast iron, and through specific casting and heat treatment processes, they acquire unique microstructure and performance characteristics. High-chromium cast iron rolls are widely used as support rolls and work rolls in hot-rolled strip, section steel, bar, and wire rod mills.

[0003] Currently, during the production and processing of rolls, it is necessary to cool the heated and formed rolls, which requires the use of cooling devices. However, existing cooling devices for chromium cast iron rolls cannot effectively move the rolls during use, thus preventing them from fully contacting the cold air and water, resulting in insufficient cooling and reduced cooling and utilization efficiency. Furthermore, they cannot effectively drive the water flow, preventing the water flow from slowly and orderly cooling the rolls, further reducing their working efficiency. Therefore, we propose a cooling device for high-chromium cast iron roll production.

[0004] To address the above problems, this utility model provides a cooling device for the production of high-chromium cast iron rolls, which enables effective movement of the rolls, allowing them to fully contact with cold air and water, thereby achieving sufficient cooling and improving cooling efficiency and utilization efficiency.

Example

[0019] Please see Figure 1-5 A cooling device for the production of high-chromium cast iron rolls, wherein the top of the two right-side L-shaped plates 19 are connected to side plates 7, and a cooler 8 is connected between the two side plates 7. The air outlet on the left side of the cooler 8 is fitted with a guide pipe 9, and the left end of the guide pipe 9 is connected to a three-way pipe 10. The front and rear sides of the three-way pipe 10 are respectively connected to U-shaped pipes 17, and a hollow cooling pipe 18 is connected between the two U-shaped pipes 17. The inner wall of the hollow cooling pipe 18 is provided with several evenly distributed air jet holes 20.

The aeration pump 3 aerates through the aeration pipe 24 and aeration hole 25, which drives the water flow to surge effectively, thereby allowing the water flow to cool the roll slowly and orderly, improving its working efficiency.
