Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a novel water retaining plate for a cleaning section of a high-speed continuous annealing production line for cold-rolled tinplate. Background Art

[0002] Water baffles are designed and installed at the roll necks of the cleaning section to protect against splashes of alkali liquid during high-speed strip steel production. Due to the thinness of the strip steel and the high speeds of the production line, the splashing alkali liquid erodes the water baffles over time, causing them to gradually harden and eventually fall off and fail, resulting in leakage. This increases energy consumption and production costs, severely impacting the environment and posing a potential environmental risk. The splashing alkali liquid also corrodes the bearing seats, damaging the bearings, leading to roll failure and unit downtime.

[0003] The prior art discloses a water retaining ring, the area of which is greater than that of the main transmission connecting shaft sleeve, and the edge of the water retaining ring is inclined toward one end of the roller body. By providing a water retaining ring on the working roller and providing a water collecting trough and a drainage hole on the water retaining ring, the coolant during processing can be effectively prevented from entering the connecting shaft sleeve through the matching gap between the roller head and the main transmission connecting shaft sleeve, and the coolant can be redirected to the roller body for re-spraying through the drainage hole, thereby effectively improving the cooling effect of the roller body.

[0004] The above technical solution shields the roll neck and roll body through a water retaining ring. However, the high-speed rotation of the roll body causes the coolant to splash, resulting in poor shielding effect of the water retaining ring on the roll neck and roll body. The roll neck and roll body will still be corroded and damaged, which requires further improvement. Utility Model Content
