Description

TECHNICAL FIELD

[0001] The utility model relates to metal casting technical field, concretely relates to a casting rolling mill front box. BACKGROUND

[0002] Aluminum strip is usually produced by a casting rolling mill, and the casting rolling mill front box is an important component of the casting rolling mill. In the production process, the molten aluminum flows from a liquid supply tank into the front box, and fluctuations in the liquid level of the molten aluminum in the front box directly affect the quality of the rolled aluminum strip. Too low a liquid level can cause the molten aluminum to fail to flow smoothly into the working area of the casting rolling mill, thereby affecting the stability of the casting process. Too high a liquid level can cause the molten aluminum to overflow.

[0003] In the prior art, for example, a Chinese patent with the publication number CN219724533U and the name "Aluminum alloy casting rolling mill front box" discloses a technical solution comprising a feed pipe, a storage tank, and a discharge outlet. A filter screen is provided in the feed pipe. The aluminum alloy solution passes through the filter screen from the feed pipe into the storage tank and then flows out of the storage tank through the discharge outlet. The device reduces impurities in the aluminum alloy solution by providing a filter screen, thereby improving the quality of the aluminum alloy aluminum plate. In comparison with related technical fields and similar technical solutions, the existing mechanism usually uses a filter screen to filter impurities in the molten aluminum. However, impurities can accumulate on the filter screen during operation, causing the filter screen to be blocked. The blocked filter screen can reduce the flow of molten aluminum into the casting rolling mill front box, thereby reducing the liquid level of the molten aluminum in the casting rolling mill front box. When the liquid level of the molten aluminum is too low, the reduced liquid level pressure can cause the molten aluminum to flow poorly from the discharge outlet, thereby affecting the quality of the aluminum strip.

[0022] When the level of molten aluminum in tank 100 rises, float 240 rises along with it. Float 240, through sliding rod 230 and connecting rod 210, causes sliding support 260 to descend. Sliding support 260 then causes baffle 270 to descend, gradually blocking inlet 160 and reducing the flow rate of molten aluminum inlet 160, thus preventing overflow due to excessive molten aluminum in tank 100. When the level of molten aluminum in tank 100 falls, float 240 falls along with it. Float 240, through sliding rod 230 and connecting rod 210, causes sliding support 260 to rise. Sliding support 260 then causes baffle 270 to rise, increasing the flow rate of molten aluminum inlet 160 and preventing insufficient molten aluminum in tank 100 from hindering its flow.

[0023] When the filter screen 170 is blocked by impurities in the molten aluminum, the liquid level of the molten aluminum in the housing 100 will drop. The float 240 will fall down as the liquid level of the molten aluminum drops. The float 240 drives the sliding bracket 260 to rise through the sliding rod 230 and the connecting rod 210. The sliding bracket 260 drives the scraper 280 to rise, so that the scraper 280 can remove the impurities in the molten aluminum on the filter screen 170, thereby ensuring that the liquid inlet 160 is unobstructed.
