Aluminum Ceramic Fiber Nozzle Cavity improves the uniformity of the melt distribution in the nozzle device by the split block inside the nozzle device, and improves the quality of the cast and rolled products.
This aluminum plate casting device includes: two upper and lower plates oppositely arranged, an edge baffle connecting the two upper and lower plates side portions, and a bottom plate connecting the two upper and lower plates and two edge baffles, and a melt is arranged in the middle of the bottom plate Inlet, the opposite side of the melt inlet is the melt outlet.
Among them, the casting nozzle device also includes a primary shunt unit and a secondary shunt unit sandwiched between two upper and lower plates. The distance from the primary shunt unit to the base plate is greater than the distance from the secondary shunt unit to the base plate.
The primary shunt unit includes several primary shunt blocks with a rectangular cross-sectional shape and spaced apart from each other, the secondary shunt unit includes several secondary shunt blocks with a semi-circular cross-sectional shape and spaced apart from each other There is a first-level interval between the first-level shunt blocks, and each first-level interval is set against a second-level grading block.
Aluminum Ceramic Fiber Nozzle Cavity
When a certain amount of slag has accumulated on the Aluminum Ceramic Fiber Nozzle Cavity, the slag scraper used to remove the slag on the nozzle piece is placed between the upper roll of the aluminum casting mill and the upper nozzle piece. The free end of the slag scraper piece is in contact with the nozzle piece of the upper casting nozzle, and the support piece is in contact with the upper roller. With the rotation of the upper roller, the support piece drives the slag scraper piece to move forward continuously, and the movement of the slag scraper piece can push the upper casting nozzle The slag on the mouth piece moves forward.
Then, the slag accumulated on the nozzle piece of the upper casting nozzle is removed to the aluminum plate, and at the same time, the slag scraper and the support piece also fall onto the aluminum plate. Although this part of the aluminum plate is damaged by the slag, scraping slag and support sheet, it can ensure that the subsequent aluminum plate will not be defective due to the influence of the slag.
Therefore, the slag accumulated on the nozzle piece of the casting nozzle can be removed under the condition of little influence on the production efficiency.
