Description

Technical Field

[0001] The utility model belongs to the technical field of casting and rolling equipment, in particular to a graphite spraying device used for aluminum casting and rolling production. Background Art

[0002] Aluminum foil casting and rolling mill is used to roll aluminum liquid into aluminum plates. During the processing, roll sticking is a common surface defect in aluminum plate casting and rolling. To prevent roll sticking, the usual practice is to use coal gas or natural gas as fuel, and use a flame spray gun to perform incomplete combustion on the roll surface, so that a layer of carbon powder with lubricating effect is sprayed on the roll surface. The carbon powder can separate the aluminum liquid from the roll and avoid the occurrence of roll sticking.

[0003] The upper and lower rolls of the rolling mill each have a set of double spray gun reciprocating motion mechanisms, which drive the spray guns to reciprocate at a suitable speed. During normal operation, the reciprocating speed and stroke of the spray guns are reasonably determined based on the rolling speed, plate width and other conditions, so that the carbide coating can evenly cover the entire working surface of the roll.

[0004] At present, the industry can effectively form a carbide isolation layer on the surface of the roller by flame spraying to avoid the adhesion of molten aluminum on the roller. However, this method is only suitable for low-speed rolling conditions. For high-component alloy products and high-speed conditions, this method cannot effectively form a carbide isolation layer on the roller surface. By directly spraying carbon toner, this method makes the carbide isolation layer formed on the roller surface more uniform and efficient.

[0005] In the existing roller flame spraying equipment, an air intake pipe is connected to the nozzle. The air intake pipe moves horizontally accordingly with the reciprocating horizontal movement of the nozzle. Since the air intake pipe lacks effective limit, its position cannot be effectively limited during the movement, resulting in the air intake pipe moving in an undirected manner. At the same time, during the high-temperature rolling process, the high temperature environment will also affect the life of the air intake pipe. Utility Model Content
