Description

Technical Field

[0001] This utility model relates to the field of hot-dip aluminum-silicon coating technology, specifically a roller system suitable for aluminum-silicon pots. Background Technology

[0002] In cold-rolled galvanizing (including electro-galvanizing) and aluminizing / zinc-plating mills, the roller system is a critical piece of equipment. Its function is to redirect the strip in the molten zinc or zinc-aluminum solution so that the strip can be coated with zinc or aluminum-zinc coating. The roller system includes submerged rolls, stabilizing rolls, and straightening rolls. Each of the submerged rolls, stabilizing rolls, and straightening rolls includes roll arms, bearing housings, and rolls.

[0003] The existing aluminizing and zinc plating unit involves the following installation process for the submerged rollers, stabilizing rollers, and straightening rollers each time they are used: the bearing housing on one side is welded to the roller arm, the roller is inserted into the bearing housing, and on the other side, the roller is first inserted into the bearing housing and then welded to the roller arm. When replacing them after use, the welds are cut off and new bearing housings are reassembled. This disassembly and assembly is very inconvenient during production. Furthermore, while the existing roller system meets the production requirements of molten zinc and zinc-aluminum solutions with relatively low corrosiveness and temperatures below 500°C, the highly corrosive nature of molten aluminum means that the roller materials commonly used in zinc pots are easily corroded during use, resulting in a short service life and affecting the normal production of aluminum-silicon products. Summary of the Invention

[0004] The purpose of this invention is to provide a roller system suitable for aluminum-silicon pots, which is easy to assemble and disassemble during production, has a long service life, and can meet the normal production needs of aluminum-silicon products.

[0005] The technical solution adopted by this utility model is: a roller system for aluminum-silicon pots, including a submerged roller, a stabilizing roller, and a straightening roller, characterized in that: the submerged roller, the stabilizing roller, and the straightening roller each include a roller arm, a bearing seat assembly, and a roller; the end of the roller is mounted on the bearing seat assembly; the roller arm is bolted to the seat of the bearing seat assembly; and the surfaces of the roller arm, the bearing seat assembly, and the roller are all coated with a high-temperature resistant and corrosion-resistant coating.

[0006] Preferably, the roller arm is made of 316L material and has a zirconium oxide coating on its surface.

[0007] Preferably, the roller is made of silicon-containing cast iron and has a calcium-magnesium-based coating on its surface.

[0008] Preferably, the bearing housing assembly includes a housing body, a bushing, and a bearing shell. Specifically, the housing body is made of special low-carbon steel with good corrosion resistance and has an alumina-containing coating on its surface. The bushing is made of cobalt-based alloy steel and has a 2mm thick layer of hard alloy weld overlay on its surface. The bearing shell is made of hard alloy.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. The roller arm and the base are connected by bolts, which makes disassembly and assembly convenient and saves a lot of time and labor costs when maintaining the equipment and replacing parts.

[0011] 2. The roller arms, bearing housings, and rollers are coated with a corrosion-resistant coating, resulting in a long service life and virtually no corrosion during production, effectively ensuring the normal production of aluminum-silicon products. This treatment allows the roller system to withstand the high temperatures and strong corrosion of molten aluminum, significantly extending the equipment's lifespan in harsh molten aluminum environments.
