Boquilla de fundici\u00f3n de alimentador<\/strong> is a key component of the aluminum strip continuous casting and rolling mill, and its quality directly affects the quality of the strip and the yield of production.
\nIt includes a feed port with a narrow rear end and a feed port with a wider front end. In the material passage between the feed port and the discharge port, a partition block divides the material passage into two side-by-side parts.<\/p>\n

The liquid impurities in the aluminum alloy melt that contact the surface of the casting nozzle precipitate and solidify with the decrease of temperature, resulting in an increase in the surface roughness of the casting nozzle and causing slagging of the casting nozzle.
\nAt high temperatures, the aluminum melt is in contact with the SiO2 particles in the nozzle material for a long time, and Al2O3 particles are formed on the surface of the nozzle, which aggravates the occurrence of nozzle blockage.
\nThe molten aluminum is easy to solidify on the uneven surface of the nozzle, and the cavity of the nozzle gradually becomes narrow, which eventually causes the nozzle to block.
\nA three-layer structure is formed in the blocked nozzle cavity, a reaction layer, a slag layer and a metal layer are distributed.<\/p>\n

Feed Casting Nozzle internal fluid<\/strong>
\nNear the center of the cavity, the flow rate is fast and the flow is relatively stable.
\nNear the wall of the cavity, the flow rate is slow and steady.
\nIn the middle part, the flow rate is moderate but the flow state is complex and changeable.<\/p>\n

The casting speed, the width of the casting plate and the surface roughness of the nozzle cavity<\/a> have a significant influence on the flow of the melt in the nozzle cavity.
\nCon el aumento continuo de la velocidad de colada, el estado turbulento del flujo de metal fundido en la cavidad tambi\u00e9n se vuelve m\u00e1s complejo.
\nA medida que aumenta la anchura de colada, se acent\u00faa la diferencia de velocidad entre el borde de la salida de la boquilla y el centro de la salida.
\nCon el aumento continuo de la rugosidad superficial de la cavidad de la tobera, el flujo liso en la zona pr\u00f3xima a la pared se interrumpe y da paso a una turbulencia compleja, lo que agrava el fen\u00f3meno de la formaci\u00f3n de escoria.<\/p>\n

Aluminum coil production process<\/strong>
\nThe aluminum ingot is put into the melting furnace, burned and melted with natural gas, slagging and waste removal, alloy configuration, guide furnace to the holding furnace, aluminum water, passing through the die nozzle, rolling cast coil, rolling cold rolled coil, annealing, cross shear To the required size, engrave according to the drawings, hemming, reinforcement, welding, polishing, spraying, inspection, sticking protective film, air cushion film, packing, loading and shipping. The performance of aluminum coil: if used for exterior wall decoration, generally use 2mm, 2.5mm, 3mm thick aluminum coil, reinforced ribs and corners can be fixed on the keel, the exterior wall decoration is firm and reliable, and the metal texture is strong. Spray weather-resistant coatings will not change or fade within 20 years, and keep the color bright.<\/p>","protected":false},"excerpt":{"rendered":"
