Cast rolling CC aluminum production process
Cast rolling aluminum sheet for bottle caps is through the aluminum ingot, smelting, casting mill rolled into a strip. Casting process compared with the hot rolling process is relatively simple, with less investment, low cost, high efficiency advantages, but like component segregation, inclusion and other defects are not easy to solve, so the quality is not as hot-rolled material.
The hot rolling is a processed structure having a heat distortion of 90% or more and is subjected to synchronous recrystallization during the hot rolling, so that the grain of the strip is fine, and each of the strip Performance is uniform. The problem is that the deep processing performance of the product (deep drawing, bending performance, etc.) casting and hot rolling method than the gap between the larger
Cast rolling temperature is generally between 680 ℃ -700 ℃, the lower the better, stable casting line generally more than a month will stop once, re-board, the production process need to strictly control the front box level, to prevent the liquid level low. Lubrication is carried out by the incomplete combustion of the C powder, which is one of the reasons why the surface of the casting material is dirty. The production speed is generally between 1.5m / min-2.5m / min. Casting production of the product surface quality is generally low, generally can not meet the special physical and chemical properties of the product.
