Because of the development of science and technology and the progress of society, many people's daily indispensable skills are quietly withdrawing from the historical stage. Stainless steel kitchen stoves entered the homes of ordinary people, and the traditional "aluminum pot" gradually disappeared from the family. In the past, the shouts of pouring pots all over the street have gradually disappeared, almost out of sight.
Recently, in Du Qifeng Street Village, Suxian District, Chenzhou, we can see a couple from Anhui who are dumping aluminum pot for vendors who need large containers along the street. A pile of rotten aluminum pot antimony pots are smelted in a small stove for a few minutes, and then poured into the mold. In a blink of an eye, all kinds of brand-new aluminum pot and aluminum pot can be "inverted". This technique of "turning the old into the new" is called "toppling aluminum pot".
"Pour aluminum pot" is mainly divided into several working procedures: mold filling, aluminum melting, casting, polishing and shaping. The mold is divided into an inner membrane and an outer membrane, and the inner membrane is recessed into the shapes of various pots. There is a pouring riser at the top of the outer mold, and the gap between them is a pot, etc. The waste aluminum ladder material is crushed and put into a container, and heated on a coke fire. When heated to 660℃, aluminum will melt into liquid state; Next is casting, where molten aluminum is carefully injected into the mold from the hole. Before the solidification is completely cooled, lift the outer mold and take out the new pot. Finally, the pot is polished and shaped with pliers and a file, and a pot is made. "'
The most important thing in aluminum pot is the temperature. When the heat comes, the aluminum melts completely, and the poured aluminum pot has no sand holes and is durable! Masters said: "aluminum pot" is not only a physical activity, but also a technical activity. The temperature of molten aluminum depends entirely on the naked eye. You have to be careful when casting. A little carelessness may lead to waste products, which depends on technology and experience. Turn around the stove every day, sift sand, turn over the mold and polish it, and it will be a hard struggle at the end of the day.
It used to be a very grounded folk craft. In recent years, with the improvement of people's living standards, aluminum cookware has been gradually replaced by stainless steel products, and street craftsmen who have fallen to aluminum pot are rarely seen. Anhui's master said: We drive agricultural vehicles to Du Qifeng once or twice a year. After all, counties and villages still need these aluminum pot which are lighter, less damaged and durable than iron pots.
