Why do you need to add crystalline silica aluminum to a pouring aluminum pan

Because that can be better fixed and molded. Pouring aluminum pot mold belongs to an ancient Chinese traditional handicraft technology, we used to see these "pouring pot people" in the streets and lanes in the yelling voice, their general practice is to put some of our traditional aluminum products, such as scrap aluminum pots, aluminum pots, cans, aluminum wire and so on a variety of waste aluminum products recycling melt, and then according to a fixed cement mold to make a new aluminum product of a fixed shape or size. Afterwards, they follow a fixed cement mold to make a new aluminum product of a fixed shape or size.

Because of the development of science and technology and the progress of society, many people from the past usually day indispensable craft skills are quietly out of the stage of history. Stainless steel kitchen stoves into the homes of ordinary people, the traditional "aluminum pot" gradually disappeared from the family, the past street pouring pot yell gradually disappeared, it is difficult to see.

In recent times, in Chenzhou Su Xian District, Qifengdu street countryside, see a couple from Anhui Province, along the street for the need for large containers of vendors folks pouring aluminum pots. A pile of rotten aluminum pots antimony pots in a small furnace melting a few minutes, poured into the mold, the blink of an eye will be able to "pour" a variety of brand new aluminum pots, aluminum pots, this "old into a new" skill is called "pouring aluminum pots "

This is the first time I've ever seen an aluminum pot in my life.

"Pour aluminum pot" is mainly divided into the installation of molds, molten aluminum, casting, grinding and shaping several processes. The mold is divided into inner and outer membrane, the inner membrane concave for the shape of various pots, the top of the outer mold has a pouring risers, naked buckle the inner mold, the gap between them is a pot, etc., scrap aluminum ladder material knocked flat on the container, heated on the coke fire, when heated to 660 ° C, the aluminum will be melted into a liquid state; followed by the casting, will be carefully injected into the mold from the holes of the aluminum water, while the solidification of its not completely cooled down, the outer mold will be lifted open , removing the new pot, and finally the shaping is done by grinding and shaping with pliers and files, and a pot is ready. "'

Pouring aluminum pot 'fire is the most important, the fire to, the aluminum melted thoroughly, pour out of the aluminum pot without sand holes, strong and durable!" Masters said: "pouring aluminum pot" is both physical and technical work, aluminum water temperature is high and low, all with the naked eye to identify the color recognition, casting to be careful, a little carelessness may be scrap, and this is relying on technology and experience. Every day around the furnace, sieve sand, turn the mold, grinding processing, a day down the fight is physical strength.

In the past is a very grounded folk craft work, in recent years, with the improvement of people's living standards, aluminum cookware is gradually replaced by stainless steel products, "pouring aluminum pots and pans," the street craftsmen rarely seen. Anhui master said: Qifengdu we drive a farm car once or twice a year, after all, the county countryside still need these lighter than iron pots and pans, not easily damaged, durable aluminum pots and pans ah.
