After "China on the Tip of the Tongue" was broadcast on 20 18, Zhangqiu wok instantly became an online celebrity wok, and many people wanted to buy the real Zhangqiu wok, which was really hard to find at that time. The reason is that the production process of Zhangqiu iron pot is very complicated. It is an iron pan made of a whole piece of iron through 12 procedures, 18 times of heating, 1000 degrees of high temperature melting, and more than 36,000 times of hammering.
Zhangqiu, Jinan, Shandong Province is famous for smelting iron since ancient times. Moreover, it is said that every household in Zhangqiu used to strike iron. Zhangqiu's iron pots have always been made by hand, and there is no machine. This process of making iron pots has been passed down for thousands of years.
So today we will take a look at how the 12 process of Zhangqiu iron pot came about.
1 The step of making a wok is to open the iron, that is, burn a thick iron block and then burn the fat red and white. One person raises money, swings a small hammer, and then the two take turns to smash the hammer, and together they use a big hammer to repeatedly smelt iron and hammer.
Step 2, cut the material, draw the outline of the pot on the punched iron plate, and then cut the iron plate with iron tongs.
The third step is to make a pot handle. The most authentic technology should be to finish the handle first, burn the end of the handle red, then roll the handle with red-hot trimming into a circle, make a U-shape on the side of the tool, then close it and round it.
The fourth step is to lay the foundation, which is the most important step in the process. It must be done by two people together, one with a sledgehammer and the other with a small hammer.
The fifth step is colander, which is to burn the cooked pot skin red again, and then deepen and enlarge the colander through the mold. At the same time, the edge folds of the pot should be smooth, and there should not be too many folds, otherwise it will affect the subsequent process.
Step six, bend. Many fake pot handles pressed by machines will have obvious protrusions, while real manual breaking will naturally smooth the pot behind the colander, and the handle with skin will generally face upwards. Need to burn the root of the handle red, and then hammer it at an angle.
The seventh step is rough forging, which produces a thick oxide layer on the surface of the pot blank after repeated final burning in the furnace, and then beats the surface repeatedly with a hammer to make it smooth.
Step 8, polish the pot batch, then brush it repeatedly with a wire brush to polish off the oxide layer on the surface, and carefully polish off the black copper oxide when polishing, so that the pot will become brighter.
Step 9: Cold forging: rough forging with a heavy hammer to form a hammer mark on the pot, and then forging it into a mirror surface bit by bit until the five senses of the human face can be seen in the pot.
Step 10 is rounding. After repeated forging, the pot will be deformed. At this time, the pot needs to be rounded by the mold.
Step 1 1 is trimming, and the redundant part is removed with a tool to ensure that the spout is flat.
Step 12: Fine grinding, that is, grinding the edge cut in the previous step to rest.
