Why does the tone of the iron pot become lower when there are cracks?

There are the following methods for repairing: the first one: the hole is small, pierced with a filled pot nail, the nail tail is unscrewed, and it can be evenly wiped with mud.

The second: grind it into a powder with a discarded bowl, mix it with the egg whites to form a paste, and spread the cracks evenly. The third type:

Take a small piece of pork liver, mash it, add lime powder and mix well, spread evenly on the pork liver, and heat for a few minutes. Fourth: If the hole is large, repair it with iron powder.

The powder is first boiled and melted to make molten iron, which is then poured over the holes in the pan. Under the piercing, a damp cloth is laid and the molten iron is cooled to fill the hole. When it's done, turn the pot red and flatten it with a hammer.

Extended Information: An iron pot is a traditional cooking utensil that is usually free of toxins but oxidizes when exposed to water. The main varieties of iron pans are printing pans, ear pans, pans, frying pans, pancake pans, etc.

The main component is iron, but it also contains small amounts of sulfur, phosphorus, manganese, silicon, carbon, etc. Difference Between Cast Iron Pot and Cast Iron Pot: Cast iron pot is cast from a mold that melts gray iron.

The cooked iron pot is made by a black iron sheet forging press or by hand beating, and has the characteristics of thin blank and fast heat transfer. Some people call iron supplements, but there are no experiments that suggest that iron supplements can be used in cooking. Nutritionists say that for people with hemochromatosis, it is better not to cook in an iron pot.

There are cracks in the iron pot, and the cracks will become longer with continuous exertion and longer use time.

According to the principle of acoustic resonance in physics, the longer the crack, the lower the resonant tone.

If there is a crack in the iron pot, the sound cannot be resonated, and the tone will change.

1. The induction cooker cannot use a pig iron pot with large thermal stress.

2. The uniformity of the pot body should be less than millimeters.

3. The thickness of the pot body of the induction cooker should be more than millimeters after using the induction cooker for a long time.

The working principle of the induction cooker is: the rapid change of magnetic flux generated by the induction cooker causes eddy currents to be generated inside the metal cooker.

version, and then the heat right.

After all, it is not used to conduct heat with fire, and the induction cooker is destroyed, and it will be replaced in 3 or 4 months at home.

Thermal conductivity is related to the following 3 factors.

The material of the pot. The thickness of the bottom of the pot.

The diameter of the bottom of the pot.

If the thickness and diameter are the same.

Cast iron is not as good as stainless steel.

The pot used for the induction cooker must be a special pot, and it is suspected that the quality of the iron pot you use is problematic, and the cracks are generally caused by uneven heating, and if the bottom of the pot is thin and thick, it is easy to be heated unevenly.

Why doesn't this happen in my family?

Because the pot is made at high temperatures, there may not be cracks at that time, but it is heated and cold. After the pot is left in the air for a period of time, it will shrink sharply and crack. After use, the pot returns to its original temperature, so it expands again. The crack is gone!

There is a problem with the quality of the iron pot, or the pot is too big, and it is easy to have cracks if it is heated unevenly.

If there is a crack in the furnace, it must be a problem with the quality, or if it is used for too long, the life will be damaged.

The pig iron pot on the liquefied gas stove cracked, and the fire was too hard.

It should be a quality issue. It's better to change to another one.

The stainless steel pot used on the induction cooker has a crack at the bottom, and you can go to the pot repair department to repair it, but the repaired pot will not take long, so it is recommended to buy a new one.

If the pot is leaking, it is recommended that you change the pot, if it does not leak, there will be no problem, your pot should be used for stir-frying, because the pot is leaking, it is easier to burn red at the cracks, it is easy to burn, it will be deformed, the cracks will get bigger and bigger, and the more it leaks, the more it leaks.

It can be welded with CO2 gas shielded welding and then sanded. But it doesn't cost much to buy a new one.

Before the reform came and opened up, there were people everywhere in the urban and rural areas who walked through the streets and alleys to repair the iron pot, and they used the smelted molten iron to repair the pot nails. There are cracks in the iron pot at home, as long as it is not a leak but only a leak, it can be repaired. Throw the glutinous rice into this pot and boil the rice into a rice soup with a fire, which is thick and sticky.

Place the pot on a wooden rack and wait for it to cool. Once cooled, pour out the rice cereal and set aside. Then heat the iron pot over low heat, and then place the pot on a wooden rack when the rice paper is lifted in the pot.

The pouring temperature of molten iron is too low, forming a cold barrier. You can try it by increasing the pouring temperature.

This is because if the iron pot is generally sensational, it will make a noise.

Why do you want the iron pot to break? Is it the sound of the wind?

These are all sounds of collision and friction.

Sure, isn't it all going to be like that? Isn't that what it means?

When they bump into each other, you'll think about it later, pots and pans.

It's normal to have a sound when you knock together.

When you touch it, he thinks, "Ah, this is normal, because the sound is transmitted, and it rings in the ears."

The iron pot broke the scoop, thinking that it was because you bumped into them together, so they were.

How to buy a casserole Casserole stew has a unique flavor, and the casserole decoction does not change the original taste, so the casserole is a daily consumer product loved by the majority of consumer sounds. How to choose a casserole? 1 Look at the ceramic.

The clay used in a good casserole is very fine and the color is mostly white, and the quality of the surface glaze is also very high, with uniform brightness and good thermal conductivity. 2 Look at the structure. A good casserole has a reasonable structure, is placed flat, the pot body is round, the inner wall is smooth, there are no protruding sand grains, and the lid is tight and does not change shape.

3 When purchasing, fill the casserole with enough water and check whether there is any leakage. You can also use your hands to gently tap the pot to see if the sound is crisp, if there is a hoarse sound, it means that the casserole has cracks, it is best not to buy. 4 Buy a casserole as needed.

Generally speaking, decoction does not need a casserole with good clay, and you can buy a cheap casserole without leakage. The pot for stewed food is more demanding, and it is best to choose a white casserole. How to maintain a casserole Casserole is a pottery product made of a variety of raw materials such as quartz, feldspar, clay, etc., which is smelted at high temperature to form a glass body.

This vitreous is less resilient to temperature differences. Sudden exposure to heat and cold in a casserole can cause a sharp expansion or contraction, causing it to break. In view of the characteristics of the casserole, the following aspects must be paid attention to when using:

1 Heat it gradually, and don't burn it on a fire so that it doesn't burst. 2 After the food is cooked, when the casserole is removed from the heat, use wood chips to set up the pot so that it dissipates heat evenly and cools slowly to avoid shrinkage. You can also make an iron ring according to the size of the casserole, when the casserole is off the fire, put it on the iron ring, so that the bottom of it does not directly touch the ground, and the suspension will naturally cool down, which can make the casserole use longer.

3 Newly purchased casseroles often leak because there are many trachomas. When the new pot is used for the first time, it is best to make noodle soup or gruel, after eating, do not brush the pot first, put it on the stove and bake it, so that the batter in the pot is dry and knotted, block those tiny sand holes on the wall of the pot, and then wash it. This way, the casserole won't leak.
