1. Difference 1: Pig iron pots are iron alloys with a carbon content of 2~6.69%, while wrought iron contains less than 0.02% carbon. Pig iron is also called "cast iron". In addition to carbon, it also contains silicon, a small amount of sulfur and phosphorus.

Etc., it is castable but not malleable, just the opposite of wrought iron.

2. Area 2: Wrought iron pot is pure iron refined from pig iron, with a carbon content of less than 0.02%. Compared with pig iron pot, it contains less carbon. Wrought iron is also called "wrought iron, pure iron", pure iron.

Iron requires low content of impurity elements such as carbon, phosphorus, and sulfur. Its smelting is difficult and its manufacturing cost is much higher than that of pig iron and steel.

3. Difference 3: Wrought iron is very soft, has good ductility, is easy to deform, is strong and has low hardness, while pig iron pots are harder. On the contrary, wrought iron is easy to forge and weld, but is not widely used. Pure iron is used as an electrical material.

It has high magnetic permeability, is used in various iron cores, and is also used as a raw material for high-grade alloy steel. Pure iron is rarely used as a structural material. Because of its soft texture, its strength is not high.

4. Difference 4: Pig iron pots contain a lot of carbon, are wear-resistant and castable, but are hard and brittle and cannot be forged. Wrought iron can be forged and welded. According to the difference in carbon, it is divided into: steelmaking pig iron, casting pig iron, etc.

kind.

Tips for using iron pots: 1. (Boiling the pot with water is helpful for sterilization and sterilization) Put the pot on the fire, pour an appropriate amount of water, turn up the heat and bring to a boil, cook for about 10 minutes and turn off the heat.

2. (Saline frying pan is helpful to remove odor and prevent rust) Put 1 spoon of salt in the pot, heat it over low heat, and stir-fry the salt continuously with a shovel.

3. (Ginger is good for removing odor) Put a piece of ginger into the pot, press the ginger slice with chopsticks, and wipe it back and forth in the pot for 3 to 5 minutes, so that every part of the inner wall of the pot needs to be wiped evenly.
