cast ironCast iron was an iron with a high carbon content. It was brittle and could not be forged. It was mainly used for steel making or casting. It was a general term for an alloy composed of iron, carbon, and silicon. Its carbon content exceeded the amount that could be retained in the solid solution at the eutectoid temperature.
According to the provisions of the "Cast Iron Grade Denomination Method" of the National Code for Casting Iron, there were relevant rules for the name, code, and grade representation of cast iron. According to the different forms of carbon in cast iron, it could be divided into white cast iron, gray cast iron, and mottled cast iron; gray cast iron could be divided into ordinary gray cast iron, vermicular black cast iron, spherical black cast iron, and malleable cast iron according to the different forms of carbon.
The pig iron pot was a cast iron pot. It was hard and non-malleable. It was cast from molten iron. The pot body was thick and suitable for a family kitchen with a low fire. When using it, it needed to be heated evenly and moistened. After pouring out the oil, the empty pot was burned to form an oil film.
It was more difficult to welding cast iron. Some experienced welders had developed a method to apply grease on the welding rod. The current for welding thick cast iron parts should be adjusted to at least 200 and above. The current for thinner parts should not be lower than 180. The higher the current, the better the welding effect.

In addition, adjust the pH. Increase the pH. When mixing, add 1% - 3% quicklime or spray 2% lime water to suppress the growth of green mold.
- In the aspect of preventing and controlling the fungus, the mechanism of action of the fungus was to kill the pathogenic fungus through repeated parasitism, nutrient competition, and the action of lyase. The fungus could be used. The common dosage forms were 150 million live spores/g, 200 million live spores/g wet powder, 100 million live spores/g, and 200 million live spores/g water dispersing granules.
