Cast Iron casting

Cast iron is an alloy of iron with a carbon to carbon ratio of at least 2.14%. Mostly metal is divided into 2 types: gray and white. In the first, the silicon and graphite content is from 2.9 to 3.7%.

On the main page, we have given a sequential description of the stages of work.
Here, we want you to familiarize yourself in detail with the basic methods of iron casting:

Casting in molds from a clay-sand mixture;
Gypsum, or shell form;
Metal protected form;
Under pressure;

Inside the mold itself, we place a model of the finished product, which repeats it, but is larger in size according to the amount of casting shrinkage.
The mixture is compacted and compacted so that it completely adheres to the model. Next, we carry out casting through the holes (sprues).
