The first two parts of this series dealt with the use of cast iron components in refrigeration equipment. This last part will focus on the construction of such components.
In the first part of this three-part series, we talked about the effect cold shortness has on the use of cast iron in refrigeration equipment. Now we will look at porosity and abrasion resistance.
There is a large body of publications regarding uses of cast iron. But very few of them are concerned with the use of cast iron in refrigeration equipment, and even less with the behavior of such materials at low temperatures.
