When Casting Low Carbon Steel Under Certain Mold Conditions

ME215 Common exam 2 review Flashcards | Quizlet

The differentiation between plain-carbon and alloy steels is arbitrary since both contain carbon, manganese, and usually silicon. Copper and Boron are possible additions to both classes. But steels containing more than 1.65% manganese, 0.60% silicon, or 0.60% copper are usually designated as alloy steels.

Metal Casting Design: Life of a Casting | Reliance Foundry

Good metal casting design means creating the simplest mold that will produce a desired shape. This process requires expert knowledge of metals and casting methods to find the best value in a quality casting. End-users often need to know how a cast metal object will behave when struck, in different heat conditions—and most importantly, under load.

Low Pressure Casting - an overview | ScienceDirect Topics

In low pressure casting, the mold is located above the sprue and metal flows ‘up’ the sprue and into the runner system and the casting cavity(s), (Fig. 7.9).The metal flow for the arrangement shown in Fig. 7.9 is accomplished by pressurizing the furnace, which is located below the mold. The rate of metal flow is controlled by the rate of pressurization of the furnace.
