After some costs have been classified as manufacturing, they are normally further classified as direct and indirect. Materials used in the manufacturing process are either used directly or indirectly. Direct material is material that becomes part of the finished product and, therefore, significantly adds to the weight or size of the product.

Hot Tearing • Begins along inside corners of casting if thermal contraction is hindered • Occurs when an outside corner of the die is over-heated • Solidification of the corner is retarded, freezing & contraction of metal on either side applies stress, resulting in cracks to semi-solid metal 45. Hot Tearing (Cont'd.)

12.5.1.2.4 Casting and Finishing Most steel follows one of two major routes to final processing. The most common finishing method is continuous casting. In this process, a ladle with molten steel is lifted to the top of a continuous caster, where it flows into a reservoir (called a tundish) and then into the molds of the continuous casting machine.

The footing is wider than the wall, providing extra support at the base of the foundation. A T-shaped foundation is placed and allowed to cure; second, the walls are constructed; and finally, the slab is poured between the walls. In summary: T-shaped foundations are used in areas where the ground freezes. First, the footing is placed.

A brief discussion of the different types of casting processes. Image credit: Funtay/Shutterstock. Casting manufacturing is a process in which liquefied material, such as molten metal, is poured into the cavity of a specially designed mold and allowed to harden. After solidification, the workpiece is removed from the mold to undergo various finishing treatments or for use as a final …

Diagram of the continuous casting process. After solidifying, these metal strands are cut into 3- to 15-meter long pieces and left to cool. In continuous casting, the shape of the strand can be cast closer in shape to the final product than what would be produced during ingot casting, greatly reducing the cost of further processing the strands.

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.

Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace.Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.
