Explain at least three control features/aspects of the continuous casting process of steel that are used to limit steel exposure to the air and promote inclusion removal. Consider (where applicable) how each part of the continuous casting process is designed to accomplish this.

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
