Subject aims expressed by acquired skills and competences

Students will be able to characterize the fundamental principles of the use of refractory and thermal - insulation materials, characterized by specific types of lining furnaces and heating equipment with regard to production technology in their ongoing and based on the design will be able to lining furnaces and equipment in metallurgy and engineering industries, kilns and furnaces in the ceramic industry, glass furnaces, kilns in the chemical industry and heat in energy. In addition, students get acquainted with the analysis of phase relationships in refractory materials due to corrosion and mechanical, chemical and thermal stresses that will be able to include in the body of knowledge in the design of structures lining. The course also introduces the technology of the production of refractory shaped and unshaped materials and repair technologies. Based on this knowledge, students will be able to not only determine the overall composition of the lining of the aggregation in terms of technological operations, but also suggest lining, which will have the greatest life in the light of the economic budget of the company.
