Abstract

The bachelor thesis is divided into five main chapters dedicated to the production of pig iron, the blast furnace construction, refractory materials which are used for walling of the blast furnace, their location in the blast furnace and parts to the end of cooling blast furnace brickwork. The first chapter describes the historical development of the production of pig iron from the first mentions of pig iron production to today. It also contains a subchapter devices associated with the production of pig iron and the description of the production of pig iron. The second chapter deals with the construction of a blast furnace, its foundations, supporting steel structure and description of the furnace from which it is composed. The third chapter provides an overview of basic refractory materials used in the lining of the blast furnace. It is the chemical composition, the basic properties of refractory material and a description of selected refractory materials. Penultimate, the fourth chapter deals with the construction of the lining of the blast furnace, where they are mentioned causes wear linings and the actual use of certain refractory material in different parts of the blast furnace. An important part of the long life of the lining is its cooling, which is also described a system and structure cooling elements and their location at the blast furnace.
