Abstract

This diploma thesis solves the design of blast furnace gutters, the basics of technology and blast furnaces refractory. The selected assignment is solved by laboratory tests because the blast furnace environment is very variable and this method can test the material before it is used in the installation. Blast-furnace troughs are a system of channels conducting liquid metal and slag into mobile mixers and slag pots. Gutters are stressed both thermally and mechanically. Therefore, high demands are placed on refractory materials. Due to high consumption for individual applications (tons), the ratio between quality and price of materials plays an important role. The objectives should be achieved by performing static laboratory tests. These tests include compressive and flexural strengths, water absorption, apparent porosity, true porosity, bulk density and density. Based on laboratory tests results, is proposal of the blast furnace gutter design. With steel shell, chamotte bricks and combinations of refractory concrete compositions.
