Abstract

The method of position-fix and size of "deadman" is developed in the furnace of high furnace. By means of the offered technique of definition of a site and the rough size "deadman", there was a possibility to estimate its influence on work of a heart of a blast furnace. The conducted researches on a blast furnace of № 1 PSJ "АМC" have shown that a hearth work appreciably depends on a site and the size of the "deadman". On the basis of the data about influence of the "deadman" on a drainage of products it was offered to organize a mode of releases so that not to create stagnant zones in the hearth. For a blast furnace of № 1 PSJ "AMC" it is recommended will use a mode release in which every second release to be made through removed from others notch, and the others of release are made serially on others notches.
