Influce Mechanism on Compressive Strength of Coke in Blast Furnace

Abstract:

Coke is the unique role of supporting material column in blast furnace high temperature region. Therefore the most important property is the high temperature compressive strength after reaction. This paper used decarburization electric furnace, electric mirrors, adjustable atmosphere high temperature compression testing machine and other equipments, study on the relationships between coke carbon loss rate and reactivity and size, the distribution rule between high temperature compressive strength and coke carbon loss rate. The study found that the carbon loss rate was affected by reactivity and size, in the same piece of coke, external rate of carbon loss higher than the internal loss, the surface carbon losses affect on coke strength is less, it make coke size decrease; carbon losses occur inside will not affect the size of coke, but it may affect the coke compressive strength seriously. The compressive strength can be divided into two parts: a constant and an amount proportional to carbon loss rate.
