Abstract

See full text

A method for measuring the softening and melting performances of iron ore in blast furnace is disclosed, which is implemented by a device including a high temperature furnace, gas supply system, a loading system and a weighing system. The method includes: step 1: the dried coke and iron ore specimen are placed in the graphite crucible in a specified way; step 2: the graphite crucible is placed in the high temperature furnace, and N2 is continuously fed into the high temperature furnace to reach an airtightness requirement; step 3: a vacuum pump is used to extract mixed gas in a hearth of the high temperature furnace and heating process is started; step 4: both the composition of mixed gas and pressure imposed on the iron ore are controlled according to the designed temperature variation; step 5: data are acquired to calculate.
