RESEARCH ON THE PROCESS OF IMPROVING THE COLD AND HOT STATE BREATHABILITY OF THICK MATERIAL LAYER SINTERING
Thick layer low-temperature sintering technology is currently widely used as an advanced sintering technology,based on the solidification theory of calcium ferrite and the automatic heat storage effect of the sintering process.This technology has the effect of reducing the consumption of sintered solid fuel and improving the performance of sintered ore.Currently,the feeding thickness of sintering machines has generally reached 800 mm or even higher.Feeding thickness of Angang sintering machine has already achieved over 800 mm,but the permeability of the sintering process is greatly affected by the raw fuel conditions and process equipment,which affected the stability of the sintered mineral quality.Therefore,it is necessary to conduct a more in-depth study on the influence of thick layer on the breathability of the sintering,propose optimization and control measures,so as to improve the cold and hot state breathability of the sintering process and meet the requirements of thick layer sintering.increase the output of sintered ore while reducing solid fuel consumption,and improve the quality indicators of sintered ore.While increasing the quantity of sintering minerals,reducing the consumption of solid fuel and improving the quality index of sinter.
