Production practice of sintering technology with ultra-thick material layer
Air leakage rate of sintering machine pallet is an important measure of sintering machine pro⁃duction status, which will affect sinter mineralization rate, fuel consumption, sintering cost, sinter unifor⁃mity etc. Therefore, reducing the air leakage rate of sintering machine pallet is an important link in opti⁃mizing sintering production. This paper systematically analyses the air leakage problem of the 230m2 sin⁃tering machine pallet in Tiangang United Special Steel, determines the reason for the high air leakage rate of the sintering machine pallet, and puts forward a series of transformation measures. Through the im⁃plementation of the regular maintenance system of the sintering machine pallet, the transformation of the pallet slide-way, the improvement of the pallet fence structure , optimization of sintering production pro⁃cess and other measures, the air leakage rate of sintering machine pallet is reduced from previous about 55%to about 35%, which improves the air permeability of material layer, and reducing fuel consumption, laying the equipment foundation for ultra-thick material layer sintering. At present, the material layer thickness of 230m2 sintering machine in Tiangang United Special Steel has reached 1000mm.
