External pretreating jet gun for molten iron furnace

TLDR: The structural parameters of the spray lance are as follows: The angle between the vertical axes of the main body and the round table generatrix inside the bell mouth is 10????-12????, and the inner round height is 670mm-730mm as mentioned in this paper.

Abstract: The utility model belongs to external molten iron desulphurization equipment, in particular it relates to external molten iron pre-disposal spray lance The structural parameters of the bell mouth are as follows The angle between the vertical axes of the spray lance main body and the round table generatrix inside the bell mouth is 10????-12???? The inner round height of the spray lance bell mouth is 670mm-730mm The external circle diameter of the bell mouth is 640mm-660mm, and the internal circle diameter is 445mm-465mm The change of the bell mouth parameter of the utility can greatly reduce the desulphurizer dosage during the molten iron pre-desulphurization, thus the efficiency is promoted and the cost is decreased Meanwhile, it reduces the quality of slag, iron loss and the disposal time
