The slag splashing technology consists in the splashing of the left over slag from previous heat by blowing of nitrogen gas on it towards the hot face of the converter through a blowing lance. It consists of coating the slag on the converter lining by freezing the liquid slag on the walls of the converter.
Advantage of slag splashing
The advantages of the slag splashing are as follows.
Increase in the lining life of the converter.
Yield improvement due to lesser slopping because of increase in the converter volume
Lesser consumption of flux because of dissolution of basic slag during the steel making process.
The melting of the low melting phase of the slag lining results in the rapid formation of a basic slag and the rapid dissolution of the CaO from slag coating by SiO2 in converter slag. This leads to rapid de- phosphorization.
Slag splashing helps in recycling of the steelmaking slag.
The answer by vishal is well defined and i think it served well the question, in addition to which i would like to add, the tapping temp of steel is 1660 deg cel an average, so definitely slag temp will be higher than that, opening a high temp is never in favour for refractory lining considering thRead more

We add considerable amount of raw dolomite to bring down the temp of slag depending on visual condition of slag, than the lining temp, followed by the nitrogen bowing at controlled rate.
Slag will stick to lining only if slag temp is lower than the furnace lining temp,
Thus in layman’s language, splashing is the coating of retained slag after tapping to refractref lining to inhance ita life.
Slag splashing is a process of using formed slag as refractory layer in BOF steel making process by using N2 gas. Slag splashing -) additional refractory layer making.
