CONSTITUTION:Granulated steelmaking slag 3 crushed to <=25mm. is placed to make a layer, 5-20cm thickness, on a high temperature molten or semi-molten blast furnace slag 2 of 1,300-1,500 deg.C in a slag yard using a carrying device such as slag ladle etc. Then, water is sprinkled on the upper layer with a spray nozzle 4. By this way, SO2, H2S etc. in the process of cooling of high temperature blast furnace slag 2 is eliminated by unslagged calcium oxide contained in the steelmaking slag 3, and generation of them can be prevented to improve working environment. Suitable grainsize of above-mentioned steelmaking slag is <=25mm. and suitable thickness of the layer is 5-20cm.</description><language>eng</language><subject>DISPOSAL OF SOLID WASTE ; PERFORMING OPERATIONS ; RECLAMATION OF CONTAMINED SOIL SOIL ; TRANSPORTING</subject><creationdate>1983</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19830519&DB=EPODOC&CC=JP&NR=S5824198B2$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,780,885,25563,76418</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19830519&DB=EPODOC&CC=JP&NR=S5824198B2$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>OOSUMI KOJI</creatorcontrib><creatorcontrib>EBIHARA KOJI</creatorcontrib><title>JPS5824198B</title><description>PURPOSE:To prevent the generation of sulfurous acid gas and hydrogen sulfide gas from the blast furnace slag when cooling by layering granulated steelmaking slag on the blast furnace slag after discharging the high temperature slag into a slag yard and sprinkling water over it.
