The Corex- bidding Since the eighties Voest Alpine developed the ember diminution process. The Corex- Process is an alternative to the conventional gamy metallic element mathematical product because bitter metal is produced without snowfall. Since 1981 lump ore, pellets and sinter have been successfully tested. The well-nigh important advantages are: Only coal quite of coke is apply Lump ore, pellets may be used The Process: The earthy solids are iron ore, coal and additives. These lead components are charged via a lock system. The coal gets through a come guide from a storage stack away (number 3 in the picture) into the melter mishandleifier. 1 In the upper severalise of the melter bollocks upconadeifier the coal is completely dried and vaporise with the reducing gas which has a temperature of 1100° C. The reduction proceeds rapidly, hence enhancing the conversion from coal to coke which is gasified and with oxygen winded in. The ga s flows in the cylindrical part of the melter gasifier and because of this a motionless fluidered bed occurs. upstream of the tuyeres oxygen reacts with carbon to a casting of CO2 which is therefore converted to CO by employ coke. The temperature of the fluidered bed is mingled with 1600 and 1700° C. After leaving the melter gasifier the longing raw gas is merge with chill gas to reach a temperature of 900°C. After this the gas is cleaned in the reduction screw. 4 Part of the pre- cleaned gas goes into a Venture 5 scrubber to obtain cooling gas. The hunky-dory particles, which are separated from the gas, are recycled into the melter gasifier. In the reduction shaft 2 the iron ore is reduced to sponge iron. The hot sponge iron goes then from the reduction shaft via screw conveyers and drops by gravity into the melter gasifier. In the fluidered bed the fall of the material is strongly decelerated. In the melter gasifier the sponge iron is heated up and fluid to form a hot metal and a convert bath at the ! bottom. At least the hot metal and slag are tapped every three hours at a temperature of...If you want to get a full essay, bless it on our website: BestEssayCheap.com
