___An Absence in converter of bottom blowing vertically located furms several simplifies the design a device for catch and cooling leaving gas and greatly reduces the general sizes a device. But together with that need catch gas at ascent of the converter from horizontal position in vertical (at the beginning initially of blowing) and at slopping of the converter after completion blowing — causes the complication to designs device. In the same way either as beside converter of upper blowing, use the systems of the tap and cooling leaving gas with their burned and without burned.
___A bottom blowing of fluid metal of streem oxygen in defensive gas shell noticeably changes the features of oxygen convertered process in contrast with upper blowing by oxygen. In the first place this influences of mixed metallic bath upon intensity. Increase to intensities of mixed both directly streem blowing, and bladder CO (formed as a result of oxidations of carbon) brings about to certain reduction oxideredslag i.e. reduction in its contentses oxides ferric, brings about increase the output to suitable product. Lowered oxidered slag predestines and more high remaining contents manganese in metal that accordingly causes the reduction everyday ferromanganese (on 0,35…1,7 kilograms on ton become).
___If compare change the contents of the admixtures in metal on move of blowing, in converter b.ottom blowing in contrast with converter upper blowing, that possible sees that nature of the change concentration carbon and silicon in process smelting trunks little differ. Exist the differences in change the contentses manganese and phosphorus. Moreover most successfully under bottom blow deletes phosphorus when presenting together with oxygen dusttype lime. In this connection in bottom process is obligatory blowing together with oxygen of lime. Using of lump lime in bottom process hopeless, since in this case is not provided necessary degree of the removing of phosphorus from metal. The Degree of the removing the sulphur under bottom blow several above, than under upper blowing.
