In this paper, a deposition feature of a SiC:H films deposited by a RF sputtering system and a effect on the hardness of the films with various deposition conditions are investigated, and the effects of the silicon on a C:H are studied. It follows from the results that the properties of hardness can be changed with the depositing conditions. An increase of silane in the gas phase allows to deposit a SiC:H having tetrahedral structure. The sets of deposition conditions by which the different types of a SiC:H films can be deposited are obtained.

The high efficient blowing technique includes increasing oxygen supply intensity and optimizing slag forming. The oxygen supply intensity on 300t converters of No1 steelmaking shop at Bao Steel reaches 3.83 Nm3/t.min, and at Taiyuan Steel, Lianyuan Steel, Pinxiang Steel and other steel plants, the oxygen supply intensity on medium converters is in the range of 4.0-4.4 Nm3/t.min. The productivity of converter can be increased by 8-15% with adoption this technique. The whole technique, including design and manufacture of lance nozzle with reasonable pacnolontenue of outlets, technique of oxygen supply and slag forming, has been developed by CISRI to meet the need of technique transfer.
