At this time, respective conditions of 2.1-3.5 slag basicity(CaO/SiO2), >=10wt.% residual carbon in slag, >=4.0% carbon in molten iron, and >=1500 deg.C molten iron temp. are satisfied. After the resulting chromium-containing molten iron is subjected to rough decarburizing refining, chromium oxide in the slag is reduced and recovered so that Si content in molten steel is regulated to 0.05-0.10%. Subsequently, finish decarburizing refining is carried out, by which the chromium-containing steel of low C and N content is refined. By this method, operating time can be shortened and productivity can be improved.

IPC: B41J13/076
Filed: 1986-02-25
Abstract: PURPOSE:To early find the end of life of a paper feed roller and to prevent an error in printing by providing a paper feed roller of a two-layer structure, which is formed by covering the upper surface of the first elastic body having a discrimination pattern described at a part of the surface thereof with the second elastic body formed by material which is different from that of the first elastic body and capable of picking a sheet. CONSTITUTION:The first elastic body 4b having a discrimination pattern 4c is disposed in the periphery of a central sleeve 4d of a paper feed roller 4. The peripheral surface of the first elastic body 4b is coated with the second elastic body 4a. The second elastic body 4a is formed by material which is different from that of the first elastic body 4b and capable of picking a sheet. Thus, the paper feed roller 4 is of a two-layer structure. As the paper feed roller 4 feeds out a sheet, the second elastic body 4a gradually wears away due to friction. With the advance of abrasion, the discrimination pattern 4c described on the surface of the first elastic body 4b appears on the surface. Abrasion of the paper feed roller can be judged by recognizing the pattern 4c, and the roller is replaced to prevent an error in printing.
