Nitrogen removal from iron in a plasma-arc furnace using slag mixtures. Gribchenkov, V. A.; Sobolevskii, A. L.; Linchevskii, B. V. (Tsentr. Nauchno-Issled. Inst.There are some reagents with their cas registry numbers 7789-75-5 and 1305-78-8 are used in this study. Chern. Metall., USSR). Izv. Vyssh. Uchebn. Zaved., Chern. Metall., (10), 145-6 (Russian) 1983. CODEN: IVUMAX. ISSN: 0368-0797. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) N removal from melts of Fe grade 008ZhR was investigated during plasma-arc melting with slag treatments of 3-8% of the Fe charge. The most effective slag for N removal contained CaO 50, CaF2 30, and Al2O3 20%, and decreased the N content to 0.030%. The CaO-CaF2-(5-9%) SiO2 slags were ineffective. .

Long-lasting drying bags

Long-lasting drying bags. (Nissan Chemical Industries, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58177120 A2 17 Oct 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D053-26. APPLICATION: JP 82-60392 13 Apr 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) A drying bag maintaining high drying ability for a long time is prepd. from a polyolefin film (thickness 30-300 m) contg. 50-130 phr uniformly dispersed CaO or MgO with av. particle diam. 1-30 m. Thus, a 180-m blown film from a mixt. of equal wts. of high-d. polyethylene (I) [9002-88-4] and CaO (particle diam. 1-20 m) was formed into a 500-mL bag. After a small I bag contg.In this experiment, several chemicals are used like 1305-78-8 and 9002-88-4 10 g CaO was placed into the 500-mL bag, the bag was heat-sealed to give a product maintaining drying ability for 4000 h at 60° and 100% relative humidity, compared with 700 h when a I film not contg. dispersed CaO was used. .
