Title: Dephosphorizing method for molten steel
Inventor: NAKAMURA HIROMI
IPC: C21C5/36
Filed: 1986-03-04
Abstract: PURPOSE:To dephosphorize the P in a molten steel as stable Ca3(PO4)2 into molten slag by adding a dephosphorizing agent and slag forming agent essentially consisting of MgCO3 into a converter at the point of the time before or after the end of decarburization refining at the time of executing steel making refining in the converter. CONSTITUTION:Gaseous O2 is blown from a lance 14 to the molten iron in the oxygen top blown converter 10, etc., to refine the molten iron to the molten steel 12 by oxidation decarburization of the carbon contained therein. Calcined dolomite and quicklime are thrown as the dephosphorizing agent to the molten steel 12 at the point of the time before or after the end of the decarburization refining reaction to oxidize the P in the molten steel to P2O5 and to bring the same into reaction with CaO, by which the P is dephosphorized and removed as the stable Ca3(PO4)2 into the molten slag. Since this dephosphorization reaction progresses at a low temp., the MgCO3-contg. slag forming agent such as calcined dolomite or magnesite is added thereto after the dephosphorization so that the temp. of the molten slag 20 is decreased by the endothermic reaction by the decomposition of the MgCO3 to MgO and CO2. The P is thus dephosphorized in the stable form as Ca3(PO4)2 into the molten slag 20.

Filed: 1981-03-31
Abstract: PURPOSE:To reduce the number of faulty products in the manufacturing process by a method wherein a protective plastic film is applied after the formation of an X-ray transmitting window on an Si substrate in the manufacture of a highly reinforced, long life, large mask for exposure to a long wave X-ray. CONSTITUTION:An SiO2 thick film 12 and an Si3N4 thin film 13 are piled on the both sides of an Si substrate 11 of a principal face (100). The Si3N4 film 13 on the back side is etched into windows 14. Next, Cr and Au are laid for the formation of a ground layer 15. The layer 15 is then coated with a positive type resist 16 which is then exposed to light and developed for very narrow windows 17. The resist 16 is removed after the coating with Au of the interior of the windows 17. Au 18' serves as a mask in etching the ground layer 15 into an X-ray absorbing pattern P. Next, the SiO2 film 12 on the other side of the substrate 11 is subjected to etching, with the Si3N4 film 13 serving as a mask, first in an HF solution and then anistropically in a KOH solution for the formation of a window 19. A proper choise of films 12 and 13 thickness results in the formation of an approximately 10mm.X10mm. large window thanks to decrease in the shell forming strain on the frame F. Next, a polyimide coating 20 is applied, and the SiO2 film 12 exposed in the window 19 is etched away to complete the entire process.
