Filed: 1993-03-31
Abstract: PURPOSE:To stably produce molten steel having low oxygen content even in the case of low-deoxidizing element contents by adding a small quantity of Al together with lime into molten slag on the molten steel in a ladle at a specific time, at the time of tapping off the molten steel from a converter. CONSTITUTION:At the time of refining the molten steel containing <0.02% C and low contents deoxidizing elements, such as <0.003% Al, <0.10% Si and 0.005-0.020% Ti in the converter, as the oxygen content is high because of the low contents of the deoxidizing elements, during the time interval from over 70% of the aimed steel tapping quantity to the completion of the whole steel tapping in the process of tapping off the molten steel from the converter into the ladle, Al of 0.15-0.50kg/ton of molten steel is added together with the lime into the molten slag on the steel surface in the ladle. Then, by executing the reduction of FeO in the molten slag, FeO content in the molten slag is reduced to prevent reoxidation of the molten steel with FeO in the slag, and the low oxygen-containing steel of <=0.0025% oxygen content can stably be produced.

Title: Compressed connection tube
Inventor: OKAMURA TAKASHI
IPC: H02G7/02
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To ensure the reduction of reflectance after compression as well by setting the surface reflectance of a compressed connection tube to a specified value or below prior to compression. SOLUTION: For compressed connection tubes that underwent surface roughing and those that did not undergo it, reflectance is measured before and after compression using ordinary pipe-like aluminum jumper sleeve S. The result of the measurement shows that significant reduction of reflectance is achieved in the surface-roughed compressed connection tubes even after compression. Good results are obtained especially when abrasive alumina is employed and its surface reflectance before compression is 100% or below, preferably 70% or below. Since these compressed connection tubes have a reduced surface reflectance, as mentioned above, transmission line facilities are harmonized with the ambient natural environment. Especially, it is possible to reduce reflectance even after compression.

Abstract: PURPOSE:To prevent the inner surface of a hose from being damaged at the time of drawing a skin from the hose by a method wherein a core member is drawn first at the time of drawing a mandrel from the hose. CONSTITUTION:A mandrel 10 comprises a core member 11 and a 13 formed of a flexible high molecular weight material releasable from the core member 11 and an inner tube resin layer 2 of a hose 6. At the time of drawing the mandrel 10 from the skin 13, only the core member 11 is drawn first, and then the skin 13 is drawn.
