IPC: C21C7/10
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To easily add the nitrogen in a short time and to restrain the lowering of molten steel temp. and the wearing of a refractory by raising the nitrogen concn. with blowing nitrogen-containing gas, while stirring molten steel in a decarburizing and degassing process of the molten steel which is executed while blowing inert gas from the bottom part of a ladle by dipping one immersion tube into the molten steel in the ladle. SOLUTION: The decarburization is executed by dipping the immersion tube 13 into the molten steel 12 while blowing gaseous argon into the molten steel 12 from a porous plug 19 and reducing the pressure in the immersion tube 13 and a vacuum vessel 14. When the carbon concn. in the molten steel 12 reaches 10-50 ppm, the vacuum degree is lowered and a valve 21 for supplying the gaseous argon, is closed and a valve 23 is opened to supply the gaseous nitrogen. Then, the nitrogen concn. in the molten steel 12 is raised to 40-60 ppm while promoting the decarburization. When the carbon concn. becomes a prescribed value having <=10 ppm carbon concn., the decarburization is completed to execute the degassing-refining for removing hydrogen and oxygen, etc. The nitrogen concn. can further be raised by blowing the gaseous nitrogen into the molten steel 12 during degassing-refining.

Title: Measuring instrument for association accuracy and vertical travel accuracy
Inventor: SUZUKI MASATOSHI
IPC: F41G1/38
Filed: 1989-11-04
Abstract: PURPOSE:To accurately measure the association accuracy and vertical travel accuracy by fitting an autocollimator to the ocular part of a telescope for sight collation and projecting a projection reticle image which is reflected by the reflecting means of a cylinder on a fixed reticle. CONSTITUTION:The autocollimator 3 is fitted detachably to the ocular part 13 of the telescope 2 for sight collimation. Then the autocollimator 3 and the reflecting mirror 4 fitted to the cylinder 1 are adjusted previously so that the projection reticle image which is reflected by the mirror 4 matches the fixed reticle 21. In this state, when there is neither an association error nor a vertical travel error between the cylinder 1 and telescope 2, the projection reticle image 18 matches the fixed reticle 21. If there is an error, on the other hand, the optical path of the returning projection reticle image 18 deviates from the optical path of projection and the association error E1 and vertical travel error E2 can be measured continuously with high accuracy irrelevantly to whether an elevation angle is large or small.
