Title: Method for preventing clogging of nozzle at the time of transfer-pouring molten alloy steel
Inventor: ITOYAMA SEIJI
IPC: B22D1/00
Filed: 1993-10-20
Abstract: PURPOSE:To prevent the clogging of a nozzle by adjusting the adding quantity of Ca (Ca alloy) based on S concn. and O concn. dissolved in molten steel in a transferring vessel and vaporizing quantity of dissolved Ca in the molten steel so as to remain the dissolved Ca in the molten steel. CONSTITUTION:At the time of transferring the molten alloy steel from the transferring vessel to the other vessel through a nozzle, the adding quantity of Ca (Ca alloy) is adjusted so as to remain the dissolved Ca in the molten steel in the transferred vessel just before completing the transfer by this adjustment. At this time, in the molten alloy steel containing >=2wt% the total content of one or more kinds of components selected among Mo, V, Ti, Zr, Al and REM(rear earth element), the total Ca content satisfying the specific equation is contained. By this method, the clogging of the nozzle is prevented and the stable process production and a large quantity of production of the alloy steel can be obtd., and further, the development of breakout at the time of continuously casting is eliminated because the molten steel temp. is unnecessary to be high.

Title: Throwaway tip
Inventor: HIBATAKE TADAHIRO
IPC: B23B27/22
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To surely catch, deform and divide chips flowing unstably at the time of low depth of cut, by forming a pair of spherical projections on a nose part, symmetrically relative to a bisector for roughly bisecting the nose part and also a projecting part adjacently to the tip center side of the spherical projections. SOLUTION: In a region of low depth of cut, hollows 16 lead the flow of chips to a lower position of an inclined part 10, and makes it collide surely with projections 13 to thereby give larger deformation. Thereafter, the chips are hit against the projections 13 and bent. At that time, the chips are contacted with the two projections 13 at each one spot, two spots in total, therefore, even the chips having a narrow width and an unstable outflow direction can be caught surely. And besides, as the surfaces of the projections 13 are spherical, the contact area becomes minimum regardless of the width and the flowing direction of the chips, therefore, the flow of the chips is smooth and the cutting resistance is not heightened. Even if the chips overflow the projections 13, they collide with a projecting part 14, and are bent and divided.
