摘要： PURPOSE: To effectively adhere refractory to repair by allowing the repairing refractory in a projecting tube to project toward the position required to be repaired by the pressure of compressed air from a compressed air supply source connected to the tube. CONSTITUTION: The apparatus for projecting to repair comprises a projecting tube 1, a refractory charging mechanism 2 for charging a predetermined quantity of repairing refractory in the tube 1, and a compressed air supply source 4 connected to the tube 1 via a hose 3. The tube 1 and the mechanism 2 are installed on a table 5. The table 5 is so pivotally secured by a shaft 9 as to rotate the tube 1 on a rotary table 8 rotatably supported to the upper end of the strut 7 of a base 6 in the elevating direction, and elevated by a tilting cylinder 10. Thus, the direction of the tube 1 is arbitrarily selected and the projection is conducted by the pressure to repair the position to be repaired even if the position is at a high place or a remote distance.

摘要： PROBLEM TO BE SOLVED: To safely and quickly cut and remove metal, slag and refractory on the inner surfaces of immersion tubes and circulating tube in an RH vacuum degassing apparatus. SOLUTION: Whole device is shifted below the immersion tubes 1 by operating a base carriage 17 and a bit 2, upper support 8 and cutting waste chute 9 are risen. At this time, the alignment between the bit 2 and the immersion tube 1 is executed by inclining a guide rail 16. Successively, firstly, the support 8 is held to an immersion tube connecting flange 1a and fixed. Successively, the feeding speed of the bit 2 is matched to the feeding speed at the time of cutting the refractory, and the cutting in the inner surface of the immersion tube 1 with the bit 2 is started. When the rotation stops on the way of cutting, the feeding speed is changed over, and the cutting is again executed to execute the cutting to a prescribed position. The cutting waste discharged during cutting is recovered into a cutting waste bag 12 through a chute 9. After completing the cutting, the bit 2 is lowered and successively, the support 8 and the chute 9 are lowered to complete the work.

摘要： PROBLEM TO BE SOLVED: To inhibit the erosion of a part where molten steel and slug are not kept into contact with each other, except for a steel bath part, even when an oxygen sending speed is increased and a strong oxidation atmosphere is formed in the converter. SOLUTION: Magnesia carbon bricks 2a having a content of C of 15 mass % or more are lined on a molten steel contact part 1a of the converter 1, magnesia carbon bricks 2b of a content of C of more than 11 mass % and less than 15 mass % are lined on a molten steel non-contact part 1b. The erosion of magnesia carbon bricks lined on the non-contact part with the molten steel can be effectively inhibited even in high-speed blowing under conditions that the oxygen sending speed is 3 Nm 3 /min steel ton or more, and a slug volume is 50 kg/ton or less.

摘要： PROBLEM TO BE SOLVED: To accurately hold a robot hand or the like placed on a placement seat by installing a copying mechanism between a support bed placed on a floor and the lower surface of a support seat for placing a robot hand or the like. SOLUTION: The horizontal dislocation of a hand placement seat is absorbed by the rotation of a link ball 14 and a spherical bush 13 respectively around spherical centers P1 and P2 . Furthermore, the vertical dislocation of the hand placement seat is absorbed by the vertical slide of the spherical bush 13 and a spring post 12. Also, motions along the horizontal and vertical directions react with each other, thereby absorbing the tilting dislocation of a hand placement seat. According to this construction, a robot ATC and a hand ATC can be pertinently coupled to each other and a robot hand can be properly mounted. even when a floor or the like is inclined or otherwise.
