摘要： PROBLEM TO BE SOLVED: To provide a boring apparatus which is more compact in structure and smaller in the number of hoses than that of the conventional apparatus, by positioning the hitting part of a shank rod integrally provided with a large diameter hitting part and bar-like small diameter parts in an interspace between a front cylinder and a rear cylinder and arranging its small diameter parts at both sides along the shaft direction of a drifter body so as to fit to cylindrical hitting pistons at both sides. SOLUTION: In the case of applying a reverse hitting, when the drifter 1 is retreated, high pressure oil comes into a pilot valve device 45 for hitting from a port Pa. At this time, the pressure oil acts on a pilot Pd from a feed retreating circuit for retreating the drifter 1. When the pressure oil overcomes the pushing force of a spring 59, a valve 60 is changed over, and the pressure oil from the port Pa comes into a valve device 43 for reverse hitting after passing through a port Pi to operate a piston 33 for reverse hitting. At this time, returning oil is returned back to an oil tank from a port Pc through a port Ph from a port Pj.

摘要： PROBLEM TO BE SOLVED: To provide a sealing structure which shortens the projecting length of cooling water piping and a protecting tube from an iron shell because of flexible sealing structure even when a stave cooler is thermally deformed and which provides a function for restraining the excessive thermal-deformation of the stave cooler.
SOLUTION: In the structure for sealing a cooling water pipe protecting tube 3 in a stave cooler 1 and an iron shell 4, a corrugated thin sheet 7 having projecting and recessed parts having a concentrically circular shape is arranged between an inner cylinder 5 welded on the outside of the above protecting tube and a cylindrical sealing box 6 welded to the iron shell. Desirably, the maximum outer diameter (d1) of the inner cylinder welded on the outside of the protecting tube is larger than the minimum inner diameter (d2) of the cylindrical sealing box welded to the iron shell, and the maximum outer diameter part of the inner cylinder is positioned in a more outer part of the furnace compared to the minimum inner diameter part of the cylindrical sealing box.

摘要： PROBLEM TO BE SOLVED: To provide a double structural cooling tube cast into a stave cooler, in which high cooling capacity is obtained by strengthening the stickiness between the inner tube and the outer tube thereby increasing the thermal conductivity. SOLUTION: In the cooling tube in the stave cooler used for cooling the furnace wall of a blast furnace, an electric furnace, etc., plural outer tubes 2 are disposed on the inner tube 1 cast with a cast iron at interval to form the double tubes, and a coating material 3 is applied on the surface of the inner tube 1 at the interval between the outer tubes 2, and the outer diameter of the inner tube 1 and the inner diameter of the outer tube 2 are defined by an inequality. The inequality is D1>d2>D1-0.5 (wherein, D1 is the outer diameter (mm) of the inner tube and d2 is the inner diameter (mm) of the outer tube).

摘要： PROBLEM TO BE SOLVED: To improve the cooling capacity by devising shapes of cooling water passages in a rolled plate-made stave cooler, and to make an existing iron shell opening hole usable. SOLUTION: One pair of mutually facing one pair of (1) U-shaped water passages, (2) L-shaped water passages, (3) chevron-shaped water passages, (4) U-shaped water passages and chevron-shaped water passages and (5) L-shaped water passages and chevron-shaped water passages are formed respectively. The opening hole of the rolled plate end surface in each water passage is closed with a plug, and a water supply hole and a water discharge hole introduced to the outside surface of the rolled plate from each end part of the water passage are arranged. Thus, a water supply pipe and a water discharge pipe are made of the rolled material having fine and uniform structure and high strength and heat-conductivity and can collectively be set and the existing iron shell opening hole parts can be used as they are. Further, the construction period can drastically be shortened and the downtime of a blast furnace can be shortened. Furthermore, the long service life of the stave cooler can be expected without lowering the iron shell strength.
