摘要： PROBLEM TO BE SOLVED: To provide a structure for cast copper stave cooler with which the joining strength of the copper casting with a cooling water passage at the outer part and the reliability are high and the stave cooler can sufficiently restrain the deformation becoming a convex-shape toward the inside of a blast furnace.
SOLUTION: In the structure of the cast copper stave cooler for cooling the furnace wall in the blast furnace, the cooling water passage is formed at the outer part of the above cast copper by casting a steel pipe having a stopper for preventing the fall-out in the outer periphery, at the end part of the cooling water passage arranged in the inner part of the cast copper. Projection having reverse tapered shape toward the furnace outside of this cast copper, is cast to hold castable refractories with the projection.

摘要： PROBLEM TO BE SOLVED: To provide a sealing structure of joint between stave coolers with which when filling up castable refractory in the gap between an iron shell and the stave cooler at the repairing time in a blast furnace while the stave cooler is installed, the leakage of the castable refractory from the joint between the stave coolers can be prevented.
SOLUTION: Pressing plate fixing bolts 2 for fixing a pressing plate 4, are fitted to the stave cooler 1 so as to stick a water-absorbing/shrinkable sealing member 3. Successively, the pressing plate is inserted and shut in with the nut 2a for fixing. In such way, after installing the pressing plate in the inner surface of the furnace at the one side edge part of the stave cooler, the castable refractory is filled up into the back surface of the stave cooler.

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.
