摘要： PROBLEM TO BE SOLVED: To intercept fluid certainly and simultaneously to enhance repair of a piping and degree of freedom of route change. SOLUTION: A piping 100 is intercepted at arbitrary position except the position corresponding to an opening hole 101 formed for inserting a piping shut-off device 10 into the piping 100 by the self-movable piping shut-off device 10 provided with wheels 14. The piping shut-off device 10 intercepts the piping 100 by an outer peripheral cylindrical body 11 and an interception plate 12 and an expansion tube 13 on its outer peripheral side but certainly intercepts the piping 100 by supporting and fixing to the piping 100 not only through the friction force between the expansion tube 13 and inner peripheral surface of the piping 100 but by a support member 15.

摘要： PURPOSE:To efficiently and economically prevent or restrain the vaporization of cooling water in the cooling plate and to prevent the breakage of the cooling plate by beforehand detecting a sign of the vaporization in the cooling plate and taking the preventing measure to the breakage of the cooling plate only in the necessary cooling system. CONSTITUTION:A part of the cooling plate 4 is exposed to the inside of the high temp. furnace 1 of a blast furnace caused by wearing of the furnace wall 11 and the temp. of the cooling water is raised. This condition can be confirmed by the sign phenomenon of the vaporization, by clouding phenomenon due to the generation of bubbles in the cooling water by visually checking the condition of drainage 5 in the cooling water for cooling plate. At the time of condirming this condition, immediately, e.g. a three-way valve 8 as directional change-over valve is manually operated, and a water supplying source is changed over into a high pressure water pipe 7 which has an original pressure higher than the pressure loss due to gas-liquid two phase flow in the cooling plate 4 and a supplying/draining water piping 3 system. By this method, the generation of the vaporization of the cooling water in cooling plate is prevented from happening or the vaporizing phenomenon after its occurring can be restrained and the breakage of the cooling plate can be prevented.

摘要： PURPOSE:To restrain the remaining or the growth of bubbles in the inner part of a cooling disk by regulating the flow rate of cooling water into the cooling disk for blast furnace so as to become a specific Reynold's number. CONSTITUTION:In the cooling disk used for cooling the furnace body in the blast furnace, the flow rate of the cooling water in the cooling disk is specified to >=35000 Reynold's number Re expressed in the equation Re = flowing passage diameter X flowing velocity X fluid density/fluid viscosity. When the Reynold's number Re is >=35000 in the fluidizing condition of the cooling water in the water passage, the remaining or further, the growth of the bubbles in the inner part of the cooling disk is prevented the stable cooling capacity in the cooling disk can be secured and the blast furnace operation can be stabilized.

摘要： PURPOSE:To provide a method, in which hanging type metallic materials, etc., are set to furnace wall in a short time, in the repair of the furnace wall in a blast furnace. CONSTITUTION:In the setting work by successively hanging the metallic materials, etc., for repairing the furnace wall in the blast furmace, a sufficiently long guide wire 10 is inserted from an iron shell opening hole 3 expected to be set at the next time, adjoined to an iron shell opening hole 2 expected to be set at this time, and connected with a hanging wire 7 and the interval between a taking-in hole at the furnace top part for metallic materials, etc., 6 and the iron shell opening hole 8 expected to be set at the next time, is communicated with a wire 8. By this method, plural metallic materisl, etc., for repairing the furnace wall can surely be set in the short time of stopping the blasting and the effect of the repairing of the furnace wall is largely improved.

摘要： PURPOSE:To provide a repairing method for the furnace wall of a blast furnace which prevents the development of crack and deformation of an iron shell and can easily be executed at an extremely low cost, by stably supporting the repaired refractory over a long period. CONSTITUTION:After fitting, from the inside of furnace, an auxiliary cooling panel 5 performed with monolithic refractory 9 till the intermediate thickness of a water cooling system pipe 8 spraying material 11 is sprayed from the inside of the furnace while using studs 6 arranged to the auxiliary cooling panel 5 as a supporting material. The auxiliary cooling panel 5 is fitted so as to face the intermediate position of the existing cooling panels 4, and after completing the spraying, a force-feeding material 10 is forcedly fed for filling up a gap at the back surface side. Further, the air is vented from an air vent hole 12 in order to improve the filling property of the force-feeding material 10 and prevent the explosive crack at the initial stage. The durability can be improved by this repairing technique for the furnace wall of the blast furnace.
