摘要： PURPOSE:To dissolve the choking of devices by slimes and to contrive the reduction of the maintenance cost and stabilization of the operation of the water circulating system, by a method wherein ozone is injected in the water at the entrance side of the devices such as a heat exchanger and strainers of the water supplying system, and slimes are sterilized and stripped off. CONSTITUTION:A heat-up brine pump 32 is operated after the ozone adsorption operation is repeated and necessary ozone is adsorbed, and heat-up medium in a brine tank 31 is sent in a heat-up fin 30 in an adsorption tower 26, and when the temperature in the tower becomes about 0 deg.C, the injection of ozone is begun. Next, an ejector pump 22 is started and after an ejector 21 has begun normal operation, a control valve 35 of an ozon supplying pipe from the ozone adsorption tower 26 to the ejector 21 is opened and the ejector 21 performs reaction and mixing of ozone containing gas and treating water. By repeating above-mentioned operation, ozone can be intermittently injected in the treating water at the necessary ozone density. Thus, slimes are sterized and stripped off, and the choking of the devices is dissolved and the operation can be stabilized.

摘要： PURPOSE:To reduce the injecting amount of gaseous O3 and the operation cost by adjusting the pH concentration of cooling water a little lower to lengthen the half life of O3, when the gaseous O3 is injected into roll-cooling water. CONSTITUTION:A gaseous O3 injecting pipe 20 is parallelly connected to a water-supplying piping 10 at the outlet side of a cooling tower 7. A gaseous O3 generating and supplying device 15 is connected to the pipe 20 to supply gaseous O3 to the pipe 20 by an ejector 16, and high-pressure cooling water is supplied to the ejector 16 by an ejector pump 21. An acid injection pump 17 interlocked with the pump 21, is actuated together with the pump 21, i.e. the ejector 16. By this construction, a sulfuric acid, for instance, supplied from an acid tank 19 through a control valve 18, is injected into the cooling water of piping 10 at the suction side of a water supplying pump 9. Accordingly, the pH concentration of cooling water is lowered. This pH concentration is measured by a pH meter 22, and the valve 18 of pump 17 is adjusted to control the amount of acid to be injected, so that the actual pH concentration coincides with the aimed one.

摘要： PURPOSE:To stabilize the residence time of O3 and to keep the O3-concentration of headers at a prescribed value, by installing a branch pipe at the downstream just before water-spraying headers, and controlling the amount of water in the O3- residence-time zone of a cooling-water piping into which the gaseous O3 is injected at the upstream into a constant value. CONSTITUTION:A gaseous O3 injecting pipe 17 is parallelly connected to a water- supplying piping 10 at the outlet side of a cooling tower 7. A gaseous ozone generating and supplying device 15 is connected to the pipe 17 to supply gaseous O3 by an ejector 16, and high-pressure cooling water is supplied to the ejector 16 by an ejector pump 18. For controlling the flow rate of cooling water, a cooling-water extracting pipe 20, branched from the pipe 10 in the vicinity of headers 14, is connected to the return pipe 21 of a discharged-water receiving tank 5. A flow regulating valve 22 is provided to the pipe 20, and a flow meter 23 is attached to the pipe 10 at the upstream side of the connecting point of pipe 20. The valve 22 is controlled by a flow-rate signal outputted from the meter 23, to maintain the constant flow-rate of cooling water at the O3-residence-time zone of pipe 10, that is between the ozone injecting point A and the connecting point B of pipe 20.

摘要： PURPOSE:To reduce operation cost by injecting gaseous O3 at plural positions of a cooling water piping up to roll cooling-water headers to keep the O3- concentration at the headers equal to or larger than a specific value, as well as to reduce the amount and concentration of the O3 required to be injected. CONSTITUTION:The generation of slime is prevented by keeping the concentration of O3 at roll cooling-water headers 4 at >=0.1ppm. For this purpose, gaseous O3 is injected into the cooling water of a water supplying piping 10 at two points, for instance at the outlet side of a cooling tower 7 and the middle point of piping 10 from respective gaseous O3 generating and supplying devices 15, 16 with the aids of ejectors 17, 18. The ejectors 17, 18 are provided to gaseous O3 injecting pipes 19, 20 connected parallelly to the piping 10. An O3-containing treating water flows in the piping 10 to wash it up to the headers 4 in order to prevent the formation of slime. As the gaseous O3 is injected at the two points of piping 10, the amount and concentration of injected O3 is remarkably reduced as compared with one point injection.

摘要： PURPOSE:To prevent the adhesion of slime by a small injection amount of ozone, by using water having water quality better than that of recirculation roll cooling water as one for ozone dissolved water for injecting ozone in a roll cooling water system. CONSTITUTION:A valve 18 is opened and a valve 19 is closed to recirclate roll cooling water. When piping 9 is washed by ozone water, the valve 19 is opened and the valve 18 is closed and only fresh water is sent to the water supply piping 9 from a fresh water replenishing pipe 10 by a water feed pump 8. At a stage when water in the water supply piping 9 is replaced with fresh water, an ejector pump 17 is started to suck the fresh water by an ejector 16 and ozone is desorbed from an intermittent ozone generation and supply apparatus 14 to be dissolved in the fresh water and the water supply piping 9 is washed by ozone dissolved water. After ozone washing is finished, valves are again changed over to open the valve 18 while closing the valve 19 and roll cooling water is recirculated.

摘要： PURPOSE:To relieve the maintenance of a water filter, etc. as well as to reduce make-up water and to reduce its operation cost, by injecting gaseous ozone into roll-cooling water is prevent the generation of slime in the supplying pipe of cooling water as well as to improve the quality of a metallic strip. CONSTITUTION:For generating gaseous O3 by a gaseous-O3 generating and supplying device, gaseous O2 from a gaseous-O2 supplying device 19 is pressurized by a circulating blower 20 and is sent to a gaseous-O3 generator 21. A part of the gaseous-O2 is converted into gaseous O3, and the O3-containing gaseous O2 is fed into an adsorbing tower 22 through a control valve 23. At the time of adsorbing the O3, the O3 contained in the O3-containing gaseous O2 is adsorbed by cooling an adsorbent in the tower 22 with the aid of a refrigerator 24. The gaseous O2 from the tower 22 is sent to the generator 21 again by the blower 20 to adsorb the required amount of O3. Next, a heat-up brine pump 28 is actuated to send a heating medium into a heating fin 26 in the tower 22, to adsorb the O3 adsorbed by the adsorbent. When an ejector pump 18 is started and a control valve 31 is opened, the reaction and mixing of the O3-containing gas and the cooling water is accelerated by an ejector 16.

摘要： PROBLEM TO BE SOLVED: To prevent peeling of a rubber roll during use by fitting a sleeve-like unvulcanized rubber on a roll core metal, pressing and vulcanizing the rubber in a die. SOLUTION: An unvulcanized rubber formed into a sleeve, namely, into a center cylinder is fitted on a roll core metal 2 in such a manner that the center axis of the cylinder coincides with the center axis of the roll core 2 and that the inner surface of the cylinder of the sleeve rubber 1 covers the outer surface of the roll core metal 2. Then the rubber is pressed and vulcanized by using a die press 3. Thereby, air trapped and remaining between the roll core metal 2 and the rubber 1 can be removed, which prevents peeling on the adhesion face between the roll core metal 2 and the rubber 1 when the rubber roll is used. Moreover, air remaining in the rubber can be removed by pressing and vulcanizing, which makes the rubber itself dense to have higher strength and prevents peeling in the rubber part when the roll is used. By vulcanizing in a die press, wear resistance of the rubber roll can be improved.
