摘要： PURPOSE:To cool continuously and efficiently a high temp. metalllic strip without disturbance in its shape by specifying the fall rate of the critical temp. for each one piece of cooling rolls in said strip. CONSTITUTION:A high temp. metallic strip is run at a specified speed in contact with a cooling roll and is thus cooled. The flow of the refrigerant to be flowed in cooling rolls and rolls is set within the range where the fall rate DELTATSCR of the critical temp. for each one piece of the rolls is expressed as the related equation (the temp. in the strip before contact with the roll TS1, the temp. difference in temp. before and after the contact with the roll DELTATS). The high temp. metallic strip is continuously cooled by combining 1- plural pieces of such rolls. The generation of crease, buckling, etc. in the strip is virtually eliminated by the above-mentioned cooling method, and the commodity value is improved.

摘要： PURPOSE:To hold a bearing at lower than a lubrication limit temperature, by a method wherein a spacer is mounted between a rotary shaft and a bearing, cooling is effected from the inner surface of the spacer by means of air, and the temperature of the bearing is lowered. CONSTITUTION:A spacer 6 is located between a bearing, consisting of an inner ring 2, rolling bodies 3, an outer ring 4, and a rotary shaft 1, and the spacer 6 is located between the bearing and the rotary shaft 1. The spacer 6 is pressed in the outer diameter of the rotary shaft 1, having an inlow part 6a located in the inner diameter on the one side and a rib 6b in the inner diameter on the other side, so that a concentric condition between the rotary shaft 1 and the bearing can be held. A gap part 7 is formed with the inlow part 6a and the rib 6b of the spacer 6, and since the air can flow therethrough during rotation, air cooling is effected through passage of the air during rotation by means of the gap part 7 formed in the inner surface of the spacer 6, and this permits effective decrease of temperature.

摘要： PURPOSE:To enable simple control of the cooling rate of a metallic strip by interposing plural kinds of gaseous mixtures which are adjusted in mixing ratio and have different heat conductivity between a cooling roll and a metallic strip and cooling the metallic strip. CONSTITUTION:The required cooling rate of a cooling roll 1 is calculated by the steel kind and thickness of a metallic strip 2, line speed, required cooling rate and strip temp. Flow rate regulating valves 15, 16 are adjusted by a control devide 17 for the cooling rate to adjust respectively the flow rates of the different gases from gas sources 11, 12. The different gases from the gas sources 11, 12 are mixed with a gas mixer 10 and the mixture thereof is ejected from an ejection nozzle 8 via a supply pipe 9 toward the surface where the strip 2 and the roll 1 start contacting with each other. The cooling rate of the strip 2 is thus controlled without changing the feed and discharge rate of the refrigerant to and from the roll 1 and the temp. thereof and without changing the contact angle.

摘要： PURPOSE:To prevent shape disturbance of a strip owing to a fluctuating passing speed of the strip by constituting the cooler for the strip in a continuous annealing line of a gas jet cooler and a roll cooler and controlling the tension of the strip by the bridle rolls. CONSTITUTION:A cold rolled strip S is passed through a device disposed with a roll cooler C1 provided with many internally cooled rolls 2 movable by cylinders 3, a gas jet cooler C2 consisting essentially of a plenum chamber 4 and bridle rolls 1 for adjusting the tension of the strip S before and behind said coolers and is thus cooled from the soaking temp. for annealing down to about 400 deg.C in the stage of subjecting said strip S to an annealing treatment. Even if the passing speed of the strip S fluctuates, the deformation of the strip S is obviated by feeding the strip to the cooler C1 after adjusting the cooling temp. in the cooler C2.

摘要： PURPOSE:To maintain the adequate crown quantity of a hollow roll and to assure good tracking by sealing a heat medium into said roll and circulating the same in the roll thereby making the temp. in the width direction of the roll uniform. CONSTITUTION:In the heating zone (not shown) of a heat treatment device of a metallic strip 1, low temp. parts in contact with the strip 1 under elevation of temp. and high temp. parts that receive radiation heat directly are produced with the roll 9. The heat medium 20 filled in the hollow part in the roll 9 circulates of itself on account of the centrifugal forces by the revolution of the roll 9 and the difference in the specific gravities of the heat medium by the temp. difference in the width direction of the roll, thereby reducing the temp. differences between the high temp. parts and the low temp. parts. Also, vanes 14, partition walls 15 having heat medium passages 17, an inside cylinder 16, etc. are installed in the hollow parts in the roll 9, whereby the heat medium 20 is moved forcibly in accordance with the revolution of the roll 9 and the temp. in the width direction of the roll 9 is made uniform.

摘要： PURPOSE:To perform cooling without producing a defective shape by changing a refrigerant which is circulated to a cooling roll in accordance with the temp. of a metallic strip and regulating the temp. of the refrigerant with the temp. of the metallic strip. CONSTITUTION:A refrigerant at the inside of a storage tank 10 is sent to a cooling roll 1 via supplying pipes 11, 13, a heat exchanger 14 and a supplying pipe 8 with a pump 12 to cool a wound metallic strip 2 and is returned to the storage tank 10 via a discharging pipe 9. The temp. maintained before the metallic strip 2 comes into contact with the cooling roll 1 and the temp. of the refrigerant supplied to the cooling roll 1 are detected by temp. detectors 17, 18 and inputted into a controlling device 19. The controlling device 19 regulates a flow regulating valve 16 according to its signals and regulates the fluid supplied to the heat exchanger 14 to regulate the temp. of the refrigerant. The refrigerant at the inside of the storage tank 10 is also changed properly by a refrigerant supplying pipe 20 and cooling discharging pipe 21 according to the temp. of the metallic strip 2. Cooling is thus performed without changing the contact angle of the metallic strip 2 with the cooling roll 1.

摘要： PURPOSE:To provide a heat conducting roll for a metallic strip which can maintain the linear relation of heat conductivity with the rotating speed of a hollow roll in a high revolution region by providing holes for applying the gaseous pressure to pressurize and kill the liquid level in the roll body to the inside of the hollow roll body in addition to an inlet and outlet for conducting a heating medium. CONSTITUTION:A connecting port 6 for a pipe for introducing a heating medium and a port 9 for applying a pressurized gas are provided via a rotary joint 5 to the journal part 4 near the end of the above-described heat conducting roll body 1. A heat medium 3 is introduced through the port 6 and a liquid flow port 7 into the cavity 2 in the roll body 1 and is released through an outlet (not shown). A metallic strip wound on the outside circumference of the body 1 is heated or cooled by the surface of the body during such circulation of the heat medium. The pressurized gas past the port 9 is introduced together with the heat medium 3 through a labyrinth packing 8 into the cavity 2 to maintain adequately the liquid level of the medium 3 in the cavity 2 by said pressure. As a result, the heat exchange efficiency between the body 1 and the metallic strip traveling in contact with the outside circumference thereof is linearly improved according to the rotating speed of the roll.
