摘要： PURPOSE:To effectively execute cooling of high temp. steel plate by correcting necessary cooling time from deviation between the standard cooling starting temp. and the actual cooling starting temp. and average cooling velocity and modifying shifting velocity for the steel plate. CONSTITUTION:The high temp. steel plate after hot rolling or after ejecting from a heating furnace, is forcedly water-cooled in order from end part of carrying direction, to make temp. of the steel plate at the time of stopping the water-cooling to about 250 deg.C. In this cooling method, the temp. deviation is calculated from cooling starting temp. found by the standard cooling starting temp. decided as function, such as thickness of cooling steel plate, etc., and the cooling starting temp. finding by measuring value before cooling starting, etc. Next, the standard cooling time decided for the thickness of cooling steel plate, the necessary cooling time is corrected by using the above temp. deviation and the average cooling speed between 250-150 deg.C at the time of cooling the steel plate, and the shifting velocity of steel plate is modified, so as to attain this cooling time. In this way, the material quantity at the end part of steel plate is stabilized and the productivity is improved.

摘要： PURPOSE:To obtain the thick steel plate having a good plate shape by taking the fore step of the cooling process in slit jet cooling on the upper and lower faces, the rear step in the upper face pipe laminer cooling and lower face spray cooling, and specifying the falling amount of the surface temp. of the steel plate due to the slit jet cooling. CONSTITUTION:The thick steel plate 3 of immediately after hot rolling is transferred by a table roller 4 by an on-line and delivered to the primary cooling device 1. The upper and lower faces of the thick steel plate 3 are cooled by the cooling water flow fed from the upper and lower slit jet nozzles 7, 7 in the primary cooling device 1. The thick steel plate 3 is transferred by a roller 4, delivered to the secondary cooling device 2 and cooled respectively on its upper face by the cooling water flow from a pipe laminer nozzle 8 and on its lower face by the cooling water flow from a spray nozzle 10. In this case the temp. fall amount of the surface temp. of the thick steel plate 3 due to the slit jet cooling is taken >=100 deg.C.

摘要： PURPOSE:To manufacture the steel plate of aiming quality stably by cooling it so as to make the temp. at the four peripheral face and center part of the steel plate uniform in case of the adjustment of the steel plate temp. in case of rolling the steel plate so as to make in the material quality on the rolling line. CONSTITUTION:A hot rolling steel plate 1 is rolled in the thick steel plate of aiming quality by a finishing rolling mill 5 by cooling it with an intermediate shower device 4 through a rough rolling mill 3 with transferring it in the arrow mark A direction on a roller table 2, in case of the rolling of the steel plate which makes in the material quality on the rolling line like a controlled rolling stock, acceleration cooling and direct hardening stock. In this case the temp. in the width direction and longitudinal direction of the steel plate 1 coming out of the rolling mill 3 is measured by the scanning type thermometer 6 which takes the scanning angle theta at 50 deg.. The measured value is inputted into a computer 8 as the temp. distribution on the whole plate face via a signal convertor 7. The computer 8 determines the temp. drop of the four periphery of the steel plate and its range and after cooling by the intermediate shower 4 by classifying the four periphery of the steel plate into the width end part and tip rear end part and by deciding the cooling water feeding quantity to each end part, it is rolled to the target material with a finishing rolling mill 5.

摘要： PURPOSE:To prevent the formation of an ununiform structure and to reduce the cost of equipment by installing a primary cooling apparatus in which a hot rolled steel plate is cooled in a restrained state and a secondary cooling apparatus in which the steel plate is cooled in a nonrestrained state so as to enable uniform cooling and reduction in the size of equipment. CONSTITUTION:A hot rolled steel plate is transferred into a primary cooling apparatus 5 on a line with table rolls 9. An upper pressing roll 19, an upper wringer roll 28 and an upper slit jet nozzle 20 are lowered to restrain the steel plate, and the upper and under sides of the steel plate are cooled with cooling water from slit nozzles 20, 21. The steel plate is then transferred into a secondary cooling apparatus, where the upper and under sides of the steel plate are cooled with cooling water from pipe nozzles 36, 58 and cooling water from spray nozzles 46, 59, respectively.
