A method of and a system for controlling the cooling of a hot-rolled steel sheet after hot rolling. The method comprises: determining a target value of a transformation rate required for obtaining mechanical properties ultimately expected from the hot-rolled steel sheet; determining the fraction of gamma to alpha transformation of the hot-rolled steel sheet, in a section in which the cooling is controlled, by at least one transformed fraction detector; and measuring an elapsed time from the start of cooling. Then, calculating the transformation rate of the steel sheet in the cooling stage from the gamma to alpha transformed fraction and the elapsed time; and controlling the conditions of cooling so that the transformation rate in the cooling stage coincides with the target value. |

282,750. Eisen - und - Stahlwerk Hoesch Akt.-Ges., and Heidenhain, W. Dec. 28, 1926, [Convention date]. Resistance furnaces.-In the hardening of articles of iron, steel or other ferro-magnetic materials, the articles are held in tubes 2 of an electric furnace 1 which is heated by a coil 3 by a magnetic field produced by a coil 6 until the magnetic change occurs, when they slide down the tubes 2 being heated to the hardening temperature before they drop into the tempering bath 9. The furnace 1 is pivoted on a shaft 7 and is oscillated by a cam 8. Cooling tubes 5 through which water circulates are arranged outside the furnace 1 to protect the coil 6 from heat radiating from the furnace 1. |
