摘要： This invention relates to a method of controlling the temperature of a heating furnace which has at least one furnace zone capable of being controlled by heating means and which conveys materials to be heated, that are introduced thereinto, by conveyor means such as a walking beam or a pusher so that the materials are heated to a predetermined temperature until they are withdrawn from the discharge side.More specifically, the present invention relates to a method of controlling set furnace zone temperature of the heating furnace when the materials to be heated, that are introduced into the heating furnace, have different temperature elevation patterns. The method of the invention is specifically characterized in that the predetermined set temperatures of each zone is used when the temperature elevation patterns of slabs are different with each other. The invention is directed to minimize the idle time inside the furnace when the materials having different temperature elevation patterns are sequentially introduced into the furnace, in order to conserve energy. The method is especially effective when the cold and hot materials are introduced into the furnace.

摘要翻译： 本发明涉及一种控制加热炉温度的方法，该加热炉具有至少一个能够由加热装置控制的炉区，并且通过输送装置（例如步进梁或输送装置）传送待加热材料， 推动器，使得材料被加热到预定温度，直到它们从排出侧排出。 更具体地，本发明涉及当被加热的材料被引入加热炉中时具有不同的温度升高图案的方法来控制加热炉的设定炉区温度。 本发明的方法的特征在于，当板坯的温度升高图案彼此不同时，使用每个区域的预定设定温度。 本发明旨在使具有不同温度升高图案的材料被顺序地引入炉中以最小化炉内的空闲时间，以便节约能量。 当将冷和热的材料引入炉中时，该方法特别有效。
