摘要： PURPOSE:To determine the optimum specification of a continuous integrated process line in which the continuous process lines such as the continuous pickling line, cold rolling mill and continuous annealing line for a steel sheet are integrated. CONSTITUTION:The specification, operation conditions, production schedule of a material to be processed and line-shutdown information of each section comprising a line are inputted, a time (TS time) until the change of the state change of the material to be processed occurs first during processing in each section is calculated based on these inputted data, dynamic simulation based on the time is executed and the specification is corrected according to the result of the simulation. Even in the continuous integrated process line in which various kinds of lines having different characters are connected, the prediction of the actual production state is enabled in the design stage of the equipment and the study of the optimum specification is exactly executed.

摘要： PURPOSE:To stably obtain fine grains of molten metal in width direction by arranging a porous ceramic at the outlet of a nozzle body for atomizing the molten metal. CONSTITUTION:In a fine granulating apparatus for molten metal, the porous ceramic 2 is fitted at the outlet of a nozzle body 1. Liquid of molten zinc, etc., introduced in the nozzle 1 from an introducing hole 3 is mixed with gas introduced from a gas hole 4 and passed through the porous ceramic 2 to change the liquid into fine grains and is injected from the outlet 5 of nozzle. In the case of using no gas, the gas hole 4 is closed. As the porous ceramic 2, materials which do not come into reaction with the atomizing molten metal or difficult to react with the melt are selected out. Impurities in the molten metal can be removed by the porous ceramic 2 and fine grains having high purity can be obtd.
