Abstract: The method and computer-program comprise generating (I) a new charge, coordinating (IV) a heat treatment program to the charge, manually applying (VI) a charge thermoelement on the charge, sending (VII) the heat treatment program to a storage-programmable control of a furnace, transporting (VIII) the charge in the furnace, starting and carrying out a heat-treatment cycle, and discharging the charge from the furnace. The heat treatment program is associated to the charge exclusively in the first charge and the charge thermoelement is applied on the charge to the charge in the first charge. The method and computer-program comprise generating (I) a new charge, coordinating (IV) a heat treatment program to the charge, manually applying (VI) a charge thermoelement on the charge, sending (VII) the heat treatment program to a storage-programmable control of a furnace, transporting (VIII) the charge in the furnace, starting and carrying out a heat-treatment cycle, and discharging the charge from the furnace. The heat treatment program is associated to the charge exclusively in the first charge and the charge thermoelement is applied on the charge to the charge exclusively in the first charge. A new charge is generated in the following charge such as a process step with number of pattern charge, whose heat treatment program is used, and a program step with an automatic coordination of the pattern program belonging to the selected pattern program to the charge. The coordination of heat treatment program to the charge is defined as pattern charge exclusively in the first charge. The charge is defined as pattern charge after the discharging of the charge from the furnace. The pattern program belonging to the pattern charge is automatically generated with explicit program segment duration exclusively in the first charge after the heat treatment cycle and after defining the charge as the pattern charge. The combination with the process and the computer program is retrievable for automatic generation of technological prescription to heat treatment of metallic workpieces in the furnace by values for a material of respective workpiece, information to heat treatment process and technical information of the respective furnace, gradual specification or generation of pre-calculatable parameters for the heat treatment of the workpiece, and by a computer generating the heat treatment program with databases and a programmable storage of generated heat treatment program and/or the request for activation of heat treatment in the furnace in which a material group and the material are selected and determined in dependent upon the selected material to the heat treatment process in the first program step. The data of the workpiece charge such as wall strength input, a compression geometry, a charge weight and a charge structure is selected and automatically calculated to virtual wall strength in the second program step. A heating-up and quenching characteristics dependent and/or manually changeable by materials are integrated in the third program step from the virtual wall strength together with the data of the charge and the available parameter. In the fourth step, the first data from the selected material to the treatment parameter and data of the selected heat treatment process is loaded to a prescription structure existence and is constituted from the prescription structure existence under use of the data from a user interface such as heating characteristics and deterrent characteristics. The values are determined by prescription segment such as segment duration, temperature, ramps rising and/or temperature ramps and pressure, where a technological heat treatment prescription is automatically generated in the fourth program step. The heat treatment prescription is stored in the program database, and/or for the heat treatment of metallic workpieces to the industry furnace. In the program database, the heat treatment program is selected that is associated to the charge that is defined as pattern charge. After the termination of the heat treatment, the pattern charge is automatically generated to the pattern program belonging to the pattern charge with explicit program segment duration, which is again discarded in the program data bank. The use of user surface for creating the pattern charge is selected in the option as pattern charge.
