The invention relates to a metallurgical system (1) and to a method for treating a metal product (50, 51, 52), the system (1) having: at least one treatment means (10, 20, 30) for treating the metal product (50, 51, 52); and a system controller (100) having a process section (120) for controlling and / or regulating the system (1), a data section (110) designed to detect production data of the metal product (50, 51, 52) and to provide same to the process section (120), and a specification section (130) designed to provide the process section (120) with specifications at least in the form of limits without the need for correction and limits with the need for correction, the process section (120) having a correction section (123) designed to compare the production data from the data section (110) with the specifications from the specification section (130) and, on the basis of said comparison, to make corrections in the controlling and / or regulating of the system (1), the correction section (123) being configured to carry out no correction in the event of small deviations where the production data is within the limits without the need for correction, to carry out correction calculations leading to automatic correction measures in the event of permissible deviations where the production data is outside of the limits without the need for correction but within the limits with automatic need for correction, and to initiate special measures in the event of impermissible deviations where the production data is outside the limits with automatic need for correction.

The invention discloses a rapid adjustment method for a gap nozzle of a quenching machine. The method comprises the following steps: (1) determining a zero reference: taking the side surface of a bearing seat at the front part of the quenching machine as a reference zero point; (2) transverse positioning: measuring the data of the roller bed bearing seats: measuring the mounting sizes of the roller bed bearing seats on the two sides by using a vernier caliper, and calculating a deviation value; according to the calculation result, the positioning check block with the adjustable thickness is welded to the side, with the small deviation, of the end face of the bearing seat, and the check block is welded to fix the zero point position; (3) height positioning: measuring the diameter of the working roller way by adopting an external diameter micrometer, wherein the number of measuring points is not less than five and the measuring points are uniformly distributed; calculating the average value and ovality of the diameters of the roller way; determining a header installation height compensation value according to a calculation result; the invention can greatly reduce the time for adjusting the header, reduce the increase of water consumption, and improve the quenching striking precision of the gap header.
