ABSTRACT:
Method for controlling a process melt of two-phase cast brass, whereby the cast properties of said process melt, the dezincification resistance of the piece cast from said melt and the required analysis corrections can be estimated. The method according to the invention is based on phase transformations in the brass occurring during solidification and cooling, on effective Cu percentage and on measurement and interpretation of the cooling curve by means of a computer which writes out the conclusions it has drawn about the quality of the melt and recommends the needed analysis corrections, whereby the alloying elements are copper, zinc and aluminum. A sample of the melt to be analyzed is poured into a crucible (A) which has a thermoelement (A1) and which is insulated (A3). From the crucible a compensation cable leads to the measuring unit (B) from which the measurement information is transferred to the microcomputer (C) controlling the measurement, treating the measurement information and writing out on the display (E) and/or the printer (F) an estimate of the melt properties, the most important phase transformations noted, the deviation of the melt from the effective Cu percentage and the analysis correction directions.
