This article presents aspects regarding the possibilities of optimizing the quality of the elaboration of metallurgical melts by determining their physical-chemical properties. Thus, the article analyzes and presents methods for determining the viscosity and electrical conductivity related to metallurgical melts. Among the viscosity determination methods, two methods are presented, namely: the rotary viscometer method and the electro-vibratory viscometer method. Determining the electrical conductivity of a metallurgical melt is also of particular importance for ensuring the quality of the elaboration and refining of the melt. The article also presents the possibilities of using and implementing computer systems that ensure the accuracy of determining the physical-chemical properties of metallurgical melts, as well as examples of the use of physical-chemical sensors and specific computer systems for determining the analyzed parameters. The specific electrical conductivity measurements of oxide melts are performed by direct methods (by contact), with Ohm's law as a starting point. Thus, the article presents the voltmeter-ammeter method and the point method (or the zero method). The novelty of this article is the description and the use of specific methods and sensors for certain determinations (viscosity and electrical conductivity) for metallurgical melts. The motivation here is the presentation of the authors' research in the addressed field. The article presents an original contribution of the adaptation and use of some methods for determining some physico-chemical parameters, including specific sensors, in the field of the elaboration of metal alloys, with the aim of optimizing their quality.
本文介绍了通过确定冶金熔体的物理化学性质来优化其质量的可能性。因此，本文分析并介绍了与冶金熔体相关的粘度和电导率的测定方法。在粘度的测定方法中，介绍了两种方法，即旋转粘度计法和电动振动粘度计法。测定冶金熔体的电导率对于确保熔体的加工和精炼质量也非常重要。本文还介绍了使用和实施计算机系统的可能性，这些系统可以确保冶金熔体物理化学性质的测定精度，以及物理化学传感器和特定计算机系统在确定分析参数方面的应用实例。氧化物熔体的具体电导率测量是通过直接方法（接触）进行的，以欧姆定律为起点。因此，本文介绍了伏特计-电流表法和点法（或零法）。本文的新颖之处在于描述和使用特定的方法和传感器进行某些冶金熔体的测定（粘度和电导率）。这样做的动机是介绍作者在所涉及领域的研究。本文提出了在金属合金加工领域中，对某些物理化学参数（包括特定传感器）的一些方法的改编和使用的原创性贡献，旨在优化其质量。
