ΠΕΙΡΑΜΑΤΙΚΗ ΚΑΙ ΘΕΩΡΗΤΙΚΗ ΔΙΕΡΕΥΝΗΣΗ ΤΗΣ ΑΝΑΓΩΓΙΚΗΣ ΤΗΞΗΣ ΝΙΚΕΛΙΟΥΧΩΝ ΣΙΔΗΡΟΜΕΤΑΛΛΕΥΜΑΤΩΝ ΣΤΗΝ Η/Κ
type: CreativeWork
description: THE METALLURGICAL PROCESS OF THE REDUCTION SMELTING OF THE GREEK NICKEL FERROUSLATERITES FOR THE PRODUCTION OF RAW FENI ALLOY IS EXPERIMENTALLY AND THEORETICALLY STUDIED. THE STRUCTURE OF THE SLAGS IS STUDIED IN ORDER TO DETERMINE THE FORM OF THE NI LOSSES AND TO DETERMINE THE CONDITIONS UNDER WHICH THE ERF PROCESS IS FAVOURED. THE RESULTS OF THE "IN SITU" INDUSTRIAL TESTS ARE PRESENTED AND THE INFLUENCE OF THE MAIN PROCESS PARAMETERS AND VARIABLES ON THE EFFICIENCY OFTHE PROCESS IS DISCUSSED. NICKEL LOSSES IN SLAG ARE DISTINGUISHED IN MECHANICAL LOSSES (ENTRAINED FENI PARTICLES) AND CHEMICAL LOSSES (CHEMICALLY BONDED NICKEL). NICKEL DISTRIBUTION BETWEEN SLAG AND METAL IS STUDIED AND THE CHARACTERISTIC EQUILIBRIUM CONSTANT IS DETERMINED. THE NICKEL TRANSFER FROM SLAG TO METAL IS ALSO STUDIED AND THE OVERALL MASS TRANSFER COEFFICIENT OF NICKEL IS DETERMINED. A SIMPLIFIED MODEL OF THE ERF PROCESS IS PRESENTED AND THE RESULTS ARE COMPARED WITH THE RESULTS OF THE INDUSTRIAL TESTS.
