Download Inclusion Control in Calcium Treated Steels Book in PDF, ePub and Kindle
Calcium alloys are widely used for controlling the composition and morphology of nonmetallic inclusions (oxides and sulfides). By fine-tuning the calcium treatment, producing very clean steels with good fatigue limits is possible, as is improved machinability steels covering a wide range of machining speeds from carbide tool machining to ceramic tool machining. When producing such steels the steelmaker faces a double problem: adjusting the quantity of calcium to the inclusions to be modified, and forecasting the partition of calcium between oxides and sulfides. To help the steelmaker, two developments were achieved. First was a thermodynamical model predicting the partition of calcium between oxides and sulfides and the compositions of oxides. Second was the analysis of inclusions extracted from steel by nonaqueous electrolyte dissolution to check the model and to provide inclusion ratios like (Ca/AI)oxide and Casulf to be correlated with steelmaking practice or a machinability index.

Download Slag-Steel Reaction and Control of Inclusions in Al Deoxidized Special Steel Book in PDF, ePub and Kindle
This book focuses on influence of slag-steel chemical reaction on control of inclusions in Al deoxidized special steel. Readers learn about the control of inclusions in Al deoxidized special steel refined with high basicity high alumina slag. This refining slag system was developed by the authors and used to target low melting point inclusions. This book is useful for university teachers, graduate students, researchers and engineers who are engaged in the field on control of non-metallic inclusions in steel, particularly those who are exploring innovative and optimal technologies for more efficient control of inclusions and improved qualities of steels.

Download Quantitative Image Analysis Methodology for High-Sulfur Calcium-Treated Steels Book in PDF, ePub and Kindle
Alloy steels containing 0.020% sulfur or more and greater than 20 ppm oxygen are being calcium treated to improve machinability and enhance sulfide shape control. Although from a process control perspective, the success of calcium treating can be measured by the bulk calcium content of the steel, the chemical composition of the steel does not indicate how sulfide and oxide inclusions have been modified by calcium treating. Hence, to characterize an inclusion distribution in a heat of steel, quantitative metallographic techniques are required.

Download Use of Calcium in Inclusion Shape Control of High-Strength, Low-Alloy Steels Produced by the Direct Reduction-Electric Furnace ProcessOriginal Experimental Data Were Measured in U.S. Customary Units Book in PDF, ePub and Kindle
The use of a high charge of reduced pellets (91 to 94 percent iron) in the electric furnace enables steels containing a maximum of 0.010 percent sulfur to be obtained without desulfurization. A typical sulfur value is 0.007 percent for a 100 percent pellet charge. At such low sulfur levels, it is shown that good inclusion shape control is obtained by simple additions of calcium silicon to the ladle. Various methods of evaluating transverse ductility in hot-rolled, high-strength, low-alloy (HSLA) steels are compared. A relationship is obtained between the ratio of transverse to longitudinal Charpy shelf energy values and projected inclusion length, which is upheld for a wide range of steel compositions. A minimum Charpy ratio of 0.7 is required for a given severe stretching application. The influence of manganese and sulfur contents on transverse ductility is also considered.
