Special Issue Information

Dear Colleagues,

Casting is one of the most important shaping processes largely used and consolidated throughout the world to produce near-net-shaping parts. Its advantages compared to other manufacturing processes are evident: relatively low production cost and time, high ranges of thicknesses and masses allowed, the possibility to shape alloys that are only castable (cast iron or certain light alloys), high adaptability to the requirements of mass production, and last, but not least, the excellent bearing quality of the casted parts. However, all of these advantages could be lost if the process parameters are not correctly calibrated to obtain nearly defect-free casting components. In most foundries, such parameter calibration is entrusted to experience rather than to real knowledge of the rules governing the solidification phenomena. A comprehensive understanding of those rules is still unknown to the academic world and represents a formidable challenge. This Special Issue will collect recent research works about casting and solidification processing in order to give the reader an overview of the actual knowledge about casting phenomena. Papers dealing with experimental, theoretical, and numerical analyses of casting and solidification processing are welcome.

We were asked by the Journal Metals to be the Guest Editors for a Special Issue devoted to “Casting and Solidification Processing (Second Edition)”. Given your expertise in the field, we would like to invite you to submit a manuscript to be considered for inclusion in thia Special Issue. Manuscripts should be submitted through the journal’s web platform. There will be a slot activated for the Special Issue “Casting and Solidification Processing (Second Edition)”. Please do not forget to “tick” the correct box accordingly. The manuscripts will undergo the standard review process of the journal and will be judged exclusively based on their scientific content.

We look forward to hearing from you at your earliest convenience.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The goal of the fluidity test is to evaluate the ability of the melt to fill the cavity of the mold, which is one of the factors affecting the final quality of the castings. It is a technological test that is basically not standardized, therefore it is realized in different forms, for example using “horizontal” and “vertical” molds. The “horizontal” mold makes it easier to fulfill the condition of repeatability, therefore it was used to calculate the capability of the test by the Measurement Systems Analysis (MSA) method. The results of the tests in both molds were used to calculate regression equations that allow the fluidity to be determined with strong reliability based on variables such as melt temperature, casting speed, and mold temperature. In addition, the effects of input data variability (uncertainty) on the resulting fluidity value were analyzed using regression equations and the Monte Carlo simulation. The contribution of the article is the analysis of the capability of the measurement process of the fluidity and a prediction of the results of its tests using the Monte Carlo simulation method.

A three-dimensional model is established to investigate the effect of argon injection mode, argon flow rate and casting speed on the gas–liquid two-phase flow behavior inside a slab continuous casting mold. The Eulerian–Eulerian model is employed to simulate the gas–liquid flow, and the population balance model is applied to describe the bubble breakage and coalescence process in the mold. The numerical simulation results of the bubble size distribution are verified using the water model experiment. The results show that the flow field and bubble distribution are similar between the argon injection at the upper submerged entry nozzle (SEN) and tundish upper nozzle (TUN), while the number density is larger for the argon injection of TUN. The coalescence rate of bubbles and the bubble size inside the mold increase with increasing argon flow rate. When the argon flow rate exceeds 4 L/min, the flow pattern of liquid steel changes from double-roll flow to complex flow, with aggravation of the level fluctuation of the top surface near the SEN. When the casting speed increases, the bubble breakup rate increases and results in a decrease in the size of bubbles inside the mold. At a high casting speed, the flow pattern tends to form double-roll flow, and the liquid level at the narrow face of the top surface increases. Full article
