The Continuous Casting Center (CCC) is a cooperative effort among industry, university and government to conduct fundamental and applied research on the continuous casting of steel, a process that produces 95% of the world’s steel. Founded in 1989 by its director, Professor Brian G. Thomas, the CCC's objectives are (1) to develop computational models of continuous casting of steel and related processes, and (2) to apply these models to problems of practical interest to the steel industry.

Roughly 10 companies related to the steel industry contribute annually to the CCC, in addition to grants from the National Science Foundation, and collaborations with researchers in several other universities, including the Continuous Casting Consortium at the University of Illinois and the Steel Center at Colorado School of Mines.

The CCC features:

• About 10 researchers and visiting scholars, and high-performance computer (HPC) workstations, housed in W470-I Brown Hall
• Access to the HPC system, MIO, at Mines
• Advanced computational software, including Fluent, through a university partnership with Ansys, Inc.
• Abaqus, by Dassault Systèmes, and other computational tools for conducting simulations of fluid flow, heat transfer, solidification, thermal stress analysis and other phenomena related to the continuous casting process
• A physical water model of the continuous casting process, housed in W160 Brown Hall, for Senior Design and research projects
• Metallography equipment and access to advanced microscopy, (in both Hill Hall and Brown Hall), for analysis of defects in steel samples

Models of various aspects of the continuous casting process developed and licensed by the CCC are in use at many companies. These models undergo rigorous verification with analytical solutions and validation with measurements conducted on the commercial process at the steel companies, as part of student research projects. By understanding the fundamental mechanisms of how defects form during the casting process, CCC research results help to improve the efficiency and safety of the continuous casting process and the quality of steel products.

• Digital Image Correlation System: DIC is a non-contact full-field optical strain measurement technique used in conjunction with various mechanical testing techniques. Samples are speckled and a series of images is captured at a fixed frequency using high-resolution cameras synchronized with the load frame. The VIC 3D and ARAMIS software packages are used to analyze the images and compute strain measurements.
• Extensometry: Extensometers provide high-resolution, 1D strain measurements during mechanical testing. These measurements are necessary for accurate determination of material stiffness and strain-controlled testing. Special extensometers are used for internal (e.g., environmental chamber) and external (e.g., induction furnace) high-temperature testing.
• MARK-10 ESM 1500 Electromechanical Load Frame: A small, benchtop load frame that is easily configurable for tensile, compressive and bending testing of samples.

The advanced image processing capabilities of the Keyence VHX-5000 enable 3D surface reconstruction. When combined with metallurgical analysis, the library of 1D and 2D measurement tools can be used to quantify phases, voids and other structural features. Differential interference contrast and polarized light microscopy expose features in polished and etched metallurgical samples that reveal details about grain growth, microstructural evolution and compositional segregation.
• Malvern Panalytical Empyrean X-ray Diffractometer: Provides crystallographic and compositional information critical to understanding part mechanical performance. Through small- and wide-angle X-ray scattering (SAXS/WAXS), the ability to test samples at temperatures ranging from −200 °C to 1100 °C, and the capture of information on texture, residual stress and pair distribution functions, the Panalytical Empyrean demonstrates how the crystal structure of 3D-printed metals changes during operation at high and low temperatures. This piece of equipment is located on the ground level of CoorsTek.
• UltraFlex UltraHeat SM Induction Furnace: The UltraFlex induction furnace is coupled with load frames for in situ thermomechanical monotonic and fatigue testing. High temperature mechanical property measurements are critical for aerospace applications, Ti alloys, and Ni-based superalloys, among others.
• Zeiss Xradia Versa 3D X-ray Microscope: Offers cutting-edge, nondestructive tomographic imaging and grain reconstruction. X-ray tomography allows for the collection of both surface and internal renderings, which are used to distinguish between phases and identify defects such as porosity. Nondestructive diffraction contrast tomography (DCT) provides direct 3D crystallographic grain reconstructions for crystalline materials. This piece of equipment is located on the ground level of CoorsTek.

Equipment located in the Mechanical Testing Lab and the Electron Microscopy Lab in Hill Hall is also essential to high-throughput, data-informed characterization and analysis.

The high-pressure entrained-flow reactor is a laboratory-scale research vessel designed for coal, biomass, and solid waste gasification or combustion. The reactor can reach a temperature of 1650 °C and pressures to 50 atm. At the heart of the reactor is a 1 m long, 5 cm diameter silicon carbide heated tube. There are four heating zones along the length of the reactor providing uniform heating of the SiC tube. Nine optical ports provide access for optical diagnostics at three axial locations.

The gasifier is equipped for solid (fine particulates), liquid, or gas injection. The gasifier is capable of co-injecting steam, oxygen, and other gases with liquid or solid feedstocks. Gases are extracted from the bottom of the reactor and analyzed using gas chromatography and FTIR spectrometry. Unreacted particles are filtered from the exhaust stream for characterization and determining carbon balance. The gasifier facility also includes equipment for grinding, sieving, and injecting fine particulates.

The gasifier is ideal for characterizing carbonaceous materials for gasification, testing syngas processing technologies (e.g., hydrogen separation and sulfur removal), and studying gasification kinetics. The compact size of the reactor reduces operating costs and allows for rapid testing of diverse feedstocks over a large range of operating conditions. In addition, the reactor is suitable for demonstrating optical diagnostics in the harsh environment typical of gasification.

The Optical Diagnostics Lab is a 2100 ft² space that houses laser diagnostic equipment, optical tables, burners, combustion chambers, furnaces, fuel injection pressure vessels, and pulsed and short-pulsed lasers. The lab also has several research-grade cameras and a host of optical detectors, optics, and filters as well as a variety of spectrometers, detectors, optics, and other laser sources. To support research, the lab is outfitted with chemical hoods, liquid and gas storage, a wet lab, and a controlled low-humidity and oxygen glove box. Specific equipment includes:

Analytical equipment

• Keithley picoammeter/voltage supply
• Gas chromatography
• Micro GC
• Mass spectrometer
• Potentiostat/galvanostat
