    Abstract: Devices may be in contact with molten metals such as copper, for example. The devices may include, but are not limited to, a die used for producing articles made from the molten metal, a sensor for determining an amount of a dissolved gas in the molten metal, or an ultrasonic device for reducing gas content (e.g., hydrogen) in the molten metal. Niobium may be used as a protective barrier for the devices when they are exposed to the molten metals.

    Abstract: PROBLEM TO BE SOLVED: To provide a porosity detection method for a continuously-casted product.SOLUTION: A computer executing a software algorithm may be used to detect a depression in a temperature profile. The temperature profile may be smoothed to eliminate noise. Next, the temperature profile's center may be extracted. A mathematical function may be fitted to extracted data. An algorithm used to fit the mathematical function may guarantee that the fitted curve's peak may be below the actual temperature data's peak. Next, residuals may be calculated by subtracting the fitted curve from the actual data. If there is a dip at the center, then the residuals in the center may be less than zero. The software algorithm executing on the computer may then make a decision based on a sign of the residuals. For example, residuals less than zero may indicate bar porosity. Residuals above zero may indicate no porosity.

    Abstract translation: 要解决的问题：提供用于连铸产品的孔隙度检测方法。解决方案：执行软件算法的计算机可以用于检测温度分布中的凹陷。 可以平滑温度曲线以消除噪声。 接下来，可以提取温度曲线的中心。 可以将数学函数拟合到提取的数据。 用于拟合数学函数的算法可以保证拟合曲线的峰值可能低于实际温度数据的峰值。 接下来，可以通过从实际数据中减去拟合曲线来计算残差。 如果中心有倾角，则中心的残差可能小于零。 然后，在计算机上执行的软件算法可以基于残差的符号做出决定。 例如，小于零的残差可能表示棒孔隙度。 零以上的残余物可能表示无孔隙度。

    Abstract: A system for melting a substance may be provided. The system may comprise a microwave generator, at least one wave guide, a melter assembly, and at l east one thermal insulator. The at least one wave guide may connect the micr owave generator to at least one power transfer element. The at least one wav e guide may be configured to transfer microwave energy from the microwave ge nerator to a refractory assembly. The melter assembly may comprise the refra ctory assembly and the at least one power transfer element connected to the refractory assembly. The refractory assembly may comprise at least one absor ption element configured to transfer microwave energy, received from the at least one power transition element, into heat energy. The at least one therm al insulator may be configured to allow the microwaves to penetrate to the a t least one absorption element.
