Benefits of technology
This new combination design allows for better control over how liquid metal flows through an immersion inductor system used during casting operations without losing its effectiveness or requiring expensive maintenance. It achieves this by combining two different types of material: one made up primarily of iron oxide (iron) while another consists mostly of aluminum nitride ceramic powder mixed together. By adding these components into the magnetic field generated by electric current flow within the conductive wires inside the device's housing, it becomes possible to improve both efficiency and productivity. Overall, this innovation simplifies the process of manufacturing high quality cast products that use induction heated systems.
Problems solved by technology
This patented technical problem addressed in this patents relates to improving the efficiency and automation of electric arc furnace tapings during casting operations without causing environmental concerns such as air emissions from exhaust gases generated through combustion processes used to cool down iron scrap foundries' spent wires.

Abstract
The invention discloses a combined type pocket block based on an electromagnetic induction heating tapping technology. The combined type pocket block comprises an upper pocket block body and a lower pocket block body; an induction coil is poured and packaged in the lower pocket block body; an induction coil lead wire is led out of the bottom of the lower pocket block body, penetrates through a steel ladle bottom case and is connected with an induction heating power supply; the upper pocket block body is stacked at the top of the lower pocket block body; the upper pocket block body is in located connection with the lower pocket block body through a bulge and groove structure on the contact surface; an upper molten steel channel is formed in the upper pocket block body, and is of a frustum cone-shaped structure; the minor diameter end of the upper molten steel channel faces downwards; the height of the upper molten steel channel is less than or equal the height of a Fe-C alloy fusion layer; a lower molten steel channel is formed in the lower pocket block body; the lower molten steel channel is of a cylindrical structure and communicates with the upper molten steel channel; and the diameter of the lower molten steel channel is equal to that of the minor diameter end of the upper molten steel channel. Duty-cycle operation of the induction coil is achieved, the sizes of the molten steel channels are optimized, and the 100% automatic pouring rate is ensured.
