“…where L is the distance between P and the intersection point for the axis c Z and the object plane; 1 N are known, the boundary point can be calculated from (8). And according to values of boundary point in the image coordinate system and geodetic coordinate system at different level height, these parameters can be solved.…”

A CCD system was designed to detect the molten steel level in the strip casting process. According to the image computing method, camera mathematic model of the molten steel level detection was established. Then an experiment was carried out to calibrate the model parameters and the precision of the mathematic model was tested. The result illustrates that the camera mathematic model and calibrate method of the molten steel level are feasible, which show high levels of precision and can be applied in the industrial line for the strip casting.

“…[1][2][3] During the production, the strip quality depends closely on the molten steel level because it affects the molten steel solidification rate at the sump. [4] Molten steel overflow may damage the expensive twin roll or surrounding equipment, and an insufficient amount of molten steel at the sump may cut the strip off.…”

“…The principal problems on a smelting furnace in metalworking are caused by high temperatures and the gases produced by the slag. For the industry, the casting process is important because the product quality depends on it [1], if the process is slow. Then the molten steel will cool and if it is a quick casting then it will provoke turbulences, its effect produces corrosion and erosion in the refractory [2].…”

Nowadays, manufacturing processes are carried out at speeds that they themselves demand and subject to rigorous standards to maintain the quality of materials. An important step to define the quality of products in metalworking is the casting process, which principal focus is seeking control and monitoring of properties of materials. Nevertheless, it is not easy due to the high temperatures and gas produced in the vessel. Although some researchers have been attempting to solve these problems, it is difficult to carry out due to hard conditions. This article proposes the analysis of the surface of the liquid metal, that is, the slag on the surface, which is considered as connected spaces characterized by the topology of their discrete surface. These spaces are described through Fast Fourier Transform, associating changes of intensities to the frequency domain and obtaining main features of these frequencies, these features are used to define an enveloping shape that represents the liquid metal. Finally, the results obtained are presented, which, according to them shows that it is possible to characterize the slag, and by which it is possible to spatially locate the molten metal liquid in the refractory. Therefore, this research serves as the basis for the development of new algorithms for level detection and measurement, preventing overflows and damage to refractories.
