Manufacturing of the future has to be more flexible and versatile in order to meet the ever changing needs of the customer. Most continuous casting machines today are rather inflexible in that they are designed to cast specific types of alloys and with limited size ranges, thus suitable for the mass production paradigm. This paper reports the design and development of a modular horizontal continuous casting machine (HCCM). The aim is to have a machine that can continuously cast a variety of ferrous alloys from carbon steels, low alloy steels, stainless steels to cast irons, and with ranges of cross-sectional areas. The modular design approach and quick changing techniques are employed as the key design concept. The construction of the first prototype of the machine is completed and several field trials have been conducted. The results are promising. For carbon and low alloy steel billets, the overall structures and surface quality are good although the amount of porosities is rather large. The overall quality of stainless steel billets is better than that of carbon and low alloy steels. Adapting and setting up the machine for casting different alloys and/or different billet sizes require a little time, no more than 20 minutes.

The Cost

The system of automatic feeding of the slag-forming mixture into the mold of the continuous casting machine was investigated in this article. The necessity of using a slag-forming mixture in the process of steel production has been substantiated. The proofs are given that the consumption of the slag-forming mixture significantly affects the cost of the final product. The quality level of the final product depends on the uniformity and consistency of the mixture supply to the crystallizer. Therefore, the actual direction is the automation of the process of feeding the slag-forming mixture into the mold of the continuous casting machine. The description of the developed automatic installation, which implements the supply of slag-forming mixture, is presented. The necessity of using a sensorless electric drive for moving the trolley has been substantiated. A simulation model of a bogie electric drive with a vector control system based on sensorless determination of the angular speed of the engine has been developed. The description of the method for determining the angular speed of the motor based on the known values of phase voltages is given. The simulation of the developed electric drive system in the Matlab Simulink program, confirming the adequacy of the developed system. The introduction of a sensorless electric drive into the system for feeding the mixture into the mold of the continuous casting machine will increase the reliability of the entire system and reduce its weight and dimensions.

Steel Grades

Modern steel plants produce today a large portfolio of various steel grades, many for end-uses demanding high quality. In order to utilize the maximum productivity of the continuous-casting machine, it is sometimes necessary to cast steel grades with different chemical compositions in one sequence. It is important, therefore, to know the possibilities of a specific continuous-casting machine to make the Intermix connections as short as possible. Any interference with established procedures may, however, have a negative impact on the cleanliness of the cast steel. Using physical and numerical simulation tools, it was found that reducing the steel level in the tundish during the exchange of ladles makes it possible to shorten the transition zone. However, when the steel level is reduced, the flow of steel is impaired, which can have a negative effect on the cleanliness of the cast steel and, in extreme cases, may even lead to entrapment of slag in the mold. The cleanliness of cast steel was evaluated using one of the most advanced tools for automatic steel cleanliness evaluation, AZtecFeature (Oxford Instruments, Abingdon, UK), which enables determination of the type, size, distribution, and shape, as well as the chemical composition, of individual types of non-metal inclusions.
