OPTIMIZATION OF THE SECONDARY COOLING IN A CONTINUOUS CASTING PROCESS WITH DIFFERENT OPTIMIZATION OF THE SECONDARY COOLING IN A CONTINUOUS CASTING PROCESS WITH DIFFERENT SLAB CROSS-SECTIONS

Original language description

Although the continuous casting of steel began almost 60 years ago, its production still suffers from many serious defects in the final structure. Cracks in the solidifying slab are mainly caused by variable thermal conditions and mechanical stresses. It is well known that the secondary cooling zone has an important effect on the internal and surface quality. Thus, the optimal control of the cooling intensity in secondary cooling is inevitable in order to obtain high-quality products. Nowadays, the control of the slab temperature via numerical temperature-field models is a common practice for controlling the quality of the slabs. This leads to cooling regulation according to the actual casting speed, casting temperature, cross-section of casting slab, chemical composition of steel, etc. Unfortunately, the actual practice in many steelworks is that the cooling regulation is determined as a simple linear function of the casting speed. In order to deal with this problem, the fuzzy-optimization algorithm and numerical model of the temperature field were created. Their combination can provide instructions for how to control the secondary cooling and obtain high-quality of steel. This paper mainly describes the differences between the optimal cooling of different slab cross-sections (width between 800 mm and 1600 mm, thickness between 180 mm and 250 mm). The results show that the proper setting of secondary cooling cannot be done without a consideration of all the main casting factors.
