This paper focus on the water distribution of secondary cooling for beam blank continuous casting process. Analysis of the influencing factors and initial determination method for important parameters of secondary cooling water, including specific water, water ratio in each secondary cooling zoon and the amount of water in outer arc, inner arc and sider at one secondary cooling zoon. After that, according to the simulation heat transfer process of the secondary cooling, to improve the secondary cooling system is given. This work provides a reference to the development of secondary cooling system.

Central Defect

Continuous casting process parameters such as casting speed, superheat, secondary cooling water flow rate have greatly affections to central defects in SWRH82B billet. These parameters were investigated by the methods of chemical content analysis and etch test for macrostructure in some steel plant of china. The results shows that the central defect of SWRH82B billet can be improved when the superheat is controlled at the range of 15~25°C, casting speed is 1.80m•min-1 and secondary cooling water flow rate is 0.72 L•kg-1.

Electromagnetic brake (EMBr) technique is adopted to reduce the turbulence of molten alloy in the slab mould in the continuous casting process, especially under high casting speed. We introduce a state-of-the-art EMBr technique by reviewing the published literature. The main objective of this paper is to give a clear view of the EMBr technique in terms of the magnet arrangement, along with their “Braking” effect to help decision-making. The EMBr system can be divided into three types, in terms of the magnet arrangement: the Local type, the Ruler type and the Multi-mode type, respectively. Both advantages and disadvantages of each type have been discussed. Further challenges are also raised.
