The disadvantages are that the measurement precision is influenced by the deflection(level measurement), swing, material, diameter of steel wires ,and the workers must have a good operation technique .

Research on Hot State of Mould Copper Plate with High Casting Speed Sun Ligen1, a, Li Huirong1, b, Zhang Jiaquan2,c 1School of Metallurgical and Energy, HEUU, Tangshan 063009, China 2 School of Metallurgical and Ecological Engineering, USTB, Beijing 100083, China asunligen@heuu.edu.cn, blihuirong@heuu.edu.cn, cjqzhang@ustb.edu.cn Keywords: mould copper plate; high casting speed; thermal state; equivalent strain field Abstract：High casting speed has a great influence to thermal state and strain/stress field of the mould copper plate.
Introduction Casting speed is one of the key technical parameters for continuous casting.
The major assumptions are as follows: 1) Casting speed and Casting temperature are constant value; 2) Casting speed with neglected thermal conduction in casting direction; 3) Small deformation of the mould plates and steel shell with only material nonlinearity; 4) The influence of the thermal convection of the molten steel at the solidifying front is described by equivalent thermal conductivities according to the local temperature; 5) Thermo-elastic-plastic model is adopted for the steel shell, and the thermo-elastic model is used for the copper plates.
