Abstract：All sticking breakout accidents were focused on No.1 caster in the production process for two slab casters of a domestic plant. Observation results showed that surface oscillation mark of slab produced by No.1 caster was more disordered. Therefore poor mould oscillation condition could be the main reason for sticking breakout and should be detected. A portable slab CCM oscillation detection device composed of data processing computer, data line and acceleration sensor was designed and manufactured. Also, a set of friendly interface, easy operation of the detecting system software was developed. Mould oscillation condition could be tested and correlative date could be acquired by above device and soft. The analysis report on mould oscillation frequency, oscillation amplitude, deflection, oscillation velocity, oscillation displacement and track could be formed quickly and automatically by the software. The device had the characteristics of simple load or unload, steady and reliable operation and high precision. Detection results show that mould oscillation deflection value of No.1 caster is higher than 0.6mm and the oscillation velocity curve donot conform to the sine function. Therefore, the mould oscillation device had been improved and the frequency of sticking breakout was reduced from 6 per month to 0-1 per month.
