Baffle-plate of stepless adjustable length is designed on the base of the old multistage length baffle plate.

Based on the process control and requirement of the continuous casting machine(CCM),with the PLC control system,full automatic cntrol of cut-to-length was realized by combining cutting technology of the flames cutter machine with manipulating the imagines to length of steel billet by untouched-mode.

The technology of using image analysis and pattern recognition to implement the non-touching automatic billet cut-to-length is mainly introduced.

5 continuous caster at the Steelworks by heavier interference of flame cutting to infrared non-contact cut-to-length system and not high enough cutting precision,the PLC cut-to-length system was developed,satisfactorily solving the cut-to-length problem.

On the basis of the studies on the effect of hot-centering machine on the production of hot-rolled seamless tubes and the advantages and disadvantages of several types of the present hot-centering machine, A new type of hot-centering machine was designed by ourselves which could realize the length and centre and could centre simultaneously at the head and the end.
