In 2007.10, Shanghai Xinzhong supplied 3 sets of 4100mm wide-thick plate CNC torch cutting machine for BaoTou Steel Ltd. The most difference from continuous casting product torch cutting machine is that this machine is of more strict positioning and cutting precision, the section quality need is extremely high, there can not be two guns connecting mark, and it has automatic compensation function while high temperature cutting (200℃). Based on many years torch cutting experience and mature electric control design system, Shanghai Xinzhong solved above problem completely. It got user's high praise and the user purchased more 3 sets on the basis of supplied 3 sets.

Main technical features:

(1) Quick and continuous scanning function. The TCM is equipped with high speed industrial camera which can scan the plate outline quickly and continuously, compared with laser polygonal lattice scanning, it's of higher accuracy and quicker speed, it can ensure the displayed plate steel outline on the screen is completely same with plate actual outline.
(2) Servo speed adjusting function. It adopts servo speed adjusting method to control the cutting machine walking system and cutting gun walking system, which ensured cut-to-length accuracy and increased one order of magnitude than continuous casting product TCM.
(3) It has the functions of automatic feeding, automatic cutting, automatic sampling, automatic scrap edge cutting and automatic scrap edge breaking off.
(4) While automatic sampling, it can adjust the cutting oxygen feeding pressure automatically according to different sampling position to ensure the punching function of cutting nozzle.
(5) Steel plate size temperature making up function. When the plate temperature is higher than room temperature, system will detect the plate actual temperature and making up the temperature for plate size to ensure the cold plate size accuracy after hot plate cutting.
