%X Recently,to improve the quality of seamless steel tubes,many domestic billet enterprises use skew rolling piercer with Diescher guide-disc to pierce steel billets.However,in skew rolling piercing,the guide-disc speed can't be measured directly because of the limitations in practical conditions.Therefore,an online soft measurement of the guide-disc speed has to be developed for controlling the guide-disc speed to improve the productivity and quality of steel tubes.To cope with this problem,we propose a measu...
