| Abstract: | Introduced in the paper are relevant processes,process data and technical measures taken for the trial operation of the Φ76mm plug mill line to produce small-sized hot-rolled mother tubes.A comparison of the said mother tube with that from previous process is made to show the former's advantages in terms of cold-drawing passes,yield and yield loss when used as blank for thin-walled cold-drawn pipe.Relevant operation has proven that the employment of the Φ76mm plug pipe mill line to produce small-sized hot-rolled mother tubes for cold-drawn pipes can not only enlarge the product-mix of the mill line,but also bring about more reasonable process technology for smallsized,thin-walled cold-drawn steel pipes. |
