【正文】 ty of 600,000 t/aSpecialty：Metal Material EngineeringName：Instructor：AbstractThis is the technology design for producing sixhundred thounsands tons of hot rolled bar workshop per year. The size of the product is between Φ16 and Φ36 with the major steel grade of the carbon structural steel ,the carbon constructional quality steel or the low alloyed we carry out national standard during the production .According to the size of product we use the concast billets with the size of 150mm150mm10000mm for the raw material and the Walking Beam Heating Furnace . We use continuous rolling technology ，there is 18 mill in mon ,6 for roughing mill ,6 for medium mill ,6 for finishing mill . The largest end mill speed is about 13m/s .In the production of steel rolling we use the pass system of square－square－ellipse－ circle－ellipse－circle－ellipse－circle －ellipse－circle－ellipse －circle－ellipse－circle －ellipse －circle－ellipse－circle．Key words：process design，hot rolled ribbed bar，shape steel ，concast billet，fully continuous rolling3 第 3 頁(yè)目錄1 緒論
