The Annual Production of 180 Million Tons of Plate Plant
Abstract：This design is the annual production of 180 million tons of plate plant. Through the research of plate market to introduce the development of the plate, analyze the plate market demand, and direct the current state of technology to develop a reasonable outline of the products and metal balance sheet. Typical product Q345 (40mm × 4050mm ×actual length )steel-based, to determine the typical products of the process, to determine the mill arrangement of workshop equipment selection, and to develop typical products and reasonable reduction procedures to calculate the rolling force parameters, such as: rolling force calculation, the calculation of the deformation resistance and transmission torque calculation. The check rolls intensity and calculate the capacity of the motor. To determine workshop work systems and working hours, calculated the annual production of the mill, according to the typical product of the process and the size of the rolling determine workshop layout, such as device spacing, warehouse area, and draw a plan of the workshop floor . The analysis of the economic indicators of the workshop. And to take effective environmental protection measures.
Keywords: plate workshop; outline; metal balance sheets; rolling force; deformation resistance; drive torque
