Design Notes

The design for the annual production of 180 million tons of plate plant, plate market research, the development of the plate, the plate market demand, and the current state of technology, to develop aa reasonable outline of the products and metal balance sheet. Typical product Q235 (10mm × 1700mm × 6000mm, 25mm × 1000mm × 6000mm, 4010mm × 1450mm × 4000mm) steel-based, to determine the typical products of the process, to determine the 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 the appropriate choice of rolls and 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 the workshop floor plan . Analysis of the economic indicators of the workshop. And to take effective environmental protection measures, such as the greening of the workshop, waste gas and waste recycling and so on.

Keywords: plate workshop, outline, metal balance sheets, rolling force, deformation resistance, drive torque
