Abstract

PURPOSE: To obtain sufficient strength and economical manufacturing cost and minimize the downpull by selecting the entrance angle of the bottom of a gate and length of a lip within a given value.
CONSTITUTION: The form and dimension of the bottom of a sliding gate 1 are composed of entrance angle α=38°W50° and lip length L/L0=0.26W0.72. Under these conditions economical requirements for the structural strength are satisfied and the downpull can be reduced, (where the entrance angle: angle which the straight line passing the lower end of the lip makes to the horizon when the bottom plate of the gate is remolded by a circular arc with a radius of r at the rear part, L0: length of the lip when the inclination angle of the bottom plate is 0°).
