PURPOSE: A roll gap control method for an HCI(hot compacted iron) forming apparatus is provided to compensate a roll gap which is generated when rolls are torqued down and to determine the torque of the rolls such that the torque of the rolls can be rapidly restored. CONSTITUTION: A roll gap control method for an HCI forming apparatus comprises the steps of: calculating a real-time roll gap value by feeding back the torque of a pair of rolls in real time during HCI forming; detecting torque down using a real-time torque value; and controlling a roll gap to reduce the gap between the rolls.
