In the case to introduce the bottom blowing method under the trough type continuous steelmaking furnace, wave motion of steel bath should be suppressed. To solve this problem, water model equipment has been used to examine the wave motion in the range of shallow water waves. Basic results obtained are as follows. (1) Frequency of the induced wave is mainly affected by the bath depth, and along with the increase of the bath length this frequency is kept in a certain range by increasing the node number of the wave. (2) In the transition range of the node number, wave motion can be weakened. (3) To suppress the wave motion it is very effective to locate each bottom blowing nozzle at the distance from transition range to the wall obtained in one nozzle test and put the nearest nozzle from the wall at the half distance of transition range. (4) The node number and transition range can be represented on the non-dimensional diagram of the bath depth to the ratio between distances from nozzle position to both side walls.
