Abstract

PURPOSE: To enable wet blasting to be performed at high efficiency by disintegrating scale effectively in the lst stage and making surface characteristic good in the 2nd stage, through selection of pressures, etc.
CONSTITUTION: A metal strip 4 is supplied from above to below in the projecting chamber 1 of the 1st stage. On the other hand, abrasive material 5 such as silica sand is projected by the pressure of luquid or by the pressure of air or other in the state of being mixed with the liquid and abrasive material 5 to the surface of the strip 4 at the pressure and distance permitting effective descaling, from blasting nozzles 6, whereby scale 11 is removed. Next, the strip 4 is sent in the projecting chamber 7 of the 2nd stage, where it moves from above to below. On the other hand, abrasive material 5 is projected at a suitable pressure and distance from blasting nozzles 10, whereby the abrasive materials having deposited and remained in the 1st stage on the surfaces of the strip 4 are removed and the surfaces of the strip 4 are smoothed.
