Stream inoculation is generally practiced where pouring is done through an autopour device so that the pouring rate is more or less constant. A stream inoculator is then used to add inoculant to the stream of the metal at a constant rate. If you can device a method to ensure that the flow of metal andd of the inoculant is constant then stream inoculation becomes effective. Size varies between 0-0.5 mm depending upon the metal flow. Also for stream inoculation, the gating system design needs to be good so that slag formed during inoculant addition does not go inside the mould. For non-automated pouring lines this is not a very attractive alternative.
