Determination of the carbon equivalent in structure-modified cast iron |
November 26, 1996 |
| A method for determining the carbon equivalent (C.E.) of structure modified cast iron melts, and use of this method for adjusting the composition of a structure modified cast iron melt. The method is based on the introduction of one or more pieces of iron of low carbon content into a sam |

Method for producing cast-iron, and in particular cast-iron which contains vermicular graphite |
May 26, 1987 |
| Method for producing castings from cast-iron containing structure-modifying additives. A sample from a bath of molten iron is permitted to solidify during 0.5 to 10 minutes. The temperature is recorded simultaneously by two temperature responsive means, one of which is placed in the cent |
