How to evaluate the quality of the nodulizer?
There are several common judgment criteria, 
remember to click the love on the right side of the screen to collect it:
(1) The affinity of spheroidizing elements with elements such as 
sulfur and oxygen in molten iron. 
(2) The ability of spheroidizing elements to change 
the shape of graphite from flake to spherical.
(3) The density and boiling point of the nodulizer are lower than 
those of the molten iron. 
The low density can automatically float in the molten iron, 
and the boiling point is lower than 
the processing temperature of the molten iron. 
Magnesium can be converted into a gaseous state 
at the processing temperature, and has a self-stirring effect, 
thereby improving the spheroidization effect.
(4) The magnesium oxide content in the nodulizer is about 
10% of the magnesium content.
(5) The nodulizer is dense, without segregation, 
no shrinkage porosity, and no pulverization.
(6) The particle size distribution of the nodularizing agent is uniform, 
no powdered alloy, 
and obtuse-angle and deformable particles are better.
(7) The composition fluctuation of different batches of 
nodulizer should be small.
We Nanjing Dyfeng can customize the production of 
alloy products such as nodularizing agent and inoculant 
according to the standards required by customers.
