Graphitized Recarburizer

Strong recarburization effect, improve performance

Carbon increase index★★★★★

Applying strictly selected high quality Graphitize as raw material

Graphitized recarburizer was produced through continuous high temperature furnace calcination, high temperature purification, crushing, drying, screening and other processes. It has high purity, good particle morphology and graphitized crystal structure, not only can increase the carbon content, but also promotes the inoculation nucleation of cast iron, improves graphite refinement, increases the number of graphite balls, and improves the mechanical properties and processing properties of the material.

High quality performance

1、Increase carbon content: significantly increase the amount of nodular graphite in nodular cast iron during inoculation process, promote graphitization.

2、Improve graphite refining: increase the graphite nucleus of melted iron , refine the graphite ball to make it more evenly distributed in the matrix.

3、Improve performance: Improve the mechanical properties and processing properties of the material.

4、Cost saving: It can reduce the use of pig iron I, increase the use amount of scrap steel, and save raw material costs.

Laboratory Testing

1、Furnace charging method. It can be added to the furnace according to the ratio or carbon equivalent requirements, melting in medium frequency electric furnace, the recovery rate can reach more than 95%.

2、If applying low-temperature recarburizing process, that is only part of the furnace charing is melted. When the molten iron temperature is low, all the recarburizer is added to the molten iron at one time. At the same time, using the solid charge pressed it into the molten iron to prevent it from exposing the liquid iron surface.

3、If the amount of carbon is insufficient in the melted liquid iron to adjust the carbon propotion, firstly cleaning the slag in the furnace, and then add the recarburizer, by heating the liquid iron, electromagnetic stirring or artificial stirring to melt and absorb the carbon. The recovery rate can be about 90%.
