Product Information:

Silicon Carbide: Model JDX-90

Size range: electric furnace (0.5-1mm Or 1-5mm)

Cupola (40-90mm)

Product features: JDX-90 uses petroleum coke as the basic raw material, the silicon-carbon ratio is uniform and stable, effectively reducing the production cost, the decomposition speed in hot metal is fast, and the graphite core is continuously added to the hot metal.

Application direction: nodular cast iron (valve fittings, agricultural machinery, engineering machinery, automobile support steering knuckle, etc.), vermilion cast iron (engine cylinder head, hydraulic valve body), gray cast iron (brake disc, machine tool castings, engine cylinder head).

Product Overview:

1.Jiuding SiC is a strong deoxidizer to purify the liquid iron, improve the casting quality and reduce the cost.

2.Jiuding SiC has stable carbon-silicon ratio,with low content of Al,P,and inert gas.

3.Effectively control the corrosion of iron oxide(FeO to the furnace lining,and avoid producing fayalite FeO-SiO2)to extend the life of furnace lining.

4.Long-acting inoculation effect:there is a SiO2 cover on the surface of SiC crystal which could slow down the nucleaus releasing speed,and result in reducing tendency of cementite and chill,optimizing graphite morphology and stabilizing machinability of the casting.

5.In ductile iron casting,the deoxidation pre-treatment by Jiuding SiC could reduce the ablation and oxidation of Mg, which could save the nodulizer by 10%and prevent chill.

6.In gray iron casting,SiC in charge could prevent the precipitation of carbide,delay the inoculation fading,and prevent chill.

7.Jiuding SiC is made of petroleum coke with centralized and controllable particle size distribution,and easy to use.

How to use:

JDX-90 1-5mm is mainly used in induction furnaces, with a recommended addition of 0.8-1.2%.

JDX-90 0.5-1mm is mainly used for in-package pretreatment, and it is recommended to add 0.1-0.3%.

JDX-90 40-90mm is mainly used for cupola, 0.8-1.5% of batch material.
