- 1. Name of Product : Pre-molten Ca-Al combined desulphurizer
- 2. Type of Product : Special steel 09 GL-50 GL-80
- 3. Applications :
- Being used in RH&LF to refine the molten steel, it can get
rid of S, O and contaminationis and improve the fluidity of
the slag. Especially the grade special steel 09, because of its
low content of TiO2, SiO2 and F, this product has good effect
during refinery of special steel.

- 1. Name of Product : Reducing agent for molten slag
- 2. Type of Product : YH-A YH-B
- 3. Applications :
- This product is an agent for deoxidizer and slagging.
It can improve the fluidity of the molten slag produced
in refining process, make Al2O3-seperation easier, prevent
from the defuse of the impurities in the molten slag to
guarantee producing high quality steel. Furthermore, when
there is difficulty for the deoxized molten steel to be
deoxized again in the next steps, this product can be
replace the expensive metal aluminium as the deoxidizer
to cut the producing cost.

- 1. Name of Product : Deoxidizer and Desulfurization Agent
- 2. Type of Product : GZA-20 GZA-30
- 3. Applications :
- Being used in the process of the refinery out of the furnace,
restraining the emerge of FeO, promoting to get rid of O, S,
adjusting the viscosity of the cinder, improving the fluidity
of the cinder, preventing the temperature on the surface of the
molten steel going down. Because of its low price, this product
can cut down the producing cost greatly.
