Product description
Refining agent is a new generation of steelmaking auxiliary material developed by our company to meet the requirements of low-sulfur steel. It is made by melting a variety of materials at high temperature in an electric furnace to produce aluminate minerals mainly 7AIO and 12CaO, with a content of more than 90% and an activity coefficient greater than 70. This product has fast melting, reactive
It has high stability, fast slagging speed, early appearance of white slag, good fluidity after melting, and can absorb a large amount of deoxygenation and desulfurization products in the molten steel, shorten the refining time, and reduce the cost of steelmaking, thereby reducing the content of the molten steel. Harmful impurities, the purpose of purifying the components of molten steel.
Usage method of drainage agent
1. Add it with the steel flow during tapping.
2. Add 2/3 to the bottom of the bag in advance, and add the rest with the steel flow.
3. Add metered amount at the refining furnace position.
4. The amount of steel added is 3-8kg per ton.
5. Can be added with lime
