Delivering effective ladle metallurgy treatment through our special combination of several fluorine compounds that are chemically engineered with alumina, DR46 is a premium performance slag conditioner.

Each product is chemically engineered to rapidly form a highly basic and fluid slag that absorbs impurities such as sulfur and products of steel deoxidation. This ladle refining treatment helps create a steel product with low inclusion levels and, within specification, to maximize castability, productivity and product quality. Our Synthetic Slags are produced with an engineered balance of premelted fluxes to increase the lime/slag melting rate and control the final slag fluidity.

Summary of the Synthetic Cryolite：

The object of the invention is to: with Al 2o 3for adding a small amount of iron ore in the waste resistant material of principal constituent, preparation becomes aluminium matter dissolving agent, and use is in converter smelting, for optimizing the extremely significant economic benefit of having recycled of steelworks solid waste rubbish.

The object of the present invention is achieved like this: a kind of production technique of composite slag melting agent for steelmaking, and the 120 tons of converter production lines of take are example, implement step by step;

Preparation of raw material:

1) get discarded refractory materials, after removing the raw material of industrial refuse and iron content, be cooled to 0.5-30 ℃, be placed in the PC0606 jaw crusher, be crushed to the particle of 5-50mm, then be placed in the Raymond mill mill of 4R3216, be processed into the following powder of 3.0mm, standby; The Al of discarded refractory materials wherein 2o 3content is 71%;

2) get the following iron ore of 3.0mm standby, wherein Fe 3o 4content is 68%;
