Lump lime of KFN

Lump lime for the production of high-grade steel

In the production of quality steel, our industrial customers bank on our specially processed lump lime. It has been used for decades to remove impurities from high-grade steel types.

For high-grade steel

Many of our good ideas have their origins from our intensive dialogue with our customers. This is also true for our sieved, very pure fine lump lime nekafer® 15. Used as an alkaline aggregate, this highly pure calcium oxide from KFN serves to remove impurities from molten steel. Lump lime binds sulphur, phosphorus and manganese, inter alia.

You will receive our lump lime exactly in the quantity you need. Usually, we ship nekafer® 15 to you in bulk and via rail. However, we are also prepared for your individual shipping and transport wishes, to include packaging and lot size.

The KFN lime comes from the Elggis mountain and its content of CaCO3 is naturally high: it is above 98 %.

High reactivity

With a measured t60 value of under 40 seconds, KFN offers a lime with a very fast reaction time.

Constant high quality

The consistent spread of the individual grain sizes of our white hydrated lime-products is continually monitored. Additionally, the chemical purity and the humidity of the powder are constantly checked.
