Modification of iron

Modifiers affect the increasing quantity and reducing the size of crystallizing phases in cast iron, which contributes to the improvement of mechanical, physical and commercial castings. Presented modifiers based on FeSi are characterized by a stable and reproducible chemical composition, low melting point, good graining. The recommended allowance is 1 to 3 kg per 1 ton of metal. Provided that the selection of the appropriate type of modifier and control the basic parameters of the melt, these rates are adequate and the expected degree of modification of cast iron, low cost process, and effectively counteract zabieleniom.

FEROMOD B6

This is a special method produced a homogeneous calcium alloy with a bar on a carrier with a strong żelazokrzemowym zarodkotwórczym intentional act. Is a mortar with a much higher efficiency than traditional modifiers based on ferro-silicon, moreover, to offset the adverse effect the properties of pollutants from lower quality scrap. The use of this alloy allows for greater certainty and consistency modification process, better control of volume and sustain zabielenia modification effect in the long run. B6 mortar is used for larger castings with increased wall thickness, to modify in large vats, for a longer period of flooding and at slower solidification. Intentionally reduced silicon content in the modifier, reduced by more than 25 ° C, the liquidus temperature to below 1300 ° C. This is of great importance in the decrease of temperature and modifying the kinetics of dissolution of the inoculant.

FEROMOD B10

It is intended both to stop premodyfikacji and secondary modifications. Premodyfikacja is a process during which, the active component is added - modifier for the iron in the melting process, in order to improve their final properties. Application premodyfikatora B10 generates large quantities of graphite fixed embryos, which are still active after the process of spheroidization and secondary modifications. Application premodyfikatora also allows reducing additive sferoidyzatorów about 25-40%, thus reducing the slag MgO and Mg2O, resulting tendency to shrink and slag defects (inclusions).

Modifiers S75 and C30

They are designed to be modified by the EP, having the form of cored wire - it is a powder enclosed in a steel coated, supplied in rolls and adapted to the feeding equipment. Characterized by the dimensional stability and chemical composition and high concentration of reagent. Guarantee high accuracy and repeatability of the process, low emissions and a significant increase assimilate reagent thus its higher efficiency. C30 alloy wire can also be used for deoxidation and desulfurization of metal.

FEROMOD SR8 and Z05

These are some of the most advanced alloys based on the presence of the modifier or a combination of strontium zirconium, cerium and calcium. The operation of these alloys is to match krystalograficznym sulphides or sulphide strontium zirconium graphite phase, which allows for more than twice higher degree of modification, with the same percentage of mortar additive, as in the case of standard modifiers.

Transport and storage

Modifiers are packed loose in 25 kg bags and shipped in bulk packages at 1000kg. However, modifiers in the form of wire PE are delivered on steel racks in the horizontal and vertical rolls weighing from 1 to 1.4 tonnes. The whole is protected by a foil or PP fabric from moisture and dirt. Storage of these materials should be done in a dry place, preferably in a closed, heated and ventilated warehouse, humidity and pollution can cause harmful side effects and reduce the performance of the modifier. Packaging always have a clear indication as to the type of material and batch number, will determine the composition, proper use and expiry date of the goods.
