The process of spheroidization of iron Spheroidization is to introduce the cast of a certain chemical composition of small additions mostly in the form of Magnesium alloy FeSiMg along with other elements, such as RE, Ce, Ca and Al in some cases. This process changes the structure and crystallization of graphite cast iron ball to produce a casting with significantly better properties. The most commonly used methods spheroidization are: flooding, Sandwich, Tandish, Inmold and PE - using cored wire.

Depending on the method, type and quality of the mortar magnesium yield varies from 30 to 80%, with the addition of mortar in a row 1-1,6% Chemical composition and its importance Although the main purpose is to bring mortar to crystallize graphite ball, but this particular Nodulizers differ in terms of outcomes, which are usually a consequence of treatment modification, especially in terms of impact on the propensity of iron to the hard spots and the number of graphite spheroids in the unit vol.

The content of elements in our mortars are chosen so as to enable the maximum number of partial spheroids, as well as the opportunity to receive direct-cast ferritic structure. Calcium is helpful in controlling the rate of reaction of magnesium during the treatment, the low aluminum content of less than 1% to minimize problems of punctures in the wet form. To allow a homogeneous structure of the cast and the minimum separation of the components in the mortar and to eliminate the secondary oxidation of the metal in a mortar restricted magnesium oxide content below 0.6%. Titanium content is limited to 0.5% and deliberately reduced the magnesium content in the mortar, while a special technique of casting thin films results in better and more uniform distribution of phases in sferoidyzatorze Mg2Si. Uniformity achieved by this chemical allows the repeatability of the process, ensures a high yield of magnesium and the vehemence of the reaction decreases. Spheroidyzator MG5 + RE is designed for use by Sandwich and Tandish in small tanks or by Inmold the silicon content in iron at a level between 0.5% and 1.5% sulfur to 0.025%. Reduced magnesium content makes it a better digestibility and less smoke. Addition of rare earth elements removes harmful elements desferoidyzujących and pollutants from lower quality scrap.

RE Spheroidyzator MG8 high strength, for cast iron in larger tanks, or in conditions of high carbon content, making it difficult dissolution of magnesium. Designed for both spheroidization in vats and by Inmold, the silicon content in iron at levels from 1.5% to 1.8%, and sulfur within 0,025-0,04%. Higher levels of magnesium and rare earth elements can melt ductile iron, inferior quality of steel scrap and in the process żeliwiakowym. Granulation 1-10mm for smaller tanks and a 5-35mm for large vat, packaging and BigBags 1000kg and 25kg bags.
