Nodulizer, well known as nodularizer, is a metal or alloy used to produce graphite cast iron. The most widely used nodulizing agent is rare earth ferro silicon magnesium (ReFeSiMg).
Ferro Silicon Magnesium Composition
FeSiMgRe3: Re: 2-4%, Mg:7-9%, Ca:2-3.5%, Si:44%
The additive that crystallizes the graphite in cast iron into pellets is called “spheroidizing agent”. The main components of “spheroidizing agent” are magnesium, cerium, calcium and other spheroidizing elements.
Spheroidizing agent particle size :5-30mm(can also be processed according to customer requirements), gray black solid thickness less than 100mm.
Characteristics of spheroidizing agent: strong spheroidizing ability, stable composition, stable reaction, no decline. Composition and particle size can be precisely controlled as required.
Spheroidizing agent packaging :50kg bag plus ton bag, or packaging according to customer requirements.
Ferro Silicon Magnesium Uses
All kinds of rare earth silicon magnesium alloy spheroidizing agents used in nodular cast iron can be used for spheroidizing, desulfurizing and degassing after adding hot metal, and can improve the purity of casting water. It can also react with low melting point impurities such as arsenic, zinc and lead. The formation of low melting point compounds insoluble in iron to eliminate these impurities, and can play a role in preventing interfering elements from destroying spheroidization.
The spherical graphite in nodular cast iron is formed by the spheroidization of hot iron, which makes its strength much higher than gray cast iron, toughness better than malleable cast iron, while maintaining a series of advantages of gray cast iron. However, the “spheroidizing agent” used in nodular cast iron castings can increase the tendency of “white opening” and hardening of microstructure in the weld, and cause cracks in the weld and heat affected zone (especially in the fusion zone).
ZXferroalloy Specilize in Ferro Silicon Nodulizer
(1) Strong spheroidization ability
(2) Abundant resources, low prices,
(3) Strong adaptability to various components of hot metal (such as eutectic degree, sulfur content, spheroidizing resistance elements, alloying elements) and temperature
(4) Easy to melt, good kinetic conditions of spheroidization reaction, relatively stable reaction, easy removal of reaction products, less dosage, lower temperature, good spheroidization process;
The Adding Method of Ferrosilicon Magnesium
The factors influencing the quality of spheroidizing agent include composition, particle size, shape, density, MGO content, etc.
(1) spheroidizing agent composition should reach the required content
(2) spheroidizing agent powder, the size of the alloy can not meet the requirements
(3) The density of spheroidizing agent fluctuates greatly, part of the spheroidizing agent floats fast, the reaction is too intense, and the safety is not guaranteed
(4) The content of MGO is too high, the spheroidizing treatment is not good, and the amount of spheroidizing agent is too large
(5) Rapid decline after spheroidization.
The spheroidizing agent produced by Zhenxin Metallurgy can be customized strictly according to customer requirements from content to particle size, so as to avoid affecting the quality of cast iron due to spheroidizing agent.
Ferro Silicon Magnesium Prices
“Ferroalloy Online” 2023-4-27: As the May 1st holiday approaches, the wait-and-see sentiment in the rare earth alloy market is getting stronger. The willingness to purchase terminals before the festival is relatively average, and the quotations of alloy manufacturers mostly maintain high prices. Today, the mainstream quotations of rare earth silicon 30# one-step method in Inner Mongolia 11,500-12,000 yuan/ton, 30# two-step method mainstream quotation 13,500-14,500 yuan/ton cash including tax leaves the factory; rare earth magnesium 3-8 mainstream quotation 10,000-11,500 yuan/ton, 5-8 mainstream quotation 10,500-12,000 yuan/ton Cash ex works including tax.
Yesterday, the quotations of magnesium ingot factories were mostly at 24,000 yuan/ton in spot exchange, and the high-level transactions have not yet been launched in batches. The recent demand has not improved significantly, and there is no new news on environmental protection policies. The price of magnesium continues to rise sharply or it may be difficult. It is necessary to continue to pay attention to the stocking situation before the May Day.
Ferrosilicon Magnesium Prices Outlook
“Ferroalloy Online” 2023-4-27: Quotations in the rare earth magnesium market mostly remain high, but downstream demand is poor, procurement is extremely cautious, and the actual transaction volume is small. Most dealers of rare earth silicon magnesium magnesium said that there are few new orders in the near future and the overall transaction pace is slow.
Today, the quotation of rare earth magnesium 3-8 ex-factory tax in Inner Mongolia is 10,000-10,500 yuan/ton, and the quotation of 5-8 ex-factory tax is 10,500-11,000 yuan/ton; the quotation of rare earth magnesium 3-8 in Jiangsu area is 11,000-11,500 yuan/ton Yuan/ton, 5-8 ex-factory price including tax is 11500-12000 yuan/ton.
From January to April 2023 is incompletely counted (by region) totaling about 117,358 tons.
