Passivated Magnesium Powder

Introduction

Passivated Magnesium Powder is used for desulphuration and deoxidation in production of fine steel, bringing the sulfur element of fine steel to be less that 0.004%. As a dehydrant, it is not replaceable to improve fine steel quality, exploitation, In production of ductile cast iron. it can be a nodulizer in place of middle alloy among iron-silicon-magnesium.

For oil, it can resume or accelerate the speed of the pressure drilling hole and oil well. Passivation spherical magnesium powder is an effective dehydrant and incendiary agent for chemical and war industries. Besides used as a magnesium alloy powder, it is also a kind of metallurgical materials.

As the desulphuration agent for smelting steel and iron, passivation spherical magnesium powder has been widely used in developed countries. It is necessary for steel and iron enterprises to produce qualified and special type steel. The advantages of desulphuration are: less consumption, short time processing, fast reaction, little dropping of molten iron temperature. little sinter, good effect of desulphuration and deep desulphuration.

Physical and Chemical Property and technique Standard

1. The Passivated Magnesium Powder looks grey and white, and the granule shape is roundness or unequal roundness.

2. The burning point of passivation magnesium powder is between 560℃-600℃.

3. The fire retardant time of passivation magnesium powder is not less than 15 seconds at 1000℃.

4. The passivation magnesium powder should not contain impurity and agglomeration, but there can be a little passivation layer powder.

Features

Passivated Magnesium Powder is flammable and explosive, and brings high temperature and glaring light when burning. Therefore, magnesium powder is widely used in such scientific areas as military and aviation industries, The chemical performance of magnesium is very active, which is mostly used in metallurgical industry. Magnesium powder can server as desulfurizer or cleaning agent for steel-making industry and casting of non-ferrous metals, and reducer for production of rare metal. In chemical industry, magnesium powder can be used as dehydrant for organic compound or to directly make organic compound of magnesium. In recent years, magnesium powder has been mostly used in spaying, coating, anti-corrosion, monocrystalline silicon, polycrystalline silicon, and casting of metallurgical powder as well.

Main purpose

In the production of high-quality steel, passivated spherical metal magnesium powder is used for removal and deoxidation, so that the SuFe element in the steel is less than 0.004%. Using Fe-Si-Mg master alloy instead of Fe-Si-Mg master alloy as nodularizing agent for ductile iron is irreplaceable compared with other paint stripping methods in producing high-quality steel. Restoring and accelerating pressure drilling and wells into late-stage velocity for the oil industry. In the chemical industry, the military industry is an effective dehydrating agent and oxidant, and it is also a magnesium alloy powder metallurgy material.

Application

Magnesium powder in the military-industrial and aerospace industries in the field of science and technology have a wide range, for the production of a reducing agent, flash powder, lead alloy, metallurgy to sulfur agent, organic synthesis, lighting agent, fireworks, steel desulfurization, arms, automotive, petroleum, chemical, pharmaceutical, metallurgical and other industries.
