THE “COPPER DEMON”

When German miners exploring the Ore Mountains in the 17th century came across “a pale brownish-red rock,” they thought they knew exactly what they’d found: a new copper ore. What they’d really found was a previously unknown nickel ore, which is now known as “nickel arsenide” or “niccolite.”

 

The miners tried to extract the copper, but couldn’t get it done. “The frustrated miners blamed Nickel, a mischievous demon in German mythology, for playing a prank on them and began calling the ore kupfernickel, (which translates to) ‘copper demon.’”

 

A hundred or so years later, Baron Axel Fredrik Cronstedt, a Swedish alchemist, was able to separate the nickel from the ore and isolate it as a new element. He dropped the “kupfer” and used what was left as the name for now number 28 on the periodic table of the elements: nickel.

 

Metal nickel is a silver-white metal with good ductility and corrosion resistance. is also widely used in industry. Ferronickel is an iron-nickel alloy with a nickel content of 20%-60%. Ferronickel is mainly used in the production of stainless steel and special steel. Ferronickel can provide certain nickel elements to steel to improve the properties of the steel.

 

THE ROLE OF METAL NICKEL IN STEEL

 

Because metal nickel has excellent corrosion resistance and high temperature stability, it is often added to stainless steel as an additive to improve its corrosion resistance. In addition, nickel can also improve the strength and hardness of steel and enhance its wear resistance.

 

Nickel metal has a slight graphitizing effect in cast iron, stabilizing pearlite and reducing ferrite content. Nickel in cast iron therefore contributes to a uniform and integrated structure and good properties.Adding a small amount of nickel to cast iron will lead to the formation of fine pearlite, and when the nickel content is high, martensite and austenite will be formed.Fine and stable pearlite gives cast iron good processability and hardness. Therefore, nickel-added iron castings can be used to manufacture castings in the automotive industry.

THE ROLE OF NICKEL METAL IN STEEL AND ANALYSIS OF INFLUENCING FACTORS

 

Improve the strength and corrosion resistance of steel:

Nickel can increase the strength of steel and enhance its corrosion resistance in corrosive environments such as acids and alkalis.

Improve low temperature toughness:

 Nickel can reduce the critical cooling rate of steel, improve the hardenability of steel, and keep the austenite structure of steel at low temperatures.

Refining grains:

 Metallic nickel can refine ferrite grains and improve the plasticity and toughness of steel.

Improve fatigue performance:

 Steel containing metallic nickel improves fatigue properties and reduces susceptibility to notches

 

NICKEL METAL PRODUCE PROCESS

There are two main types of metal nickel produced Metallurgy, the first is the fire method and the second is the wet method. According to the different main nickel-containing minerals in the world, namely nickel-containing copper sulfide and copper oxide, the smelting and processing methods are also different. The nickel metal produced around the world mainly includes metallic nickel, ferronickel and other nickel products.

 

Nickel-containing sulfide ores are currently mainly processed by fire methods. Generally, the concentrate is roasted first, then smelted in an electric furnace, copper-nickel-sulfur blowing is performed, and finally nickel frame electrolysis is performed to obtain metallic nickel.

Oxidized ore is also called nickel-bearing laterite ore. There are generally three processing methods for this. The first is the traditional PKEF process, the second is the Japanese Dajiangshan rotary kiln direct reduction method, and the third is the blast furnace smelting process..
