The invention discloses a ferronickel refining system which comprises a ferronickel tank, a melt feeding device, a ferronickel tank moving device, an impurity removal reagent adding device, a top oxygen blower, a bottom gas blower, a temperature detector, a sampling device and a slag removing device, wherein the top of the ferronickel tank is provided with an opening, and the bottom is provided with a gas injection port; the melt feeding device is connected with the opening of the ferronickel tank; the ferronickel tank is arranged on the ferronickel tank moving device; the impurity removal reagent adding device is connected with the opening of the ferronickel tank and used for adding an impurity removal reagent into the ferronickel tank; the top oxygen blower comprises an oxygen tank and an oxygen lance connected with the lower part of the oxygen tank, and the oxygen lance is inserted from the opening to the inside of the ferronickel tank; and the bottom gas blower is connected with the gas injection port, so that a gas is injected into the ferronickel tank from the bottom. According to the ferronickel refining system disclosed by the invention, devulcanization and dephosphorization can be implemented in one reaction vessel on the premise of satisfying the strict requirement of stainless steel production for the impurity content in the ferronickel; and the ferronickel refiningsystem disclosed by the invention has the advantages of low energy consumption and simple structure.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a ferronickel refining system. Background technique [0002] As we all know, nickel is an important alloying element in the metallurgical industry. Due to the unique properties of nickel metal, it is widely used in the production of stainless steel, special alloy steel, nickel plating, ceramic products, battery catalysts and many other fields. Nickel alloy Materials play a very important role in national economic construction and national defense military construction. [0003] With the wide application of stainless steel and special steel in the world, the supply of nickel metal, the most important element of metallurgical stainless steel and special steel, is in short supply, causing the price to soar. At present, more than 60% of the world's nickel products come from sulfide ores, and more than 60% of the world's nickel resources exist in laterite nickel ores. Ferronickel...
