Principle of Spheroidizing Agent Production - Content of Interference Spheroidizing Elements in Metal Furnace Charge (1) The content of pig iron is relatively high, such as pig iro
(1) Strong spheroidization ability; (2) Rich in resources, low in price, and easy to melt; (3) Strong adaptability to various components (such as eutectic degree, sulfur content, c
Chromium is one of the important Strategic material. It has characteristics such as hardness, wear resistance, high temperature resistance, and corrosion resistance. The uses of Ch
Medium, low and micro carbon ferrochrome is generally made of silicochromium alloy, Chromite and lime, refined and desilicated by 1500~6000 KVA electric furnace, and operated by hi
The abundance of chromium in the crust is 0.035%, but the generated chromium ore contains high chromium. The Chromite resources in the nearly north-south fold belts on the earth ac
Adding chromium to steel can significantly improve its oxidation resistance and increase its corrosion resistance. Chromium is present in many steels with special physical and chem
Smelting with reduction electric furnace, using coke as reducing agent and silica or Bauxite as flux. The slag composition is generally SiO227-33%, MgO3 0-34%, Al2O326-30%, and Cr2
In 1821, P. Berthier heated the mixture of charcoal, chromium oxide and iron oxide in a crucible to produce ferrochrome. This method was used until 1857 when E.C. Fremy smelted Tas
Chromium iron is divided into high carbon chromium iron according to different carbon contents, including charging grade chromium iron (C ≤ 10%), medium carbon chromium iron (C ≤ 4
An iron alloy mainly composed of chromium and iron. It is one of the main alloying agents used in the steel industry. In addition to the main components chromium and iron, it also
To calculate the ingredients, the following procedures and requirements are generally followed. (1) Raw materials and product specifications: ① Determine the production grade and c
When smelting silicon manganese alloys, silicon and manganese are reduced from the molten state of manganese silicate. MnO is easily reduced, while SiO2 is difficult to reduce. In
