Carbon & Sulfur Analyzer Tests Pig Iron
The testing of pig iron is inseparable from the Carbon&Sulfur Analyzer, the impurity elements of pig iron are mainly silicon, sulfur, manganese, phosphorus, etc. Pig iron is hard and brittle, lacks toughness, and has little ability to deform plastically, Therefore, it cannot be formed by casting, rolling, drawing, etc., but the casting and cutting performance of pig iron (gray iron) with high silicon content is good. Therefore, it cannot be formed by casting, rolling, drawing,etc., but the casting and cutting performance of pig iron(gray iron) with high silicon content is good.
Carbon and Sulfur Analyzer Test Pig Iron
Pig iron is an iron-carbon alloy with a carbon content of 2.11%-6.67% and more non-ferrous impurities. Pig iron is a blast furnace product, which can be divided into two categories: steel-making pig iron and foundry iron according to its use. Cast iron can change its internal structure through forging, modification, spheroidization and other methods to improve and improve its mechanical properties. So, Cast iron can be divided into white cast iron, gray cast iron, gray cast iron, ductile iron and special cast iron.
Pig iron can also be divided into ordinary pig iron and alloy pig iron, and the ordinary pig iron is including steel-making pig iron and foundry pig iron, the latter is mainly ferromanganese and ferrosilicon, alloy pig iron us used as an auxiliary material for steel making, such as deoxideizer and alloy element additive. Ordinary pig iron accounts for more than 80% of the current ordinary pig iron. With the progress of industrialization, this proportion has gradually increased.
From a broad perspective, iron is also divided into chemical purge iron(containing C is almost zero), industrial pure iron(containing C＜0.05%), and sponge iron, granular iron and so on. But they are not blast furnace iron smelting products, and their uses are also different. Using pig iron carbon and sulfur analysis instruments can accurately test the content of carbon and sulfur.
When the C content in iron is in the range of 0.03%-1.2%, it is steel, and the iron containing C 1.2%-2.5% lacks practicality, and industrial production is generally not carried.
