Is the material that ferrosilicon, ferromanganese, waste iron mixes and becomes still hard alloy good? What are the specific differences?
Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is coke, steel chips, quartz (or silica) as raw materials, smelted by electric furnace made of iron silicon alloy. Because silicon and oxygen are easy to combine into silicon dioxide, so ferric silicon is often used as a deoxidizer in steelmaking. At the same time, because SiO2 generates a lot of heat, deoxidizing at the same time, it is also beneficial to improve the temperature of molten steel. At the same time, ferrosilicon can also be used as alloying element additive, widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, commonly used as reducing agent.
Ferromanganese: An alloy of manganese and iron. Main classification: high carbon ferromanganese (containing 7% carbon), medium carbon ferromanganese (containing 1.0~1.5% carbon), low carbon ferromanganese (containing 0.5% carbon), metal manganese, ferric mirror, silicon manganese alloy.
Hard alloy has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at the temperature of 500℃ is basically unchanged, at 1000℃ still has a very high hardness. Hard alloy is widely used as cutting tool materials, such as turning tools, milling cutters, planer cutters, drill bits, boring cutters, etc., for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel, can also be used for cutting heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to machining materials. The cutting speed of new carbide tools is now hundreds of times that of carbon steel.
Different materials use different places, in general, hard alloy is better.
