Product Description:

Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

Q:What is the resistivity of the yg13 cemented carbide?
Three, technical parameters of YG13 tungsten steel1, WC and other alloy composition content%:87.2 and CO content%:13.3 density g/cm3:14.2.4 hardness HRA:90.5.5 、 grain size um:0.6 ultra-fine grain alloy.6. Flexural strength MPa:4000.7 thermal expansion coefficient 10-6/0C:5.8.8. Modulus of elasticity GPa:460.
Q:What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.
Q:Machining center 8 mm carbide cutter processing 45 steel, how to set the speed, feed, and moving speed?
You should be a 8 mm tungsten steel milling cutter, the speed should be controlled below 2200 to 3000, because the speed and your cutting are related to the amount of advice:
Q:Hard alloy die polishing with what can be reached Ukraine black brightness
What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder
Q:What is the hardness of cemented carbide?
Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
Q:Can ceramic tools process cemented carbides?
No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
Q:Compare the advantages and disadvantages of high speed steel and cemented carbide
High speed steel, high carbon steel, can be divided according to chemical composition of tungsten and molybdenum in steel, cutting performance is divided into high performance of ordinary high speed steel, high speed steel. Through strengthening heat treatment of high speed steel.
Q:Is Zhuzhou the largest cemented carbide producer in Asia?
Of course, yes, or how could the 601 factory be so famous? That's the old military enterprise. It's the hard tool factory now. I hope it can help you!
Q:How are cemented carbides separated from the cutting tools?
Brazing heating to melt after the pain, you can take off!
Q:What cemented carbide does 2gr13 use?
2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.
