Product Description:

FeSi75-B for Casting Manufactural and Steel Making

 

Description

 

Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.

 

Application

 

1. It can be used as a reductant in ferroalloy production and chemical industry.

2. In iron industry it can be used as inoculant and nodulizer.

Q:Tungsten steel could be used to do is hard alloy knife?
Of course you can need what specifications of tungsten steel knife
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.
Q:The welding welding hard alloy cutter, should use what type of flame why
With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be
Q:What materials are ZK20 cemented carbides processed?
ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic
Q:What is the difference between hard alloy and steel
Cobalt (Co) is used in bonding in the alloy, is in the process of sintering, it can make the tungsten carbide (WC) powder and tightly surrounded Bonded together, after cooling, became hard alloy. (equivalent to the cement content). Usually: 3%--30% tungsten carbide (WC) is the main component of some metal properties of the hard alloy or cermet, the total composition of 70%---97% (weight ratio) is widely used in wear-resistant, high temperature resistance, resistance corrosion, bad working environment of the parts or tool, cutter tools.
Q:What are the advantages of carbide V-CUT knives and diamond V-CUT knives?
Precision machining, high finish, sharp blade, machining V groove surface smoothness, no burr burr, greatly improve product quality.Polycrystalline diamond V-CUT knife is now used more and more, and its advantages are: hardness is higher than hard alloy, longer service life, especially in the CNC V-CUT Slitter, the use of good results.
Q:What kind of cemented carbide is the most wearable?
Tungsten particles smaller, higher hardness, higher wear resistance.Mainly depends on the use of conditions, the most wear-resistant carbide materials may be more brittle, so it may not be able to use.According to the hardness and toughness of cemented carbide is divided into several types, such as YG8, YG15 etc., is the wrong type of high speed steel has great influence on the service life, may your home (peak steel) inside with a tungsten component but not tungsten.Cemented carbide is a powder metallurgy process with tungsten carbide as the main body and sintered with cobalt or other bonded metals. The tungsten content of tungsten carbide is above 80%.Tungsten is a hard alloy. Tungsten is raw material for smelting ferrotungsten adding steelmaking process in molten steel for tungsten and also called high speed steel or tool steel, the tungsten content in 15-25%.
Q:Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy
Ha ha, I'm good at that!HC is the sign of the attractive magnetic force of the alloy, and HRA is the sign of hardness. COM is the cobalt magnetic mark of the alloy. D is the density of the alloy. The general quality certificate of the alloy product will have three indexes above
Q:I would like to ask cemented carbide grade YK15,
Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced
Q:Hard alloy and cast iron join together, what glue is good?
Carbide and cast iron are preferred welding methods. Instead of bonding.Can use oxygen acetylene flame gas welding (high combustion temperature, acetylene to hard alloy is heated to a suitable temperature, can be used instead of propane gas), first to the hard alloy is heated to (dark observation) small red, give heating. Were mixed with borax and boric acid as flux, HS201 copper wire dip brazing flux hard alloy and cast iron welding.Bonding shall be considered without welding conditions.The cast iron and carbide surface is polished with fine sandpaper. A soft cloth for wiping dirt and grinding residue. 1:1 AB glue evenly, smear on the contact surface of cast iron and hard alloy. Slightly pressurized. Set aside for 12 hours.
