FeSi

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. Ferrosilicon is often used as deoxidizer in steel- making.

2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.

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

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

FeSi For Metallurgical Deoxidizer

Q: The difference between carbide knife and white steel knife: 1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)

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: General carbide and high-speed steel blade cutting speed? (about the range is OK.): Carbide cutting tools, cutting speed limit is 100 meters / minute, usually 50-70 meters per minute;High speed steel cutting tool cutting line speed limit is 10 meters / minute, commonly used 5-8 meters / min..

Q: Carbide yk20? What do you mean?: Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.

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: Carbide grades, properties and applicable ranges: (2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT);Because of the hardness and melting point of TiC was higher than WC, so compared with YG, the hardness, wear resistance, hardness increases, bond high temperature, strong antioxidant capacity, and will generate TiO 2 at high temperature can reduce the adhesion. But poor thermal conductivity, low flexural strength, so it is suitable for processing steel etc. the toughness of materials.

Q: How much does carbide WC contain?: For example, YG8, tungsten carbide cobalt alloy that represents an average WCo=8% and the rest of tungsten carbideTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.

Q: Carbide saw blades, plain and alternating teeth. What do you mean? That good?: .1., about the most widely used teeth, cutting speed, grinding relatively simple. Suitable for cutting and crosscut various soft and hard wood materials and MDF, plywood, particleboard etc.. Equipped with anti elastic protection around the tooth is tooth plate for dovetail, longitudinal cutting of various degree; with negative rake angle of tooth saw blade sharp, serrated cutting because of good quality, usually used for veneer cutting.2. flat tooth saw is rough, cutting speed is slow, grinding is the most simple. Mainly used for sawing ordinary wood, the cost is lower, more used for smaller diameter aluminum saw blade, in order to maintain cutting to reduce adhesion, or used for grooving saw blade, to keep the groove bottom leveling.

Q: What are the advantages of carbide V-CUT knives and diamond V-CUT knives?: The process is more complex and difficult to process. The accuracy is difficult to guarantee. The material is hard and brittle at the same time. When it collides, it breaks easily and breaks the teeth. But the abrasion resistance is good; the V-CUT knife produced is very goodThe advantages of carbide V-CUT knives are: high hardness, high strength, high wear resistance, long service life, and remarkable improvement in production efficiency.

Q: Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?: Friends, according to your question, if change my words, I choose YS25Grade ISO grouping, code name, density, bending strength, hardness, useYS25 12.8 P25 13.2 = 1780 = 90.5 for carbon steel, cast steel, high manganese steel, high strengthRough turning, milling and planing of steel and alloy steel
