1. Structure of Magnesium granule Description：
Deoxidizer. Removing the oxygen in molten steel in the process of steelmaking, some ferroalloy can removing the other impurities such as sulfur, nitrogen in steel.
Additive in alloy. According to the requirements of steel composition, adding alloying elements in the steel to improve the performance of the steel.
Inoculant. In front of the cast iron casting in molten iron, improve the crystallization of castings.
Reducing agent to the metal thermal reduction process in the production of other alloy and nonferrous metal reducing agent; Non-ferrous alloy alloy additive; Also a small amount of used in the chemical industry and other industries.
All steel, steel capital is a kind of ferroalloys, it also makes the iron alloy is the most widely used, dosage biggest alloy.

5. FAQ
Also put some iron with high carbon content in high school textbooks and all the iron alloy is called ferroalloy.
- Q: suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?
- 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: Can hard alloy be welded with silver electrode?
- Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.
- 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: Chengdu which has carbide scrap acquisition point?
- Bars of 75000 yuan / kg (Fu Xujian) Zhejiang Zhoushan self-employed waste tungsten 150-200 yuan / kg, Hebei Hengshui Gucheng County Sindh rare metals tungsten tailings 100-300 yuan / ton Guangzhou lechran gold bars 1200 yuan / kg, Zhengzhou Zhengzhou Hongsen tin small PCB tungsten steel drill 160-190 yuan / kg in Zhejiang Taizhou
- 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: What does carbide wet grinding mean?
- Wet grinding of cemented carbide is an important process in the production process, and its efficiency has a direct bearing on the quality of cemented carbide products. The main factors affecting the wet grinding efficiency of cemented carbide are as follows:1. ball mill speedThe mixing and grinding of cemented carbide powder in a ball mill barrel is achieved by the motion of the ball when the ball mill rotates. The movement of the ball in the tube depends on the speed of the ball mill. If the speed is too fast, from the heart, the ball will be posted on the wall and rotate together, the ball in the same cylinder wall relative static state, which is equal to the elimination of the ball should play a role, if the speed is too low, only along the bottom of the cylinder sliding ball, small mixture of crushing and grinding effect.
- Q: Carbide grades, properties and applicable ranges
- (4) tungsten titanium tantalum cobalt (WC+TiC+TaC+Co) cemented carbide (YW);In addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, anti oxygen ability and wear resistance. Both can be processed and can be made of steel, cast iron and nonferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy) mainly. For the processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing.
- Q: How to solve the severe wear of the flank of the carbide blade during machining?
- 2. Contact the company or log on to the company's website for communication.Carbide inserts are made of hard alloy, an alloy made from refractory metals, hard compounds, and bonded metals by powder metallurgy.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
- Q: After welding, and then sharpening, grinding into 4 Pyramid shape, and then used to knock stone, which is not easy to bad, which is more durable? Model number is D224, I would like to ask you, which should I buy? I'm mainly used for knocking stones.
- YG8C is used on impact drills, which is suitable?
- Q: What are the common kinds of cemented carbides?
- The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as YW1. (2) grade, composition, performance and application of commonly used hard alloy (see table below) categories of chemical composition of W/% grade performance scope of tungsten cobalt alloy YG3X 96.5 - < 0.53 for cast iron, nonferrous metals and alloy fine boring, fine car, can also be used for fine machining of alloy steel, Quenched steel and tungsten and molybdenum materials; high tungsten carbide content, binder content is low, its high hardness, flexural strength is low; therefore, YG3 is suitable for finishing; whereas the YG15 can bear larger load, suitable for roughing. Suitable for cast iron, nonferrous metals and alloys and non metallic materials roughing during continuous cutting, interrupted cutting of the semi refined car, fine car for percussive rotary drilling machine drilling hard rock, containing coal cutter teeth, hard rock drill, well drilling hard rock percussion drill bit, stamping die, planer and knife for percussive rotary drilling machine and other chisel hard and extremely hard rock, in the epidermis processing great work under stress perforation and stamping tools tungsten titanium cobalt alloy YT5 855 - 10 for carbon steel, alloy steel, forging, stamping, casting, uneven section, rough turning, discontinuous cutting the rough plane semi finishing.
