We export many kinds of coke, such as metallurgical coke (met coke) of 40-100 mm, theNUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on. The main source isShanxi coking plant.

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.

Also put some iron with high carbon content in high school textbooks and all the iron alloy is called ferroalloy.

Q:Detailed comparison of cemented carbide with diamond properties: Diamond is hard and brittle, with excellent performance, most of the material processing, as is the emerging industry, the production level is uneven, the high price range; processing hard alloy is less, the price is relatively cheap, because it is a traditional industry, level of production is relatively mature. If you are now worried about the choice of a tool for processing, using diamond tools or carbide tools?

Q:What are the types and types of carbide inserts?: There are too many blades, just a few examples of YG3 (used in cast iron, non-ferrous metals and alloys, precision cars or semi fine cars)YT14 (for carbon and alloy steel, semi fine and precision cars)YW1 (applicable to heat resistant steel, high Menggang, stainless steel processing, can also be used for general materials)

Q:Does the hard alloy belong to the composite material?: Grain refinement can improve both the hardness and toughness of the material. Hard alloys and cermets belong to particle reinforced composites, which change the size of hard phase and have great influence on the properties. In this paper, the preparation process of cemented carbide and cermet raw powder with different thickness is optimized, and two sets of materials with the same original chemical composition and different grain size are prepared by vacuum sintering technology.This is not how I suggest you go to Baidu search Suzhou haokai metal material limited company to ask it!

Q:What is the consciousness of YT in YT cemented carbide?: The metal material in machining, hard alloy tool material are the two common categories. Mainly tungsten cobalt tungsten cobalt (YG) and titanium (YT). There are other brands in recent.

Q:Is there any pollution in the production of cemented carbide?: The chosen of mask filter is good, also want to close modified ah buy mask anti fog and haze, one can see the standard, can be seen in the two to see that the filtration efficiency standards, should be the most familiar N90, N95 series of mask 3X brand, which is based on NIOSH standard name. In addition to the NIOSH standard, common and ASTM ASTM standard, China standard KN and the European FFP standards, can be used to measure an important indicator of masks, medical masks ordinary cheap, protective also poor, it is only suitable for ordinary nurses or at home cooking; and senior medical masks are surgery the doctor or dentist, the doctor does not care about the higher income, cost is low and the mask, pay more attention to the quality of respirator. The high grade medical mask has excellent barrier to particles and fluids, and ensures breathability and breathability in a precise working environment. Can deodorant ah, city toxic particles source: the first is the automobile exhaust the United States imported medical masks Hiroe server Hin, filter, not only anti particles but also prevent droplets. The particles as small as 0.1 micron filtration efficiency up to 99.8% of bacteria or virus vector as small as 0.3 microns (common in droplet) filtration efficiency is up to 99.9%. Using SecureFit patented technology, through adjustment to adapt to different facial shapes, to achieve high consistency, for your health and family, go out wearing masks, in the J good style East, I wish you happiness, hope to adopt

Q:What kinds of carbide cutting tools are used in the 16 and 20 manganese grinding of the lathe?: This material I have processed, it is equivalent to Q235 carbide tools, wear-resistant coarse cars, YW, fine car YT15YG: for cast ironYT: suitable for processing steel partsYW: the material performance of the tool is between YG and YTYN: it is a cermet blade suitable for machining superhard materials.Diamond: cutting tools are suitable for machining superhard materials, but they can not be processed steel or ironIn order to be compatible with them.CBN: Machining superhard materials.

Q:Customers ask whether cemented carbide can be used in the food industry! ~: The processing link is possible. Food segment will not be able to ah!

Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?: Basically the same, such as plastic wear, flank wear, crater wear, chipping... And so on, each kind of wear phenomenon has the reason, also has some remedial or the improvement measure....High speed steel has lower hardness and abrasion resistance ability is not high, but good toughness, high precision of complex cutting tools, such as broach, gear cutter or the use of high speed steel more, while the standard NC tool are used in a lot of hard alloy or indexable tool..

Q:What are the types and specifications of carbide cutters?: Classification and grade of common cemented carbide (example)Tungsten cobalt carbideThe main ingredients are tungsten carbide (WC) and binder cobalt (Co)The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average cobalt content.For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbideTungsten, titanium and cobalt carbide

Q:Several hard alloy cutter lathe with?: 2 kinds! They are clamp type and welding type.
