Product Description:

FeSi 75 - A 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.

Apperance: lump powder ingot briquette ;silver grey or dark grey with metallic luster.

Property:high metaling point ,good heat hesistance ,high resisting and superior oxidation resisitance.

size: 10-100 mm, 3-10mm, 0-3mm 1-3mm or as customers'requirement.

Q:Carbide grades YG6 and YG8. Which ones are used to process stones?
Knock stone, choose YG8, better impact and abrasion resistance,
Q:How many temperature can the carbide valve seal reach?
The 425 degree here means that WCB carbon steel can withstand such high temperatures and has little to do with sealing. In the sealing surface location, surfacing, etc., is the role of erosion resistance. If your body can only withstand 200 degrees, but your valve that can withstand 1000 degrees, which makes sense? So resistance to temperature is a comprehensive concept, and the temperature depends on the lowest temperature resistance in all of your parts (somewhat similar to the cask theory in economics). Of course, scouring will be a little faster at high temperatures.
Q:What are the carbide cutters on Taobao?
Don't know whether you go to Suzhou haokai steel metal material limited company to see through
Q:What kind of etching solution should be used for metallographic observation of MIG and TIG welding of cobalt based carbide and medium low carbon steel? Ten
Cobalt based alloys are cobalt, which contains a considerable amount of nickel, chromium, tungsten, and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium and lanthanum, and occasionally contains an alloy of iron. According to the alloy composition is different, they can be made of wire for hardfacing powder, thermal spraying, spray welding process, can also be made of casting and forging and powder metallurgy.
Q:What about cemented carbide produced in Zhuzhou? What brand is good?
Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.
Q:What is the hardness of the carbide thread?
The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.
Q:What does WC refer to in cemented carbides?
Refers to: tungsten carbide powder, is the main raw material for the production of cemented carbide, chemical formula WC. Full name: tungsten carbide powder is black, six square crystal, has metallic luster, hardness is similar to diamond, it is good conductor of electricity and heat.
Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?
Sure, the grinding efficiency of the drill can reach about 80% of the new drill. Of course, the repair should be professional, experienced manufacturers repair oh. We can drill hard alloy coated drill bit to ensure quality.
Q:What is a hard alloy mixture?
Tungsten carbide mainly consists of tungsten carbide + other small elements,
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
