products information

Our factory supply 75% 72% 65% 45% four grades of ferrosilicon.

Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.

Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.

High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing.

In the steel industry, one ton of steel consumes about 3 ~ 5kg75% ferrosilicon.

Q:How are cemented carbides sintered?
After cooling, the hardened phases are distributed in a grid of bonded metals that are closely related to each other and form a solid whole. The hardness of cemented carbide depends on the content of the hardened phase and grain size. The higher the content of the hardened phase and the finer the grain, the greater the hardness. The toughness of cemented carbide is determined by bonding metal. The higher the bonding metal content is, the greater the bending strength is.
Q:Method for assembling hard alloy cold heading die
Technological requirements for hole processing of cemented carbide die:1, carbide mold hole processing, selection, processing methods: according to the requirements of the drawings, select the electrical processing methods.2, select electrode material: according to the processing requirements, determine the processing methods and processing equipment to determine the electrode material.3. Design electrode: Design electrode according to clearance, shape and effective length of blade.4, processing electrode: generally use shaping grinding or square planer processing.5 、 clamping electrode.6, be processed carbide mold preparation.7. Calibration electrode.8 、 carbide mould clamping and positioning.9. Adjust the upper and lower positions of the spindle head.10, processing preparation.11, boot processing.12, regulation switching and intermediate inspection.13, carbide mold inspection: carbide mold after processing, should be carefully checked according to drawings, whether it meets the requirements of the drawings
Q:Which carbide alloy factory in Hunan is good 10
Zhuzhou China Tungsten Alloy Co., the company's main products are: sand making machine alloy strip, mining carbide tools, hard alloy, hard alloy, hard alloy mould plate, carbide blade, cutter, hard alloy, etc. at the same time or special "diamond" brand hard alloy cutter dealer. The company uses one to one service, reasonable price, cost-effective, prompt delivery, heavy credit, Shou contract, guarantee product quality and other thoughtful service, so that you can rest assured.
Q:Hard alloy die polishing with what can be reached Ukraine black brightness
Recycling all kinds of scrap carbide, waste alloy powder, alloy polished powder
Q:What type of emery grinding machine is 3000/min for grinding carbide turning tools (e.g., YG8.YS8.YT15.YW1, etc.)?
Diamond grinding wheel, green carborundum wheel can be used. Two, choose one, or choose the former good. Diamond grinding wheel has the advantages of less wear, long life, high productivity and good processing quality, that is, the price is a little more expensive.
Q:Buy whole cold carbide drills
I know Zhuzhou Hua tungsten seems to have what you need. I suggest you go to see their company
Q:What are the cemented carbides?
Tungsten cobalt carbideWC cutterThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.
Q:Carbide drills and high-speed steel drills, which are suitable for processing stainless steel 10?
High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.Serious work hardeningAustenitic stainless steel and some high alloy stainless steel is austenite, high work hardening tendency when cutting, usually plain carbon steel several times, the tool in hardening region cutting, shortening tool life.Easy to stick the knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts.   Tool wear acceleratedThe materials generally contain high melting point elements, large plasticity, high cutting temperature, so that the tool wear faster, sharpening and changing knives frequently, thus affecting the production efficiency and improving the tool cost.Mainly to reduce the cutting line speed, feed. With special processing stainless steel or high temperature alloy cutting tools, drilling, tapping the best internal cooling
Q:What is a hard alloy mixture?
The cemented carbide mixture refers to a WC+Co mixture to be suppressed, and contains a small amount of additives (possibly paraffin, rubber, etc.) that can improve the compressive properties. There is also a saying called RTP (Ready To Press).
Q:Compare the advantages and disadvantages of high speed steel and cemented carbide
Must be in a hardened state, in high speed steel iron, chromium, tungsten and carbon forming hard carbide can improve the wear resistance of steel (hardness of HRC6468). Another part of tungsten dissolved in the matrix, increase the hardness of steel red.High speed steel can reach 650 degrees of red hardnessHigh speed steel has good strength and toughness, cutting edge is sharp after grinding, and its quality is stable. It is used to make small and complex cutting tools
