FeSi75-B 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.
Application
1. It can be used as a reductant in ferroalloy production and chemical industry.
2. In iron industry it can be used as inoculant and nodulizer.

- Q: I would like to solder a carbide tool now, what materials do you need to ask for specific methods?
- Just give you a guide to carbide cutting tools, and you'll see
- Q: What kinds of carbides are there? How should we choose in production?
- Basically divided into four major categories: YG, YW, YS, YT.YG is cast iron, nonferrous metal, base alloy steel.YW is made of stainless steel and base alloy steel.YS is the finishing of high strength steel, steel and cast steel.YT is the rough processing of steel and cast steel.
- Q: Can ceramic tools process cemented carbides?
- No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
- Q: What is the heat treatment process of cemented carbide?
- The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.
- Q: Carbide saw blade 30t and 40t what is the difference?
- A carpenter usually uses 40 teeth. The price is the same, ha ha. For small sounds, use thicker ones, but thin quality is better.
- Q: The welding welding hard alloy cutter, should use what type of flame why
- With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be
- Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!
- First of all, is the alloy itself if there are problems, product patterns, mainly to see the pattern is a kind of form, if a cluster or cluster, is generally the product of carburizing, such products also have a feature in 40 times under the anatomical microscope observation, can see the concave point, the because the graphite particles in the grinding conditions, free C from the alloy caused by the desquamation of this kind of products, should not be a problem after carburizing burnback.
- Q: What are the types of cemented carbides?
- Hello, the carbide tools are divided into the following categories:1, the whole hard alloy tools, including drill, milling cutter, reamer, boring, milling, ball milling, milling cutter, taper cutter, plug gauge, round bar and step drill.2 、 insert alloy cutting tools, including reamer, spiral end milling cutter, drill expanding cutter, automobile hub knife, three face edge, T type milling cutter and various forming knives.
- 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.
- Q: What are the carbide inserts on the turning tool welded to the handle?
- Burn copper on the knife rest.Pour the borax onto it.Put the alloy blade on it.Borax fell on the alloy blade top with flame cutting money.Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly and cools naturally.
