1 Application

Ferromanganese a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese. Ferromanganese is used as a deoxidizer for steel.

Application

1. Mainly used as alloy additives and deoxidizer in steelmaking.

2. Used as alloy agent ,widely applied to be widely applied to alloy steel, such as structural steel, tool steel, stainless and
heat-resistant steel and abrasion-resistant steel.

3. It also has the performance that it can desulfurize and decrease the harmfulness of sulfur. So when we make steel and cast iron, we always need certain account of manganese.

Q:What are the three types of commonly used cemented carbides?
Common brands are YT5 (mass fraction of TiC is 5%), YT15 (mass fraction of TiC is 15%), with the mass fraction of TiC increased, the mass fraction of cobalt decreased, hardness and wear resistance increased, bending strength decreased. This kind of hard alloy is not suitable for processing stainless steel and titanium alloy.K class (equivalent to China's YG class), cemented carbide composed of WC and Co, also known as tungsten cobalt carbide. These alloys are mainly used to process cast iron, nonferrous metals and their alloys. The common grades are TG6 (cobalt mass fraction 6%) and YG8 (cobalt mass fraction 8%).
Q:What are the types and specifications of carbide cutters?
The main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.For example, YT15 is a tungsten titanium cobalt carbide that represents an average WTi = 15% and the remainder is tungsten carbide and cobalt content
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:What are the advantages of carbide V-CUT knives and diamond V-CUT knives?
Precision machining, high finish, sharp blade, machining V groove surface smoothness, no burr burr, greatly improve product quality.Polycrystalline diamond V-CUT knife is now used more and more, and its advantages are: hardness is higher than hard alloy, longer service life, especially in the CNC V-CUT Slitter, the use of good results.
Q:Is there a material that is more wear-resistant than cemented carbide and has a relatively low cost?
If it is numerical control tool, it is more wearable than cemented carbide: ceramic, CBN, diamondAmong them, the lowest price of ceramics, diamond prices are highest
Q:What are the differences between the two grades of carbide, YT15 and YT5?
YT5 is often used for roughing or machining, impact cutting, and YT15 is usually semi finishing and finishing.
Q:Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?
The two materials are not good or bad, the key is to look at the application!!Carbide drill, high hardness, wear resistance, high efficiency, toughness slightly worse, therefore, the rigidity of the machine tool and spindle runout and speed are required!Cobalt high speed steel including ordinary high-speed steel, good toughness, edge processing can be very sharp, more suitable for processing some sticky materials, of course, low strength materials will be nothing difficult, but its high temperature resistance, wear resistance is relatively poor, the drilling speed is not high!!Therefore, the choice of drill or according to your working conditions to choose,
Q:Machining center 8 mm carbide cutter processing 45 steel, how to set the speed, feed, and moving speed?
Faster, two RPM 1 mm, too fast, with G96 RPM feed 0.2 below
Q:What is hard alloy grinding?
Diamond grinding wheel in grinding hard alloy and non-metallic materials, has a unique effect, but in the grinding of steel material, especially grinding special steel, the effect is not significant. It is composed of cubic boron nitride (CBN) grinding cubic boron nitride particles sticking to the ordinary wheel surface only a very thin layer, the abrasive wear the hardness, toughness and durability of corundum wheel is 100 times, the most suitable for processing high hardness, high viscosity, high strength, low thermal conductivity of grinding hard steel and high or super high speed grinding.
Q:What are the main uses of carbide round rods?
I have some hard alloy round bars (tungsten steel) and high speed steel round rods (all used for cutting tools). Now I want wire cutting, laser, diamond, wire cutting
