Roller for Steel Rolling Mill Forged Mill Roll

Products Description

Centrifugally cast compound steel back -up rolls have a shell of cast steel with alloying elements such as Ni,Cr,Mo.After heat-treatment the roll shell get a fine temper structure, which exhibits good strength and ductility combined with high fatigue properties. When used, the roll shows a high wear and spalling resistance all the time.

Q:How to detect carbide material is raw material or recycled material, what is the difference?
The original material has uniform particle size and stable performance.
Q:What type and hardness of grinding wheel 20 for general carbide turning tools?
Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
Q:Are there any German products called K44 which are imported into cemented carbide materials?
Germany never heard of K44, I know K40 is the international organization for standardization as the equivalent of the national standard YG-10H, the hardness of about 1300HV, used for processing softwood or hardwood and nonferrous metal; K30 is equivalent to the national standard YG-8, the hardness of about 1400HV, suitable for low hardness of grey cast iron, low tensile strength steel and compressed wood.Compared with the two, K40 has higher toughness, but its wear resistance is lower.
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:K carbide carbide cutting tools, mainly used for turning what materials?
K class brand is the international standard ISO code, equivalent to China's class YG carbide brand, suitable for processing stainless steel, non-ferrous metals and alloys, as well as non-metallic materials, cast iron and other materials.
Q:Carbide and carbon steel
Carbon steel is a relatively traditional black metal material, according to the carbon content, nature, use, there are many categories. Carbon steels contain almost no alloying elements (except trace elements such as silicon, sulfur, phosphorus, etc.) during smelting. Carbon steel can be used for many daily purposes.Cemented carbide is a relatively new powder metallurgy material developed in recent years. The finish of the cemented carbide products is very high, even higher than that of ordinary quenched steel. Therefore, a machining tool that is often used as ferrous metal.
Q:What type of carbide for punching dies? Better. Where can I buy it?
Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
Q:What is the relation between the number of teeth of carbide saw blades?
1., it is mainly used for longitudinal sawing of small diameter logs. According to the size of the pre adjustment, a plurality of sheets can be sawed off at one feed, which is widely used in the sawing process of the front path, small diameter and log sawing of blockboard and finger jointing factories. 2. compared with the band saw, the processing efficiency is high, the precision is high, the operation is simple and convenient, the technical requirement of the worker is not high, and the defects of low processing precision, low efficiency and high operation technical requirements of the band saw are compensated. What is the difference between the 1:40 tooth and the 60 tooth? Because of the small friction, the 40 teeth will save effort, and the noise will be small, but the 60 teeth will be cut more smoothly. A carpenter usually uses 40 teeth. The price is the same, ha ha. For small sounds, use thicker ones, but thin quality is better. The more the number of teeth, the more smooth the cut section. If your machine is stable, the sound will be smaller. What is the difference between the 2:30 wood cut saw blade and the 40 Tooth cut wood saw blade? Main: 1 cutting speed is different. 2 different gloss. The angle of the teeth of the 3 saw blade itself is different.
Q:The difference between HSS and carbide knives
High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.
Q:Which one is better made of cemented carbide?
Overall, Zhuzhou cemented carbide works, Shanghai alloy materials factory, Zigong cemented carbide plant, new carbide knives are good. But the single pair of milling cutters is not clear! There is no YL!
