Product Description:

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 hard is the carbide knife?
Cemented carbide has high hardness, high temperature resistance and good red hardness. It can still maintain good cutting performance at high temperature about 1000 degrees centigrade.
Q:Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?
It has 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:5 meters long hard alloy bars, where are they sold?
Almost impossible to sell, you can choose to use media, multi section welding, bonding completed.AskMultistage welding? What welding is it?Chasing the answerUsing a steel as the matrix, the copper inserts are used to complete the desired specifications.
Q:Carbide cutters can work on materials of higher hardness
This problem is too general, and hard alloy processing range is very wide (it also has many kinds of material), from soft aluminum alloy, copper alloy to HRC60-70 degree of mold can process, the key is to see what you want to process materials
Q:What kind of cemented carbide is the most wearable?
The impact resistance and hardness of the YT5 are of course, but not wear resistant. Wear resistant should belong to the YT15, recommended to do rough, with T5 finishing requirements of high use T15, because T15 impact resistance is too bad.
Q:What does "YC20.1 carbide" brand mean?
PaInstead of old products, YT15 YT14A new brand with a slightly higher price of 40%, which has not been done
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:What kind of industry can use carbide?
The metal processing tool, electronic industry to do the drill bits, the medical industry mainly do the drill. Carbide tools have been used in various industries, known as industrial teeth.
Q:YC45 carbide cutting tools 10
YC45 hard alloy cutter is made of tungsten alloy tool. The main alloy components are tungsten and cobalt, which have better wear resistance, good weldability, and good effect in processing solid wood, redwood and so on. Is a widely used, stable quality alloy, can also be used for cutting tools of various metals. Tungsten alloy containing tungsten 18%, hardness of Vivtorinox 10K, second only to diamond. The product has the characteristics of tungsten steel is not easy to wear. Commonly used in lathe tool, drill bit, glass knife head, tile cutter, hard but brittle annealing.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal. 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. 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. High hardness (86-93HRA, equivalent to 69-81HRC); good thermal hardness (up to 900-1000 DEG C, 60HRC); good wear resistance.Carbide cutting tools than high speed steel cutting speed 4-7 times, 5-80 times higher tool life. Manufacturing dies and measuring tools, life expectancy is 20-150 times higher than alloy tool steel. Hard material that can be cut around 50HRC. But the hard alloy brittleness, cutting can not difficult to make the whole cutter with complicated shape, usually made of different shapes of blade, mounted on the body or use a knife die body by welding, bonding and mechanical clamping method.
Q:Can YG813 carbide cutters be used for cutting stainless steel intermittently? How much is the cutting speed?
YG type alloy has good impact resistance, can be used to cut stainless steel, cutting speed 80m/min, heightening the concentration of emulsion about 8%, of course, if there is YW alloy better, wear-resistant, heat hardness and hardness are higher
