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: What are the standard units of measurement for carbide inserts?
- It used to be priced by KG, and now it's on a tablet basis
- Q: What material is that ultrafine cemented carbide?
- You mean the ultra-fine grain cemented carbide, generally we have 0.6 alloy grain size is fine, which belongs to the tungsten carbide base hard alloy, ordinary tungsten carbide base hard alloy strength and hardness are higher than the same cobalt content. The process is mainly mixing, wetting, drying, forming, sintering, finishing, such as sand blasting, CVD/PVD coating, heat treatment, etc.
- Q: What are the main items of cemented carbide production process and finished products inspection, as well as the price of testing equipment, equipment and equipment?!! Please experts advice and answer, the younger brother will be grateful!!!!!!
- The school's equipment, the majority of the real carbide testing equipment used to study and learn from students, is not equipped with what you see,If you want the most common words, use the following set of scenarios1, magnetic, magnetic saturation instrument, there are also Hunan Normal University2 domestic Hengping density meter3 Ji'nan test the strength of machine4 Rockwell hardness can be used in Shanghai material factory5 Shanghai 5 optical microscope can also plant or lightMetallographic sample preparation equipment can be used in Shandong, Laizhou6 carbon oxygen equipment can be used by Beijing ng7 Scott velocity loose can only buy Beigang HospitalIf you want a mid-range or advanced point, you can add me to chat, and rest assured that I am not selling equipment, and in this line I have been doing it for 10 years
- Q: Carbide according to the structure of the words, what can be divided into?
- Hard alloy is by grade, can be made into all kinds of special-shaped parts
- Q: What are the features of cemented carbide YG8 knives?
- Density: 14.6-14.8; hardness HRA:90.5; flexural strength, Mpa2300High bending strength, shock resistance and vibration resistance is better than YG6. It is suitable for low speed rough machining of cast iron, non-ferrous metals and their alloys, and non-metallic materials
- Q: What is hard alloy grinding?
- Its scope of application and the artificial diamond plays a complementary role. Cubic boron nitride wheel grinding of steel parts the efficiency ratio of corundum wheel to nearly a hundred times, five times higher than the diamond grinding wheel, but less than the diamond grinding of brittle materials.The diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard processing material
- Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
- The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.
- Q: Is the hard alloy the same as the cemented carbide?
- Superhard alloy and cemented carbide are not the same ah.Personally, the alloy feels like a metal of high hardness; for this is not very familiar, there is no right to speak;But the main component of cemented carbide is WC+Co. And some have TIC.TaC. Equal carbide. Basically out of the metal range.So you say cemented carbide and hard metal are different.If it is replaced by superhard materials and cemented carbide to compare. The carbide can be cemented into the superhard material.These are personal views and can be discussed more
- Q: The difference between cemented carbide and tungsten.
- Tungsten 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.Also known as tungsten steel, hard alloy, refers to the sintering of the composite materials containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide is tungsten steel common components. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grains are bonded together with metal binders. Binder usually refers to metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The composition of an undetermined carbide and bond phase is called "grade"".
- Q: How hard is the carbide knife?
- The sintering temperature of the cemented carbide is about 1200 degrees centigrade. The welding temperature of the tool copper is about 850 degrees, the brazing of silver is about 700 degrees centigrade, the temperature of the metal cutting point is about 800 degrees, and the cutting temperature of the woodworking will not exceed 100 degrees centigrade.
