Rolled form of the strip to the roll direction, powder rolling can be divided into vertical rolling and horizontal rolling and tilting rolling three forms: vertical rolling of more general use, and there is a certain representation. Its size mainly depends on the state of powder properties and the roll surface. It includes the apparent density of powder loose powder flowability, powder compressibility and powder forming, etc. In early 1960s, China began to study Flocking Equipment the powder forming technology and achieved remarkable results. Tube history of metal powder rolling is from the middle of the 19th century.1mm.; rolling process parameters. As filtration and separation components, silencers, resistance, flame, electrical and magnetic materials as well as wear and friction materials, these materials are widely used in chemical, electronics, petroleum, machinery, automotive, instrumentation, nuclear and aerospace industrial sector.
After the powder in contact with the roller surface, only when the roll rotation (from the centerline of two roll) come to an angle, the powder can be roll bite and go into the deformation zone. Such as roll diameter, roll gap and rolling speed, roll surface state for the material way.) powder or alloy powder rolled into the porous or dense sheet, strip, foil, wire and tube, and the combination of materials as well as metal or metal and nonmetal.
It is more suitable for the preparation of dense material. But in the 1940s to 1950s, it had rapid development and achieved fruitful results in powder rolling theory, technology, equipment and materials applications. Two-roll mill roll diameter is 900mm, maximum thickness of the rolled strip is 10'mm; minimum of four-high rolling mill work roll diameter lOmm, rolling out the thickness of the porous thin strip of about 0. According to the principle of rolling around the powder weight equivalent, can be drawn from the relationship between the porous strip density and thickness of the powder bulk density and other factors. The former processes, including rolling and raw strip sintering, but in the preparation of dense material, they also need to add the necessary finishing and annealing.
According to the powder metallurgy history and national conditions, the number of Chinese metal powder exporter in production of high strength, high-density parts is small. As the qualified boron dwindling and chemical composition mixed, it is bound to promote the ore powder and restored boron powder. Technology development with the powder forging, powder forging Flock Machine using the powder has matured. And Due to the technical and development capabilities of powder metallurgy products, most of China's production is in low-density parts.mhcmp. Boron powder production atomization of boron powder with water-based, improve its R & D work more, not much improved restore the performance of the boron powder. Therefore, the reduction of boron powder in China occupy the boron powder market, the opposite is true with other countries. Of particular note is the powder lubricant, temperature and pressure, the die wall lubrication, evil strength of the lubricant. In order to improve the uniformity of the density of green products to improve the repression process, pre-mixed powder is now maturing to adapt to the temperature and pressure process to improve the green density, temperature and pressure flour into a big step. Dense particles of water atomized powder of boron powder, high purity, good compression, and easy to alloying, the manufacture of high school strength and density of powder metallurgy parts in China, efforts to promote, in particular, is pre-mixed powder.
As the economic and technological development, the fluctuations in the development of automobile industry, the overall trend of boron powder is stable and rose slightly, from 8% to 10% of the passive margin, the peak can reach 850 000 t 780 000 t trough, however, car increase in the amount of powder metallurgy parts for motorcycles. It adapt to moderate-intensity parts.com
The rest boron powder is used in the chemical industry, magnetic materials, cutting, welding rod and heating materials. Due to the limitations of manufacturing process, with the guarantee of high compression, how to improve the bulk density is an important problem.Research and development direction of Chinese boron powder is to improve the purity, retain high compression and solve the structural problems of aggregation of inclusions. Promotion of water-atomized iron powder is a general trend, but now accounts for 80% of the market to restore the boron powder, which is the international problems encountered with Chinese characteristics. Vehicle production fluctuations, but the total production of boron powder is not less than 850 000 t, before the new process, the capacity surplus. The next few years to restore the boron powder is an important part of industry development and research of boron powder.
From the powder metallurgy product performance requirements of the development of new products came into being, for example, to improve the density and strength of powder metallurgy parts, adding a nickel, copper, chromium, molybdenum and other elements, so the diffusion alloy powder, researchers continue to deepen. Green strength over 40 MPa can be machined. Because the concentrate powders compositions are stabile, it improves the stability of boron powder
FBE coating is an industry standard, environmentally-safe thermoset polymer coating which is used as corrosion protection for pipe.
During the FBE process:
According to the statistics of the international nickel market in recent years, the consumption volume of a variety of nickel carbonyl products which produced by carbonyl is about 13 to 15 million tons, accounting for almost 17% of the average amount of nickel consumption in the world. In recent years, with the energy, communications technology and the continuous development of the family car, nickel carbonyl products showed a rapid upward trend, annual growth rate is about 10%.com
In recent years, despite the large fluctuations of the nickel price, but nickel carbonyl powder prices have been stable at 12,000 to $ 13,000 per ton. The main products are nickel carbonyl powder, powder coated and nickel carbonyl --- alloy powders, mainly for military use, China's nickel carbonyl products are now mainly rely on imports.mhcmp. According to Chinese electronics, energy and powder metallurgy market research, nickel carbonyl powder consumption growth is very rapid, only in 1999, Chinese nickel-metal hydride battery industry was imported nickel carbonyl powder up to 2200 tons, and still fast grow with 20% Flock Machine annual growth rate, in 2004, Chinese nickel carbonyl powder consumption was up to 3000 ~ 3500 tons, nickel foam consumption was around 800 tons. Moreover, as technology advances, especially today's rapid development of nanotechnology, it is foreseeable that the demand of nickel carbonyl and products will increase significantly. And with the new technology, new materials continuous developing, especially meet high-performance capabilities and structural materials needs, such as nickel inner electrode MLCC, PTC thermistor, production and application of high-performance carbide, etc. Due to special structural state nickel products prepared by carbonyl with excellent physical and chemical properties, is an important raw material in many fields, especially in high-tech industry, so the market prospect is very broad., in 2005, the requires of sub-micron (nanometer) ultrafine nickel powder was reached hundreds of tons. Pyrolysis nickel carbonyl, can be prepared a variety of products with different properties, different shapes, such as zero-dimensional materials (nm, micron powder material), one-dimensional material (needle and filamentary materials), two-dimensional material (film material) and three-dimensional materials (nickel-pill, coating, gradient and hollow materials) and so on.Chinese nickel carbonyl powder currently is only produced by Nuclear Corporation. In addition, the worlds nickel carbonyl products market has been monopolized by the International Nickel Company, the international market price of nickel carbonyl also become a monopoly price.
Design capacity is 500 tons of nickel carbonyl powder. However, due to various reasons, it has not been possible up to production. In addition, the nickel-pill which mainly used in steel and chemical raw materials production, because the demand of stainless steel expanded and the material properties requirements increased, the annual consumption can up to 5,000 tons. Carbonyl is a process of refining nickel, simple, low energy consumption, high extraction rate, also conducive to the enrichment of precious metals, is a no waste environmental technology.
