Heat treatment technology application effect
For large load to withstand the railway, rolling mill bearings, quenched by M after the main failure mode is used: When the inner sheath cracking, the outer wall of the outer wall of the block during use, the inner ring fragmentation, and austempered bearings Due to good impact toughness and surface compressive stress, no matter whether the inner sleeve is cracked during assembling or the outer sleeve is blocked off during use, the propensity of the inner sleeve is greatly reduced and the stress concentration on the edge of the roller can be reduced. Therefore, after quenching after quenching than M, the average life expectancy and reliability increase.
The development potential of powder metallurgy is huge
In the current market situation, powder metallurgy products in the market is very active, but also has great potential for development, the future development space is infinite. In fact, powder metallurgy products in the market has a very large development potential, because it can accurately grasp the needs of users to meet the various aspects of the user, so it can occupy a very important position in the market.
Application of plastic flame spraying
6, insulation coating large rectifier, welding machine, start the motor wire is relatively thick, insulation damage, you can also use spray coating to repair. For some parts require insulation of the workpiece, plastic spraying is more suitable. In addition, plastic spraying in the high-frequency, high pressure situations, can also be applied. 7, shock absorption, sound-absorbing materials Vibrating feed mechanism work noise, poor working environment, the operator is also very easy to fatigue. For this purpose, the coating can be sprayed onto the area where the feed mechanism contacts the workpiece, which significantly reduces the noise and improves the working conditions. 8, decorative, anti-rust layer All kinds of machine tools, ships, vehicles handle, handle and other manipulation parts, usually with the plating method to solve the decoration, rust problem. 9, insulation materials Some pneumatic tools, operators in contact with compressed air circulation pipes will feel very cold, especially in winter, the operator will even be frostbite. If the parts in contact with the hand spray nylon or plastic coating, you can greatly reduce the hazards of freezing on the operator. 10, paper industry shaft and sleeve size, size guide wheel. Can be applied plastic spraying process. 11, oil, acid, minus, salt...
Lang Feng materials held year-end wrap-up meeting
The meeting summed up the work of the year 2016, the financial situation summary, proposed in 2017 the company’s strategic plan, graphene new materials, strategic planning, to achieve the dream of achieving a better dream. The conference was a complete success.
Application of Heat Treatment Technology
In the production of railway and rolling mill bearings, because of the large size and heavy weight of the rolling mill, the M-structure is brittle in the quenching of the steel. In order to obtain the high hardness after quenching, the strong cooling measures are often adopted, resulting in quenching microcracks. BL structure is much better than M organization toughness, while the surface of the formation of up to -400 ~ -500MPa compressive stress, greatly reducing the tendency of quenching crack; grinding in the surface stress to offset part of the grinding stress, the overall stress level Down, greatly reducing the grinding cracks.
Definition of Powder Metallurgy Manufacturing Industry
Powder metallurgy is a branch of metallurgy and materials science, is to manufacture metal powder and metal carbide powder (including mixed with a small amount of non-metallic powder) as raw materials, forming – sintering method of manufacturing materials and products industry. According to the “Classification and Code of National Economy Industry” formulated by the National Bureau of Statistics, China has classified the powder metallurgy manufacturing as a metal processing machine (C342) in the manufacture of general equipment (CFT 34) and belongs to forging machinery manufacturing (C3423).
