is a newly developed product is currently being pilot production phase

Tonghua Iron and Steel Group has successfully developed high-speed wire production HRB400ENovember 21 , Tonghua Iron and Steel Group, Shougang Tonghua Steel new line of high-speed wire rod plant produced a total HRB400E8 mm rebar 42 99.7 tons , HRB400E8 mm rebar development and production won success.
It is understood , HRB400E test seismic reinforcement steel is rolling temperature requirements are very strict , is a newly developed product is currently being pilot production phase. The production is the fourth year the plant rolling, rolling is the ball bearing manufacturer largest number of the best one , spinning temperature for the first time dropped to 900 ℃, changing the spinning temperature is not lower than the previous record of 1000 ℃ .
In the production process of organizing , the plant production department and rolling rolling workshop related personnel to develop a reasonable program , repeatedly revised operating points , follow the guidance and technical personnel on-site , requiring workers special bearings reasonably controlled roller speed, to ensure open rolling temperature , temperature and spinning into the finishing temperature , to strengthen the mill grooves , guide and guard the entrance examination , timely adjustment of the finished wire size , seismic steel products to ensure customers' dimensional accuracy requirements to ensure the quality of pruning to ensure end to end water cooling and defective parts are not all clean and trim so storage product quality to meet market and customer needs.
It is reported that the feedback from the technical center sampling data, the indicators uniformity , yield strength and tensile strength to meet quality requirements.

radial bearing a larger size, poor damping capacity

Ball bearings, roller bearings and needle roller bearings. High speed, load is small, requiring high precision rotation should use ball bearings; load is large roller bearings should be selected; loading large radial dimensions should be selected when they restricted needle bearing. Radial bearing rings of the inner and outer ring, inner ring and the shaft sleeve and often with the shaft rotates, the outer ring mounted in the bearing bore. Rolling rolling along the raceway rings, separated by the cage, to avoid friction between. Thrust bearings are divided into a tight circle and live ring in two parts. Tight circle and sleeve tight, live ring bearing in the bearing housing. Rings and rolling body with high strength, good wear resistance bearing steel, surface hardness after quenching should reach HRC60 ~ 65. Cage mostly made of mild steel stamping, and some copper alloy, bakelite cloth or plastic. Basic types listed in the table produced in China basic types of rolling bearings. Various types of rolling bearings is divided into B, C, D, E, G5 a precision. B is the highest accuracy level. G is the general accuracy level, the most common. High speed, there are strict requirements for precision rotation of the spindle, high precision bearings Special bearings should be used, such as precision lathes, milling machines, boring, grinding grinding, aircraft engine, turbocharger, precision instruments selected C, D grade; coordinate boring machine, High-speed grinding elect B, C grade. Rolling easy maintenance, reliable, good starting performance at moderate speeds higher carrying capacity. Compared with the sliding bearing, radial bearing a larger size, poor damping capacity, high speed, low life sound bigger. Rolling in the radial bearings (mainly radial force) usually consists of inner and outer rings, rolling and rolling element cage roller bearing  four parts. Inner sleeve in the journal together with the shaft rotates, the outer ring mounted in the bearing bore. In the inner and the outer periphery of the inner periphery of the outer ring are formed with raceway. When the relative rotation of the inner and outer rings, the inner and outer rings of the rolling element raceway, are separated by the cage, to avoid friction. Thrust bearings are divided into a tight circle and live ring in two parts. Tight circle and sleeve tight, live ring bearing in the bearing housing. Rings and rolling elements commonly used high strength, wear resistance, good bearing steel, surface hardness after quenching should reach HRC60 ~ 65. Cage mostly made of mild steel stamping, copper alloys can also be used bakelite cloth or plastic manufacturing

Timken Wind Energy Manager Doug Lucas

Timken through Germanischer Lloyd Wind Power Industry Technology Certification Timken bearings distributor in China Timken company learned from the United States, May 26, Timken global operations through technical monitoring authority Germanischer Lloyd Wind power industry technical certification, Germanischer Lloyd Wind power industry technical certification is a Timken Ball bearing company technology and wind power wind turbine condition monitoring system the best explanation.It is understood that representatives of Germanischer Lloyd last year visited Timken Company is headquartered in Canton, Ohio, technical center and near Fairbanks Crest steel mill. Used for the wind power industry dynamics Timken tapered roller bearings and cylindrical roller bearings rated load and bearing life test performance affirmed.
 Timken Wind Energy Manager Doug Lucas, Mr. Timken through Germanischer Lloyd in the wind power industry technical certification spoke: "Germanischer Lloyd certification is for us for the wind power industry TIMKEN bearing a technical assessment of the reliability of prove our wind power industry has a bearing more reliable than other brands, more extensive product design, we can achieve a longer Special bearings life, while reducing the wind power industry and lowering Chen. " Germanischer Lloyd Certification is Timken's proprietary Syber advanced system and bearing fatigue life testing, continues to this day for decades validation, Timken bearing various types have the ability to wind turbine bearings for the global wind power Timken industry to provide more  About Germanischer Lloyd: Germanischer Lloyd has 140 years of history, the ship testing, research and improvement of security is a world leader. In the field of wind power, wind energy Germanischer Lloyd Industrial Services department is mainly provided from materials, parts, machine to wind farm inspection, certification and other services.

Belts, bearing wear abnormal sound.

Discrimination power, transmission line fault causes abnormal sound
Car work sound vibrations of the system referred to as the sound of cars, many failures are manifested through abnormal noise, abnormal sound is phenomenal, the fault is the essence. If not timely troubleshooting can easily cause significant mechanical accident.Automotive common abnormal sound can be divided into powertrain abnormal sound, abnormal sound transmission system, driving system abnormal sound, drag abnormal noise and other categories.
1, powertrain abnormal sound
Failure occurred mainly in the engine and its related components, abnormal noise with the engine speed and change, and the frequency is higher.a. Off-cylinder engine misfire.
b. Decrease the efficiency of the engine lubrication system caused by excessive friction parts.
c. spherical roller bearing, bearing wear abnormal sound.
2, abnormal sound transmission systemDriveline abnormal noise often comes from gearbox, differential, clutch and other components with abnormal sound gear and clutch showing a significant change in status change.3, the driving system abnormal soundDepartment of abnormal noise and driving car driving status (speed, steering) are directly related.4, the drag noise
Vehicle reaches a fixed value abnormal sound obvious, speed decreases abnormal sound disappears. Mentioned here non-normal drag caused abnormal sound. Such abnormal noise caused by the flow separation around the body Special bearings changes generated noise. Specifically including cavity resonance, noise catheter tube and the antenna, wiper, mirrors and other accessories vibrations caused spoiler. Seal open, plastic parts can cause rupture of the exterior curve changes caused by traveling to the high speed air spoiler form abnormal sound.
