Introduction of High-End Large Roller Production Line
Huigong bearing roller production line can produce all kinds of high-precision cylindrical and tapered rollers in the range of 15mm to 160mm in diameter and 20mm to 220mm in length, with an annual output of over 3 million pieces and product precision up to G1 and G1A (Grade l) standards. More than 150 sets of various precision equipment, and various perfect special testing instruments, ultrasonic flaw detection (UT), magnetic particle flaw detection (MT), eddy current flaw detection (ET) instruments, spectrometer, carbon and sulfur analyzer, roundness meter, contour roughness meter, etc. The heat treatment line can independently guarantee product quality, fully realize quality control adopted in the whole process from raw materials to finished products, the production process of turning, heating, and grinding in an orderly manner, and the flaw detection, sorting, oiling, and packaging completed in one stop.
Heat Treatment Line
CHG has brought in heat treatment line of world-class Aichelin technology, pusher furnace carburizing quenching, and roller hearth furnace secondary quenching, and can visually display its entire production, monitor, and record automatically its processing parameters and quality data. Pre-oxidation before carburizing can make the carburized layer of products more even. The main quality indexes need to meet: to be 1～8mm in the depth of carburizing layer in need; ±0.O5％ of the carbon potential deviation in the carburizing furnace, ±0.1 mm of the same roller carbon penetration deviation; carburizing furnace, thermal insulating furnace, high＆low temperature tempering furnace, ±1°C temperature control accuracy of roller rod heating furnace, ≤±5°C uniformity of furnace temperature. Nitrogen protection is adopted in high-temperature tempering, while atmosphere protection is adopted in roller hearth furnaces, which makes sure that the carburized steel roller can avoid decarburization, the decarburizing layer depth in the heat treatment for high-carbon chromium-bearing steel rollers is≤0.03mm; Residual austenite content of the finished rollers is less than 8％.
Testing Instrument
The three-Coordinate Measuring Machine(CMM), Spectrometer, OPTIKA Metallographic Microscope, Carbon and Sulfur Analyzer, Digital Vickers Hardness Tester, Roundness Meter, Contour Roughness Meter, and other testing instruments, ensure that the testing indexes of the products meet the requirements of the Quality Control System.
Sorting and Packaging
With automatic sorting and testing, inspection, and packaging line, it can realize one-stop completion from Eddy Current Flaw Detection, Ultrasonic Flaw Detection, cleaning, sorting, typing, and oiling to packaging. The accuracy of diameter sorting measurement reaches 0.5μm, the accuracy of length measurement reaches 1μm, and the accuracy of cleanliness reaches ≤2.5mg/kg, to ensure zero defects and more reliable quality.
