Nanjing high precision drive equipment manufacturing group Co., Ltd.

Customer introduction: Specializing in the production of high speed heavy load gear (wind power industry) industry leading enterprises, the total capacity of wind power main gear box is ranked first in the world, the scale of output value and equipment capacity in Asia is the first in Asia, the world is second. state of use:It has more than 200 different types of industrial heat treatment production lines, and produces about 8000 large scale wind turbine gear trains.

Challenge: the early use of German brand quenching medium, the rapid expansion of enterprise scale, while the quality of product stability, systematic service and effective control of the higher requirements. The diameter and thickness of the 42CrMo workpiece can not meet the market demand, and the impact energy is unstable.

Solution:Through preliminary investigation, investigation and analysis and testing, the final selection of KR-228 (fast light quenching oil), after debugging, the maximum diameter of the workpiece ring can reach 3M, the tooth thickness before 30~33mm, after the treatment of the quench medium, can reach the 100~200mm range, greatly improve the quality of the work. Under zero 40 centigrade, the enterprise set the impact work standard of > 35 coke, the original medium impact work data in the 30~35 interval, lower than the standard, the statistics of the company's product data, in the 37~40 range, in line with the enterprise expectations.
