Heat treatment equipment in the application of wind power transmission gear heat treatment
At present, the use of wind power gear box are GE, vader, Dr Rexroth, dimensions, and other foreign companies, as well as the meteorological tooth, tooth tooth, big big heavy, hangzhou, double the company's gear box, etc.
Gear box of the external gear materials have 17 crnimo6, 15 crni6, 20 crni2moa, 17 cr2ni2moa etc., usually adopt the method of the final heat treatment, carburizing and quenching; Internal gear material for 42 crmoa, 34 cr2ni2moa etc, usually using nitriding process or high frequency quenching process.
Denon company has a number of technology patents, solved the nitriding and carburizing and quenching technology and existing problem, heat treatment equipment in energy saving, high efficiency, environmental protection, safe and reliable, etc have made great progress. Large controlled atmosphere well type carburizing furnace production line, controlled atmosphere multi-purpose furnace line, controllable atmosphere nitriding furnace line, has been listed in the first batch of China heat treatment industry association recommend key promotion product energy saving and emission reduction.
According to technology needs of wind power gear heat treatment, we have to meteorological tooth, zhenhua heavy industries, hangzhou advance gearbox group co., LTD., dongfang turbine co., LTD., ningbo east force transmission equipment co., LTD. Offers a large controlled atmosphere well type carburizing furnace production line, large controlled box type carburizing furnace production line, controlled atmosphere bell type nitriding furnace, controlled atmosphere box nitriding furnace production line equipment, etc. Look from the operation condition of field devices, temperature and atmosphere control stability, high precision and reliable equipment operation. Key components are all made of foreign products, to ensure that the controlled atmosphere carburizing furnace temperature uniformity equipment control at + / - 5 ℃, the carbon potential evenness control at 0.02%; Controlled atmosphere nitriding furnace temperature uniformity control in the plus or minus 3 ℃, the nitrogen potential stability control in K N + / - 0.02; The treatment of wind power gear surface hardness, metallographic organization, heat treatment, hardening layer indicators fully meet the requirements of product design technology.
As of the first half of 2009, the company's total output than the same period last year growth of 40%, in the context of global economic situation is generally bad, denon company risen instead, development prospect is bright. In April 2009, the dragon company is responsible for the drafting of the "big well controlled atmosphere carburizing furnace production line heat treatment technical conditions" industry standard, passed the national standardization technical committee review heat treatment. In August 2009, large controlled atmosphere well type carburizing furnace, controlled atmosphere nitriding furnace hood type two products was identified as high-tech products in jiangsu province. Company's new phase ii of nearly 7000 m2 workshop put into use is nearing completion, and the future development for the company laid a good foundation.
