Ningde welded pipe equipment, strong support for the three subjects of stainless steel machinery 

 "Chenzhou three subjects Steel Co., Ltd." was established in 1993, is dedicated to high-end stainless steel tube equipment developed high-tech enterprise, the company has a number of self-developed patents, also passed the ISO9001 quality management system certification and the company with independent import and export rights. "Respectively" product because of its superior performance, high-quality cost-effective, chasing in the industry, far ahead, a number of large syndicated corporate and powerful state-owned enterprises are our long-term customers, and because the product has a high good quality so that the "three subjects' well-known overseas products, products sold: Malaysia, Taiwan, Vietnam, Bangladesh, Kenya, Russia and other countries with foreign high-end products competing against. With the continuous development of the company in 2009, "Steel Co., Chenzhou three subjects" more phase of Foshan location and mature market in Foshan Nanhai Luo village set up a "three subjects the company Foshan factory" allow the company to further influence to expand. 
 "Respectively" product groups according to the different needs of the customer segments targeted a "stainless steel decorative tube machine" and "stainless steel industrial tube machine", and then combined the customer's actual situation and then subdivided from the two series a "high-end machine", "precision machine", "ordinary machines" three grades to meet the different needs of customers. "Respectively" equipment specifications vary, pipe from ￠ 6 ~ ￠ 325, thickness from 0.2mm ~ 8mm. Mold, polishing machine, embossing machine, the leveling machine, annealing equipment and other equipment the company readily available to provide customers with full service head to the tail of the sound, so that customer does not have to worry about. 
 We always adhere to "focus on quality, creating value for customers" business philosophy! Warmly welcome colleagues sincere cooperation and common development! 
 The following is the promotion of the article, has nothing to do with the company 



 Formed on the grain boundary layer of crust that had a lot of brittle steel, industry reticular distribution. Hinder the plastic deformation of steel, quenching generated when under great stress caused by quenching cracks. Prevent overheating parts cracks due to hardening of the main measures ① craft reasonable to make the right temperature and heating 

 High-speed steel should be taken to lower the quenching temperature, heating method. Such as the large size of some of the more serious carbide segregation high-speed steel cutting tools. To ensure plenty of heating, the heating time may be extended, for some parts with sharp corners should be farther away from the furnace heater, salt bath furnace parts not less than the distance from the electrode 

 Ensure the instrument is always in operation, under normal use conditions. Instrument to ensure that members of temperature, set temperature, the thermostat accurate at the time. ③ work hardening furnace should always observe the intermediate case, 50mm sharp corners to avoid overheating. ② the Thermometer and temperature instrumentation to regularly check the proof and maintenance. Found to have abnormal changes in furnace temperature 

 Time to find a craft or instrument and other relevant staff members to resolve, when. Necessary to immediately stop production, re-temperature, furnace temperature back to normal until after the production. ④ equipment to ensure that the process requirements. Pieces of non-reducing carburizing martensite measures are: 1 as far as possible with low-carbon hydrocarbons and preparation of high purity gas carburizing gases do
