| 7. | Sino - foreign joint venture nanjing dongwu metal material co . , ltd . is a hi - tech enterprise which specially produces and sells induction heat oil tempered spring wire and die pusher rod 中外合资南京东吴金属制品有限公司是一家专门生产经营感应加热油淬火-回火弹簧钢丝冷镦钢丝轴承钢丝异形钢丝退火磨光定尺线材冷拉钢丝和模具推杆线材的高新技术企业。 |
| 8. | Founded in september 1997 , the company occupies an area of 35000 square meters and has 50 staffs , including 3 engineers , 2 vice senior engineers and 4 engineers . with the help of some domestic specialists who engaged in the research on induction heated quenching - tempering treatment in weapon and space industries . we developed the first induction heat oil tempered elastic wire production line in china by ourselves . this production line was put use in august 1998 , and was enlisted in the spak programme in 2000 serial number : 369 , programme code : 00b101d691004 创建于1997年9月,占地35000平方米,员工50名,其中研究员级高工3名,高工2名,工程师4名。依靠国内一批在军工企业长期从事感应加热调质处理研究的专家,自行研制成功国内第一条弹性线材感应加热油淬火-回火生产线,并于1998年投产。 |
| 9. | Induction heated oil tempered spring wire is a kind of new technical material which has been developed since 1980s . it can be heated by means of eddy induced into itself through electromagnetic coil and this method is mainly used in surface quenching . with correct designing and reasonable current frequency , induction coil and heat treatment process selected , as well as plc controlling applied , the wire can be uniform heated along cross - sectional and longitudinal direction and can be quenched and tempered continuously 应加热油淬火-回火弹簧钢丝,是二十世纪八十年代发展起来的新技术材料,在国外称为itw induction heat oil tempered spring wire 。是通过线圈电磁感应钢丝本身产生的涡流进行加热,通常主要用于表面淬火。经正确设计,选择电流频率,合理的感应线圈及热处理工艺,并实施plc控制,可使钢丝整个截面及长度上得到均匀加热,进行连续整体淬火和回火。 |
| 10. | Induction heat oil tempered wire and rod can be directly used in the manufacture of spring and pusher and the quenching - tempering process thereafter can be omitted , thus the quality problems such as deformation of workpiece , decarburization , un - stability and un - qualification of mechanical property can be avoided and the quality stability and reliability of product can be improved 感应加热油淬火-回火钢丝及线材,能直接用于绕簧和制造推杆,可省去一般材料绕簧和推杆加工成形后的淬火-回火工序,避免了由此带来的工件变形脱碳及力学性能不稳定甚至不合要求等质量问题,提高了产品的质量稳定性和可靠性。 |
