Case of bulk supply of drum gear couplings by CITIC Steel Group Professional transmission solutions: Single supply over 1,000 pieces; Quality guaranteed |
| The cooperative client, CITIC Steel Group Co., LTD., supplies the drum gear coupling (customized model) with a supply quantity of 1,200 pieces (single batch delivery). The application scenarios include steel rolling production lines and heavy machinery transmission systems |
Project background and customer requirements
As a leading steel producer in China, CITIC Steel Group urgently needs a batch of high-performance drum gear couplings to connect the main drive system of the steel rolling mill to meet the capacity expansion and renovation requirements of its new factory's steel rolling production line. The couplings are required to be capable of withstanding high-intensity torque and impact loads.
Batch demand: Purchase more than 1,000 pieces at a time, and delivery must be completed within 45 days
Performance requirements: It must withstand a maximum torque of 8000N·m and operate within a temperature range of -20℃ to 120℃
Accuracy standard: Conforms to GB/T 10095-2008 Grade 6 accuracy, tooth surface hardness HRC58-62
Special requirements: Possess excellent axial, radial and angular compensation capabilities, and be adaptable to heavy-duty working conditions
Customized solutions 1. Customized product design According to the working conditions of the steel rolling mill, the parameters of the drum-shaped tooth profile are optimized. 42CrMo alloy structural steel is used for integral forging, and the tooth surface is carburized and quenched to enhance wear resistance and impact resistance. Design special lubrication channels to extend the maintenance cycle to 1.5 times that of traditional products. 2. Mass production guarantee Activate the emergency production plan, allocate 8 specialized production lines, and implement a 24-hour three-shift production system. Establish a full-process quality control system. Conduct 100% tooth surface accuracy inspection and torque testing for each batch of products to ensure product consistency. 3. Efficiently deliver services Formulate a phased delivery plan. Complete the delivery of 500 pieces in the first month, and deliver all the remaining 700 pieces by the 40th day. Professional installation guidance and technical training are provided as a package to ensure that the equipment is quickly debugged and put into place. |
Project outcome 100% on-time delivery rate, 99.8% product qualification rate, 15% reduced equipment energy consumptionAll 1,200 drum gear couplings have been accepted by the quality inspection department of CITIC Steel Group. They have been installed and put into operation for 18 months, and none of them have had quality problems. The stability of equipment operation has significantly improved, and the maintenance cost has been reduced by about 30%, which has been highly recognized by the customer. |
Customer review The drum gear couplings purchased this time exceeded expectations in both batch delivery capacity and product quality. All 1,200 products were delivered on time, and the inspection pass rate was as high as 99.8%. Under the high-intensity operating environment of the steel rolling production line, couplings have demonstrated excellent stability and durability, effectively ensuring our production efficiency. We look forward to further deepening cooperation in the future and establishing a long-term strategic partnership. - Director Wang of the Equipment Department of CITIC Steel Group |
