After months of intense construction, cold drawing heat treatment company based in northern Manchuria, 7 roll straightener reconstruction works are completed, and on June 4 a test successfully . In the cold drawing heat treatment , accompanied by company executives , deputy general manager Wang Huimin and related base head to test the scene . 7 roll straightener is the main body of cold drawing heat treatment equipment company , was acquired in the former Soviet Union in 1957 products . As the new varieties have been unable to fully meet the quenched material 35CrMoA ( size greater than F50mm) the straightening machine and, therefore , drawing heat treatment in support of base leadership , self-financing , on April 20 to begin seven roll straightener Machine transformation . To save money , in addition to some parts from the first steel plant, this source of foundry companies and electrical companies to help the North out of processing , the other more than 200 pieces of all seven parts roll transform the company from the cold drawing heat treatment process itself should be assigned the 200 Number of bolts to pin responsibility for laying all the mechanical engineers and bench technicians to complete . After transformation, 7 roll straightener out of materials extending the system limit of 7.1 m from straightening to 12 meters; size increased from = F100 mm to = F130 mm. The original electrical system of technical improvements , transforming the original simulation system for the all-digital systems, process control to PLC systems, replacement of a higher power motor ( from the original two DC motors 55KW to 72KW), in a certain Extent, solve the new varieties of curvature quenched material difficult to achieve standards. 35CrMoA products from the original three times the average return dropped to Jiao Jiao can be successful again , greatly improved the precision straightening , shortening the production cycle, improve production efficiency, reduce the number of cost indicators .
