We all know that cold wire drawing is actually a kind of wire, it is mainly reinforced through a series of processes such as peeling the production of wire, mainly metal cold processing technology.Due to the high strength of cold wire drawing, more commonly used in the construction, can reinforce the quality of the building.Production of cold wire drawing process, should pay attention to the following points, the following by the cold wire drawing factory flame Xin Sen domain to introduce.
1, cold drawing cold tensile stress control: according to the different types of Steel, after the cold drawing process, for pretension prestressed steel used, it must be carried out to control the cold tensile stress, if the maximum cold tensile rate exceeds the specified value, it will also be a certain mechanical energy experiments.
2, Cold drawing cold drawing rate measurement control: if you want to control the rate of Cold Steel cold drawing, the control value to be determined by the relevant experimental values.Test assay requirements for each batch of test specimen can not be less than four, and each specimen should be required to carry out the appropriate cold tensile stress test to determine the cold pull rate, and finally take the average of the test piece as the furnace the actual batch of steel cold pull rate. In addition, if the steel strength is high, the average cold pull rate is less than 1%, when the steel cold pull, still by 1% of the cold pull rate control.
3, cold drawing cold drawing speed control: in the process of cold drawing, we want to make steel fully deformed, it is necessary to control the speed of cold drawing, generally 0.5-1.0 is appropriate.And after the cold to the specified stress and cold pull rate, should immediately stop pulling, and relax the steel, Steel fully deformed to the time.
Cold wire drawing production need to pay attention to the small make up today for everyone to introduce here, if you are interested in our content, you can browse our website or consult our online customer service, we will be happy to serve you.
