Three steel straightening machine _ _ Bar Straightening Machine Metallurgical Machinery

 First, the cold rolling mill maintenance equipment operator job well enough; second, maintenance repairman does not guarantee quality. On the one hand there are some maintenance man is not strong sense of responsibility to deal with sloppy thinking; repairman hand knowledge is not high, the general level of technology is relatively low, and some construction and maintenance equipment specification is not yet clear, so poor maintenance quality. Third, cold rolling mill equipment and spare parts are not ready in time and low quality. Spare parts are not ready in time, it will cause the replacement of spare parts can not change, but to continue to use it to deal with and improvise. Finally, it can not even be forced to deal with parking, repair and longer, more laborious. Quality spare parts also is a big problem. Some cold-rolled ribbed steel plant spare parts into the factory inspection due to lax or strict requirements on when to replace equipment maintenance, because of poor quality, not long and bad, and this is a factor causing frequent maintenance. These are the causes of the cold rolling mill glitches Gongyi City Metallurgical Machinery Manufacturing Co. summary, if you want to make cold rolling mill is always in a state of relatively stable production, then you are using the cold rolling mill production when you have cold rolling mill for routine maintenance, maintenance, and operation method specification cold rolling mill operatives, get ready for a variety of cold rolling mill consumables bar straightening machines, cold rolling mill to prevent the event of failure, customers can timely maintenance of the cold rolling mill. In the test can be tested at any time: ① each inspection lot by the same steel, the same brand, same size and the same level of steel bar straightening machine consisting of equipment, weighing no more than 50t. Mechanical properties shall by disk, by bundles tested. Take two from each plate or test pieces per bundle small bar straightening machine, a tensile test done, do a cold bend test. ② on each plate reinforced if one failed, it is determined that substandard steel plate; steel for each bundle, still doubling sampling retest determination. But also on the quality of cold-rolled ribbed steel bars were first tested in accordance with the following methods: ③ approach of ribbed steel must have a valid certificate of steel straightening machine production line, certificate must be approved by a national or provincial production license Number; reinforced within the certificate to indicate the variety, grade, heat number, quantity, specifications. If it is a copy of the sales unit must be stamped with red chapter, and indicate to the original store. If you can not provide these documents, shall not enter the site. ④ cold-rolled ribbed steel bars approach, the construction unit rewinding staff to control the quality of documentation to verify steel varieties, grades, batch number, heat number, quantity, specifications are consistent with the certificate, inconsistencies are not allowed to discharge, and immediately withdrew. ⑤ visual inspection, cold-rolled ribbed steel bars should be straight, no damage, surface without cracks, folds, scars, ears, oil, flake or granular old rust, allowing local bumps and indentations, concave pits, scratches, pockmarked face, but its depth or height of not more than 0.2mm. Each disk drive must have a full plate as root, ribbed steel surface heat treatment allows the bumps, but shall not exceed the height of the transverse ribs.
