 Henan MCC - Notes costal cold rolling mill roll changing time! For costal cold rolling mill customers, in order to ensure product quality and meet different production needs, in the production process often requires frequent downtime for costal cold rolling machine roll change jobs. Some customers because anxious steel bending machine equipment, in the process leading to the roll change operatives personal injury, resulting in a very bad influence. So precautions when cold rolling mill roll changing down, what does? On this issue, Gongyi City Metallurgical Machinery Company costal cold rolling mill and technical personnel for you to fully analyze, answer it. Metallurgical Machinery Company costal cold rolling mill technicians believe costal cold rolling mill roll change down when there are so few links need extra attention before the roll change, roll change and after roll change, these three sectors Notes as follows: First, the costal cold rolling mill downtime precautions before ① roll change before changing the roll must be ready for anything to work, used to have to change tools and spreader rolls should be carefully checked and found problems in time. ② When cold rolling mill equipment is not completely stopped, prohibited roll change. ③ in the process of cold rolling machine roll change, there should be someone to command. ④ roll under demolition can not just pile up (especially hot rollers), so as not to affect the staff channel. ⑤ To prevent wounding roll rolling, cold rolling mill roll stacking height should not exceed three. (4) cold rolling mill strip rolling mill equipment has good mechanical properties and process performance (such as high strength, low yield limit, good deep drawing properties, etc.). (5) enables high-speed rolling and the completely continuous rolling, with high productivity. Cold-rolled strip steel rolling equipment production methods are there? Cold-rolled steel strip production method is divided into two monolithic rolling and roll method. Monolithic rolling. The earliest use of monolithic two-roll rolling mill equipment, the multi-purpose four-roll cold rolling mill equipment. Four-roller cold rolling mill rolls its rotation direction can be divided into reversible and non-reversible. When using irreversible four-roll mill chip production, rolling operation is manually fed one by the steel rolling production line equipment steel bending machine, cold rolling mill rolls a whole stack of finished steel rebar bender pictures times, with before lifting crane to stack the board mill, rolling under a second, and so cycle, until such time as the provisions rolled into finished size. When using reversible rolling equipment, the rolling operation, there are two, one is rolling back and forth every piece of steel on steel rolling equipment, rolling up into a final product size, and then the second steel rolling. This method of operation, although the adjustment operation frequently depressed steel bending machine, but the product is easy to scratch the surface, so the actual production application more, especially larger rolling unit weight and size of the plate, are used in this method. Another is fed by one per plate rolling equipment, pending a full stack of finished rolled steel plate after a time, and then return to the rolling one by the second pass. Such methods of operation so that the rolled product more uniform size, and eliminating the need for roll reversal and pressure adjustment time, thus a higher cold rolling mill production, but between the plate surface can sometimes cause scratches. Single rolling method can not be used due to the tension, so each pass reduction rate is generally not more than 14%, increase in rolling passes, plus cold-rolled steel mechanic hardening increases. Therefore, the thickness of the thin sheet rolling can not produce cold rolled products. Roll rolling.
