Causes cold mill strip off with what? How to deal with post-break? A: The cause broken with the following aspects in the rolling process reasons: 1) incoming reasons. Incoming serious quality defects, such as scrap pressed into serious spill and serious side owe pickling acid or too seriously uneven thickness, shape edge wave or waves can cause broken belt in the middle. 2) equipment failure. Electrical, hydraulic control system failure or system failure, a common tension fluctuation, the tension disappears, parking and other hydraulic systems. 3) operational failure. Breaking with the operation caused by the accident is more common, such as found wandering the strip, incoming defects not slow down or stop in time; the choice is unreasonable plan passes, pass deformation is too large, resulting in rolling pressure, plate-shaped difficult to control, before the pass, after much tension, pull off the strip; strip passes before somewhere thickness fluctuations (thinning or thick), after the pass or will not slow down in time tension control off, causing broken belt and so on. 4) Roll burst causing broken belt, belt, it should immediately stop, pull the rack strip and work rolls, intermediate rolls pull the steel cutting machine, check the work rolls, intermediate roller is sticky roller or damage, slightly sticky rolls available Whetstone polished steel surface cutting machine parameters, serious damage, should be replaced by back-up rolls. Also off the band must be cleaned of debris racks, if rolling off the main drive shaft safety loop mechanical personnel should be notified immediately replace the safety ring, or can not roll out of work. It may be necessary to open the injection emulsion, and the residue washed clean in a rack Suixiao strip. After replacing the rollers, open the first volume of steel rolling speed is not too fast, and carefully check the quality of its surface. The new cold-rolled steel costal mechanical devices include the following: 1, put the wire cage: Hot plate round cage warp straight blasting machine 2, blasting machine: a group of three to a pulley, wire drawing machine driven by heat Rolling through a set of pulleys coiled repeatedly bent, broken skin rust off and rust. 3, the main mill: The machine is driven for two three-roll cold rolling head, three roll into each other 120 ° angle, with the center pair. The main role of the first group of the mill is reducing, the role of the second group is reducing mill and cotton gin. According machining diameter and reduction, adjust the pass-sectional shape and size rebar. Structural adjustment linkage can also be adjusted individually. 4, pull the disc machine: This machine electromagnetic speed motor-driven, multi-stage gear drive cabinets to the spindle and multi-line drum, traction steel operation, is the main driving force mechanism of production lines. Motor speed can be adjusted to change the rolling speed. According to the size of the rolled steel bar diameter cutting machine price, you can adapt to a variety of products. 5, stress relief machine: consisting of a plurality of rollers, finished multi-channel moderately repeated bending, pulling rolling process to eliminate internal stress of finished steel shears machine, increase the elongation finished. 6, close-ray machine: up machine for word round-ray machine, word round closing line reel weighs 0.7-2 tons, freely chosen by the production unit price of steel cutting machine, steel cutting machine, energy efficient - Rugged Durable provided by Zhengzhou City, China Metallurgical Machinery Manufacturing Co., Ltd. Zhengzhou City, China Metallurgical Machinery Manufacturing Co., Ltd.
