Rolling belt breakage prevention system for continuous rolling of high-carbon steel and control method thereof

Abstract

The invention discloses a rolling belt breakage prevention system for continuous rolling of high-carbon steel. At least two rolling mills are arranged at a rolling mill section of an acid rolling mill group, a tensiometer roller in contact with a product is arranged at an outlet of each rolling mill, the lower portions of an operation side bearing seat and a transmission side bearing seat of each tensiometer roller are each provided with a tension sensor, and the tension sensors output an induction signal to control equipment. According to the rolling belt breakage prevention system and method for continuous rolling of high-carbon steel, the occurrence of belt breakage during continuous rolling of the high-carbon steel can be reduced, meanwhile, the efficiency and the cost of continuous rolling of the high-carbon steel are improved, batch production of the high-carbon steel on a continuous rolling mill is realized, and the belt breakage rate is reduced within 3%.

Description

technical field [0001] The invention relates to the technical field of steel rolling. Background technique [0002] The pickling line is a fully continuous high-speed production line. The rolling steel range is: hot-rolled low-carbon steel, ultra-low carbon steel, low-alloy high-strength steel, medium and low grade non-oriented electrical steel, etc. Due to the high alloying elements such as carbon and manganese, high carbon steel is difficult to weld and roll, and it has exceeded the product design outline of continuous pickling and rolling mills. The main alloy elements of some high carbon steel grades are as follows: [0003] [0004] When starting to produce high carbon steel such as 50-2, 65Mn-1, 65Mn-2, 65Mn-3, etc., due to the poor shape and high strength of the raw material, the rolling force during the rolling mill is large, and the rolling runs all over. , and there is no effective means to control, resulting in frequent rolling and broken strips. SUMMARY OF ...
