Skin-rolling of hot-rolled extra-thin low-carbon steel sheets

نویسندگان

چکیده

Skin-rolling is the final operation of technological process for production auto sheet steel. Tempering affects quality metal surface, properties and stamping ability. Treading allows you to harden surface rolled products keep inner layers undeformed. As a result, it possible prevent formation shear lines during provide an optimal combination mechanical characteristics products. On skin-rolling mills, predetermined thickness. etched sheets provides them with smoother surface. Benefits skin training are increase ability material deep drawing reduce energy costs stamping.The use will allow produce high-quality in accordance requirements standards. An analysis effect on indicators low-carbon steel thin-rolled automotive industry was carried out. The structure hot-rolled extra-thin from 08пс studied. meet ДСТУ 2834-94 cold-rolled Annealing increases its plasticity compared state contributes uniform 2834-94. choice parameters optimization decrease material, improve

The Effect on Rolling Mill of Waviness in Hot Rolled Steel

The edge waviness in hot rolled steel is a common defect. Variables that affect such defect include raw material and machine. These variables are necessary to consider to understand such defect. This research studied the defect of edge waviness for SS 400 of metal sheet manufacture. Defect of metal sheets were divided into two groups. The specimens were investigated on chemical composition and ...

Laser Ultrasonic Characterisation of Rolled Steel Strip: Wave Propagation in Inhomogeneous Thin Sheets

For the production of hot rolled steel it is of special interest to assess the homogeneity of the material along the length of the strip. Being couplant free, laser ultrasound as a method is especially suited for the task because it opens up the opportunity of measuring material parameters early in the production process. Detailed models of the ultrasonic signal are needed though in order to ex...

Low Carbon Steel Sheets Obtained by Reactive Annealing

This paper deals with the possibility of reducing carbon content by heat treatment in reactive atmospheres in order to improve plastic deformations properties of steel sheets. The heat treatment involves a decarburation annealing after a cold rolling, as opposed to the traditional process that performs the heat treatment in non-reactive atmospheres. Some of the most relevant variables were stud...

Statistical discriminator of surface defects on hot rolled steel

A statistical approach to defect detection and discrimination has been applied to the case of hot rolled steel. The probability distribution of pixel intensities has been estimated from a small set of images without defects, and this distribution is used to select pixels with unlikely values as candidates for defects. Discrimination of true defects from random noise pixels is achieved by a dyna...
