Influence of Uneven Heating Temperature on Steel Rolling Production
Impact of unequal Heating Temperature on Rolling Production
In many cases, in order to obtain higher product quality, the temperature of the billet before it is rolled must be evenly controlled. But when the heating temperature is uneven, a variety of unexpected economic losses will occur. The un......

The role of split guide and guide roll wedge angle in continuous bar rolling
Introduction
In the rolling process of the bar, the role of the guide vane and the guide roll is very important. It is necessary to ensure that the bar shape meets the process requirements during the rolling process. The angle change of the guide blade and the guide roller can effectively control ......

Bundling bars and its Causes and Treatments
Bundling bars, sometimes known as bar marks or bar spots, are dark spots visible on bars of steel, aluminium and other metals. While bundling bars may raise concerns about the quality of metals, this form of discolouration is often harmless and does not......

The Un Eaual Heating of Steel in Rolling
Rolling is a process of metalworking in which metal is passed between one or more pairs of rolls to reduce the thickness and to make the metal workable. It is a heavily used technique that is applied in a wide range of manufacturing applications, including......
Roll Manufacturing Defects
Roll Defects in the Manufacturing Process
Roll defects can arise in the manufacturing process of any product that is formed from a roll, such as paper, film, or sheet metal. These types of defects cause the functional performance of the final product to suffer, and this can have an adverse effect......
rolling pressure
Rolling pressure
Rolling pressure is essential in many mechanics processes, such as welding, forming and other joining processes. It is a term used to refer to the amount of force applied on a material such as metal or a plastic when it is being compacted, reshaped or bent. Rolling pressure is ......
Continuous casting billet distorted shape
The shape of small billet after continuous casting is an important parameter for determining the surface quality of the billet and the production level of a steel plant. When the shape of the billet after continuous casting is not ideal, the subsequent rolling process may have defects such as cold......

Subsidence
Subsidence is a phenomenon in which the surface of the earth compresses downwards or sinks, usually due to the removal or movement of subsurface materials. In engineering, this phenomenon can be a major problem for large infrastructure projects, such as dams, bridges, buildings, highw......
Comprehensive Analysis of the Factors of Billet Surface Defects
Abstract
Steel sheet is an important material for forming finished products in the industrial production process, and its quality directly affects the quality of the finished product. There are many factors that can cause defects in the surface of a steel slab, such as poor lubricating oil, proce......
Reasons for stacking steel at the head during rolling
The use of head-stacking steel in rolling is becoming more and more common in the steel industry, and it can bring many benefits to the production process. This paper will discuss the reasons why head-stacking steel is used in the rolling process, as well as its advantages over other materials.
