A brief history of the development of the roll

A brief history of the development of the roll

The variety and manufacturing process of rolls are constantly developing with the advancement of metallurgical technology and the evolution of rolling equipment. Low-strength grey cast iron rolls were used for rolling soft non-ferrous metals in the Middle Ages. In the middle of the 18th century, Britain mastered the production technology of chilled cast iron rolls for rolling steel plates. The progress of European steelmaking technology in the second half of the 19th century required the rolling of larger tonnage ingots, and the strength of either gray cast iron or chilled cast iron rolls could no longer meet the requirements. Ordinary cast steel rolls with a carbon content of 0.4% to 0.6% were born accordingly.

performance requirements

Generally, the main requirements for rough rolls are strength and thermal crack resistance; the work rolls of small 20-high rolling mills weigh only about 100 grams, while the weight of backup rolls of wide and heavy plate rolling mills has exceeded 200 tons. When selecting a roll, first select the main material (various grades of cast iron, cast steel or forged steel, etc.) that can safely bear the roll according to the basic strength requirements of the rolling mill.

Commonly used roll materials and uses are shown in the table. The performance and quality of a roll generally depends on its chemical composition and manufacturing method and can be assessed by its structure, physical and mechanical properties, and the type of residual stress present inside the roll (see roll inspection). The use effect of the roll in the rolling mill depends not only on the material of the roll and its metallurgical quality, but also on the conditions of use, roll design, operation and maintenance. The operating conditions of the rolls of different types of rolling mills are very different, and the factors that cause the differences are: (1) rolling mill conditions. Such as rolling mill type, rolling mill and roll design, pass design, water cooling conditions and bearing types, etc.; (2) rolling conditions such as rolling material varieties, specifications and their deformation resistance, reduction system and temperature system, output requirements and operations, etc.; (3) Requirements for product quality and surface quality, etc.

Roll classification

There are many classification methods of rolls, mainly including: (1) According to the product type, there are strip steel rolls, section steel rolls, wire rolls, etc.; Finishing rolls, etc.; (3) According to the function of the rolls, there are scale breaking rolls, perforation rolls, leveling rolls, etc.; (4) According to the material of the rolls, there are steel rolls, cast iron rolls, carbide rolls, ceramic rolls, etc.; (5) According to The manufacturing methods are divided into casting rolls, forging rolls, surfacing rolls, sleeve rolls, etc.; (6) According to the state of the rolled steel, there are hot rolls and cold rolls. Various classifications can be combined to make the rolls have a clearer meaning, such as centrifugally cast high-chromium cast iron work rolls for hot-rolled strips.

Introduction to some related issues of surfacing rolls

Rolls are the heart of a rolling mill. The use of rolls involves mill selection, roll preparation, maintenance and regular dressing during the rolling process, which are factors that affect mill productivity, product quality and production economics. Since the rolling process is a continuous process, operators need to constantly check the condition of the rolls so that the product can meet the user's requirements for tighter tolerances and surface quality. In order to maintain the competitiveness of the products, it is necessary to constantly ask the mill operators to reduce production costs, i.e. increase the rolling speed, increase the production flexibility of the rolling mill and reduce the consumption of the rolls. So what should we pay attention to when surfacing rolls?
