METAL ROLIING PRACTICE

The achievements of modern computer techniques open extensive prospects in the automation of production processes. The application of computers in the control of production processes enables metallurgists to establish optimum parameters in these processes. The application of a continuous operation sequence (rolling, heat treatment, finishing, marking, etc.) is typical of up-to-date rolling departments. Continuous mills enabled metallurgists to automatize the production process and to perform rolling at the highest speeds. In addition to the erection of continuous rolling mills, a large number of continuous pickling, annealing, tinning, galvanising shearing and other production lines are installed.

The most important problem in this field is the economy of metal. Much can be attained by using various designs of light-weight rolled sections as well as by rolling products made to the minus tolerance limits and of higher accuracy.

The development of rolled metal production in Ukraine is characterised by the extension of the type and size ranges of rolled products. Heat treatment of rolled products must be extensively applied. The introduction of heat treatment for hot rolled sheets, plates, sections and tubes of carbon and low-alloy steels will aid in increasing the strength and other desirable properties of the steel.

The quality of rolled products must also be raised by supplying the steel-making plants with more homoge­neous ingot metal, free of harmful impurities. Modern methods must be applied in rolling departments for sur­face conditioning the semifinished product and finishing the end product.

Higher rolling accuracy may be achieved by improving the design of the roll stands of mills, by revising the material and design of the roll bearings, by the application of multiple roll mills (for rolling plate, sheet and strip) and by the development of automatic size control and automatic roll adjustment systems.

Rolled products can be divided into four main groups: (1) steel shapes or sections, (2) plate and sheet steel, (3) special-purpose rolled shapes and (4) tubing.

Steel sections which are widely used in almost all branches of industry can be further classified into general-purpose and special sections. The first group consists of round squares, flats, angles, strip, wire rod, channels, I-beams, and others. In the second group are rails, and special shapes employed in construction, engineering and other fields of industry.
