Pipe production from continuous-cast high-alloy steel blanks

Experiments are conducted on pipe production from continuous-cast billet made of TP 304L and TP 316L corrosion-resistant steel from various suppliers. A wide range of pipe is industrially produced by hot pressing and cold and hot rolling. Assessment of pipe quality shows compliance with the relevant standards.     

The transformation of defects in continuous-cast semifinished products into surface defects on rolled products

The rolling of steel transforms certain defects formed during the steelmaking operation into other, outwardly similar defects (such as blowholes, longitudinal cracks, and folds). Like steelmaking defects, the defects formed during rolling cannot always be unambiguously evaluated by visual inspection and distinguished from the flaws formed during production of the steel. For example, it is sometimes difficult to distinguish laps from rolled-in cracks or to distinguish rolled-in scabs from folds. Accurate classification of surface defects on rolled products according to their causes and the stage of the production process in which they were formed is essential to improving product quality and reducing the cost of producing steel and rolled products, since it makes it possible to promptly make corrections to the process. The degree of accuracy with which the origin of a given defect is determined depends on the degree of perfection and reliability of the inspection methods and equipment used, as well as on the system implemented to monitor the production process. __________ Translated from Metallurg, No. 2, pp. 60–64, February, 2006.

Production of continuous-cast slabs from low-silicon steel

At OAO Chelyabinskii Metallurgicheskii Kombinat, a production technology for high-quality, low-carbon, and low-silicon steel capable of deep extrusion (08У, 18УA, 08πc and similar steel) has been developed and introduced. Continuous-cast slabs are produced by means of the following system: an arc furnace, a ladle-furnace unit, and a continuous-casting machine. Appropriate engineering measured for the production of such steel slabs have been developed.     

Modelling the process of gas casting for the production of housing parts from tubular semifinished products

An example is given of the use of a technology developed by the Moscow State Institute of Steel and Alloys to make parts of housings from tubes (alloy Zn-22% Al) of rectangular cross section under superplastic conditions. The technology employs gasostatic casting.
