Expanding the technological capabilities of the twin roll casting machine.

Abstract

urrently, one of the most promising areas of metallurgy development is the creation of foundry and rolling complexes based on twin roll casting machines. Their application makes it possible to organize the economical production of high-quality strips of stainless and alloy steels for critical purposes. Despite the existing experience in the creation and development of such equipment in Russia, domestic developments are still inferior to the foreign level. Thus, there is an urgent need to continue work on this topic and to create domestic industrial equipment, taking into account the latest technical solutions. At the same time, the technological capabilities of twin-roll casting machines both here and abroad are not fully used. The specialists of JSC AHK VNIIMETMASH have developed a number of the latest versions of the twin-roller casting machine with advanced technological capabilities. Due to the dosed supply of various reagents into the gap between the casting rolls-crystallizers it is possible to produce steel strips with improved properties, as well as porous aluminium strips, and also composite strips for critical applications. The article discusses the design and technological features of the proposed options for two-roller casting machines.
