New developments for continuous pouring of steel are considered, including slide gates, refractories, promis
ing technologies, etc. A comparative analysis of the designs of domestic and foreign manufacturers is given
and the basic operating characteristics and criteria for the selection of refractory slabs for slide gates are pre
sented. The latest developments from NPP Vulkan-TM related to the creation of equipment for continuous
casting of steel are considered.

The widespread application of the method of continu-
ous-continuous casting and highly durable refractory materi-
als has greatly increased the requirements imposed on the
rate of turn-over of teeming ladles and for reduced service
times and has entailed the use of modern slide casting sys-
tems to enable increases in the level of automation of the
processes involving in casting of metal and reductions in the
unit costs for these processes. To solve this problem it is nec-
essary to select an efficient design of a slide valve system
and arrive at an optimal choice of the consumable refractory
set. From an analysis of the evolution of the development of
slide valve systems it becomes possible to formulate the re
quirements that have to be imposed on the new generation of
slide valve systems to achieve highly productive multi
ple-strand continuous seal casting:
– multipoint spring-actuated mechanism for uniform
compression of refractory slabs;
– elevated lifetime of components and parts of the system;
– the presence of a system for clamping of the refractory
– minimization of the human factor in operation of the
– rapidity and ease of replacement of refractory materials.
The use of modern designs enables us to achieve a high
degree of uniformity in the application of a clamping force to
refractory slabs, ensure their automatic adjustment, compen
sate for cyclic thermal expansions and wear of the refractory
