Refractory plates (Options) and slide gate ladles

摘要

The invention relates to metallurgy, in particular to the structure of refractory products for continuous casting of steel and other molten metals, slide gates and constructions in which data items are used. The technical result consists in the creation of five variations refractory plates with enhanced operational capabilities, providing multiple metal casting through one set of plates and an increased service life, and also - to further improve the reliability of the plates due to their ability to withstand the repetitive thermal expansions in several casting. Additionally, the gate valve is created, designed to work with refractory plates mentioned above on several casting without replacement. For this purpose in the refractory plate comprising a base made of high resistant refractory material and work with the contact planes and a metal band with the positioning projections disposed on the side surface of the base plate, positioning projections shroud adapted to further compensation for thermal expansion. Or, the positioning projections of the metal band are arranged to the subsequent compensation of thermal expansion, wherein the plate is provided with a centering device in the form of at least one pair of retaining grooves disposed on an edge of the band on either side of the longitudinal axis of the plate from the contact plane of its base and adapted to contact with stops corresponding seat mounting plate or slide gate valve. Or, the positioning projections of the metal band are arranged to the subsequent compensation of thermal expansion, wherein the plate is provided with a centering device formed; in the form of at least one pair of detents formed in the form of additional protrusions on the side portions of the belt located on both sides of the longitudinal axis of the plate and adapted to contact with the locking holes corresponding seat mounting plate or slide gate valve. Or, the refractory plate provided with a centering device in the form of at least one pair of retaining grooves disposed on the belt edge on both sides of the longitudinal axis of the plate from the contact plane of its base, and adapted to contact with stops corresponding mounting plate nests carriage or slide gate. Or, the refractory plate provided with a centering device in the form of at least one pair of detents formed in the form of additional protrusions on the side portions of the belt located on both sides of the longitudinal axis of the plate and adapted to contact with the fixing holes of the corresponding mounting slot plate or the carriage slide gate. Slide gate casting ladle, comprising a mounting plate and / or carriage with the socket, inside which is placed a refractory plate with a metal shroud mounting plate slot and / or a carriage provided with clamps or the fixing holes arranged at the edges of the socket on both sides of the longitudinal mounting axis of the plate and / or a carriage adapted to engage with corresponding locking grooves or metallic shroud retainers refractory plate which is made according to any of the above second to fifth options for the utility model. 6N. 27 and ZP f-ly; 24 yl.
