The submerged entry nozzle continuous casting protects the liquid steel from being oxidized by the ambient air when it flows into the crystallizer from the tundish.
Mullite insulating brick made by CH refractories is JM series according to international standard. Because jm23 insulation brick with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package mullite insulating brick with special packages to protect mullite bricks from damage.
The high strength castable refractory steel fiber reinforced wear-resistant castable is prepared by adding special grade aluminum bauxite clinker or corundum as aggregate and powder, adding binder, admixture and heat-resistant stainless steel fiber.
