Embodiment Construction

[0012] The aluminum (zirconium) carbon long nozzle, submerged nozzle and integral stopper refractory product for continuous casting of the present invention will be described in more detail below in conjunction with the examples.

[0013] The aluminum (zirconium) carbon long nozzle, submerged nozzle and integral stopper refractory products for continuous casting of the present invention are made of corundum, flake graphite, light-burned alumina, fused zirconia mullite, fused stabilized zirconia, and silicon carbide Several or all of metal silicon are used as raw materials, and phenolic resin is used as adhesive. First, modify the phenolic resin by adding an anti-burning agent; then make the modified phenolic resin and raw materials such as corundum, flake graphite, light-burned alumina, fused zirconia mullite, fused stabilized zirconia, silicon carbide, and metal silicon powder. Granules or mixed materials; put into abrasive molds for cold isostatic pressing; after drying, lat...

Abstract

Aluminium (zirconium)-carbon long nozzle, submerged entry nozzle and monolithic stopper refractory products for continuous casting are prepared by taking corundum, flake graphite, light-burnt alumina, fused mullite-zirconia, fused stabilized zirconia, silicon carbide and silicon powder as the raw refractory materials and phenolic resins as the adhesives through the procedures of material mixing, cold isostatic pressing, fine lathing and anti-oxidization coating spreading. The refractory products dispense with the high-temperature burning process, lower the cost per ton, reduce the labor intensity and speed up the processing cycle.

Description

technical field [0001] The invention relates to continuous casting technology, in particular to an aluminum (zirconium) carbon long nozzle, a submerged nozzle and an integral stopper refractory product for continuous casting. Background technique [0002] In the continuous casting process, consumables such as long nozzles, submerged nozzles and integral stoppers are needed. In the traditional technology, these consumables are fired at high temperature. The production process consumes high energy, the product yield is low, and the size The problem of poor precision. Contents of the invention [0003] In order to make up for the above shortcomings, the present invention provides an aluminum (zirconium) carbon long nozzle, submerged nozzle and integral stopper refractory product for continuous casting without firing. [0004] Aluminum (zirconium) carbon long nozzles, submerged nozzles and integral stopper refractory products for continuous casting of the present invention in...
