Problems solved by technology

[0006] 10-15% of the turning material will be produced during the stopper turning process, and the turning material will be used as the leftover material after the stopper processing, all of which will be treated as industrial waste, resulting in waste of resources and industrial solid waste pollution
[0007] Waste skateboard bricks are the products of steelmaking ladles, all of which are treated as industrial waste and cannot be effectively utilized, causing solid waste pollution to the environment

Abstract

The invention discloses a method for compositing and producing a tundish impact plate through combination of a stopper turning material and a waste sliding plate. According to the method, a waste sliding plate brick and the stopper turning material are introduced into the impact plate, sliding plate granules and stopper granules are obtained through secondary processing, tabular corundum in the recycled sliding plate is taken as an aggregate and is combined with a certain amount of aluminum-rich spinel of the stopper turning material, the high-temperature flushing resistance of corundum particles and the slag corrosion resistance of the aluminum-rich spinel are adequately utilized and effectively combined, and the novel tundish impact plate is produced by virtue of thermoplastic phenolic resin, so that the flushing resistance and corrosion resistance of the impact plate in the high-temperature use process are improved, the safety of the impact plate is substantially improved, and the service life of the impact plate is substantially prolonged; the flushing resistance, corrosion resistance and thermal shock resistance of the produced tundish impact plate are superior to existing products in the use process, the circular and efficient utilization of waste refractory materials is realized, the regeneration of resources is realized, the energy is saved, the environment is protected, and the social benefit is obvious.

Description

technical field [0001] The invention belongs to the field of refractory materials, and relates to a recycling technology and a processing method for waste materials, in particular to a method for compositely producing impact plates using recycled stopper turning materials and waste skateboard bricks. Background technique [0002] The stopper turning material used in the present invention is mainly the discarded turning material produced in the process of stopper turning, the main purpose of the stopper is flow control in iron and steel smelting continuous casting tundish, and the material is mainly corundum spinel. [0003] The waste skateboard used is mainly the waste skateboard brick used for recycling the steel ladle lining used in iron and steel smelting. The main purpose of the skateboard brick is a part of the ladle molten steel flow control device, which controls the closing of the molten steel during the casting process. The material is mainly Tabular alumina, graphi...
