| description | The invention belongs to the technical field of refractory materials, and particularly relates to a self-curing dry material for a tundish and a preparation method thereof. The dry material disclosedby the invention is prepared from the following components in parts by weight: main materials consisting of 50-95 parts of magnesia, 10-40 parts of forsterite and 10-40 parts of crushed magnesite bricks; auxiliary materials consisting of 0.1-1 part of an explosion-proof agent and 0.5-5 parts of Guangxi white mud; and a binding agent consisting of 2-8 parts of a composite binding agent. By optimizing the composition of the binding agent, traditional phenolic resin can be replaced, and the environment-friendly performance of the material is improved; self-curing of the dry material can be further achieved by optimizing main materials; and the baking link of a working layer with a mold in a traditional dry material construction process is omitted, so time cost is saved, potential safety hazards on site are reduced, e |
