Tundish environment-friendly dry material and preparation method thereof
The invention relates to the technical field of tundish environment-friendly dry materials, and discloses a tundish environment-friendly dry material and a preparation method thereof. The tundish environment-friendly dry material is prepared by taking forsterite as aggregate and fused magnesite as fine powder, adding a proper amount of non-resin binding agent and additive and mixing, and due to the use of the non-resin binding agent, the environment-friendly dry material does not generate pungent smell during high-temperature baking, is environment-friendly, and can be used for preparing the tundish environment-friendly dry material. The dry type material does not threaten the health of operators, hydrogen increasing and recarburization effects on molten steel are not generated due to the fact that the dry type material is low in hydrogen content and does not contain carbon elements, the defects of air holes, white spots and the like generated in the casting production process can be avoided, the compactness of castings is remarkably improved, and the yield of the castings is increased; and the service life is more remarkable.
本发明涉及中间包环保干式料技术领域，公开了一种中间包环保干式料及其制备方法。该种中间包环保干式料以镁橄榄石为骨料，以电熔镁砂为细粉，加入适量的非树脂型结合剂与外加剂，通过混合后制备而成，由于其中使用了非树脂型结合剂，所以该环保干式料在高温烘烤时不产生刺激性气味，对环境友好，不会对作业人员的健康带来威胁，由于其中氢含量少且不含有碳元素所以不会对钢水产生增氢与增碳的作用，能够避免铸件生产过程中产生气孔白点等缺陷，显著增强铸件的致密性，提升铸件的良品率，使用该干式料制备出来的中间包，绿色环保具有更为显著的使用寿命。
