Slag dam for tundish and preparation method of slag dam
The invention belongs to the technical field of refractory materials, and discloses a slag dam for a tundish and a preparation method thereof.The slag dam for the tundish comprises, by weight, 30%-38% of raw forsterite with the particle size being 15-8 mm, 5%-15% of regenerated magnesium aluminate spinel with the particle size being 5-3 mm, 10%-25% of regenerated magnesium aluminate spinel with the particle size being 3-1 mm, 10%-20% of fused magnesite with the particle size being 1-0 mm and 10%-20% of fused magnesite with the particle size being 180 meshes. 2-8% of light calcined magnesia powder with a particle size of 1000 meshes, 1-5% of silicon carbide with a particle size of less than 240 meshes, and 2-6% of silica fume with a particle size of less than The dispersing agent accounts for 0.1%-0.15% of the total weight of the raw materials, the retarder accounts for 0.01%-0.02% of the total weight of the raw materials, and the explosion-proof fiber accounts for 0.06%-0.08% of the total weight of the raw The slag dam for the tundish is low in cost, small in water adding amount, good in slag resistance, resistant to scouring and long in service life.
本发明属于耐火材料技术领域，公开了一种中间包用挡渣堰及其制备方法，中间包用挡渣堰包括以下重量百分比各组分：粒径15～8mm生镁橄榄石30～38％,粒径5～3mm再生镁铝尖晶石5～15％,粒径3～1mm再生镁铝尖晶石10～25％,粒径1～0mm电熔镁砂10～20％,粒径180目电熔镁砂10～20％,粒径1000目轻烧氧化镁粉2～8％,粒径＜240目碳化硅1～5％,粒径＜2μm硅灰2～6％；以及占上述原料总重量0.1％～0.15％的分散剂、0.01％～0.02％的缓凝剂和0.06％～0.08％的防爆纤维。本发明中间包用挡渣堰成本低、加水量少、抗渣性能好、耐冲刷和使用寿命高。
