Preparation method of thermal insulation layer material and steel ladle using material as thermal insulation layer
The invention discloses a preparation method of a thermal insulation layer material. The preparation method comprises the steps of: S1, placing inorganic particles in an acetone solution, carrying out ultrasonic cleaning for 5 min, carrying out filtration washing with deionized water, and carrying out vacuum drying for spare; S2, putting 50-80 parts of inorganic particles, 0.5-3 parts of a flame retardant, 10-30 parts of a binder, 5-20 parts of an opacifying agent and 3-7 parts of a fiber reinforcement into a stirrer, and conducting stirring and mixing for 10-30 min to obtain a mixture; S3, putting the obtained mixture into a mold, feeding the mixture into a pressing machine, and carrying out compression molding at the set pressure of 1-20 MPa for the pressure maintaining time 15-40 min, and then conducting demolding to obtain a preset fiberboard; and S4, putting the preset fiberboard into a drying oven for high-temperature treatment at the temperature ranging from 90 DEG C to 200 DEG C for the time ranging from 8 h to 12 h, so as to obtain a thermal insulation layer material. The invention discloses a steel ladle. The steel ladle comprises a shell, a heat preservation layer arranged on the surface of the inner side of the shell, a pouring material covering the heat preservation layer, and refractory bricks laid on the castable. The anti-pressure capability is high, and the heat preservation layer can be effectively prevented from being pressed and pulverized.
本发明公开了一种保温层材料制备方法，包括以下步骤：S1：将无机粒子放入丙酮溶液，超声清洗5min后，用去离子水滤洗，真空干燥后备用；S2：将无机粒子50‑80份、阻燃剂0.5‑3份、粘结剂10‑30份、遮光剂5‑20份、纤维增强体3‑7份放入搅拌机搅拌混合10‑30min，得到混合料；S3：将所得混合料放入模具，上压机，压制成型，所设压力为1‑20MPa；保压时间为15‑40min脱模后，得到预置纤维板；S4：将所述预置纤维板放入烘箱经行高温处理，温度为90‑200度，时间为8‑12h，得到保温层材料本发明公开了一种钢包，包括：壳体；保温层，所述保温层设置在所述壳体内侧的表面上；浇注料，所述浇注料覆盖在所述保温层上；耐火砖，所述耐火砖铺设在所述浇注料上。其抗压能力较强，能够有效防止保温层受压粉化。
