Preparation method of environment-friendly stemming for submerged arc furnace
The invention discloses a preparation method of environment-friendly stemming for a submerged arc furnace, and relates to the technical field of refractory materials, the preparation method comprises the following steps: using a heating pipe to preheat a stemming mill, adding aggregate into the stemming mill for milling, injecting a liquid binding agent, then continuing mixing and milling, adding powder into the stemming mill for mixing and milling, and obtaining the environment-friendly stemming for the submerged arc furnace. And conveying the mixed and ground materials into a forming machine, and carrying out extrusion forming to obtain the environment-friendly stemming. According to the environment-friendly stemming disclosed by the invention, a high-melting-point solid solution can be formed on an interface layer of slag and the stemming, so that the contact between the slag at a slag notch of a submerged arc furnace and the stemming is effectively prevented, the permeation and erosion rates of the slag to the stemming are reduced, and the stemming has high-quality erosion resistance and is beneficial to maintaining the stability of the slag notch.
本发明公开了一种矿热炉用环保炮泥的制备方法，涉及耐火材料技术领域，制备方法如下：使用加热管对碾泥机进行预热，将骨料加入到碾泥机中进行碾磨，注入液体结合剂后继续混碾，再将粉料加入到碾泥机中进行混碾，将混碾后的物料输送至成型机中，经挤压成型，即可得到环保炮泥。本发明中的环保炮泥，可以在熔渣和炮泥的界面层形成高熔点的固溶体，有效阻碍了矿热炉渣口的熔渣与炮泥的接触，降低了熔渣对炮泥的渗透、侵蚀速率，使得炮泥具有优质的抗侵蚀性能，有助于维护渣口的稳定。
