Abstract

The invention provides novel environment-friendly dust suppression stuffing sand which comprises the following components in parts by weight: 92-104 parts of quartz sand; 2-4 parts of carbon black powder; 3-6 parts of low density polyethylene particles; wherein at least part of the carbon black powder is adsorbed on the surfaces of the low-density polyethylene particles or dispersed in the low-density polyethylene particles. Through the special quartz sand particle size combination, the special method is adopted for preparing and adding the density polyethylene particles, so that the stuffing sand disclosed by the invention has excellent sintering performance, has good flowing property during use, and is free of black smoke and flying dust; and the material can be rapidly sintered at high temperature, has excellent molten steel penetration resistance, and avoids low automatic casting rate caused by an over-thick sintering layer.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting and casting, and in particular relates to a novel environment-friendly dust suppression and drainage sand and a preparation method thereof. Background technique [0002] With the development of industrialization in our country, the demand for high-quality steel continues to grow. At the same time, as the country pays more attention to environmental quality, the supervision of steel plant pollution is more stringent, and higher requirements are placed on the environmental protection of the steelmaking process. In the ladle refining process, the role of ladle drainage sand is very important, and the performance of drainage sand is one of the main factors affecting the automatic pouring rate of ladle. High-quality drainage sand can greatly improve the production efficiency of continuous casting, reduce refining energy consumption, and improve the competitiveness of steel mills. ...
