Abstract

The invention relates to a steel slag grinding aid enhancer and a preparation method thereof. According to the technical scheme, the steel slag grinding aid enhancer is characterized by comprising thefollowing raw materials in parts by weight: 10-20 parts of a binary core component, 10-20 parts of triisopropanolamine, 5-10 parts of ethylene glycol, 10-25 parts of urea, 25-50 parts of deionized water and 1-3 parts of calcium hydroxide, wherein the binary core component is prepared from triethanolamine and glycerol in a ratio of (1-9): 3. The steel slag grinding aid enhancer can improve the grindability of steel slag, effectively improve the steel slag grinding efficiency, save energy and reduce consumption; therefore, the preparation method provided by the invention has the characteristicsof simple process and convenience in manufacturing.

Description

technical field [0001] The invention relates to a steel slag grinding aid enhancer and a preparation method thereof. Background technique [0002] At present, my country's iron and steel industry is developing at a high speed, and has become the world's largest steel production and consumption country, with steel output accounting for about 1 / 5 of the world's steel output. Like granulated blast furnace slag, steel slag is also a waste slag produced in the steelmaking process, and its emission is about 15%-20% of steel production. Statistics show that the steel slag accumulated in my country over the years has reached more than 300 million tons. If it is not treated and comprehensively utilized, steel slag will occupy more and more land, pollute the environment, cause waste of resources, and affect the sustainable development of the iron and steel industry. therefore. How to improve the utilization rate of steel slag has become a hot issue of common concern in the iron and...
