Problems solved by technology

There are some defects in the formula composition of the liquid grinding aids studied and used at home and abroad at present: due to the increasing shortage of world oil resources, the prices of the main raw materials triethanolamine and organic silicon polymers of the grinding aids are also constantly rising. The price is expensive, the source is short, the dosage is too large, and the effect on the slag grinding aid is not obvious, and the performance of the slag is not improved or the improvement effect is not large. Seeking a relatively low-cost and effective slag grinding aid product is a domestic grinding aid. The industry urgently needs to solve the problem, and the slag powder production enterprises require that the output of the mill should be increased by more than 14%, in order to further reduce power consumption and save energy

Abstract

The invention discloses a special composite liquid grinding aid for blast furnace slag. The special composite liquid grinding aid comprises components in parts by weight as follows: 1-10 parts of triisopropanolamine, 1-10 parts of triethanolamine, 10-20 parts of mixed alcohol, 1-10 parts of magnesium aluminum silicate, 1-10 parts of ethyl acetate, 5-20 parts of sugarcane molasses, 1-10 parts of sodium carbonate and the like. A preparation method of the special composite liquid grinding aid for the blast furnace slag comprises steps as follows: A, in terms of parts by weight, water is injected into a reactor and heated, then sodium hexametaphosphate, anhydrous sodium metasilicate and sodium acetate are added, and a solution I is obtained; B, sodium carbonate and magnesium aluminum silicate are added to the solution I, and a solution II is obtained; C, triisopropanolamine, triethanolamine, mixed alohol, ethyl acetate and the sugarcane molasses are added to the solution II and stirred, then sugarcane molasses alcohol liquid waste and a polycarboxylate superplasticizer are added, a mixed solution is stirred again and sieved, and a filtrate obtained after filtering is taken as the special composite liquid grinding aid for the blast furnace slag. The grinding aid can reduce the powder surface free energy, can be universally applicable, adopts a simple and understandable preparation technology and has great popularization value.

Description

technical field [0001] The invention relates to a slag grinding aid in the field of blast furnace slag fine powder manufacturing, in particular to a special composite liquid grinding aid for blast furnace slag and a preparation method thereof. Background technique [0002] At present, my country's iron and steel output is about 350 million tons. Based on the domestic average production of 1 ton of pig iron produces 0.50 tons of slag, my country's slag output is about 175 million tons. Therefore, how to utilize slag solid waste is a topic that Chinese metallurgists have been studying for many years, and it is also a practical problem that should be solved emphatically in developing a circular economy and building a conservation-minded and environment-friendly society. For a long time, most of the slag has been used as cement admixture, and it is ground together with cement clinker. The fineness of slag is generally 250m in terms of specific surface area 2 / kg, this has not b...
