Abstract

The invention discloses a method for preparing a refractory plastic by using titanium-containing blast furnace slag, and belongs to the field of waste reuse. The method for preparing the refractory plastic by using titanium-containing blast furnace slag comprises the following steps: immersing blast furnace slag in hydrochloric acid, carrying out preliminary treatment on the blast furnace slag by using a sodium hydroxide solution, carrying out advanced modification on the titanium-containing blast furnace slag at a high temperature by using sodium nitrate, potassium permanganate and isopropyl tri(dioctylpyrophosphate) titanate, and mixing the obtained substance with kyanite, calcium aluminate cement and a dispersant to obtain the refractory plastic. Instances prove that the bulk density (1000DEG C * 3h) of the refractory plastic is not lower than 3.2g / cm<3>, the compressive strength (1000DEG C * 3h) is not smaller than 142MPa, the wear resistance (1000DEG C * 3h) is not smaller than 4cm<3>, the plasticity index is 25-35%, and the refractoriness is not lower than 1800DEG C.

Description

technical field [0001] The invention discloses a method for preparing refractory plastics by using titanium-containing blast furnace slag, which belongs to the field of waste recycling. Background technique [0002] Blast furnace slag is the waste slag produced when smelting pig iron. When smelting pig iron, the raw materials of the blast furnace are added. In addition to iron ore and fuel (coke), a considerable amount of limestone and dolomite need to be added as flux. When the furnace temperature reaches 1400-1600°C, the flux reacts with the iron ore at high temperature to form pig iron and blast furnace slag. Blast furnace slag is a fusible substance consisting of gangue, ash, flux and other impurities that cannot enter pig iron. The discharge of blast furnace slag per 1 ton of pig iron varies with the ore grade and smelting method. 0.3-1.2t of blast furnace slag is produced per ton of pig iron. [0003] With the rapid development of iron and steel enterprises, a large...
