Embodiment Construction

[0023] The materials used in the technical solution will be described in detail below with reference to examples.

[0024] Silica is silicon dioxide, also known as quartz sand. It is used in the chemical industry to prepare silicon compounds and silicates. It can also be used as a filler for sulfuric acid towers. It can also be used in glass, ceramics, Portland cement, etc. in the building materials industry. It is used as raw material for smelting ferroalloys such as industrial silicon. Its chemical properties are very stable, insoluble in water and does not react with water. It does not react with common acids. At high temperature, silicon dioxide eutectically melts with alkaline oxides or certain metal carbonates to form silicates.

[0025] Alumina is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionic crystal that can be ionized at high temperatures and is often used in the manufacture of refractory materials. There are di...

Abstract

The invention discloses a method for preparing artificial vesuvianite from liquid refined manganese slag and belongs to the field of metallurgy. Two times of refining are implemented. The method comprises the following steps: refining manganese slag twice, adding a corresponding tempering material, further pouring slag slurry after two times of refining into an artificial vesuvianite shaking furnace, adding a silicon resin polyether emulsion as a foam stabilizer, performing smelting, casting the slag slurry mixed liquid into a molding mold, putting a molded sample and the mold into a shuttle kiln, and performing annealing, cooling, demolding and cutting, so as to obtain the artificial vesuvianite. The method for preparing the artificial vesuvianite from the liquid refined manganese slag, which is disclosed by the invention, aims to widen the utilization range of the manganese slag, increase the additional value of the manganese slag and increase economic benefits.

Description

technical field [0001] The invention relates to a method for preparing artificial volcanic rock, in particular to a method for preparing artificial volcanic rock by using liquid refined manganese slag, and belongs to the field of metallurgy. Background technique [0002] At present, manganese alloys such as silicon-manganese alloys, high-carbon ferromanganese and medium-carbon ferromanganese are usually indispensable deoxidizers and manganese alloys for the production of ordinary steel. Low-carbon ferromanganese, electric furnace metal manganese and electrolytic manganese are alloying agents for producing high-quality steel. Accompanied by the rapid growth of the output of special steel including stainless steel, high-quality manganese alloys have been widely used, and its output has grown rapidly. [0003] Manganese slag will be produced during the production process of manganese alloy, and the waste slag contains more or less a certain amount of silicon-manganese alloy pa...
