Description
Technical field
The invention belongs to intermediate frequency furnace ramming mass technical fields.Intermediate frequency furnace is smelted more particularly to a kind of iron based on aluminium chromium slag
With ramming mass and preparation method thereof.
Background technology
Aluminium chromium slag is by-product derived from the alloys such as thermite reaction metal smelting chromium, ferrochrome.In metal smelting chromium
Shi Liyong metallic aluminiums and the Cr in chrome ore2O3Reduction reaction occurs and produces crome metal, metallic aluminium powder and Cr2O3In the state of melting
It is lower that fierce chemical reaction, the Al of generation occurs2O3Rapidly to corundum phase transition, at the same with the complete Cr of unreacted2O3Solid solution,
Generate aluminium chromium solid solution, i.e. aluminium chromium slag.According to statistics, China will generate 50~600,000 tons of aluminium chromium slag every year, contain in aluminium chromium slag
The Cr of about 0.08~0.11mg/g6+(Chinese chromium residue Cr6+Control standard is 0.008mg/g), it has been included into《Country's danger
Dangerous waste register (2016) code：315-003-21》.Currently, aluminium chromium slag is generally taken as industrial refuse to handle, it is piled into evil,
Huge environment and financial burden are brought to society and enterprise, therefore innoxious application is carried out to aluminium chromium slag and is of great significance.
Intermediate frequency furnace lining is the key position of intermediate frequency furnace, and the quality of fire proof material of furnace lining is to determine intermediate frequency furnace li`, casting
One key factor of quality and security reliability.Intermediate frequency furnace has many advantages in terms of smelting, but lining thickness it is relatively thin,

Intermediate frequency furnace is made of with corundum, alumina, mullite etc. for primary raw material with neutral dry type ramming material, especially big
First choice furnace lining material is corundum-spinel ramming mass when type steel-making of intermediate frequency furnace.The reason is that：It is added in alumina ramming mass suitable
The magnesia (or synthetic spinel) of amount and suitable agglutinant, corundum is reacted with magnesia at high temperature generates spinelle, generates one
Fixed volume expansion can effectively inhibit the cracking of furnace lining working lining, reduce the micro-crack of working lining, extending furnace lining life.But
It is that material purity in recent years due to these high-quality is lower and lower, and reserves are limited, lead to increasing price of raw materials, for giving birth to
It is higher to produce intermediate frequency furnace lining cost.
" a kind of metallurgy electromagnetic induction intermediate frequency furnace ramming mass " (CN103058669A) patented technology, using alumine, magnesium
Sand, spinelle and SiO 2 superfine powder etc. prepare intermediate frequency furnace ramming mass as raw material, although the compactness and anti-slag of material are invaded
Lose excellent, but the raw materials such as magnesia and spinelle are difficult to obtain and higher price；In addition in material shared by compact high-alumina alumina aggregate
Ratio it is higher, improve the thermal coefficient of material.
