Abstract
A kind of method that rock wool is manufactured with yellow phosphorus furnace slag, is that bauxite is added in molten slag, kaolin ore and silica melt homogenizing in electric furnace, makes its acidity coefficient more than 1.7, then be centrifuged into cotton.
Description
Technical field
It is the technology category using waste residue rock wool the invention belongs to what inorganic silicate heat preserving and insulating material manufacture field.
Background material
The people for being engaged in heat preserving and insulating material know, the big what 1.7 of acidity coefficient is excellent mineral wool rock wool one by one, its production method both domestic and external be with coke in furnace cupola fused basalt, diabase and dolomite, slag, centrifugal drying silk forms cotton again, its heatproof, anti-moisture performance are significantly better than the mineral wool produced with blast furnace slag and coke in furnace cupola, but 1 ton of carbon dioxide will be discharged by often producing 1 ton of product, and the operation of furnace cupola in addition can also cause secondary pollution to surrounding enviroment.Requirement more and more higher with the whole world to reducing emission of carbon dioxide, furnace cupola technique is difficult to survive.It is in fact industrial to there are a large amount of molten slags to discharge daily, mostly it is to have stacked to cause disaster with water under high pressure granulation, majority fails fine utilization, such as its chemical composition element of yellow phosphorus furnace slag constitutes close with rock wool, as long as increase Al2O3And SiO2Content, you can the high-quality mineral wools of Mk >=1.7 rock wool one by one is made.
The content of the invention：
The present invention is to provide a kind of method of the hot direct manufacture rock wool of molten yellow phosphorus slag, it is when yellow phosphorus furnace slag is from production yellow phosphorus electric furnace lower dreg discharging mouthful discharge, with a certain amount of bauxite of addition, the mineral matter such as kaolin ore and Cab-O-sil, homogenizing electric furnace provided with corundum agitator and electrode material is co-flowed into one, form a uniform molten mass, four-roller centrifuge below subsequent melt inflow gets rid of silk into cotton, negative pressure sucks cotton collecting chamber, separation slag ball sprays into phenol resin solution simultaneously, certain thickness cotton plate is hot pressed on streamline or the products such as cotton shell and granulated wool are made.Compared with the current production classical way of rock wool both at home and abroad, this technique does not consume basalt and coke, carbon dioxide is not arranged thus, without the furnace cupola of surrounding enviroment secondary pollution can be caused, rock wool product more higher-quality than soaring oven process can be produced, the green production boundary turned waste into wealth is reached, and has larger economic benefit.
Brief description of the drawings
Fig. 1 is present invention process schematic flow sheet
Yellow phosphorus furnace slag flows out from phosphorus production electric furnace bottom cinder notch, a certain amount of bauxite powder is added above stream stock, the inorganic mineral such as kaolin miberal powder and Cab-O-sil, it is co-flowed into homogenizing electric furnace, stirred by corundum agitator, raw material are melted with the electric rubbish of graphite, four-roller centrifuge below being flowed into after heat homogenizing gets rid of silk into cotton, negative pressure sucks cotton collecting chamber, by lower section, discharge slag ball sprays into resin sol solution simultaneously, enter article manufacturing equipment with conveyer belt, hot pressing is into products such as rock cotton board, cotton shell and granulated wools.
Embodiment
Certain domestic Yellow Phosphorous Plant furnace power is 1500kvA, molten slag composition is shown in Table 1, slag notch draws molten slag below from phosphorus production electric furnace, the proportioning determined above it by cold conditions formula test, it is uniformly added into kaolin and Cab-O-sil, compound flows into a rectangle homogenizing electric furnace, the electric rubbish three of a diameter of 250 millimeters of graphite is respectively installed at import and exit in stove, material temperature is in 1400-1450 degree Celsius in adjustable transformer control stove, the continuous underthrust supplement of consumption of electrode, corundum agitator is installed in electric furnace center, raw material are made to use up block fusing homogenizing, four-roller centrifuge below the melt inflow of homogenizing gets rid of silk into cotton, cotton collecting chamber is sucked by negative pressure, slag ball lands, phenol resin solution is sprayed simultaneously, the cotton slope of 40 millimeters thicks is hot pressed on streamline.

Claims (3)
1. with molten slag addition bauxite, kaolin ore and silica in phosphorus production, the method for being homogenized through heat fusing and rock wool being made.
2. the method described according to claim 1, bauxite, kaolin ore and silica of the addition rich in alchlor and silica directly in molten state yellow phosphorus furnace slag, melting homogenizing, make its acidity coefficient reach more than 1.7 as classical rock wool production product.
3. the method described according to claim 2, homogenizing electric furnace is using graphite rod for heating electrode, and corundum agitator stirring molten mass, material temperature is controlled in 1400-1500 degree Celsius into cotton.
