Abstract
The electric charcoal magnesia brick of organic bond is a kind of building by laying bricks or stones in the refractory materials of top-blown oxygen converter liner.
This refractory materials is developed for converter lining integrated masonry method.It is to be substrate material with magnesite clinker (MgO content is 85-92%), allocate electric calcined petroleum coke powdered carbon or electric calcined anthracite powdered carbon (calcining temperature 1470-1570 ℃, ashes＜6%) simultaneously into, and be that additive, resol (or asphalt modification resin) are that wedding agent is formed with graphite, be cured roasting behind mechanical pressing again, the fixing roasting temperature is 150-300 ℃.
These goods also can be used for building by laying bricks or stones the liner in steelmaking arc furnace, cupola furnace.
Description
The organic bond electric charcoal magnesia brick is a kind of building by laying bricks or stones in the refractory materials of top-blown oxygen converter liner.
At present, the top-blown oxygen converter liner adopts tar dolomite brick or stable konite brick (piece) to build by laying bricks or stones more both at home and abroad.Because lining life is not satisfactory, so begun to build by laying bricks or stones the gudgeon position or the whole liners except that fire door and furnace bottom position of converter lining in recent years both at home and abroad with magnesia carbon brick.Like this, though have certain techno-economic effect, but because magnesia carbon brick costs an arm and a leg, for reducing its consumption, just adopt the converter lining integrated masonry method, promptly converter lining is divided into working lining and permanent layer, build magnesia carbon brick by laying bricks or stones at working lining, and in permanent layer just by the converter shell position, what have uses the pitch magnesia brick, what have still uses the tar konite brick.Even so, but the life-span of the life-span of permanent layer and magnesia carbon brick still do not match, thereby limited the further raising of converter lining life.
When the technology of the present invention is intended to carry out the integrated masonry of top-blown oxygen converter liner, develop electric charcoal magnesia brick a kind of and novel product-organic bond that the magnesia carbon brick life-span is complementary.
The electric charcoal magnesia brick of organic bond is to be substrate material with magnesite clinker (MgO content is 85～92%), allocate electric calcined anthracite powdered carbon (1470～1570 ℃ of calcining temperatures simultaneously into, ashes＜6%) or electric calcined petroleum coke powdered carbon, and be additive with graphite, resol (or asphalt modification resin) is that wedding agent is formed.
The prescription of the electric charcoal magnesia brick of this organic bond (weight percent of composition) is: magnesite clinker is 68～88%, and granularity is pressed 0.5～15 millimeter of natural grading (wherein powder particles is 0.0074～0.088 millimeter, accounts for 10～15%); Electricity calcined petroleum coke powdered carbon or electric calcined anthracite powdered carbon are 8～20%, 0.074～0.088 millimeter of granularity; Resol (or asphalt modification resin) is 4～12%.
The electric charcoal magnesia brick of organic bond needs fixing roasting behind mechanical pressing, its fixing roasting temperature is 150～300 ℃.
The technical indicator of organic bond electric charcoal magnesia brick is as follows:
Cold crushing strength: 30～40MP
a
Volume density: 2.6～2.9g/cm
3
Folding strength: 7～9MP
a
Refractoriness under load:＞1560 ℃
Void content:＜12%
These goods also can be used for building by laying bricks or stones the liner in steelmaking arc furnace, cupola furnace etc.
Claims (3)
1, a kind of electrical carbon magnesia brick that is used to build by laying bricks or stones the organic bond of top-blown oxygen converter liner, it is characterized in that with magnesite clinker (MgO content is 85～92%) be substrate material, allocate electric calcined petroleum coke powdered carbon or electric calcined anthracite powdered carbon (1470～1570 ℃ of calcining temperatures, ashes＜6%) simultaneously into, and be additive with graphite, resol (or asphalt modification resin) is that wedding agent forms.
2, electric charcoal magnesia brick according to claim 1 is characterized in that the weight percent of its composition is: magnesite clinker is 68～88%, and granularity is by 0.5～15 millimeter of natural grading (wherein powder particles accounts for 10～15% for 0.0074～0.088 millimeter); Electricity calcined petroleum coke powdered carbon or electric calcined anthracite powdered carbon are 8～20%, 0.07～0.088 millimeter of granularity; Resol (or asphalt modification resin) is 4～12%.
3, electric charcoal magnesia brick according to claim 2 is characterized in that needing fixing roasting after the moulding, and its fixing roasting temperature is 150～300 ℃.
