Technical field
The present invention relates to smelted furnace cinder reutilization technology field, more particularly to a kind of smelted furnace cinder is reused in stove block
The method built.
Background technology
Blast furnace is a closed successional counter-current reactor, and furnace charge fills whole blast furnace space, forms stock column, furnace charge
Predicted and on high-temperature coal air-flow act on, be constantly heated, decompose, reduction, softening, melting, drippage, ultimately form slag
Iron melt body and separate.Molten iron and clinker are the final products of blast furnace process.Clinker by the gangue raw material and coke ash of furnace charge with
And assistant reducing agent is formed.The main chemical compositions of clinker are substantially：Silica 4~30%, aluminum oxide accounts for 5~10%, oxygen
Change calcium account for 26~44%, magnesia accounts for 8~36%, and iron oxide accounts for 3~12% etc., wherein also containing some sulphur, titanium, potassium,
The elements such as sodium.Clinker is a kind of byproduct that blast furnace ironmaking is produced, by working process, is mainly used in making construction material, stove
Temperature when slag comes out from blast furnace is generally 1450-1550 DEG C.Due to clinker by high temperature sintering as a kind of resistance to well
High-temperature material, the raw material that can be used as building by laying bricks or stones stove is used.
The content of the invention
The purpose of the present invention is that to provide a kind of smelted furnace cinder to solve the above problems and be reused in stove and built by laying bricks or stones
Method.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of smelted furnace cinder is reused in the method that stove is built by laying bricks or stones, and specific operating method includes following steps：
（1）Cooling：The clinker of blast furnace output is subjected to natural cooling, the final temperature after cooling is less than 30 DEG C；
（2）Grinding：Clinker after cooling is crushed using grinder；
（3）Screening：Using multilevel screening machine by step（2）Clinker afterwards is screened, and separates fine slag, the 5-50 purposes of -50 mesh
Thick slag and 5 three kinds of mesh above large granule slags, 5 mesh above large granule slag return to step（2）Crush again or landfill disposal；
（4）Mixing：By step（3）The fine slag of middle generation and thick slag and clay, refractory material, wood-fibred particle, waterglass, sulfurous
Simultaneously water filling stirs for sour sodium mixing；The weight proportion of the mixing is：Fine slag 38-42；Thick slag 7-12；Clay 12-18；Fire resisting
Material 10-15；Wood-fibred particle 1-3；Waterglass 3-6；Sodium sulfite 0.5-1；Water 12-18；
（5）Extrusion forming：Adobe is made in raw material pressurization after mixing is mixed thoroughly；
（6）Sintering：By step（5）The adobe of middle production, is sintered at a temperature of 800 DEG C -1000 DEG C, is incubated 5~6 hours, system
Into refractory brick；
（7）Cooling and storage：Refractory brick after sintering is cooled down, check sum code pile is deposited；
（8）Build by laying bricks or stones：Cementing materials, which are mixed, with refractory brick and flame-retardant fibre board carries out building by laying bricks or stones for stove；Described cementing material
Material is formed by weight proportion 40-50 cement, 22-28 bauxites aggregates, 14-16 water, 8-10 phosphoric acid, the stirring of 2-7 sodium hydroxides dry powder；
（9）Examination is burnt, checked and accepted：After building by laying bricks or stones stove solidification after, in stove place furnace charge carry out examination burning, detection stove inside and outside whether
There is crack.
Described bauxites aggregate is alumina aggregate, is also refractory aggregate.
According to the present invention, when being pressed into adobe, useless blast furnace slag and stick that steel and iron industry feels a delicacy about make use of
Soil, refractory material, wood-fibred particle, waterglass, sodium sulfite mixing；Blast furnace slag is largely produce in metallurgical industry discarded
Thing, severe contamination is will also result in environment, and blast furnace slag is pressed into brick, realizes the utilization to pollutant, again by the present invention
Realization is turned waste into wealth, the effect of the treatment of wastes with processes of wastes against one another.Greatly reduce the usage amount of soil resource.
The beneficial effects of the present invention are：Clinker can be recycled, improve the utilization rate of clinker, and built by laying bricks or stones
Stove out is heat-resist, reduces the consumption of other raw materials, economic and environment-friendly.
