Description
Technical field
The present invention relates to refractory materials, particularly relate to a kind of preparation method of water slag groove wear-resistant material.
Background technology
After blast furnace casting, containing many slags in molten iron, separated by a point slag runner, because the temperature of slag is very high, so rush with water, the temperature of slag is reduced, flow in pit.Sluice great majority adopted steel plate to lay in the past, and its abration position is more single, causes steel plate to occur hole, steel plate all will be changed during replacing,
Blast furnace bath slag runner is for blast-furnace slag being prepared into grain slag and grain slag being transported to the passage of grain slag treatment system.At present, bath slag runner liner mainly adopts cast iron plate or Cast Steel Plate, and cast iron plate or Cast Steel Plate be oxidized and erosion easily, and resistance to grain slag impacts and wears no resistance, and work-ing life was less than 1 year.In recent years, some inorganic high-abrasive materials are applied to bath slag runner, be better than cast iron plate and Cast Steel Plate, but in use also there is following shortcoming in the globality, solidity to corrosion, shock resistance etc. of structure:
(1) Applicable temperature is lower.The Applicable temperature of this kind of inorganic high-abrasive material is generally less than 500 DEG C, and blast-furnace slag temperature is generally at 1400 ~ 1500 DEG C, the grain slag temperature obtained after slag bath is also higher, the bath slag runner liner that inorganic high-abrasive material is formed stands the impact of high temperature grain slag for a long time, and this material easily produces and peels off and damage.
(2) heat-shock resistance is poor.Blast fumance is generally that two bath slag runners recycle slag, bath slag runner will stand the thermal shock jumpy of long-term temperature and impact, and the main material of current inorganic high-abrasive material is quartz sand and cement, and its thermal conductivity is low, high thermal resistance is poor, and the thermal impact of opposing temperature variation is poor.
(3) wear no resistance.This kind of inorganic high-abrasive material main material is quartz sand, and its Mohs' hardness is 7, and its wear resistance is good not enough, and the volume density of material monolithic is less, and void content is higher, wear resistance or poor.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of preparation method implementing water slag groove high-abrasive material easily, and the high-abrasive material Applicable temperature that the method is produced is high, good thermal shock, wear resistance are good, long service life.
To achieve these goals, present invention employs following technical scheme:
A production method for water slag groove wear-resistant material, the raw material of this wear-resistant material is composed as follows: Brown Alundum 50 ~ 70%; Silicon ash 3 ~ 6%, pure calcium aluminate cement 25 ~ 35%, additive 0.2 ~ 1% and toughener 1 ~ 3%, wherein in Brown Alundum, the particle of 5 ~ 3mm is 15-25%; The particle of 3 ~ 1mm is 20 ~ 30%; The particle of 1 ~ 0mm is 20 ~ 30%; Preparation method is as follows: material larger for particle in above-mentioned raw materials is carried out brokenly pulverization process in crusher, then size classification is carried out to the raw material of various component, again according to aforementioned proportion composition and ratio and grain size distribution, stir the process of equipment finally by overmulling, make the level material of each middle uniform particles distribution of each component.
Preferably, described toughener adopts steel fiber.Steel fiber can the toughness of strongthener, improves the folding strength of material, shock resistance and heat-shock resistance.
The mechanism of action of the present invention is: (1) corundum Mohs' hardness compared with high for >=9.0, fusing point 2250 DEG C, volume density be large, there is good antiacid alkali erosiveness, using it as main raw, the wear resistance of high-abrasive material can be improved, can amount of water be reduced simultaneously, improve intensity; (2) the refractoriness > 1600 ° of silicon ash, the use of silicon ash has the features such as high workability, low water storage, high-compactness and high strength.(3) pure calcium aluminate cement forms with the hydraulicity bonding agent of the content of aluminum oxide at about 70-80% through high temperature sintering with high-purity calcium oxide and aluminum oxide.Because this product alumina content is higher, various impurity component is relatively low.Particularly CA phase (monocalcium aluminate) and CA2(aluminic acid dicalcium) reasonably combined, make this product can not only give unshape refractory very high mechanical property, also make it have excellent high temperature performance, be very suitable for hot environment.The advantages such as have low impurity, bonding strength is high, and time of coagulation is stable.(4) steel fiber, can the toughness of strongthener, improves the folding strength of material, shock resistance and heat-shock resistance.
By the high-abrasive material that the inventive method is produced, adopt the high starting material of refractoriness to improve the use temperature of high-abrasive material, and wear resistance is good, good impact resistance.The main material itself introduced has higher hardness and wear resistance; Water slag groove high-abrasive material of the present invention also has good globality, higher volume density, higher intensity, increase the toughness of material simultaneously, prevent material cracks and the shock action slowing down grain slag, thus make this material have good wear resistance and shock resistance, finally improve the work-ing life of this material.Adopt can make the to destroy by rush of water repairing at position of the method for refractory material casting material easier in addition, and life cycle is longer.
