Abstract
The present invention discloses a dinas-carbofrax brick used as a refractory material. The dinas-carbofrax brick uses dinas granules and dinas powder as main components and uses silicon carbide as an auxiliary component; in addition, a mineralizer and a binder are added to the components to be made into the dinas-carbofrax brick; the components comprise 55 to 85 wt% of dinas, 15 to 45 wt% of silicon carbide, 1 to 2 wt% of carburetant, 9 wt% of binder. Raw materials are proportionally matched, mixed, shaped, dried, sintered, checked, selected and made into finished products. The present invention has the advantages of high thermal shock stability, high softening point under a load, high qualifying rate of the finished products, long service life, simple manufacturing technology, etc.; the long service life of the dinas-carbofrax brick is 5 to 10 times longer than that of a common brick, and the dinas-carbofrax brick is suitable for industrial production.
Description
The present invention relates to a kind of Dinas-carbofrax brick, belong to refractory materials.
Along with the development of ceramic fire resistant industry, for supporting and protecting the kiln furniture material of goods that new requirement is provided.Present most of producer still uses traditional clay matter and siliceous refractory [material to do kiln furniture material.Because of lower, the yielding silica brick of clay brick load softening point has the shortcoming of resistance to thermal shocks difference again, often make the kiln furniture material breakage too high.Be used for the steel industry tunnel furnace and use the general silica brick shelf of GZ-93 brick, use temperature is between 1450-1500 ℃, and sometimes up to more than 1600 ℃, because of the cooling system relation, general silica brick has fracture more in process of cooling.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art provides a kind of thermal shock resistance strong, and manufacture technology is simple, is raw material, is equipped with the Dinas-carbofrax brick of wedding agent, mineralizer with silica, silicon carbide.Do not see the reported in literature identical by retrieval with the present invention.
The object of the present invention is achieved like this.It is to be major ingredient with silica granule and ground silica, and silicon carbide is auxiliary composition, adds mineralizer, wedding agent is made, its proportioning (weight %) is silica 55-85, silicon carbide is 15-45, adds wedding agent 9, mineralizer 1-2, and the powdery silica accounts for 30% of raw material weight.
Purpose of the present invention can also reach by following measure: described wedding agent is milk of lime, spent pulping liquor, and wherein milk of lime is 8% of raw material total amount, and spent pulping liquor is 1%, and mineralizer is an iron scale.In order to realize goal of the invention, the weight percent content of above-mentioned raw materials can be silica 70, silicon carbide 30, adds the milk of lime that accounts for raw material total amount 8%, 1% iron scale, 15 spent pulping liquor.After by formulation content raw material being mixed, the water content of moulding is 4-6.5%.Its production method is: raw material is cooperated according to the above ratio mix, moulding, drying, burn till.
The present invention has following advantage compared to existing technology:
1, thermal shock resistance is strong, and 1100 ℃/water-cooled of thermal shock resistance number of times reaches 13 times.
2, load softening point height.Greater than 1650 ℃.
3, breakage rate is low.Through use turnover 3 times in tunnel furnace, breakage rate is 2.15%.
4, long service life.Than the high 5-10 of general silica brick doubly.
5, manufacture craft is simple, is fit to suitability for industrialized production.
Below in conjunction with embodiment in detail the present invention is described in detail.
The present invention is major ingredient with the silica, and silicon carbide is for auxiliary, adds milk of lime, iron scale, spent pulping liquor and makes.Its proportioning raw materials is (100kg is an example with preparation)
| Silica granule | Ground silica | Silicon carbide | Milk of lime | Iron scale | Spent pulping liquor | |
| Example 1 | 40 | 30 | 30 | 8 | 1 | 1 |
| Example 2 | 45 | 30 | 25 | 8 | 1 | 1 |
| Example 3 | 50 | 30 | 20 | 8 | 1 | 1 |
| Example 4 | 55 | 30 | 15 | 8 | 1 | 1 |
| Example 5 | 25 | 30 | 45 | 8 | 1 | 1 |
Make finished bricks after cooperating the shaping and drying that mixes to go into klining tying-in pick according to the above ratio the raw material.Silica of the present invention can replace with useless silica brick.
Mixing with sand mill in concrete ratio batching of the present invention back, sends into the moulding of 260T rubbing machine after mixing, and moulding moisture content is the 4-6% of raw material weight, and the present invention is 6%.Send into ground a heatable brick bed drying after the moulding, go into down-draft kiln after the drying and burn till, its firing temperature is 1420-1470 ℃, and the best is 1460 ℃, and firing period is about 400 hours.
Size of the present invention, model, specification can design according to the production needs, and firing period is grasped about 400 hours flexibly according to goods.
Specific performance parameter of the present invention is:
Compressive strength: 67.69MPa
Apparent porosity: 20%
Volume density g/cm
3: 1.95
1100 ℃ of water-cooleds of thermal shock resistance are inferior: 13
0.2MPa ℃ of loading softening starting point:＞1650
