As machine of domestic chain comb with a double-edged fine-toothed comb - the rapid development of round craft of rotary kiln ball, cold machine of machine of catenary comb with a double-edged fine-toothed comb, rotary kiln, annulus of 3 old lead plane run the exercise efficiency that matters to whole product line normally, the factor that can affect 3 old lead plane to run normally has a lot of, among them of fireproof material reasonable use in attaching most importance to heavy. As a result of machine of catenary comb with a double-edged fine-toothed comb - the equipment of rotary kiln is much, difference of working procedure operating mode is bigger, the fireproof material liner of different position needs to bear of different stock erode, chemistry is eroded, urgent cold urgent hot action, and the structure is complex, construction and roast difficulty, what choose reasonable fireproof material and scientific build by laying bricks or stones to build a method to be able to maintain 3 old lead plane not only from this is normal move, and still can rise energy-saving fall the action of bad news, reduce the moving cost of manufacturer home thereby.
The fireproof material that next each working procedure introduce respectively below chooses a requirement:
One, machine of catenary comb with a double-edged fine-toothed comb
Graph sketch map of machine of 1 catenary comb with a double-edged fine-toothed comb
1, microtherm area
Because the dirt in microtherm area air current is less, take no account of tatty problem commonly when choosing fireproof material, reason uses light simple stuff to regard the job as the layer only, between side wall armor plate and light simple stuff again cotton of a heat preservation prevents laid to string together wind and burn out armor plate.
2, high temperature area
High temperature paragraph because need consideration is fireproof and the element such as wear-resisting is used pledge again pouring makings add pledge gently pouring the complex structure that makings photograph integrates, roof of machine of catenary comb with a double-edged fine-toothed comb and high temperature paragraph side wall uses anchorage solid brick commonly union is pouring the form of makings, but in high temperature paragraph laid needs on way of side wall standard a splint, the profit that such doing is to install to expand artificially seam, can the destruction that because expand to arise to anchorage solid brick,older rate land eliminates action.
2, rotary kiln
Graph sketch map of 2 rotary kiln
Rotary kiln is ball group the very important segment in producing a course, the product line that the fireproof material stand or fall of rotary kiln decided whole ball is round directly whether normal movement. Traditional rotary kiln is fireproof because material waits for an advantage considering the high temperature resistant, wearability of fireproof material, choose the fireproof material that pledges again commonly, but the coefficient of thermal conductivity of this kind of fireproof material is big, derive through fireproof material the quantity of heat that go is big also, create the waste of the sources of energy.
To solve this problem, my company uses prefab brick belt and pouring makings belt is removed the configuration that decorate, and be between fireproof material and skin of rotary kiln kiln laid pledges gently heat preservation cotton, it is OK avoid caloric loss effectively, can reduce what the rotational weight of rotary kiln reduces electric energy thereby to use up on the other hand. But need to consider what operating mode condition falls to expand in fireproof data design and construction process trend, working layer surface is stood by to increase in prefab brick expand board reach irrigate casting setting to expand seam, expand seamed span setting need is decided according to operating mode temperature, and these expanding seam cannot be well versed in.
3, annulus cold machine

Annulus cold machine is to use air cooling to cool the equipment of pellet, the fireproof material of liner makes by two parts:
1, the stage car column of annulus cold machine board
Column of car of stage of annulus cold machine board brick is to have two kinds of ways at present: One kind is make it is small cent for fluctuation two parts, the advantage is installation, change convenient, defect is air leak serious; Another kind is make it chunk divides annulus of inside and outside into a few chunk neck and neck do not divide, the advantage is loss of material rigor, quantity of heat small, defect is it is installation, difficult to change, can when unite when overhaul change. Two kinds of forms need a basis to client equipment maintains means and cycle and be decided.
2, the cover on annulus cold machine
The cover on annulus cold machine uses anchorage solid brick commonly union is pouring the configuration design of makings, pouring makings criterion is used like be similar to machine of catenary comb with a double-edged fine-toothed comb pledge again pouring makings add pledge gently pouring the complex structure that makings photograph integrates, pledge through changing the capable person of working layer and outer heat-insulation layer ply will handle different cold paragraph.
