The thickness of mounting hole clearance distance, refractory brick, designs the appearance and size of kilneye prefabricated component, and makes shaping grinding apparatus；
B) prefabricated component makes：Fixed iron plate is placed in shaping grinding apparatus, anchoring piece and installation bolt is welded, is pressed using castable
Cast being carried out according to the proportioning that adds water to vibrate shaping, being put into after shaping in the room of constant temperature and humidity and conserved, high temperature kiln is put into after the demoulding
Inside further it is sintered drying；
C) kiln mouth structure cleaning and inspection：Kilneye to needing to change is cleaned out, ensures that kilneye cylinder, without deformation, is hampered without installing
Hinder thing；
D) kilneye prefabricated component is installed：By fork truck, chain block instrument, installed, method is identical with kilneye cap iron installation,
Refractory fiber cotton is placed in prefabricated component and kilneye brick junction, prefabricated component and prefabricated component junction；
E) inspect for acceptance；All prefabricated components are installed after terminating, and are inspected for acceptance, and just be can be used after passed examination.
Beneficial effects of the present invention：
（1）Economic benefit：By taking 5000t/d rotary kilns as an example, kilneye can only use 8 according to traditional castable construction method
Month, kilneye is built by laying bricks or stones using this engineering method and be can be used 36 months, in 3 years, a kiln can save 3 maintenances, each kilneye maintenance cast
Material cost and construction cost can directly save 300,000 yuan of expense according to 100,000 yuan/time.
（2）Social benefit：Kilneye is built by laying bricks or stones using this engineering method, the kilneye life-span greatly increases, reduce kilneye maintenance frequency, drop
The consumption of low castable, is that country has saved the substantial amounts of all kinds of energy and productivity, is that motherland's environmental protection, energy-conservation cause make huge tribute
Offer.The engineering method construction system is simple, it is to avoid kilneye castable abolishes work, has saved substantial amounts of manpower, shortens the duration, drops
Low cost.
The construction method engineering method has filled up domestic rotary cement kiln eye prefabricated component job specfication.
