Abstract

The invention discloses an application method for adding an anti-corrosion and thermal-insulation material into the shell of a cement rotary kiln. The application method is characterized by comprising the following steps that 1), positions are determined; 2), construction is performed; 3), bricks are laid; 4), marks are made on the outer part of a barrel body; 5) temperature is measured; 6), a thickness condition is detected; and 7), a test result is evaluated and analyzed according to records and pictures. The application method has the beneficial effects that a high-temperature-resistant and thermal-insulation coating can resist temperature of 600 DEG C; a thermal insulation rate is high; the heat conductivity coefficient of the coating is only 0.06W/m.K, so that radiation heat of infrared rays and heat conduction can be effectively inhibited; thermal insulation inhibition efficiency can reach about 80%; thermal radiation and heat conduction loss of a high-temperature object can be inhibited; the material can be retreated after insulation, pressure-proof treatment and solidification, so that irregular objects can be conveniently coated; and the coating can be smeared on a kiln body for 3 mm.

Description

The application process of anti-corrosion, heat-barrier material is added in cement rotary kiln to housing

Technical field

The present invention relates to a kind of cement rotary kiln body design field, more particularly, to adding to housing in cement rotary kiln The application process of anti-corrosion, heat-barrier material.

Background technology

At present kiln cylinder body surface temperature is higher, and radiation loss is larger, accounts for kiln system half；There is cylinder in 80% rotary kiln Body etching problem, has a strong impact on refractory brick and uses and cylinder service life；Good solution is not found at present both at home and abroad.

The content of the invention

It is an object of the invention to provide it is a kind of, solve to reduce kiln cylinder body temperature, extend kiln cylinder body service life, prevent safety There is and reduce the problem of production cost in accident.

The technical solution adopted for the present invention to solve the technical problems is：

The application process of anti-corrosion, heat-barrier material is added in a kind of cement rotary kiln to housing, it is characterised in that including following step Suddenly：

1）, position determine：Testing site is determined with manhole door, other two points is released respectively by 120 degree along certain point position ring, often The individual 1.5*2.5m that presses is drawn on inwall cylinder；And picture and record；Cylinder inboard wall test point must be on same ring；

2）, construction：Testing site is placed on 6 before brushing anti-corrosion, heat resistant material:00 position, and clean up, with brush point 2-3 Uniform, the thickness about 1.5mm all over carefully brushing, and picture and record；Other two points are carried out by the above process；

3）, lay bricks：Three spot printings will can lay bricks after brushing after 24h, put down gently when laying bricks, and lacquer painting must not be caused to have cut； Test position is drawn on brick face after brick getting well, and has taken picture and record；

4）, after corresponding three points in cylinder outside carry out, the 4 fillet welding cap nuts put at each respectively are to identify；And retention of taking pictures And record；

5）During firing up slow-speed, thermometric is carried out along the same ring of three points with temperature-measuring gun, measured respectively 1. 2. 3. 4. 5. 6. the temperature of six points, surveys three times every time, and makes a record, and surveys one time per 2h during intensification；Survey one in the morning during normal operation Secondary, survey once in the afternoon, tie-in three days；Can be helped survey weekly once until the lower cycle changes brick by owner in time later；

6）, the lower cycle 3 points of refractory brick and the depth information of dope layer are checked when changing brick, and take pictures retention and record；

7）, by record and photo test effect is evaluated and is analyzed, draft test report.

Beneficial effects of the present invention：Thermostable heat-isolating coating, 600 DEG C of heatproof, heat-insulation and heat-preservation rate is splendid, coating heat conductivity All there was only 0.06W/m.K, can effectively suppress and shield ultrared radiant heat and the conduction of the heat heat-insulation and heat-preservation suppression efficiency Up to 80% or so, the heat radiation of high temp objects and the conduction of heat can be suppressed to scatter and disappear, can be reprocessed after insulation, pressure, solidification, Brushing irregularly shaped object is convenient, and coating is directly brushed 3 millimeters on kiln cylinder body.
