The invention relates to a method for installing and fixing a large lining plate for a metallurgical steel slag treatment hot stuffy tank. The method is characterized in that: plate blanks serving as lining plates lean against an embedded iron plate on the wall of the hot stuffy tank in certain angles and play a role in structure stabilization by using dead weight, and certain gaps are reserved on the plate blanks and the cement tank wall to form a heat insulation layer so as to play a role in protecting the tank wall. At the lower ends of the plate blanks, stop iron and wedge iron are welded close to two sides of the plate blanks by using tank bottom steel plates to form inner wedge and outer stop; and the degree of freedom of the plate blanks is controlled, and the extension of the plate blanks is not affected, so that the stress of the plate blanks is fully released and the influence of expansion with heat and contraction with cold on the lining plate is eliminated. The plate blanks are connected by hooks and iron bars to form a whole. A door shape is welded on an embedded steel plate on the upper part so as to reinforce the upper parts of the plate blanks. The method stabilizes the structure of the lining plate, enables the lining plate to resist impact, reduces the damage rate of the lining plate, prolongs the service life of the lining plate, is convenient for construction, and can save a large amount of fund.

According to the anti-corrosion coating, the heat exchanger applying the anti-corrosion coating and the coating method, the surface of the heat exchanger is coated with the nanometer hydrophobic coating, organic-inorganic hybrid organic silicon serves as a main component, the main chain of the organic-inorganic hybrid organic silicon is an inorganic Si-O-Si chain segment, the anti-corrosion performance is better than that of organic silicon, Si-OH and the surface of a metal base material can easily form a Si-O-Me bond, and therefore the anti-corrosion performance of the heat exchanger is improved. Therefore, the adhesive force between the coating and the metal base material can be enhanced; the branched chain is a hydrophobic organic chain segment, so that the hydrophobic organic chain segment has good hydrophobicity.
