B) fuse assembling I: on fuse kludge, radiating tube and heat-radiation belt are superposeed successively, then load onto fuse backplate and for main leaf, be assembled into fuse assembly I;

C) dry weldering: the fuse assembling is put into and dried brazier baking weldering, and drying brazier temperature is 340 ± 20 ℃;

D) fuse assembling II: the fuse assembly I that two bakings are welded, by main leaf, is assembled into fuse assembly II;

E) main leaf is manual zinc-plated: flame welding is at the main leaf plated surface last layer tin of the fuse assembly II assembling by hand, and tin thickness is 2.5-3.0mm;

F) assembling hydroecium: by bolt, upper and lower to upper lower header and fuse main leaf is connected, should adds sealing gasket between hydroecium and main leaf when assembling, prevent from leaking;

G) dress side plate: left side plate and upper lower header and fuse are linked together with bolt;

H) pressure testing: heat radiator assembly is passed into the air pressurize 1min of 0.2-0.3Mpa, do not reveal;

I) dry: radiator is sent into drying oven and dry, bake out temperature 70-85 ℃, time 20-30min;

J) assembly assembling: by drawing other parts such as fan housing, protecting wire net are assemblied on radiator to composition heat radiator assembly;

K) spray paint: by drawing heat radiator assembly is sprayed paint;

L) dry: radiator is sent into drying oven by paint drying, 75 ℃ of bake out temperatures, time 15-20min;

M) dress annex: tank lid, water-level gauge, steam are drawn to flexible pipe etc. and install;

N) wooden-box package: heat radiator assembly adopts wooden-box package, and when vanning, the annex such as survey report, the quality certification is packed with case according to customer requirement.

Tool of the present invention has the following advantages: its technological process is simple, easy to operate, and the engineering radiator of production maximizes, and compact conformation, intensity are high, good stability, good airproof performance, are a kind of technological processes of high-quality production maximization engineering copper radiator.
