Description
Technical field
The present invention relates to a kind of hot-dip aluminizing silicon zinc steel plate processing technology。
Background technology
In recent years, due to greatly developing of the basic industries such as electric power, traffic, communication, building, the demand of galvanized steel is increased day by day。The ground structure galvanizing steel enterprise such as current Guangdong, Zhejiang, Shandong, Jiangsu, Hebei, northeast takes advantage of a turn of events and get on, and current structural steel galvanized pot has kept the large-scale development, and holding zinc amounts from original tens tons increases to 700～800 tons and hold zinc amounts。Annual production reaches the enterprise of ten thousand tons and has many families。The structural members such as 3～620 main plating pieces are freeway guardrail, power transmission and transformation, communication steel tower, street lamp post, lightgage steel joist for building。Tenth Five-Year Plan Period, China will accelerate Transportation Infrastructure Construction, the weight electricity of highway construction is that two vertical two horizontal Important Sections are built up in the whole nation, " five vertical 73 is horizontal " trunk lines of national expressways ten thousand kilometers, to year, whole nation highway 2.62005 total kilometrage reaches ten thousand kilometers, and highway is more than ten thousand kilometers, and more than 1602.5 2 grades highways reach ten thousand kilometers。Starting to accelerate region 282002 highway network improvement year, western inter-province highway total scale ten thousand kilometers, current 1.5 are building ten thousand kilometers, need to go into operation ten thousand kilometers, to build up trunk lines of national expressways ten thousand kilometers from year 0.512001～2010 west area；Except, except building 1.26, also going into operation。Between year, the highway that annual 3900km2000～2010 will be built, need to increasing the zinc-plated guardrail board of 1200～1500km6～ten thousand ton every year newly, ten thousand tons of coating steel pipes and 7.52.4～30.8 ten thousand ton galvanized parts, the annual communication～1.0 steel tower galvanized steel for electric power power transmission and transformation is up to ten thousand tons。Estimate that year structure 40～502001 galvanizing steel amount is more than ten thousand tons, year ten thousand tons of zinc of consumption, it is contemplated that to structural steel in 15013 zinc-plated should close to ten thousand tons, year 10000 tons of zinc of consumption。
Our times environment goes from bad to worse, acid-base value in natural climate differs, acid rain is there is particularly in serious pollution area, acid rain is bigger to the corrosion strength of steel construction facility, substantially reduce the service life of steel construction facility, therefore, just now zinc-plated have comparatively great meaning, traditional just now zinc-plated plating is pure zinc, its resistance to corrosion is more weak, coating adds aluminum and silicon, the resistance to corrosion of coating can be greatly enhanced, the method coating out-of-flatness of traditional silicon zinc of aluminizing, hot dip effect is bad, coating is made to there is leak, affect steel service life, therefore the technology of a kind of improvement it is badly in need of to solve above-mentioned technological deficiency。
Summary of the invention
The invention provides a kind of hot-dip aluminizing silicon zinc steel plate processing technology。
The technical scheme that the present invention is directed to above-mentioned technological deficiency proposed is:
A kind of hot-dip aluminizing silicon zinc steel plate processing technology, its manufacturing process is:
(1) by polishing steel plate rust cleaning and the burr on surface of going out；
(2) steel plate is carried out blasting treatment；
(3) the steel plate water under high pressure handled well in step (2) is carried out hydro-peening, place into and electrolytic cleaning machine carries out electrolytic cleaned；
(4) preheating steel plate, heats plating solution simultaneously；
(5) being put into by the steel plate of preheating in the plating solution of heating, plating solution is stirred simultaneously, whipping process continues 20-30 minute；
(6) steel plate taken out and cool down rapidly, preparing hot-dip aluminizing silicon zinc steel plate。
In described plating solution, a Parts by Ingredients is Si:3-6 part, Al:55-60 part, Zn:38-45 part。
Steel plate preheating temperature is 560-580 DEG C, and bath temperature is 590-650 DEG C。
The invention has the beneficial effects as follows: simple to operate, steel plate is preheated, accelerate the speed of hot dip, improving production efficiency, hot dip is effective, and thickness of coating difference is less, it is easy to promote。
