Description
Technical field
The invention belongs to hot radical galvanized sheets and hot radical aluminum-zinc alloy silicon plate to produce and process technical field, in particular, provide one kind
Integrated hot radical galvanized sheet and hot radical aluminum-zinc alloy silicon plate are suitable for during old improvement of manufacturing line in the production method of one.
Background technique
Currently, domestic hot radical zinc-plated board production line and hot radical aluminum-zinc alloy silicon board assembly line mainly based on individually building, have
A small amount of transformation production line is that two kinds of sheet production methods combine in a production line.It plates about hot radical involved in the pertinent literature
The production method that zinc and hot radical aluminum-zinc alloy silicon are integrated in one.In document, (hot galvanizing changes hot-dip aluminizing zinc unit technique and sets Xiong Junwei
Alternative type, steel rolling, 2017,34 (6)) in mention for one galvanization production line of certain steel mill being transformed into and have production hot galvanizing and hot dip
The ability of aluminium zinc product, but the kind of its production is more rudimentary, the low product of intensity.
In view of above-mentioned data as it can be seen that about production two kinds of plate hot radical coating production line technology certain technologies at
It is ripe, but can satisfy the production of more multi items after improvement there are also can centainly improve place on certain products or parameter.
Summary of the invention
The object of the present invention is to provide a kind of integrated hot radical galvanized sheets and hot radical aluminum-zinc alloy silicon plate in the production method of one.
The technical scheme is that
Mainly there are CQ, DQ, C-Mn, HSLA, DP, HSS, UHSS etc. for the zinc-plated steel plate with hot radical aluminum-zinc alloy silicon of hot radical,
The maximum tensile strength of product is 800MPa, and steel strip thickness is 0.8~6.0mm, and thickness of coating is 60~600g/m2.Specific work
Steps are as follows for skill:
1) uncoiling is welded, cleaning, the conventional treatments such as entry loop；
2) heat stove heating: heating furnace uses segmentally heating mode, while meeting the zinc-plated and requirement of aluminum-zinc alloy silicon temperature,
At 440 DEG C~480 DEG C, aluminum-zinc alloy silicon temperature is controlled at 540 DEG C~600 DEG C for zinc-plated temperature control；
3) GI pots or GL pots and air knife:, completion plating GI pots or GL pots mobile by pot body mobile device is required according to different
Zinc or aluminum-zinc alloy silicon, and thickness of coating is controlled by air knife, with a thickness of 60~600g/m2；
4) it cooling, finishing straightening, passivation, inspection, oiling and the conventional treatments such as batches, obtains different performance coil of strip.
According to the production method of invention, 2) heating stove heating, whether unlatching by controlling bringing-up section, control not equality of temperature
Degree, at 440 DEG C~480 DEG C, optimum temperature is 450 DEG C for zinc-plated temperature control；Aluminum-zinc alloy silicon temperature is controlled at 540 DEG C~600 DEG C,
Optimum temperature is 560 DEG C.
According to the production method of invention, 3) GI pots or GL pots and air knife: needing to produce galvanized sheet, GI pots in working position
On, GL pots on inoperative position；Needing to produce aluminum-zinc alloy silicon plate, GL pots on working position, GI pots are moved on inoperative position.
It can be mutually transformed into producing line between GI pots and GL pots, while same set of air knife can be shared.
Compared with prior art, the present invention has following technical effect:
1, the plating piece product category of technique of the invention preparation is more, and the thickness range for including is wide, and the intensity of product is high, coating
Thickness range is big.
2, the present invention is segmented by thinner heating furnace, makes the more acurrate of heating and temperature control, meet well it is zinc-plated and
The temperature requirement of aluminum-zinc alloy silicon.
3, the present invention is switched over by mobile GI pots and GL pots to produce galvanized sheet and aluminum-zinc alloy silicon plate, product category compared with
Single production technology is more, can meet market demands.
