Abstract
The invention discloses a hydrogen treatment system for strip steel acid pickling. The hydrogen treatment system comprises an acid pickling tank that is connected with an exhaust duct; the exhaust duct is further connected to a high-temperature high-pressure furnace that is connected with a water storage tank, wherein a valve is arranged on the exhaust duct. In such a manner, the hydrogen treatment system for strip steel acid pickling provided by the present invention is capable of immediately removing hydrogen formed by molecularizing partial hydrogen atoms in a strip steel acid pickling process, thereby avoiding defects, such as acid pickling bubbles, black cracks and so on, formed due to hydrogen penetrating into metals and effectively improving the yield of strip steels; such a treatment manner is environment-friendly, pollution-free, simple, safe and reliable.
Description
Technical field
The present invention relates to acid washing bath device field, particularly relate to a kind of hydrogen treat system of strip pickling.
Background technology
The rust cleaning of band steel processes mainly through Physical and chemical method, and wherein, chemical method is eliminated rust by pickling line, and rust cleaning speed is fast, rust cleaning thoroughly, and is subject to the welcome of being with steel rolling processing industry.Pickling can wash the defect such as iron scale, rust staining on raw material surface off, makes smooth surface clean, both can avoid occurring during rolling the accident such as broken belt, steel bonding, finished surface also can be made smooth, and not have blackspot rusty stain.
But also there is certain deficiency in existing acid pickling and rust removing operation, such as, because acid and exposed metal function generate hydrogen, and from acid solution hydrogen permeate in the crystal lattice of metal, and make it be out of shape, make hydrogen after distortion more to metal internal diffusion, make in metal, to create the internal stress causing hydrogen embrittlement, make the little bubbling of metallic surface formation in strip, in black minute crack after breaking, after rolling, bubble crack can extend expansion, causes the impelling strength of product to reduce.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of hydrogen treat system of strip pickling, can in strip pickling process, timely removal part hydrogen atom molecularization and the hydrogen formed, avoid because forming the defect such as pickling bubble, black crack in hydrogen molecules permeate to metal, effective yield rate improving band steel, processing mode is environment friendly and pollution-free, simply, safe and reliable.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the hydrogen treat system providing a kind of strip pickling, it is characterized in that, comprise: pickling tank, described pickling tank is connected with a gas exhaust duct, described gas exhaust duct is connected with a High Temperature High Pressure stove, and described High Temperature High Pressure stove connects a water tank, and wherein said gas exhaust duct is provided with valve.
In a preferred embodiment of the present invention, described gas exhaust duct, High Temperature High Pressure stove and water tank are sealed connection.
In a preferred embodiment of the present invention, described gas exhaust duct and the junction of pickling tank are provided with a centrifugal blower.
In a preferred embodiment of the present invention, sustainable supply water in described High Temperature High Pressure stove.
The invention has the beneficial effects as follows: the hydrogen treat system of strip pickling provided by the present invention, can in strip pickling process, timely removal part hydrogen atom molecularization and the hydrogen formed, avoid forming the defect such as pickling bubble, black crack because hydrogen atom penetrates in metal, effective yield rate improving band steel, processing mode is environment friendly and pollution-free, simply, safe and reliable.
