Brief description of the drawings
In the present invention, identical reference represents identical feature all the time, wherein：
Fig. 1 is the structural representation of strip deactivation slot of the invention.
Specific embodiment
Technical scheme is further illustrated with reference to the accompanying drawings and examples.
Refer to shown in Fig. 1, a kind of strip deactivation slot for producing fine material of the invention is located at acid
Wash, cleaning section rear, it is main include the low-temperature passivation groove 1 before being arranged in and be arranged in after high temperature it is blunt
Changing in groove 2, low-temperature passivation groove 1 has in low-temperature passivation liquid, high temperature deactivation slot 2 with high temperature passivation
Liquid, when the strip 4 after pickling, cleaning sequentially passes through low-temperature passivation groove 1, high temperature deactivation slot 2,
Chemical neutralization reaction is carried out by the pickle of low-temperature passivation liquid and the remained on surface of strip 4, is used to remove
The pickle of the remained on surface of strip 4, then the surface of strip 4 is obtained certain temperature by high temperature passivating solution
Degree, to the automatic evaporation of belt steel surface moisture.
Used as one embodiment, described low-temperature passivation groove 1 includes cell body 11, the cryostat, pressure of rectangle
Roller 12, inlet 13 and leakage fluid dram 14,12 are installed on cell body middle part, several inlets 13 and row
Liquid mouthful 14 is opened on the two side of cell body 11 respectively, and cryostat, pressure roller 12 can make to enter cell body
Operation strip in 11 is completely submerged in the low-temperature passivation liquid in cell body 11.
Equally, described high temperature deactivation slot 2 also including the high temperature 21 of rectangle, high temperature groove pressure roller 22,
Inlet high 23 and leakage fluid dram 24, high temperature groove pressure roller 21 are installed on the middle part of cell body 21, make to enter groove
Operation strip in body 21 is completely submerged in the high temperature passivating solution in cell body 21, several inlets 23
It is opened in respectively on the two side of cell body 21 with leakage fluid dram 24.
As another embodiment, by repeatedly calculating repeatedly and testing, described low-temperature passivation liquid
Temperature is 20-50 DEG C, and so relatively low temperature is conducive to the carrying out of neutralization reaction；Described high temperature is blunt
The temperature for changing liquid is 80-100 DEG C, and temperature so higher is conducive to the automatic evaporation after strip water outlet
Moisture.
In addition, being additionally provided with 3 guide rollers between described low-temperature passivation groove 1 and high temperature deactivation slot 2, rise
To the effect of strip transition between two grooves.The rear of described high temperature deactivation slot 2 is additionally provided with baking oven (figure
Not shown in).
It is of the invention as follows for producing the specific passivating method of the strip deactivation slot of fine material：
First, make to enter low-temperature passivation groove 1 through the strip 4 after pickling, cleaning, by low-temperature passivation groove 1
Interior low-temperature passivation liquid carries out reaction neutralization with the pickle of the remained on surface of strip 4, is used to remove its table
The pickle in face, the temperature of described low-temperature passivation liquid is 20-50 DEG C；
Then, then strip 4 is made to enter high temperature deactivation slot 2, it is blunt by the high temperature in high temperature deactivation slot 2
Change liquid and improve belt steel surface temperature, be used to evaporate belt steel surface moisture, the temperature of described high temperature passivating solution
Spend is 80-100 DEG C.
Finally, can also be by the warm-air drier of baking oven to from following table on the strip out of high temperature deactivation slot 2
Face carries out warm wind purging and heating, drying, so that it is guaranteed that belt steel surface moisture evaporating completely.
