Problems solved by technology

[0002] Bright steel strips and manganese steels of various specifications in fields such as mop rods, luggage pipes, and furniture pipes are widely used. It is prone to rust, which affects its service life. The damage of a single component will directly affect the use of the entire luggage and furniture, increasing the cost of use; second, luggage tubes, furniture tubes, etc. are usually used in conjunction with other pipe fittings. When a pipe fitting or several pipe fittings are rusted or the surface is rough, it will affect the smoothness of its sliding and reduce the practicability

Embodiment 1

[0027] The present embodiment bright tube body processing technology, combines figure 1 , including feeding roll 1, pickling tank 2, cleaning tank 4 and rolling mill 7 installed in sequence; a hot box 3 is arranged above the pickling tank 2, and a guide roll with the bottom immersed in the pickling solution is arranged in it -21, the hot box 3 forms a closed structure above the pickling tank 2, and keeps the temperature in the pickling tank 2 at 55-60°C, and the humid and hot atmosphere of acidification is conducive to the acidification; (volume concentration) of hydrochloric acid, the wool material A supplied by the feed roller 1 stays in the pickling tank 2 for 3-4 minutes to obtain the acidified material B, which is sent into the cleaning tank 4, and the cleaning solution in the cleaning tank 4 Under the action of the acidification material B, the acid on the surface of the acidizing material B can be removed to form a crude product, wherein a guide roller 41 formed by a pa...

Embodiment 2

[0032] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that two rolling mills are arranged between the cleaning mechanism 5 and the rolling mill 7, and the cleaned rough products are rolled to 1.8mm and 0.5mm in turn for pre-extrusion , and then sent to the joint rolling mill 7 for thinning to a set thickness.

[0033] The crude product is first pre-extruded in one or more rolling mills, and then sent to the joint rolling mill for final thinning. The pipes formed by this method have uniform quality and stable mechanical properties.

Embodiment 3

[0035] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that a heat treatment furnace 9 is arranged behind the rolling mill 7, and the initial product D is sent into the heat treatment furnace 9, and is treated at 600° C. for 24 hours under the protection of liquid nitrogen. ,cool down. Specifically in this embodiment, combined with image 3 and Figure 4 , the heat treatment furnace 9 includes an outer cover 91, an inner cover 92, a liquid nitrogen channel 93 and a base 94, the inner cover 92 is fixed on the base 94, the outer cover 91 is set on the inner cover 92, and the top of the outer cover 92 communicates with the liquid nitrogen channel 93, and the liquid nitrogen Burn NH through a calciner 3 , and feed into between the inner cover 92 and the outer cover 91 through the liquid nitrogen channel 93, and the inner wall of the outer cover 91 is provided with a heating wire 95, and the heating wire 95 is energize...

Abstract

The invention relates to a bright pipe body processing technology, which belongs to the technical field of metal rolling. It includes feeding rolls, pickling tanks, cleaning tanks and rolling mills installed in sequence; there is a hot box above the pickling tank, and the hot box forms a closed structure above the pickling tank, and the wool supplied by the feeding rolls is in the pickling tank The acidified material is obtained, and the acidified material is sent to the cleaning tank to remove the surface acid to form a crude product; the crude product is sent to the joint rolling mill. Applying the invention to the processing of steel strips and pipe fittings has the advantages of short processing flow and high brightness of finished products.

Description

technical field [0001] The invention relates to a bright pipe body processing technology, which belongs to the technical field of metal rolling. Background technique [0002] Bright steel strips and manganese steels of various specifications in fields such as mop rods, luggage tubes, furniture tubes, etc. It is prone to rust, which affects its service life. The damage of a single component will directly affect the use of the entire luggage and furniture, increasing the cost of use; second, luggage tubes, furniture tubes, etc. are usually used in conjunction with other pipe fittings. When a certain pipe fitting or several pipe fittings are rusted or the surface is rough, it will affect the smoothness of its sliding and reduce its practicability. [0003] Based on this, this application is made. Contents of the invention [0004] In order to overcome the above-mentioned defects in the existing pipe strips, the present invention provides a bright pipe body processing equipm...
