Description

Technical Field

[0001] This patent discloses a heat storage rapid evaporation tube, which belongs to the field of metallurgy industry and the field of deep processing of stainless steel materials. This patent is to evaporate the water quickly after coating the surface of stainless steel wire, eliminate the disadvantages of surface adhesion lubricant, ensure that the coated steel wire can stably enter the mold box after drying, and realize a stable and continuous drawing process. Background Art

[0002] Stainless steel refers to a metal material with high chemical stability in air, water, acidic solutions and other corrosive media.

[0003] For the processing of stainless steel materials, it is necessary to clean the oxide layer on the surface of the material, or to provide corrosion resistance protection for the intermediates in each processing link to improve the surface quality of the stainless steel. For the process of using molds to pressure process stainless steel wires, the removal or isolation of the oxide layer on the surface of the stainless steel mainly relies on molten salt alkali immersion, pickling and other processes, and then the stainless steel wire is drawn. This surface treatment link makes the processing link inefficient and the mold consumption is large, so it is inclined to use means of corrosion resistance protection for stainless steel materials in each link.

[0004] In the field of deep processing of stainless steel long wires, the stainless steel material is subjected to pressure processing through a die to plastically deform and draw it thin, which requires the joint cooperation of the die, wire drawing machine equipment, lubrication, and surface treatment methods. In this link, it is necessary to control the water content on the surface of the stainless steel material so that the water can evaporate quickly after the stainless steel wire surface coating is lubricated, eliminating the problem of surface adhesion of lubricants, ensuring that the steel wire can stably enter the die and realize continuous processing links.

[0005] In the stainless steel wire processing technology, the wire surface coating control technology has become a key technical means. The viscous water-soluble organic coating is applied to the surface of the steel wire, and the coating dries quickly by rapidly evaporating the water in the coating, thereby forming a stable corrosion-resistant lubricating coating on the surface of the stainless steel wire. Among them, the evaporation rate of water will affect the actual drawing line speed and the efficiency of continuous production.

[0006] At present, the surface of stainless steel wire after hot air circulation drying contains residual moisture. After entering the wire drawing machine, the lubricating powder forms a bond on the surface of the stainless steel wire, causing the stirring motor of the mold box to overload and damage, affecting continuous production. Therefore, it is necessary to develop a heat storage rapid evaporation tube to solve the drying problem of the surface of the stainless steel wire after coating treatment. In order to achieve the above-mentioned use needs and corresponding requirements, a heat storage rapid evaporation tube based on the above-mentioned situation and needs is specially invented. Utility Model Content

[0007] The technical problem to be solved by this patent is to provide a heat storage rapid evaporation tube to solve the drying problem of the surface of the stainless steel wire after coating treatment, and to improve the production efficiency and stability of the stainless steel wire.

[0008] The utility model provides a heat storage rapid evaporation tube, which is a steel tube with two openings at both ends. Both ends of the steel tube are provided with end covers, and the inner sides of the end covers are provided with internally convergent guiding slope structures, and the inner sides of the two guiding slope structures are provided with two lateral interfaces;

[0009] The downstream interface of the two interfaces is used for high-temperature dry atmosphere to enter the heat storage rapid evaporation tube, and the upstream interface of the two interfaces is used for atmosphere to flow out of the heat storage rapid evaporation tube;

[0010] The flow direction of the high-temperature dry atmosphere in the heat storage rapid evaporation tube is opposite to the movement direction of the stainless steel long material.

[0011] The two interfaces of the heat storage rapid evaporation tube are connected to the hot air circulation machine, and the drying atmosphere becomes an atmosphere containing higher moisture in the heat storage rapid evaporation tube, flows into the hot air circulation machine from the upstream interface of the heat storage rapid evaporation tube, and after being dehydrated by the hot air circulation machine, enters the heat storage rapid evaporation tube through the downstream interface of the heat storage rapid evaporation tube.

[0012] The inner sides of both ends of the heat storage rapid evaporation tube are provided with guiding slope structures, which are used to reduce the difficulty of threading the stainless steel long material and to increase the threading speed of the stainless steel long material.

[0013] Both ends of the heat storage rapid evaporation tube are provided with end caps with a central hole. The central hole structure is a channel for the stainless steel long material to enter and leave the heat storage rapid evaporation tube. The end caps are used to reduce the overflow degree of the high-temperature dry atmosphere and improve the recycling ratio of the high-temperature dry atmosphere.

[0014] Based on the structure of the stainless steel long product production line, the heat storage rapid evaporation tube structure is linear or curved.

[0015] The surface of the heat storage rapid evaporation tube is covered with a heat insulation layer and a protective net.

[0016] After the stainless steel wire is continuously unwound, cleaned, washed with hot water, and coated with temperature control, a heat storage rapid evaporation tube as described in this patent is added at the outlet, so that after the circulating hot air drying treatment, the stainless steel wire enters the first die box of the linear continuous wire drawing machine in a reliable dry surface state, ensuring stable production at the rated drawing speed.

[0017] The heat storage rapid evaporation tube is a steel tube with a length of 2 meters and a diameter of about 100 mm; both ends of the heat storage rapid evaporation tube have end cover structures to reduce the loss of circulating atmosphere; both ends of the heat storage rapid evaporation tube have an internally contracted guide slope structure, and the inner side of the guide slope has two interfaces with a diameter of about 20 mm, and the interfaces at both ends are connected to the hot air circulation machine to realize a countercurrent high-temperature dry atmosphere inside the heat storage rapid evaporation tube.

[0018] After high-temperature coating, the stainless steel wire enters the heat storage rapid evaporation tube. The high-temperature atmosphere inside the heat storage rapid evaporation tube causes the moisture in the viscous colloidal solution on the surface of the steel wire to evaporate rapidly, so that the surface of the coated stainless steel wire is completely dried after being treated by the heat storage rapid evaporation tube described in this patent.

[0028] See also Figure 1 , this patent provides an embodiment and technical solution:

[0029] like Figure 1 As shown, the heat storage rapid evaporation tube structure is a steel tube structure with openings at both ends. Both ends of the steel tube have end covers with central holes. The inner sides of both ends of the steel tube have contracted guide slope structures.
