Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of steel liners, and particularly to a heat treatment device and method for steel liners. Background Art

[0002] A steel liner is a liner made of steel, usually installed on the inner wall of mechanical equipment, pipelines or containers to protect the internal structure of the equipment from damage by external factors such as wear, corrosion, high temperature, impact, etc. Steel liners can be classified into flat steel liners, curved steel liners, and cylindrical steel liners, etc. Among them, cylindrical steel liners are usually used for the circular parts of equipment and can completely fit the inner wall of the equipment. During the heat treatment process of cylindrical steel liners, corresponding heat treatment equipment is required.

[0003] Currently, when using a heat treatment device to perform quenching heat treatment on cylindrical steel liners, generally a hanging plate or a hanging basket is used to immerse multiple evenly stacked cylindrical steel liners in the heat treatment box. In this kind of heat treatment box, by setting stirring blades in the heat treatment box, the water flow rate outside the cylindrical steel liners can be accelerated to improve the heat treatment efficiency of the steel liners. In fact, this method does not significantly accelerate the water flow rate inside the cylindrical steel liners, resulting in a large difference in the heat treatment efficiency between the inside and outside of the cylindrical steel liners and prolonging the heat treatment time of the heat treatment device for the cylindrical steel liners.

[0037] Embodiment 1

[0038] Referring to Figures 1 - 6 and Figure 8 , an embodiment of the present invention provides a heat treatment device for a steel lining plate, including: a heat treatment unit 100 and a uniform flow guiding unit 200.

[0039] Among them, the heat treatment unit 100 includes a heat treatment box 101 and a hanging plate 102 located on the heat treatment box 101. A foot pad is fixedly arranged on the lower side of the hanging plate 102. On the one hand, it can ensure that the hanging plate 102 and the cylindrical steel lining plate 103 are suspended, ensuring that water can flow normally on both the upper and lower sides of the two. On the other hand, it can prevent the waterproof extrusion switch 213 from being damaged due to excessive extrusion force. A plurality of uniformly distributed cylindrical steel lining plates 103 are placed on the hanging plate 102. A plurality of groups of uniformly distributed supporting brackets 104 are fixedly arranged at the center of the upper side wall of the hanging plate 102. Each cylindrical steel lining plate 103 is placed on the corresponding supporting bracket 104. The arrangement of the supporting brackets 104 can assist in supporting the cylindrical steel lining plate 103. A plurality of groups of uniformly distributed transverse through-holes are formed in the hanging plate 102, and the transverse through-holes are arranged staggered with the supporting brackets 104. Through the arrangement of the transverse through-holes, it is ensured that the water below the hanging plate 102 can flow upward through the transverse through-holes. A plurality of groups of uniformly distributed through-holes 106 are penetrated through the upper side wall of each supporting bracket 104, and a plurality of groups of uniformly distributed strip-shaped openings 105 are formed on both sides of the supporting bracket 104. Through the arrangement of the through-holes 106 and the strip-shaped openings 105, the water flow can pass through the through-holes 106 and the strip-shaped openings 105 to pass through the supporting bracket 104, ensuring that the contact surface between the cylindrical steel lining plate 103 and the supporting bracket 104 is in contact with water and undergoes heat treatment;

[0040] Secondly, there is a uniform flow guiding unit 200, which includes a double-axis waterproof hydraulic push rod 201 embedded and installed at the center of the suspension plate 102. Rectangular openings are provided through both sides of the suspension plate 102. The output shafts of the double-axis waterproof hydraulic push rod 201 are fixedly connected with a moving seat 202 slidably connected to the rectangular openings. Symmetrically-positioned guide rods 203 are fixedly arranged in each rectangular opening. Each moving seat 202 is slidably sleeved on the guide rod 203. The arrangement of the guide rod 203 can guide and limit the movement of the moving seat 202 within the rectangular opening. A corresponding moving plate 205 is arranged on the moving seat 202. A rotating rod 206 is rotatably connected to each moving plate 205. One end of the rotating rod 206 close to the center of the suspension plate 102 penetrates through the moving plate 205 and is fixedly connected with a spiral flow guiding vane 207. A pressing convex block 211 is rotatably sleeved on the rotating rod 206. The pressing convex block 211 is located between the moving plate 205 and the spiral flow guiding vane 207. Through the arrangement of the pressing convex block 211, the cylindrical steel lining plate 103 can be limited to a certain extent to prevent the cylindrical steel lining plate 103 from moving back and forth under the impact of water flow during heat treatment. Multiple groups of uniformly distributed through holes 212 are provided through both the pressing convex block 211 and the moving plate 205. The arrangement of the through holes 212 ensures that water flow can directly penetrate the moving plate 205 and the pressing convex block 211 and enter the interior of the cylindrical steel lining plate 103.

[0041] Next, a transmission sprocket 208 is fixedly sleeved on the end of the rotating rod 206 far from the cylindrical steel lining plate 103. Multiple transmission sprockets 208 are connected by a transmission chain 209. Each transmission chain 209 and transmission sprocket 208 are made of heat-resistant steel. The transmission chain 209 and transmission sprocket 208 made of heat-resistant steel will not undergo serious deformation in a high-temperature environment, ensuring that both can drive multiple rotating rods 206 to rotate simultaneously. Uniformly distributed anti-slip patterns are provided on both the transmission chain 209 and the transmission sprocket 208. The arrangement of the anti-slip patterns improves the transmission stability between the transmission chain 209 and the transmission sprocket 208. A waterproof motor 210 is fixedly installed on each moving plate 205. The waterproof motor 210 is made of high-temperature resistant insulating material and can work in an underwater and high-temperature environment. Its model is Danfoss High-Temperature Electric Motors, suitable for underwater use, with a maximum temperature resistance of 250°C. The output shaft of the waterproof motor 210 is fixedly connected to the top end of one of the rotating rods 206. A waterproof extrusion switch 213 electrically connected to the waterproof motor 210 is fixedly installed on the lower side wall of the moving seat 202. The waterproof extrusion switch 213 is used in a waterproof and high-temperature environment and is controlled wirelessly with the waterproof motor. Its model is WFG Series.

[0042] A heat treatment method for steel lining plates, the heat treatment method is applicable to any of the above heat treatment devices, and the heat treatment method includes the following steps:

[0043] S1: Place the cylindrical steel liner 103 to be heat-treated on the corresponding support bracket 104. The double-axis waterproof hydraulic push rod 201 controls the rotating rod 206 and the spiral guide vane 207 to insert into the cylindrical support bracket 104, and put the hanging plate 102 together with the cylindrical steel liner 103 into the heat treatment box 101;

[0044] S2: When the hanging plate 102 drives the cylindrical steel liner 103 to immerse in the bottom of the heat treatment box 101, the waterproof extrusion switch 213 arranged at the bottom end of the hanging plate 102 is extruded to control the spiral guide vane 207 to accelerate the water flow rate inside the cylindrical steel liner 103;

[0045] S3: After the heat treatment is completed, the hanging plate 102 and the cylindrical steel liner 103 are lifted, the waterproof extrusion switch 213 is restored, and the waterproof motor 210 is turned off.

[0046] During use, place the cylindrical steel liner 103 to be heat-treated on the corresponding support bracket 104. The double-axis waterproof hydraulic push rod 201 controls the rotating rod 206 and the spiral guide vane 207 to insert into the cylindrical support bracket 104, and put the hanging plate 102 together with the cylindrical steel liner 103 into the heat treatment box 101. When the hanging plate 102 drives the cylindrical steel liner 103 to immerse in the bottom of the heat treatment box 101, the waterproof extrusion switch 213 arranged at the bottom end of the hanging plate 102 is extruded, and it will drive the multiple rotating rods 206 and the spiral guide vanes 207 to rotate through the waterproof motor 210. As the spiral guide vane 207 continuously guides the water flow into the inside of the cylindrical steel liner 103, it can improve the heat treatment efficiency of the water flow on the inside of the cylindrical steel liner 103, greatly shorten the difference in the quenching heat treatment efficiency between the inside and outside of the cylindrical steel liner 103, and thus shorten the heat treatment time of the heat treatment equipment for the cylindrical steel liner 103.

[0047] Embodiment 2

[0048] Refer to Figure 7 , the difference from Embodiment 1 is that: A plurality of uniformly distributed propeller blades 214 are fixedly connected to each rotating rod 206, and each group of propeller blades 214 is arranged between the moving plate 205 and the spiral guide vane 207; By arranging a plurality of uniformly distributed propeller blades 207 on the rotating rod 206, when the rotating rod 206 rotates, the propeller blades 214 thereon rotate with the rotating rod 206, accelerating the water flow rate between the moving plate 205 and the spiral guide vane 207, and can cooperate with the spiral guide vane 207 to accelerate the water flow rate of the cylindrical steel liner 103, ensuring the uniformity of the heat treatment efficiency inside and outside the cylindrical steel liner 103.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
