Description

Technical Field

[0001] The utility model relates to the technical field of converter slag blocking, in particular to a self-made converter slag blocking cap. Background Art

[0002] The converter is a type of steelmaking furnace. Usually, the furnace body is cylindrical and mounted on a horizontal axis frame, which can rotate. The production process of the converter includes the slag unloading step. The slag unloading of the converter is divided into three situations: slag unloading before steelmaking, slag rolling in the late stage of steelmaking, and slag unloading at the end of steelmaking. In the early stage of steelmaking from the converter, a slag cap is usually plugged into the converter tapping port, and then the converter is gradually tilted. When the slag floats above the horizontal plane of the tapping port, the molten steel rushes out, and the steel slag cap is flushed into the ladle at the same time, thereby avoiding slag being brought into the ladle.

[0003] At present, the slag blocking in front of the converter is usually set up with a slag blocking cap. During operation, the front half of the slag blocking cap made of refractory material is inserted into the steel tapping hole and stuck at the outer mouth of the steel tapping hole. However, the slag blocking cap and the steel tapping hole are not well sealed, so that the slag blocking cap is not firmly plugged, which causes the slag blocking cap to detach when the converter tilts, and thus cannot effectively play the role of early slag blocking.

[0004] Therefore, we proposed a self-made converter slag retaining cap to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a self-made converter slag stopper to solve the problem that the slag stopper in front of the converter is usually set up with a slag stopper. During operation, the front half of the slag stopper made of refractory material is inserted into the steel tapping hole and stuck at the outer mouth of the steel tapping hole. However, since the sealing fit between the slag stopper and the steel tapping hole is not good enough, the slag stopper is not firmly plugged, which causes the slag stopper to detach when the converter is tilted, thereby failing to effectively play the role of early slag blocking.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-made converter slag stop cap, comprising a converter body and a tapping port arranged at one end of the outer wall of the converter body, a slag stop assembly being fixedly installed in the notch of the tapping port, and the slag stop assembly being suitable for sealing and fixing the tapping port;

[0007] The slag blocking assembly includes a fixing mechanism and a conical cylinder fixedly installed in the middle of one end of the fixing mechanism. The upper and lower sides of one end of the fixing mechanism are respectively threadedly fixed with mounting mechanisms. The fixing mechanism drives the conical cylinder to be embedded in the inner cavity of the slot of the steel outlet, and the mounting mechanism is threadedly fixed on the outer wall of the steel outlet.

[0008] Preferably, the fixing mechanism includes a fitting block and concave blocks fixedly mounted on the upper and lower sides of one end of the fitting block, and circular thread grooves are respectively provided at both ends of one side of the inner wall of the concave block.

[0009] Preferably, limiting grooves are provided in the middle of both sides of the inner wall of the concave block, and a fixed threaded column is threadedly connected in the inner cavity of the circular threaded groove.

[0010] Preferably, the mounting mechanism includes a semicircular clamping block and an extension block fixedly mounted in the middle of one side of the upper end of the semicircular clamping block.

[0011] Preferably, a corresponding screw groove is provided in the middle of one end of the extension block, and limit blocks are fixedly installed on both sides of the upper end of the outer wall of the extension block.

[0012] Preferably, docking plates are fixedly installed on both sides of the lower end of the semicircular block, and circular grooves are linearly and evenly spaced on the upper ends of the docking plates, and threaded columns are movably installed in the inner cavities of the circular grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The operator inserts the tapered cylinder fixedly installed in the middle of one end of the bonding block into the inner cavity of the tapping port. After the tapping port is blocked, the semicircular blocks threadedly installed on both sides of one end of the bonding block are moved with the tapping port as the center, so that the docking plates of the semicircular blocks on both sides of one end of the bonding block are bonded together. The threaded column passes through the inner cavity of the circular groove, and the threaded column thread is pressed tightly into the inner cavity of the circular groove by using a nut, thereby completing the fixation between the docking plates of the semicircular blocks on both sides of one end of the bonding block, and at the same time achieving the fixed installation of the bonding block and the tapered cylinder, thereby preventing the slag in the furnace from entering the ladle in the early stage of tapping and improving product quality.

[0015] 2. The operator pulls down the semicircular block so that it slides in the inner cavity of the concave block, and at the same time makes the inner wall of the semicircular block fit into the outer wall of the steel outlet. The fixed threaded column is screwed from the corresponding screw groove into the inner cavity of the circular thread groove, thereby fixing the extension block in the inner cavity of the concave block to complete the position adjustment of the fitting block.

The upper end of the docking plate 335 is linearly and evenly spaced with circular grooves 336. A threaded column 337 is movably installed in the inner cavity of the circular groove 336. The lower end of the threaded column 337 is installed in the inner cavity of the circular groove 336 by a nut thread limiter.

[0025] In this embodiment, when the operator is blocking the steel outlet 2, he can insert the conical cylinder 32 fixedly installed in the middle of one end of the fitting block 311 into the inner cavity of the steel outlet 2, so that the steel outlet 2 is blocked. Then, the semicircular clamping blocks 331 threadedly installed on both sides of one end of the fitting block 311 are moved around the steel outlet 2 as the center, so that the docking plates 335 of the semicircular clamping blocks 331 on both sides of one end of the fitting block 311 are fitted together. The operator passes the threaded column 337 through the inner cavity of the steel outlet 2. The inner cavity of the circular groove 336 is tightened by using a nut to press the threaded column 337 into the inner cavity of the circular groove 336, thereby completing the fixation between the docking plates 335 of the semicircular clamping blocks 331 on both sides of one end of the bonding block 311. This setting can enable the semicircular clamping blocks 331 on both sides of one end of the bonding block 311 to clamp and fix the outer surface of the steel outlet 2, thereby realizing the fixed installation of the bonding block 311 and the conical cylinder 32, thereby preventing the slag in the furnace from entering the ladle in the early stage of steel tapping and improving product quality.

[0026] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 The fixing mechanism 31 includes a fitting block 311 and concave blocks 312 fixedly installed on the upper and lower sides of one end of the fitting block 311. Circular thread grooves 313 are respectively provided at both ends of the inner wall of one side of the concave block 312.

[0027] Limiting grooves 314 are provided in the middle of both sides of the inner wall of the concave block 312 , and a fixing threaded column 315 is threadedly connected in the inner cavity of the circular threaded groove 313 .

[0028] The mounting mechanism 33 includes a semicircular clamping block 331 and an extension block 332 fixedly mounted in the middle of one side of the upper end of the semicircular clamping block 331.

[0029] The extension block 332 is fixedly installed in the inner cavity of the concave block 312 by threading the fixing thread column 315 into the inner cavity of the circular thread groove 313 and the corresponding thread groove 333 .

[0030] A corresponding screw groove 333 is defined in the middle of one end of the extension block 332 , and limit blocks 334 are fixedly mounted on both sides of the upper end of the outer wall of the extension block 332 .

[0032] In this embodiment: when the operator adjusts the semicircular blocks 331 on both sides of one end of the bonding block 311, the operator pulls down the semicircular blocks 331 so that the semicircular blocks 331 slide in the inner cavity of the concave block 312, and at the same time makes the inner wall of the semicircular blocks 331 fit the outer wall of the steel outlet 2. After adjusting the position, the operator can screw the fixed threaded column 315 from the corresponding screw groove 333 into the inner cavity of the circular threaded groove 313, thereby fixing the extension block 332 in the inner cavity of the concave block 312 to complete the position adjustment of the bonding block 311.

Then, the semicircular clamping blocks 331 threadedly installed on both sides of one end of the fitting block 311 are moved around the steel outlet 2. When adjusting the fitting block 311, the semicircular clamping block 331 can be pulled down to make the semicircular clamping block 331 slide in the inner cavity of the concave block 312, and at the same time, the inner wall of the semicircular clamping block 331 is fitted with the outer wall of the steel outlet 2. After adjusting the position, the operator can screw the fixed threaded column 315 from the corresponding screw groove 333 into the inner cavity of the circular thread groove 313, thereby fixing the extension block 332 It is fixed in the inner cavity of the concave block 312 to complete the position adjustment of the bonding block 311, so that the docking plates 335 of the semicircular blocks 331 on both sides of one end of the bonding block 311 are fitted together.
