Description

Technical Field

[0001] This utility model mainly relates to the technical field of refractory material preparation, specifically a wet material pressing device for high-quality steel ladle dredging sand. Background Technology

[0002] In the steel smelting industry, the ladle, as a crucial container for receiving and transporting molten steel at high temperatures and for subsequent refining and casting operations, directly impacts steel quality, production efficiency, and equipment safety through its performance and operational stability. Ladle runner sand is an essential functional material ensuring smooth steel discharge from the ladle. Laden inside the ladle nozzle seat bricks, it forms a dense protective layer when the molten steel is stationary, preventing leakage and oxidation. During casting, it quickly disintegrates, ensuring a smooth flow of molten steel. High-quality ladle runner sand has stringent requirements for particle size distribution, compositional uniformity, refractoriness, and corrosion resistance. Its production process involves multiple steps, including raw material screening, mixing, wet material preparation, pressing, and drying / sintering. Among these, the wet material pressing stage is critical, directly affecting the particle structure, density, and final performance of the runner sand.

[0003] Traditional wet material pressing methods rely heavily on manual labor or simple semi-automatic equipment. Manual operation requires workers to fill and press the wet material manually using simple molds and tools, resulting in low efficiency. Furthermore, manual force application makes it difficult to ensure uniform and stable pressure, leading to inconsistent density and irregular shapes in the pressed wet material blocks. This can cause cracking and deformation during subsequent sintering, affecting the quality of the finished casting sand. While simple semi-automatic equipment improves production efficiency to some extent, it often suffers from insufficient pressing precision, low automation, and an inability to flexibly adjust pressing parameters according to different product requirements. Consequently, it struggles to meet the demands of modern steel production for large-scale, high-quality casting sand production.

[0004] Therefore, developing a device that can efficiently, accurately, and automatically press high-quality steel ladle slurry wet material has become an urgent technical problem to be solved in the fields of iron and steel smelting and related refractory material production. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a high-quality wet material pressing device for steel ladle drainage sand, so as to solve the technical problems mentioned in the background art.

A supporting base plate is slidably connected to the side wall of the first limiting slide rods. Second limiting slide rods are symmetrically arranged at both ends of the wet material placement cross plates and on one side of the first limiting slide rods. Wet material pressing cross plates are slidably connected to the outer wall of the second limiting slide rods.

[0008] Preferably, the top of the second limiting slide rod passes through the top of the support plate.

[0009] Preferably, the bottom of the wet material pressing cross plate is provided with a stamping end.

[0010] Preferably, a hydraulic cylinder is provided at the top of the support plate, and the actuating end of the hydraulic cylinder is connected to the top of the wet material pressing cross plate.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] like Figures 1 to 4 As shown, a high-quality steel ladle sand-draining wet material pressing device includes a base 10, with support rods 11 on both side walls of the base 10, and a support plate 12 on the top of the support rods 11. First limiting slide rods 13 are symmetrically arranged on both sides of the base 10, and a wet material placement cross plate 14 is provided on the top of the first limiting slide rods 13. A supporting base plate 15 is slidably connected to the side wall of the first limiting slide rods 13. Second limiting slide rods 16 are symmetrically arranged at both ends of the wet material placement cross plate 14 and on one side of the first limiting slide rods 13. A wet material pressing cross plate 17 is slidably connected to the outer wall of the second limiting slide rods 16.

[0024] The top of the second limiting slide bar 16 passes through the top of the support plate 12.

[0025] The bottom of the wet material pressing horizontal plate 17 is provided with a stamping end 171.

[0026] A hydraulic cylinder is installed at the top of the support plate 12, and the actuating end of the hydraulic cylinder is connected to the top of the wet material pressing cross plate 17.

[0027] The top of the wet material placement plate 14 is provided with multiple pressing through holes 141, which are correspondingly set with the stamping end 171.

[0028] A hydraulic cylinder is provided on the top of the base 10, and the actuator end of the hydraulic cylinder is connected to the bottom of the support base plate 15.

[0029] Multiple placement holes 142 are provided at both ends of the wet material placement horizontal plate 14, and the placement holes 142 are connected to the first limiting slide rod 13 and the second limiting slide rod 16.

[0030] It should be noted that, in this embodiment, the high-quality steel ladle guiding sand wet material pressing device is installed in the designated working area, ensuring that the base 10 is placed stably, the support rod 11 is vertically connected to the side walls at both ends of the base 10, and the support plate 12 is horizontally fixed to the top of the support rod 11; check that the first limiting slide rod 13 is symmetrically inserted through both sides of the base 10 and is firmly connected, the wet material placement horizontal plate 14 is installed on the top of the first limiting slide rod 13, the support base plate 15 is slidably connected to the side wall of the first limiting slide rod 13 and the initial position is at a suitable height; the second limiting slide rod 16 is symmetrically arranged at both ends of the wet material placement horizontal plate 14 and the top of the second limiting slide rod 16 is inserted through the top of the support plate 12, and the wet material pressing horizontal plate 17 is slidably connected to the outer wall of the second limiting slide rod 16; confirm that the hydraulic cylinders on the top of the support plate 12 and the top of the base 10 are correctly installed, and that the actuators of the hydraulic cylinders are well connected to the top of the wet material pressing horizontal plate 17 and the bottom of the support base plate 15, respectively.

[0031] The hydraulic cylinder at the top of the base 10 is activated. The actuator of the hydraulic cylinder pushes the support base plate 15 to slide upward along the first limit slide bar 13 until the support base plate 15 rises to make close contact with the bottom of the wet material placement horizontal plate 14, providing stable support for the wet material placement horizontal plate 14. At the same time, it is used to close the multiple pressing through holes 141 that pass through the top of the wet material placement horizontal plate 14.

[0032] The operator places the prepared wet material evenly into the inner wall of the multiple pressing through holes 141 at the top of the wet material placement plate 14, ensuring that the wet material is evenly distributed and avoiding accumulation or gaps, so as to ensure that each part is subjected to uniform force during the subsequent pressing process.

[0033] The hydraulic cylinder at the top of the support plate 12 is activated, and the actuator of the hydraulic cylinder pushes the wet material pressing plate 17 to slide downward along the second limit slide bar 16; the stamping end 171 at the bottom of the wet material pressing plate 17 moves downward accordingly and gradually enters the pressing through hole 141 corresponding to the top of the wet material placing plate 14, applying pressure to the wet material placed on the wet material placing plate 14; during the pressing process, the wet material is gradually pressed into the required shape under the pressure of the stamping end 171.

[0034] After the wet material is pressed to the set shape and density, the wet material pressing plate 17 and the support base plate 15 move downwards a short distance at the same time, and the pressed wet material is demolded. Then, the hydraulic cylinder at the top of the support plate 12 is closed, and the hydraulic cylinder actuator drives the wet material pressing plate 17 to slide upwards along the second limit slide bar 16, and the stamping end 171 exits from the pressing through hole 141.

[0035] When the hydraulic cylinder at the top of the base 10 is closed, the actuator of the hydraulic cylinder drives the support base plate 15 to slide downward along the first limit slide bar 13, separating it from the wet material placement plate 14. At this time, the pressed wet material is distributed on the top of the support base plate 15, and the operator can remove the pressed high-quality steel ladle guiding sand from the wet material placement plate 14 to complete one pressing process.

[0036] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
