Description

Technical Field

[0001] This utility model relates to the field of air-cooling equipment technology, and in particular to an air-cooling equipment for steel plate castings. Background Technology

[0002] Air-cooled equipment technology uses air as a heat transfer medium to dissipate heat through natural convection. It was widely used in data centers, industrial frequency converters, and power electronic devices in the early stages. Its core advantages are simple system structure, low cost, and no risk of coolant leakage. However, due to the limitations of air's specific heat capacity and thermal conductivity, the heat dissipation efficiency is relatively low. Air-cooled equipment technology has achieved control of heat flow on the surface of high-temperature castings. It has not only broken through the heat dissipation bottleneck of traditional air cooling at thick cross-sections of castings, but also controlled the cooling uniformity error of castings within ±3℃ through a digital twin-driven intelligent temperature control system, which has significantly improved the microstructure density and mechanical property stability of large flat castings.

[0003] When it is necessary to efficiently control the cooling rate of large steel plate castings in continuous casting, ensure the uniformity of surface and internal temperature of the casting, avoid thermal stress cracking, and optimize the metallographic structure, a dedicated air-cooling device for steel plate castings is required. This air-cooling device is a specialized cooling unit designed for large steel plate castings in continuous casting. Its core utilizes a high-precision air duct system to uniformly spray filtered and temperature-controlled compressed air onto the casting surface. Combined with dynamic air pressure control and multi-segment temperature feedback technology, it achieves gradient cooling optimization in both the thickness and planar directions of the casting. This effectively controls the cooling rate of thick-section castings to prevent internal cracks and ensures uniform cooling in thin-walled areas to avoid deformation. However, most existing air-cooling devices use fixed-angle guide vanes in the nozzles, making angle adjustment impossible. This results in low cooling uniformity, a limited range of equipment compatibility, and reduced practicality. Utility Model Content

[0022] Working principle: First, press the back side of the irregular rotating plate 9 to compress the spring column 10, causing the rotating column 11 to rotate on the outer wall of the fixed column 12. The rotating column 11 is restricted to the bottom of the inner wall of the connecting plate 3, causing the positioning column 2 8 to disengage from the positioning hole 2 6, thereby releasing the fixation of the connecting column 5. Rotate the rotating disk 7, which drives the connecting column 5 to rotate. The connecting column 5 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the guide plate 13 to rotate. After rotating to a suitable angle, release the spring column 10, allowing the positioning column 2 8 to slide into the positioning hole 2 6 and fix the connecting column 5.

First, slide the sealing plate 201 into the notch at the top of the air box 1. The limiting plate 202 prevents the sealing plate 201 from moving further downward. Insert the positioning pin 206 into the positioning hole 205, so that the locking block 207 slides into the sliding groove 204. The locking block 207 enters the sliding groove 203. Rotate the positioning pin 206 to make the locking block 207 slide in the sliding groove 203 and stop in the sliding groove 308. This fixes the sealing plate 201 to the top of the air box 1 and seals the air box 1, preventing gas from escaping. Conversely, the sealing plate 201 can be removed, which facilitates the quick disassembly of the cover plate, making it easier to clean the cooling air chamber, improving work efficiency and practicality.
