Ingot cooling method and water circulation cooling device specially designed for method

Abstract

The invention relates to an ingot cooling method and a water circulation cooling device, the water circulation cooling device comprises a cooling water tank, two back flow channels, a transfer water tank and a radiator, wherein the top of the cooling water tank is opened and the opening is used for soaking and cooling an ingot die on a conveying chain machine, and two side plates in the width direction of the cooling water tank are higher than the bottom surface of a die with an upward ingot groove opening and drainage openings are formed between two side plates in the length direction and thebottom surface of the die with the upward ingot groove opening respectively; the two back flow channels are correspondingly mounted on one sides of the drainage openings respectively and connected with the drainage openings on the same sides; the transfer water tank is connected with the outlet ends of the back flow channels; the water inlet of the radiator is communicated with the transfer watertank by a first water pipe and a variable frequency pump is mounted on the first water pipe, the water outlet of the radiator is communicated with a cooling tank by a second water pipe, and an ingotting die after casting is soaked under the liquid level in a below cooling water tank in the processing of horizontal running of the conveying chain machine. According to the ingot cooling method and the water circulation cooling device specially designed for the method, the conveying chain machine is arranged horizontally and doesn't need a drop, water circulation is realized, the cooling water inthe cooling water tank is dynamic, and the cooling effect is excellent.

Description

technical field [0001] The invention relates to the technical field of ingot cooling, in particular to an ingot cooling method and a water circulation cooling device specially designed for the method. Background technique [0002] The working principle of the continuous casting machine: the molten metal is released from the outlet of the mixing furnace, injected into the ship-shaped chute of the horizontal continuous casting machine through the chute, and then injected into the ingot mold through the distributor to form. After cooling with water, it is demolded and sent to a cooling conveyor for direct water cooling. The finished ingots are finally bundled and packaged. [0003] The existing indirect water cooling method refers to a zinc alloy ingot casting circulating water cooling assembly line disclosed in Chinese Patent Publication (CN206169208U), including a frame, and the frame is provided with a conveyor for circulating the zinc alloy ingot forming mold. The side of ...

Problems solved by technology

[0004] 1. Use a constant pressure pump to control the water pressure, and spray it to the back of the mold for cooling through the nozzle. The disadvantage is that the cooling point is uneven, and the water splashes. It will splash on the chain of the assembly line to wash off part of the lubricating oil, and the lubricating oil will be discharged to the circulation. Sink, these oils need to be filtered out regularly;

[0005] 2. When using nozzles, the nozzles with a diameter of 1.5mm are often blocked and need to be cleaned every two months, which consumes labor and affects production;

[0006] 3. It takes a long time for the mold to cool from 400 degrees to about 150 degrees, about 10 minutes

However, this structure is used for direct water cooling in the later stage, and requires a drop in the mold to achieve cooling. In this way, a relatively long design is required when making an assembly line, and the height must be relatively high to achieve it. The cost of an assembly line with the same functional material high, large footprint
