Description

Technical Field

[0001] The utility model belongs to the field of steelmaking equipment, and more specifically relates to a quenching device for steelmaking in a steelmaking plant. Background Art

[0002] The quenching of steel is a process of heating the steel to a critical temperature and keeping it warm for a period of time to make it austenite, and then cooling it rapidly at a cooling rate greater than the critical cooling rate to undergo martensitic transformation. The solid solution treatment of aluminum alloys, copper alloys, titanium alloys and other materials or the heat treatment process with a rapid cooling process is usually called quenching. Quenching can improve the hardness and wear resistance of metal workpieces.

[0003] In steel mills, quenching devices are often used to quench parts after heating. After quenching, there is often a large amount of residue in the placement frame. Since the residue is inside the placement frame, it is not convenient to clean; and a large amount of residue will also be stored at the bottom of the quenching device after long-term use. If the waste water is discharged directly, it will cause blockage in the discharge pipe and affect normal use. Utility Model Content

When the workpiece to be quenched is placed in the workpiece placement structure, the slider can move downward, so that the placement frame is immersed in the coolant, and the coolant will enter the placement frame from the water inlet, thereby quenching the workpiece. Since the workpiece placement structure is composed of a connecting frame and a placement frame, the placement frame can be removed from the connecting frame after the quenching treatment is completed, which is convenient for cleaning the placement frame; in addition, a filter is also provided in the middle of the water tank. When the workpiece is quenched, the generated residue will be filtered through the filter to prevent the residue from gathering in the drain pipe and causing blockage of the drain pipe. A moving block is also provided on the filter. After the quenching device has been running for a period of time, the residue can be pushed into the collection box by the moving block, and then the residue can be discharged through the discharge pipe.

When the placement frame is immersed in the water tank, the coolant can enter the placement frame through the water inlet hole, so that the workpiece can be quenched. When the placement frame is raised from the water tank, the coolant flows out from the water inlet hole, and then the placement frame is removed from the connecting frame, and the placement frame body is separated from the load-bearing plate, the workpiece can be taken away, and the placement frame is removed from the connecting frame, which can be easily cleaned to avoid clogging of the water inlet hole.

[0047] Optionally, an electric push rod is provided on the side wall of the water tank, an output end of the electric push rod extends to the inside of the water tank and is connected to a moving block, and a brush is provided between the moving block and the filter.

[0048] Specifically, a collecting box is protruding on one side of the water tank, and an electric push rod is provided on the other side. The output end of the electric push rod passes through the side wall of the water tank and is connected to the moving block. When the quenching device has been running for a period of time, the electric push rod can be started to drive the moving block to move horizontally on the filter screen, so that the brush can push the residue on the filter screen into the collecting box, and then the electric push rod drives the moving block to reset.
