Embodiment 1

[0037] In the high-efficiency quenching plate quenching process of the present invention, all employees participate in the production rhythm control, and water pump workers are included in the production rhythm control. When producing steel plates with a thickness ≥ 40mm, the water replenishment valve is opened 8-10 minutes in advance, so that the production of new water is replenished in advance, 5 in advance Turn on two water tower pumps and one high-pressure pump in minutes.

[0038] The opening and closing of the lifting pump is controlled manually according to the liquid level display of the regulating pool and the suction well. When the water level of the regulating pool is lower than 3.5 meters, the lifting pump must be closed; When the water level is below 5.5 meters, one lift pump is turned on; when the water level of the regulating pool is above 5.5 meters and the water level of the suction well is below 5.5 meters, two lift pumps are turned on.

[0039] The adjustme...

Embodiment 2

[0051] When producing steel plates with a thickness less than 40mm, the water supply valve should be opened 3-5 minutes in advance, and one water tower pump and two high-pressure pumps should be opened 5 minutes in advance.

[0052] Other steps are with embodiment 1.

Abstract

The process of the invention relates to the technical field of production of quenching plates in heat treatment furnaces, and is a new process for rapid quenching of quenching plates, which can ensure that the flatness of the plate meets the process requirements, and realizes high-efficiency and continuous quenching. All employees participate in the production rhythm control, and the water pump workers are included in the production rhythm control. The water pump workers determine the number and time of opening the pumps in advance according to the production plan, and increase the adjustment speed by changing the step opening of the valve motor to meet the production needs. Key equipment adjustments In order to best adapt to the production rhythm mode and give full play to the potential of the equipment. It fully complies with the heat treatment and quenching process, can realize high-efficiency quenching production, meets the process requirements, shortens the quenching time and quenching water consumption, and improves the production rhythm and heat treatment furnace output.

Description

technical field [0001] The process of the invention relates to the technical field of production of quenching plates in heat treatment furnaces, and is a new process for rapid quenching of quenching plates, which can ensure that the flatness of the plate meets the process requirements, and realizes high-efficiency and continuous quenching. Background technique [0002] In the production of quenching plate, the water supply status of the water tower and the adjustment time of the quenching process valve of the quenching machine are closely related to the production of the quenching plate. production, invented the highly efficient, quenching process. [0003] In the current quenching process, the water pump team does not participate in the production control, and the production rhythm control is all completed by the quenching furnace operator. 8-10 minutes before the production of the quenching furnace, the quenching furnace production worker informs the water pump worker in a...
