Embodiment 1

[0033] This embodiment provides a method for producing hot-rolled pickled plates, please refer to figure 1 , figure 1 It is a flow chart of the method for producing hot-rolled pickled plate in this embodiment, the method comprising:

[0034] Step S101, after the steel coil is hot-rolled, monitor the temperature of the steel coil when it cools down;

[0035] Step S102, when it is detected that the temperature of the steel coil drops to 50°C-120°C, start to pickle the steel coil.

[0036] The method for producing hot-rolled pickled plate provided by the application is described in detail below:

[0037] First, after steelmaking, the resulting coils are hot-rolled.

[0038] Specifically, in order to make the waste heat of the steel coil meet the requirement of heating the acid solution, the off-line temperature of the steel coil after hot rolling can be set at 500°C-800°C.

[0039] Next, step S101 is executed to monitor the temperature of the steel coil when it is cooled down...

Embodiment 2

[0072] In embodiment two, a pickling system for hot-rolled pickling plates is provided, please refer to figure 2 , figure 2 It is a schematic diagram of the system in this embodiment, and the system includes:

[0073] Pickling tank 201;

[0074] A thermometer 202, located at one end of the pickling tank 201, is used to monitor the temperature of the steel coil when it is cooled down after the steel coil is hot-rolled;

[0075] The controller 203 is connected with the temperature measuring instrument 202, and is used to control the steel coil when receiving the prompt signal sent by the temperature measuring instrument 202 indicating that the temperature of the steel coil has dropped to 50°C-120°C Move in the pickling tank 201 and pickle.

[0076] In a specific implementation process, the thermometer 202 may be an infrared thermometer or an electronic thermometer, which is not limited in this embodiment.

[0077] In the embodiment of the present application, the controlle...

Abstract

The invention discloses a hot-rolled pickled plate producing method and a hot-rolled pickled plate pickling system. The method comprises the steps of monitoring the temperature of a steel coil when the steel coil cools down after being hot-rolled, and pickling the steel coil when it is monitored that the temperature of the steel coil is reduced to 50-120 DEG C. The method is used for solving the technical problem of power consumption caused by heating of a steel coil before picking during hot-rolled pickled plate production according to the prior art, and energy saving is realized.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a method for producing hot-rolled pickled plates and a pickling system for hot-rolled pickled plates. Background technique [0002] With the promotion of low-carbon life, energy reduction and consumption reduction has become an important responsibility of all walks of life. Hot-rolled pickled steel plate is a green steel product that can replace cold-rolled steel products. It meets the requirements of energy reduction and consumption reduction. This product is widely used in Automobiles, home appliances, hardware and other fields have good market promotion prospects. [0003] But the current pickling plate production process steps are: steelmaking - hot rolling - cooling - heating - pickling, that is, after the steel coil is hot rolled, it will first cool the steel coil to room temperature, and then pickle the steel coil The coil is heated. [0004] That is to s...
