Abstract

The invention provides an operation control method for producing passivated products, comprising: obtaining the order requirements for steel strips, the order requirements include passivation required and no passivation required; obtaining the process flow according to the order requirements; According to the process flow, the production parameter information is obtained; according to the order requirements and the production parameter information, the control parameter values ​​are matched and set; according to the order requirements and the control parameter values, the passivation roller coater is controlled Carry out the corresponding operations of automatic closing and opening. The invention solves the technical problem that manual control passivation is adopted in the prior art, and there is a parameter setting error, or the passivation is not passivated, and the passivation should not be passivated, which seriously affects the quality of the strip steel. Through remote control of the automatic shutdown and automatic opening of the passivation roller coater, remote automatic adjustment, automatic passivation control, avoiding mistakes caused by manual participation, ensuring the accuracy of parameters, and ensuring the technical effect required by passivation products.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing passivation, in particular to an operation control method for producing passivated products. Background technique [0002] Passivating the surface of the strip steel is an important production process of the hot-dip galvanizing production line. If the parameters are used improperly or the control is unstable during the production process, the passivation quality of the product will be affected, and finally the corrosion resistance of the strip steel surface will be affected. The appearance quality is also not conducive to the long-term use and maintenance of the equipment body, which increases the cost of personnel and equipment. In the production process of the prior art, the adjustment of passivation control parameters, input and shutdown, and switchover of passivation solution are completely controlled by the attention of personnel. Once the parameters are set incorrectly, or the pa...
