Embodiment 1

[0151] Embodiment 1: The initial state is the case where all resources are in an idle state

[0152] Figure 10 An example of a resource allocation plan for 3 stacks of steel coils to be processed, 3 hearths, 2 heating mantles, 1 cooling mantle, and 1 crane is given. After seeing the description of the following embodiments, it will be no problem for those skilled in the art to generalize to any number of steel coil stacks, hearths, heating mantles and cranes.

[0153] Step 1: When the steel coil stack information to be processed reaches the site, run the data collector 1 to collect real-time steel coil stacks and the occupancy of resources such as the hearth, heating mantle, cooling mantle, and crane in the bell-type furnace workshop, and transmit the collected information to to data processor 2;

[0154] The second step: according to the actual production situation, the input information can be analyzed in depth according to the data processor 2, and the processing time of...

Embodiment 2

[0177] Example 2: The initial state is the case where there is no idle stove available

[0178] When the steel coils to be processed are annealed, since there is no idle furnace base available, there is no idle furnace base available during the furnace loading stage. At this time, the steel coil needs to enter the stage of waiting for the furnace base. In order to shorten this waiting time, the resource allocation plan generator selects the earliest released furnace base allocation Stack the steel coils to meet the annealing requirements of the steel coils. , if multiple hearths are released at the same time, they will be allocated according to the principle of proximity, and if there is a situation where steel coil stacks compete for resources, they will be allocated in the order of steel coil stacks. Its specific implementation is the same as that of Example 1, and will not be repeated here.

Embodiment 3

[0179] Example 3: The initial state is the situation where no idle heating mantle is available

[0180] Since there is no idle heating mantle available, when the steel coil stack enters the heating mantle deduction stage, there may be no idle heating mantle available. At this time, the steel coil stack enters the waiting heating mantle stage, and the resource allocation plan generator selects the earliest released heating mantle Assigned to the steel coil stack to meet the requirements of steel coil annealing. If multiple heating mantles are released at the same time, they will be distributed according to the principle of proximity. In the event of steel coil stacks vying for resources, they will be allocated in the order of steel coil stacks. Its specific implementation is the same as that of Example 1, and will not be repeated here.

Abstract

The invention discloses a control method and a control device for improving the operating efficiency of material handling equipment of bell type furnace units of steel enterprises, which are mainly realized by a data acquisition device 1, a data processor 2, a control proposal generator 3, a production process simulator 4 and a control information uploader 5 through a network (TCP / IP) 6. The data processor is used for performing deep-level analysis and processing on acquired information, and inputting and transferring into the control proposal generator; a crane control proposal generator comprises two modules, namely a resource allocation proposal generator 9 and a crane operation proposal regulator 10, the resource allocation proposal generator allocates limited resources of a bell type furnace workshop, and the crane operation proposal regulator performs concrete execution on a resource allocation result and can perform further regulation on the allocation of the resources; the production process simulator simulates the operating environment of the bell type furnace production workshop, performs dynamic simulation on the production flow of a bell type furnace and the operation of a crane, and displays the dynamic simulation through an LED display 8; and the control information uploader is used for uploading control information produced by the crane control proposal generator to a crane control terminal 7 of the bell type furnace workshop and guiding the production of the bell type furnace workshop.

Description

technical field [0001] The invention belongs to the field of metallurgical information technology, relates to automation technology, and in particular provides a method and a device for improving the operation efficiency of the logistics equipment of bell-type furnace units in iron and steel enterprises, which are used to control the operation of the logistics equipment in bell-type furnace workshops. Background technique [0002] Bell furnace annealing is a necessary process for deep processing of coils through cold rolling process. It has a very significant effect on improving the tensile strength, yield strength and internal mechanical properties of steel coils. The short-term annealing process of the bell furnace is shown in Table 1, including furnace loading, closing the inner cover, sealing, pre-purging, closing the heating cover, heating, removing the heat cover, closing the cooling cover, cooling, removing the cooling cover, removing the inner cover, Unload volumes a...
