Detailed ways

In order to facilitate a further understanding of the implementation method and the achieved effects of the present invention, preferred embodiments are described in detail below in conjunction with the accompanying drawings.

The top of the bell-less tank furnace is divided into the upper tank (receiving tank) and the lower tank (weighing tank). The system under the trough transports the charge to the feeding tank through the main belt. When the lower feeding tank meets the charging conditions, the upper gate in the feeding tank is opened, and the furnace charge is loaded from the upper feeding tank to the lower feeding tank. At this time, the charge is waiting for the feed line in the feed tank. During the waiting process, the feed tank needs to be punched. After reaching the feed line, the lower gate in the feed tank is opened, and the charge is set according to the angle and time that have been set. It is thrown into the blast furnace by the distributor, thus completing a distributing process. In this process, one or more software trackers are established for the loading tank and the unloading tank respectively, that is, the software tracker for the loading tank and the software tracker for the unloading tank. The state of pressure release and so on is tracked.

When the under-trough system discharges materials to the top of the blast furnace, the under-trough system will automatically generate an under-trough software tracker for the material batch. This tracker is calculated and generated by the under-trough system software and can track the current position of the material batch in real time. When the material batch arrives at the top of the furnace, the top system of the furnace will receive the arrival signal of the head of the material sent by the system under the tank, and then the top system of the furnace will start the software tracker of the loading tank.

The software tracker in the present invention includes a time detection module, a parameter setting module, a time comparison module, an alarm module and an equipment optimization module. The time detection module is used to detect the start and end moments of each process flow of the top of the tank furnace without material bells to determine the time length of each process flow, set the reference time of each process flow according to the parameter setting module, and compare each process through the time comparison module The actual time length of the process is compared with the set reference time. When the actual time length of the process exceeds the set reference time, the alarm module sends an alarm signal, and at the same time starts the equipment optimization module to optimize the equipment so that each process The time length of the process is controlled within the set reference time, so as to improve the charging and discharging efficiency of the top of the bell-less tank furnace.

As shown in Figure 1, the time detection module of the loading tank software tracker detects: 1 is the moment when the material batch reaches the furnace top; 2 is the moment when the material batch completely enters the furnace roof; 3 is the moment when the upper gate starts to open ; 4 is the moment when the upper gate is fully opened; 5 is the moment when the feeding gate is started to be closed; 6 is the moment when the feeding gate is completely closed and the feeding tank tracker is ended.

From the loading tank software tracker, you can clearly understand the situation of this batch of materials in the feeding tank, including the following 5 time periods:

Tsl is the length of time for this batch of materials to enter the feeding tank, and the length of this time mainly depends on the opening of the system gate under the tank, the way of discharging materials and the width of the belt;

Tsw is the length of time the batch of materials is stored in the loading tank. When the lower tank is not ready for loading, the batch sent by the system under the tank will be stored in the loading tank first. Once the lower tank is ready for loading After the material condition, the material batch will be transferred from the upper tank to the lower tank;

Tso is the length of time to open the upper gate, the length of this time mainly depends on the pressure of the hydraulic system and the working conditions of the valve equipment;

Tsz is the length of time for loading materials from the upper material tank to the lower material tank, and the length of this time depends on the type, weight and diameter of the upper gate of the material batch;

Tsc is the length of time to close the upper gate, the length of this time mainly depends on the pressure of the hydraulic system and the working conditions of the valve equipment;

After the loading tank software tracker is started, these times will be recorded respectively, clearly showing the current state of the batch. The time period of each technological process can also be set as a reference time by the parameter setting module according to the production experience, start the time comparison module, once the time period exceeds the set reference time, start the alarm module of the feeding tank software tracker , the system automatically gives an alarm on the screen, prompting that there is a problem in the loading process. For example, if a time ts is set for Tsz, but the actual time for filling the feeding tank is greater than ts, it means that there is a problem in the process, and it may be that the upper gate is jammed. At this time, the system will alarm and start the upper gate. The equipment optimization module of the tank software tracker processes the upper gate.

It can also be seen from the feed tank tracker that when Tsw=0, the timing process can be optimized as shown in FIG. 2 . While charging the material tank, considering the opening time of the upper gate, the upper gate can be opened in advance, thus reducing the charging time of the furnace top system.

When the upper gate is fully closed, the furnace roof system will start the software tracker for the unloading tank.

As shown in Figure 3, the time detection module of the unloading tank software tracker detects: 1' is the moment when the upper gate is completely closed; 2' is the moment when the punching of the unloading tank is completed; 3' is when the probe reaches the material line 4' is the moment when the lower gate starts to open; 5' is the moment when the lower gate is fully opened; 6' is the moment when the lower gate is closed; 7' is the moment when the lower gate is completely closed; The moment the pressure is over.

Txp is the stamping time length of this batch, and the length of this time mainly depends on the stamping method adopted by the furnace top system and the pressure of the stamping gas;

Txw is the length of time that this batch of materials is stored in the batch tank, and the length of this time mainly depends on the furnace conditions of the blast furnace system;

Txt is the length of time for the probe to lift the ruler. The length of this time mainly depends on the setting of the material line and the speed of the ruler;

Txo is the length of time to open the lower gate, the length of this time mainly depends on the pressure of the hydraulic system and the working conditions of the valve equipment;

Txb is the length of time for fabricating this batch of materials, and the length of this time mainly depends on the setting method of the fabric matrix of this batch of materials;

Txc is the length of time to close the lower gate, the length of this time mainly depends on the pressure of the hydraulic system and the working conditions of the valve equipment;

Txf is the length of time for pressure relief, and the length of this time mainly depends on the pressure on the top of the furnace.

After the unloading tank software tracker is started, these times will be recorded separately, clearly showing the current state of the batch. Similarly, the time period of each process program can be set as a reference time by the parameter setting module according to the production experience. Once the length of the time period exceeds the set reference time, start the alarm module of the unloading tank software tracker, and the system will automatically display on the screen An alarm is given on the screen, indicating that there is a problem in the loading or distributing process. At this time, the equipment optimization module of the unloading tank software tracker is started to deal with the corresponding equipment.

Through the establishment of the charging software tracker on the top of the tank furnace without charging clocks, the specific situation of the batch can be clearly understood, the alarm status can be given in time, and the action sequence can be optimized. The software tracker of the loading tank and the unloading tank can cooperate with the software tracker of the tank, so that the number of main belt stops can be reduced, the feeding rhythm can be faster, and the feeding capacity can be improved.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
