Description

FIELD OF TECHNOLOGY

This invention relates to a method for determining the temperature distribution in a process. International Classification G01J.

BACKGROUND

Currently known is the use of sensors designed to periodically determine the parameters associated with temperature conditions that are related to the course of technological processes.

This invention proposes improvements for the possibility of optimizing temperature control at the stage of technological processes - "HEATING MODE", in which the distribution of operating temperatures is detected by means of computer-controlled diagnostic tests carried out by means of adjustable equipment connected to a protective structure with a shutter containing a pointer and a sensor radiation, which after identifying the parameters of the temperature conditions of the process ne they are transferred to a computer that processes, visualizes, and registers them in order to be able to control and regulate the distribution of operating temperatures during this process.

DESCRIPTION

The following description of the present invention is made with reference to the schematic images shown in the accompanying drawings as a non-restrictive example.

Figure 1 schematically depicts a protective structure with a shutter (3) located in a closed position.

Figure 2 schematically depicts a protective structure with a shutter (3) located in an open position.

It can be seen that inside the protective structure there is a pointer (5) and a radiation sensor (4), which, after measuring the temperature parameters of this process, transmit them to computer equipment (9), which processes them and registers them to be able to control and regulate the distribution of operating temperatures near the surface stamp walls (8).

Figure 2a schematically depicts the effect of a special fluid coolant (12), the purpose of which is to remove a small amount of heat from the die (8) to reduce the stage - "HEATING MODE".

Fig.2b schematically depicts the effect of the main fluid coolant (11), the purpose of which is to conduct the process properly.

In these drawings, each individual unit is indicated as follows:

1 - adjustable equipment, the diagnostic examination of which, programmed by a computer (9), is performed automatically;

2 - protective construction;

3 - shutter;

4 - radiation sensor designed to measure the temperature parameters of the observed process;

5 - pointer designed to transmit measurements;

6 - connecting cables of computer equipment;

7 - pneumatic connection for supplying air to the protective structure;

8 - stamp, the surface of which measures the distribution of operating temperatures;

9 - computer equipment;

10 - a device designed to introduce sprinklers between the halves of the stamp in each cycle;

11 - a sprinkler of a conventional fluid coolant based on ordinary water;

12 - a sprinkler of a special fluid coolant for the stage - "HEATING MODE".

The operation of this equipment is as follows:

AT CONTINUOUS IMPLEMENTATION OF THE TECHNOLOGICAL PROCESS

- management of a program of automated surveys carried out by regulated equipment (1);

- collection and processing of temperature parameters measured by the radiation sensor (4), and their conversion to temperature values;

- visualization and mapping of the distribution of temperature values on the surface of the stamp (8);

- control and regulation of the process to optimize the distribution of operating temperatures.

AT THE STAGE OF THE HEATING MODE

DETERMINATION of the parameters of the temperature regime of the stamp (8) through surveys performed using adjustable equipment (1) connected to a protective structure (2), which contains a pointer (5) and a radiation sensor (4).

TRANSFER of measured data to computer equipment (9), which processes, visualizes and registers them in the form of temperature values. These values are compared, in each cycle, with the given reference values to obtain signals that carry out control actions with feedback on the process flow.

Temporary REVERSE effect on the process using a special fluid coolant (12), which takes a small amount of heat from the die (8) at the HEATING MODE stage to reduce the required number of cycles to ensure the normal thermal operating mode for the die (8) and reduce the time single cycle of the given technological process.

SWITCHING, controlled by computer equipment (9), from a fluid coolant (12) to a fluid coolant (11) based on ordinary water by supplying another control signal after reaching the normal thermal operating mode.

The clarity of the drawings emphasizes the simplicity and reliability of this technique, which can be used for metallurgical applications with particular purpose, in particular in stamping and injection plants or in similar technological processes.

It should be noted the importance of the fact that the shutter (3), which opens only for measuring parameters, always protects the radiation sensor (4) and indicator (5) from the adverse environmental conditions inherent in the metallurgical process.

In addition, it should be noted that the resulting temperature map of this process allows you to have a summary overview of the current conditions of this process. It also allows you to simultaneously identify possible critical areas that require more attention when regulating the cooling system.

This invention can be performed with technological solutions, as well as structural ratios and sizes, which can satisfy various technical needs.

All methods described, demonstrated and claimed in this document for detecting the distribution of operating temperatures in technological processes are considered as part of the scope of legal protection of this invention.
