In this way, the piston (498) sensor port group (400) and especially sensor head (484) from slag or metallurgical furnace It protects against damage caused by other environmental conditions within (100 / 200). Figure 5 shows a method for operating a sensor in a metallurgical furnace (500) 30 Figures 6A-6D show various during the operation of the method (500) in Figure 5. 14 It shows the sensor port group located in the locations. Method (500) with operation 510. The process begins at this stage, where the material to be melted is placed inside a metallurgical furnace. is being loaded. The material is being melted and brought into a molten state. electrodes, gas burners or other techniques for heating the material It is used. Obtaining a molten material suitable for the production of a specified alloy. 5 In order to achieve this, a recipe is followed for mixing specific quantities and types of materials. This can be done. During the process, the furnace may be tilted or the molten material may expand its internal volume. It can make contact with a hot plate belonging to the surrounding side wall in another way. Slag is a byproduct of smelting ores and recycled metals. It is a byproduct. Slag of varying thicknesses forms on the hot plate, and the aforementioned 10 It can protect the hot plate against high furnace temperatures. Furnace operation. during this process, safety and proper recipe requirements are ensured while the molten material is being formed. In order to ensure that it is being monitored, it is desirable to perceive the conditions of the bakery. That's the situation. In process 520, a piston belonging to a cleaning group passes through a hole in the side wall of the furnace 15 From a largely aligned position (as shown in Figure 2A), sideways It extends through the hole in the wall and into the interior of the furnace (Figure 6B). (as shown). The cleaning assembly includes a clamping arm and a piston. A connecting rod is attached to an actuator in such a way that it can move. For example, The clamping arm can be connected to a pneumatic cylinder at one end. The clamping arm has 20 at the other end. It is securely attached to a small piston. The small piston is in contact with the outer surface of the hot plate. It is aligned. The piston, from its position aligned with the hot plate, is metallurgical. The heat is generated by moving the heat inwards towards the interior of the furnace. During the operation of the furnace, the heat... Slag forms along the outer surface of the plate and on the hole covered by the piston. Moving the piston inwards into the interior volume dislodges the slag and removes the aforementioned 25 It ensures that the slag is conveyed away from the hole. In process 530, the cleaning group moves back into the hole beyond a second pipe. is being drawn (as shown in Figure 2C). The second pipe draws fluid into the groove of the first pipe. It has a groove that connects in this style. An opening extending from the second pipe into the first pipe, It is located between the piston and the hole in the hot plate. The piston of the cleaning group is 30 the withdrawal, from the second pipe, the hole in the hot plate which has now been cleaned of slag. It provides access to the inside and from there to the interior of the oven. In Process 540, as shown in Figure 6D, a sensor is positioned outwards and sideways from the second pipe. It is extended into the first pipe, near the hole in the wall. This In this position, the sensor detects the conditions inside the oven's interior. Optionally, As shown in Figure 6D, the sensor extends outwards from the hole and into the interior volume of the furnace. It is extended. A sensor head is moved into the reservoir environment. 5 For this purpose, the sensor is connected to an actuator. In one example, the sensor is connected to a visible light. It is a camera. In another example, the sensor is an IR camera. In yet another example, the sensor It is in the form of a thermocouple or another heat sensing device. In process 550, the sensor detects a condition in the furnace. In one example, the sensor is used in metallurgical processes. While the oven is in operation, the internal operating temperature of the oven in question is 10 It can detect things like the presence of slag and the condition of bricks. In another example, the sensor can detect these things. It is able to visually perceive the internal conditions of a metallurgical furnace. In another example... The sensor is used to detect the presence of smoke or other gases. It is available for use. In process 560, the sensor travels the entire distance from the furnace outwards and into the second tube, 15 It is being retracted. This process positions the sensor head away from the first pipe. In order to protect the sensor after it leaves the hot interior volume of the metallurgical furnace, The second pipe is cooled using a spray cooling process to reduce the temperature. It can be cooled. In operation 570, the cleaning assembly is moved 20 degrees towards the position where it is aligned with the hole again. It extends. The piston is positioned flush with the outer surface of the hot plate. By moving it, the slag or molten material is directed into the first pipe or spray-cooled side pipe. This prevents entry into the interior volume of the wall. In one example, a metallurgical furnace is in operation. In this situation, a sensor is removed from the sensor group and replaced with a different sensor. It is being replaced. Different sensors can be of the same type. Alternatively, different sensors 25 It can be of a different type and different processes are used to obtain working or furnace data. It can be repeated. The above explanations are intended for the application of the current specification, however, Other and additional applications without going beyond the basic scope of the specification It is also possible to design it, and the scope of the specification includes the following requirements: 30 It is determined.
