When the plastic anti-collision protection safety helmet is forcibly opened, the plastic anti-collision protection safety helmet can be damaged and cannot be reused, the manual opening of the detection probe is difficult to a certain degree, and the illegal change of the detection probe is also avoided. The plastic anti-collision protective safety helmet has the main function of preventing the detection probe from being damaged due to direct rigid impact on the front surface of the detection probe in the process of throwing and falling the detection probe and the transportation process. In the using process, the metal detecting head can carry a plastic anti-collision protective safety cap to pass through the probe protective tube together, and the free falling body directly falls into the high-temperature molten steel being smelted from the height of 13-20 meters for detection. In the throwing and falling process, the metal detecting head can be accidentally contacted with a rigid object, if no protection device is used for the collision, the metal detecting head can be accidentally damaged, and the plastic anti-collision protection safety helmet effectively avoids the damage problem caused by the accidental collision. In addition, when the metal probe enters the smelting converter, the metal probe passes through a high-temperature solid dust environment with the temperature of about 150 plus 700 ℃ in a very short time (the metal probe freely falls after passing through the probe protection tube after accelerating to a certain speed and is about 0.6-0.8 second in a high-temperature environment) and then enters a molten steel environment with the temperature of about 1500 plus 1600 ℃, the high-temperature resistance of the plastic anti-collision protection safety cap can ensure that the plastic anti-collision protection safety cap is almost completely stored when passing through a low-temperature region, and the plastic anti-collision protection safety cap is instantly dissolved and shrunk when contacting the high-temperature molten steel with 1600 ℃, so that the molten steel is rapidly contacted with the oxygen half cell of the metal probe and the temperature thermocouple, and the possibility that the cold steel is coated with slag by hot molten steel when passing through a molten steel layer is. In the in-service use process, the utility model discloses a test probe's detection reflection speed improves 0.8 seconds from 1.3 seconds, and this item improves to being detected the shortening of molten steel and test probe contact time, also has obvious promotion.
Sixth, the utility model discloses an add high temperature resistant breather valve in the metal detecting head, atmospheric pressure stability and constant temperature stability under the high temperature of the subassembly of can controlling effectively improve the detection stability of metal detecting head. The high-temperature-resistant vent valve is placed at one end of the metal probe in a plugging mode. Because the internal of the metal probe head is at the ambient temperature in the early detection stage, the annual average temperature is between 22 and 35 ℃, when the metal probe head enters high-temperature molten steel at 1600 ℃ under the condition that the internal temperature and the air pressure are not changed, the temperature drop of the air in the metal probe head is sharply improved, and meanwhile, a temperature thermocouple in the metal probe head is influenced to a certain extent. Through adding high temperature resistant breather valve, obstructed high temperature molten steel to the inside air temperature's of metal detector influence. The utility model discloses an effect at this high temperature resistant breather valve of mode test of metal detector head internally mounted temperature sensor, its detected data is: after a metal probe without a high-temperature-resistant vent valve enters molten steel, the constant temperature time of the internal temperature of the metal probe is averagely 10.7 seconds, and the average temperature rise is about 26 ℃; after a high-temperature-resistant vent valve is added into a metal probe, the constant temperature time is averagely 16.5 seconds, and the average temperature rise is about 15 ℃. Therefore, the improvement not only improves the constant temperature time in the metal detecting head, but also reduces the temperature rise effect in the metal detecting head, and plays a role in heat preservation and constant temperature of the metal detecting head in a high-temperature environment.
Seventh, the utility model discloses cut the guiding gutter on the outer wall of metal detecting head, can avoid too big impact when letting the metal detecting head get into the molten steel.
