Description LAG-S100 Ladle Slag Detection System (Eddy Current) Overview The continuous casting ladle slag detection device is used to detect the slag content of the ladle nozzle in the steelmaking continuous casting process, so as to improve the cleanliness of the tundish molten steel and obtain the best yield of the ladle molten steel. The device adopts the principle of electromagnetic induction detection. The meaning of slag detection To achieve high output: In order to ensure the cleanliness of molten steel in the ladle, if we detect slag by eyes, we often close the ladle prematurely, so that it will reduce the yield of molten steel. However, if we use slag detection system, we can detect slag accurately and timely, so that the amount of residual steel is controlled at 1%-2% to achieve high output. Improve the cleanliness of molten steel: The steelmaking slag gets into the tundish is the main reason that affects the cleanliness of finished steel. The use of the slag detection system can reduce the amount of steelmaking slag carried into the tundish to a very small amount, and can also reduce the defects on the slab surface at least 80%. Avoid blockage of the nozzle: The steelmaking slag gets into the tundish is also the main reason for the blockage of the nozzle due to secondary oxidation. After using the slag detection system, the blockage of the nozzle can be greatly reduced. The composition of the system The slag detection system mainly consists of five parts: sensor, preamplifier, signal processing unit, central processing unit and platform control box. System control flow chart The working principle of the sensor The sensor adopts the principle of electromagnetic induction for signal detection, and its typical structure is two concentric coils. When the primary coil is supplied with an intermediate frequency excitation current, due to the action of the magnetic field, an eddy current is generated in the steel flow

Description ZSQ-T100 Online Surface Quality Inspection System for Casting Billet (Eddy Current) The principle of the system The ZSQ-T100 online surface quality inspection system for casting billet adopts the principle of eddy current non-destructive testing. According to the section of the continuous casting machine and the shape of the casting billet, the eddy current sensors of different structures can be used to realize the non-contact surface defect detection on the surface of the billet, and draws the surface defect graph of the billet in real time according to the detection results. The composition of the system Detection frame: The detection frame is used to support the central detection sensor. The height of the detection frame can be adjusted automatically by the motor, so that the central detection sensor is aligned with the casting billet to be inspected. Front and rear vertical nip roll device: The front and rear vertical nip rolls are used to make the inspected billet pass through the central detection head at an even and stable speed. The pressure roller is double pushed by the cylinder and the spring. Central testing host: The central testing host is placed on the testing table. It has a four-sided control disc that scans the surface of each casting billet. Descaling device: It is used to remove the oxide scale on the surface of the casting billet and eliminate the influence of noise on the eddy current flaw detection. System console: used to control the equipment and the entire testing process, control the mechanical actions of each unit and adjust the instrument parameters. It can realize automatic flaw detection online detection. Sensors: Slabs generally use eddy current sensor arrays to test the surface quality of the casting billet. Square billets, round billets and shaped billets generally use through-type eddy current probes to test the surface quality of the casting billets.

Description We all know by elevator that there will be self-contained air conditioners above the elevators. So, have you ever understood the air conditioners above the elevators, how does it work, and what are the advantages and disadvantages? Let's take a look at how to choose elevator air conditioners with the Escalator Company. First, the type of elevator air conditioner According to the environment of returning the wind, it can be divided into a car top air conditioning system and an external unit (hoistway) air supply air conditioning system. Car top air conditioning system: The air conditioner main unit is directly placed or suspended on the top beam of the elevator car. The air conditioner extracts the air in the car and sends it back to the car after cooling (heating), and then re-starts to adjust the car. The purpose of the internal temperature. External unit (hoistway) air supply and air conditioning system: air conditioning unit is installed outside the elevator shaft or through the central air conditioning system of the building, the treated air is sent into the elevator shaft by the air supply duct, and then the fan at the top of the car is sent into the sedan. The box realizes the adjustment of the air temperature in the car. Second, the advantages and disadvantages of each air conditioning system (1) Advantages and disadvantages of the car roof air conditioning system Advantages: mature technology, rapid cooling, saving energy consumption; Disadvantages: Increase the weight of the elevator car, installation and maintenance is more complicated than other methods, there is condensed water phenomenon. (2) External unit (hoistway) air supply and air conditioning system Advantages: simple structure, convenient installation and maintenance, no condensation. Disadvantages: increase the number of duct outlets, increase investment, and high energy consumption. The elevators may cause abnormal fluctuations in wind pressure of the central air-conditioning system under high-speed operation. Third, the elevator air conditioning system selection: The car top air conditioning system is the preferred air conditioning system because of its mature technology and low investment. In the market, most projects use a car-top air conditioning system. In addition, for the problem of condensed water, the current air conditioner for car topping has been treated by multiple atomization evaporation of condensed water to achieve a non-drainage target, thus solving the problem of condensed water. Fourth, the setting of the air conditioning air outlet in the car The arrangement of the air outlet and return air inlet in the car is mainly considered from the aspects of avoiding the generation of condensed water and avoiding the formation of small airflow in the ceiling of the car. In order to avoid the generation of condensed water, generally use wood or plastic material outlet, it will not accumulate condensation water; in order to avoid the formation of small air circulation in the car roof, affecting the cooling effect, can increase the between the air outlet and the return air inlet The plane distance is generally greater than 500mm, and the air outlet is not allowed to be placed in the inner space of the ceiling. information about Escalator Company: https://www.fujihd.net/
