Reducing fuel consumption, reducing emissions and improving the safety performance of automobiles are currently the focus of the automotive industry. Therefore, the performance of automotive steel plates is also very challenging. The use of hot-formed "stamp-hardened" steel plates can reduce body weight and improve body safety. Properties, improve stamping formability, control springback, improve dimensional accuracy of parts, improve weldability, corrosion resistance, etc.
Automotive steel sheet hot forming mainly includes heating, stamping and quenching. First of all, the raw steel plate needs to be heated to the austenite region. At this stage, it is easy to overheat or overfire, which will cause the strength and impact toughness of the steel plate to be reduced. In order to avoid excessive loss of cost, we can install a thermal imaging system to monitor the temperature distribution in the furnace online in real time, and use a thermal imager with point, line, and frame temperature measurement functions to collect the temperature distribution field of the entire component. Resolution, and cross positioning function in high temperature places, real-time transmission of the thermal image of the temperature field to the client terminal, the brighter areas on the thermal image indicate high temperatures, the white areas are high, the black areas are low local. Based on the information received by the computer, the staff judges whether the part has reached the appropriate standard for entering the mold.
In the hot stamping and quenching steps, it is necessary to maintain the pressure to cool to 100-200 ° C at a cooling rate greater than 27 ° C / s. The infrared thermal imaging system can detect the temperature change of the steel components in the quenching pool, ensure the cooling speed of the steel components, and grasp the The temperature of the mold and the heat map data collected by the thermal imager are transmitted to a computer for analysis.
