Steelmaking requires controlling the carbon content, eliminating harmful elements, retaining or increasing beneficial elements, and adjusting the ratio between elements to obtain the best performance. Sampling is to measure the temperature of molten steel and take samples before steelmaking, providing temperature and chemical composition parameters for steelmaking process control, which serves as an important basis for the process operation of the steelmaking process.
