The invention belongs to the technical field of refractory brick production, and particularly relates to a refractory brick detection conveying line and method.According to the refractory brick detection conveying line, a first sensor is arranged beside a first turnover mechanism, a second sensor is arranged beside a second turnover mechanism, and a third sensor is arranged beside the front end of a third conveyor; and a fourth sensor is arranged on the refractory brick detection device, according to the conveying position of the refractory brick, related sensors sense signals, a controller controls corresponding mechanisms to generate corresponding actions, and the detection conveying line for the refractory brick is high in automation degree. According to the refractory brick detection device of the refractory brick detection conveying line, the weighing device, the size detection device and the stamping assembly are integrated together, so that weighing, size measurement and stamping operation can be achieved at the same position, procedures are concentrated, the length of the refractory brick detection conveying line is shortened, the occupied area is reduced, and the detection efficiency is higher.
