The invention discloses a full-automatic production system for refractory bricks. The system is sequentially provided with automatic weighing and distributing devices, pressing machines, brick receiving and conveying tables, detecting machines, a defective product conveying table, a brick taking and stacking device and kiln car positioning areas according to refractory brick forming procedures. According to the system, raw materials are automatically detected and screened after being pressed and formed through the automatic weighing and distributing devices and the pressing machines, the bad bricks are automatically removed, the qualified bricks are stacked and loaded into a kiln car through the brick taking and stacking device, and finally, the kiln car full of the qualified bricks is fedinto a kiln through an intelligent control system for firing, and the finished bricks are obtained; and the full-automatic operation is achieved, the defects that refractory brick manufacturing in the prior art is low in automation degree, low in manufacturing efficiency and the like are overcome, and therefore, the labor cost is reduced, the working efficiency is improved, and meanwhile, the safety risk is greatly reduced, the life safety of people is guaranteed, the influence of dust on the health of people in the brick pressing process is reduced, the labor intensity is reduced, and the problem of difficulty in recruiting workers is solved.
