When the billet is produced, marks such as production date, materials, batch numbers and the like need to be marked on the end surface of the billet, and in the whole marking process, the spray gun is very close to the end surface of the billet and needs to be continuously subjected to relative displacement with the end surface of the billet. However, when the continuously cast steel billet is cut by the flame cutting machine after being measured by the sizing equipment, the continuous cast steel billet is influenced by the temperature of cutting flame and the cutting speed, the end surface of the steel billet often has the phenomena of unevenness, built-up edge and the like, and even has the end surface with larger inclination (generally less than 3 degrees) in serious cases, so the spray gun is easy to collide with the end surface of the steel billet in the axial direction and the lateral direction. Therefore, in order to protect the relatively weak spray gun marking mechanism, reduce the damage possibly suffered in the using process to the maximum extent and ensure the normal operation of the marking, the side protection device of the spray gun marking mechanism is provided. The axial protection for the spray gun identification means is not described here.
