Q295GNH atmospheric corrosion resisting steel, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
