Wear-resistant ceramic pipe in the quenching heat treatment, it is easy because of improper operational control, affecting the performance of the pipe itself, the quality of the face damage. Then what are the problems that often occur in the quenching of wear-resistant ceramic pipe?
1.Quenching and cooling process because of the low speed, easy to cause wear-resistant ceramic pipe hardness is not enough, hardness is uneven and other issues, quenching hardness is often in the high temperature stage of the cold speed is not enough to cause, so speed up the quenching medium used in the low-temperature cooling speed.
2. Wear-resistant ceramic pipe hardness in the heart after quenching is too high, this kind of problem may be too fast with the selected medium cold speed or medium of low temperature cooling rate is too high. One of the solutions is to change the quenching oil to meet the requirements. Approach two is to contact with the quenching medium manufacturer, targeted at adding appropriate additives to slow down the quenching oil in the low-temperature cooling rate. Approach three is to change the use of low hardenability steel.
3. Quenching deformation. Can be accelerated by accelerating the cooling rate and try to achieve uniform cooling, application as long as the reasonable choice of the same direction of action plus the measures. Can solve most of the wear-resistant ceramic pipe processing plant quenching deformation problem.
