Brake yi in the brake process due to dry friction and large friction, often appear overheating redness, at this time the staff often to the brake yb water to reduce the temperature.The brake is constantly rubbing against the heat, causing the surface temperature to rise.When its table and cherry red in colour, the local surface temperature can reach 800 ℃ above, can cause the change of organization structure and plastic deformation.Using tap water to reduce the temperature of the brake, the foot has been quenched, the surface topical hardness increases, the internal stress increases, the cold brittleness increases.Due to the effect of repeated of the tangential force at the same time, resulting in surface layer of blocky carbides and inclusions and local crack initiation, with irregular alternating shock, speed up the crack extension of the registry.CNC SLS SLA Vacumm casting tooling.
Brake yi of most organizations is in casting position, coarse grains, there are many dotted along the crack near the crack of inclusion particles, at the same time, near the crack and its grain size is very uneven, the tissue defects under the greatly reduced the strength of the material and xiang, easy cause stress concentration.The original heat treatment of the workpiece USES positive fire + medium frequency induction heating quenching and self-tempering.According to the analysis of the organization, there is a problem in the process of positive fire: the heating temperature and the time of heat preservation are not enough, and a considerable part of the cast structure is preserved.The temperature uniformity of the furnace is not uniform.Due to the large size of the brake, the heating of normal fire is carried out in the coal furnace, and the temperature uniformity is poor.In the original process, the insulation temperature is indicated (850~900), but the temperature indicated by the thermocouple is difficult, so the actual temperature is lower than the process requirement.Based on analysis of the brake yi crack is the main reason for the failure of normalizing temperature is not enough, most organizations still is in casting position, coarse grains, low intensity, workpiece and partial inclusion aggregation.In addition, the use condition of the workpiece is very bad, and there are frequent hot and cold phenomena, and the internal stress is large, which causes the workpiece to form the crack source from the inclusions and gradually expand the crack.CNC SLS SLA Vacumm casting tooling.
