Jiaxing bearing manufacturers marketing center: heat treatment process operation

Company marketing center of jiaxing jiaxing bearing bearing group sales co. , LTD. Is established in the spot sales center, specializing in HRB bearings, bearing applications of rich experience, today we are going to introduce the heat treatment process for everyone. Heat treatment process operation: ( 1) Attention should be paid to the location of the workpiece, ensure uniform heating, to prevent overheating. Use gas or natural gas furnace, be careful not to make the nozzle or the workpiece heating flame directly. （ 2) Axial and thin rod workpiece, should pay attention to the placement of artifacts, in case of deformation. （ 3) Completely annealing furnace charging, generally small and medium carbon steel and low alloy steel workpiece, can not control the heating rate, load has mounted directly to the annealing temperature of the furnace; Can also be low temperature furnace charging, along with the furnace heating up. For medium and high alloy or too big to complicated shape, low temperature furnace charging, segmentation, and control the heating speed is less than 100 ℃ / h. （ 4) Large workpiece to stress annealing, should be installed at low temperature furnace, slowly heat up, in case the result of the rapid heating thermal stress. （ 5) As far as possible when normalizing air cooling on flat ground; Regardless of the workpiece, when the air cooling will open in a dry air cooling, shall not be stacked or overlap, shall not be placed in the damp place or there is water, in order to ensure uniform cooling rate, uniform hardness. （ 6) The heating temperature of material is different, but the same workpiece can be in the same furnace heating. （ 7) Cross section workpiece of different size, at the same heating furnace, the small should be placed outside the furnace. （ 8) In general, the water temperature is not more than 40 ℃, the oil temperature does not exceed 80 ℃. 24-hour customer service hotline: if you are interested in the above introduction of jiaxing bearing or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: the company jiaxing bearing sourcing consultant LTD.
