Mesh belt furnace operation points
The mesh belt furnace is one of the main products of our company, and our products are of good quality. Here are some key points for the operation of the mesh belt furnace:
1. Cleaning is very important. The oil and gas brought in the unwashed workpiece has obvious influence on the atmosphere in the furnace. The CH4 (methane) and CO2 (carbon dioxide) are relatively high, and the CO (carbon monoxide) is low, which is easy to produce a large amount of carbon black.
2, the thickness of the heating zone heating temperature fluctuation range should not be greater than 20-30 ° C, please note that the temperature drop of a zone should not be greater than the set temperature of 50-60 ° C, more than the thinner should be added, in principle, M8, M10, M12 is not more than the thickness of the part. The heating thickness of the large amount is not more than 40mm, and the heating should be avoided. If the heating is small, pay attention to stacking one piece, do not spread it, otherwise it will cause overheating and overheating.
3, promptly remove the dirt inside the cleaning box, adjust the mesh belt offset to develop habits.
4. Heat treatment energy consumption accounts for 35%-45% of the heat treatment process cost. Energy conservation is a work that has to be invested in the heat treatment process. On the one hand, early planning, production as much as possible to do the same variety; on the other hand to avoid rework, improve product qualification rate, self-test should be timely, accurate, reduce error rate.
5. Considering that the raw material may have a decarburization layer, the carbon potential is set at 0.36%-0.45%, the upper limit is used for decarburization, and the lower limit for non-decarburization is used to reduce the consumption cost.
