Sintering Furnace solution

The thermal insulation time of sintering furnace is also an important parameter in brazing process. It is necessary for the solder to interact with the parent material and to form a strong soldering head. Extending the thermal insulation time can improve the strength of the sintering head, and it is possible that the performance of the joint will decrease seriously.

The sintering furnace solution is mainly based on the interaction between the solder and the parent material. When the solder material interacts with the parent material, the thermal insulation time should be reduced when the brittle tissue is increasing. However, when mutual diffusion effect of solder and is conducive to eliminate brittleness and low melting eutectic in the brazing seam, should be appropriately extended or extend the time of heat preservation, significantly diffusion processing to improve the performance of braze welding head.

The structure, size and number of sintering parts should also be considered. In order to ensure the overall uniformity of brazing parts to achieve the required sintering temperature, large and thick parts are longer than thin and small parts, and the quantity of the furnace is longer than that of the furnace.

The thermal insulation time and sintering temperature should not be isolated from each other. There is a certain compensation relationship between them, which can be complementary to a certain extent. The specific selection should be determined by experiment.
