U-bolt, also known as U-shaped card, is a kind of bolt commonly used in pipeline installation, mainly used to fix pipelines. In order to meet the needs of the work, U-bolts need to be heated and heat-treated. U-bolt heating is usually carried out by medium frequency induction heating power supply, and the effect is very good.
The medium frequency induction heating power supply uses the principle of electromagnetic induction, which can penetrate non-metallic substances and instantly induce heat to any metal in a non-contact form. When it heats the U-shaped bolts, the heating speed is very fast, and the workpiece can be heated in a short period of time. The required temperature is reached within a short time, so that the surface oxidation and decarburization of the workpiece are light, and the heating effect of the U-bolt is guaranteed. Even better, the medium-frequency induction heating power supply does not need to heat the workpiece as a whole, but can selectively perform local heating (the heating of U-shaped bolts is a typical local heating), so the power consumption is small and the deformation of the workpiece is small.
Anyone who understands the heat treatment process of U-shaped bolts knows that U-shaped bolts are heated to prepare for the next process, and after heating, they need to be bent with a bending machine. As for how much equipment should be used for heating and heat treatment, this has to be determined according to the specifications of the workpiece and the requirements of the customer.
