In the circulating cooling water system, due to the inlet water quality and other reasons, it often leads to scale and corrosion. At the same time, there will be a large number of bacteria breeding, thus forming dirt. This paper will introduce the common control methods of scale and dirt in circulating cooling water.

Fault phenomenon: frequently burn out the thyristor components, and burn out immediately after replacing the new thyristor.

What should be paid attention to in order to ensure safety in the smelting process of medium frequency furnace

The lining of medium frequency furnace depends on the size of the furnace to decide whether to use castable or ramming material.

According to the data of some developed countries, China’s transmission line loss rate is much higher than that of the United States. 

In order to maximize the productivity of the induction heating device, the heating time should be as short as possible.

Medium frequency furnace is a kind of equipment used for casting, forging and hot processing. It is composed of frequency conversion device, furnace body and furnace front control.

Medium frequency furnace is a heating equipment that converts electric energy into heat energy. All the time, the energy saving and consumption reduction of medium frequency furnace and the reduction of production cost are the focus of enterprises. As we all know, the calculation formula of electric power of medium frequency furnace is p (consumed power) = LXL (square of current) XR (equivalent resistance of medium frequency furnace). Therefore, it can be seen that as long as the current is small, the power of medium frequency furnace will become small.

In recent years, with the development of science and technology and the improvement of product quality requirements, many jewelry manufacturers and handicraft manufacturers have chosen to use medium frequency furnace for smelting non-ferrous metals and achieved remarkable results. So what are the advantages of medium frequency furnace in metal smelting?

The startup equipment cannot start normally

Fault phenomenon: the equipment cannot be started. When starting, only the DC ammeter has indication, and there is no indication of DC voltage and intermediate frequency voltage.

The main differences between power frequency furnace and medium frequency induction furnace are as follows
