Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized: The water-cooled cable in the medium frequency electric furnace is a special cable connecting the medium frequency power supply and the induction coil. Because the inside of the cable can pass water to achieve the effect of cooling and cooling, it is called a water-cooled cable. Although the water-cooled cable used in the medium frequency electric furnace is also carrying current, its internal structure is different from that of ordinary cables. The water-cooled cable used in the medium frequency electric furnace is composed of electrodes, copper-stranded wires, insulating hoses, water nozzles, and stainless steel hose clamps. The electrode is made of copper rods and is connected to the copper stranded wire for cooling. The insulating rubber tube is sleeved outside the copper-stranded wire and fastened to t

Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized: 1. Hydraulic system: The hydraulic system of the medium frequency, coreless induction furnace is used to pour molten metal out of the furnace, and to open and close the furnace cover. To ensure reliable work, the hydraulic station of the electric furnace should be equipped with two main pumps of the same specification (one for use and one for backup). The inlet end of the tilting furnace hydraulic cylinder needs to be equipped with a throttle valve to prevent the furnace body from falling suddenly due to the loss of pressure in the hydraulic system. When the power supply is interrupted for a long time, the molten metal in the electric furnace may cool and solidify. This situation may damage the furnace lining. It is very dangerous to melt the solidified metal in the furnace by operating the electric furnace.

Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized: Medium frequency induction furnace is a kind of three-phase power frequency alternating current, rectified into direct current, and then the direct current into an adjustable current, supplying the alternating current flowing through the capacitor and the induction coil, and generating high density in the induction coil The magnetic lines of force and cut the metal material contained in the induction coil, which produces a large eddy current in the metal material. This kind of eddy current also has some properties of medium frequency current, that is, the free electrons of the metal itself flow in the resistive metal body to generate heat. The medium frequency electric furnace uses a medium frequency power supply to establish a medium-frequency magnetic field, which induces eddy currents and heat generatio

What are the safety protection measures for medium frequency electric furnaces?

Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized: 1. Cooling water system 　 The role of the water cooling system in the medium frequency induction furnace. During the daily use of the medium frequency induction furnace, some components will generate huge heat, such as the medium frequency power supply, induction coil, water cable, etc. One way to solve this problem is to use a water cooling system for cooling. It can be seen that these system components all need water for cooling, and the probability of furnace equipment damage due to cooling water failure is high, so water is very important for furnace equipment. On the other hand, because most of the devices being cooled are charged objects, such as thyristors, induction coils, water cables, etc., the conductivity of the cooling water directly cooling these devices must be lower than the speci
