Today we are going to discuss with you about the cooling system used in the use of IF induction furnace.
Water cooling system is a very important supporting equipment in the process of metal melting furnace. The parts that need water cooling are these: IF power supply (generator set and SCR frequency conversion device, in which the cooling water used by SCR frequency conversion device needs to be softened), inductor, capacitor, flexible cable, etc.
In order to save water, we usually adopt the method of circulating cooling. Cooling water circulation system includes water pump, closed cooling tower, water tank and so on.
The importance of circulating water system: Melting furnace facilities are high-power power electronic devices. Important components such as silicon controlled, flat-wave reactors, capacitors, induction coils and water-cooled cables all need water cooling. The inner diameter of many cooling pipes is only about 8mm.
If the power of the electric furnace is small, only the circulating pool can be used. The electric furnace with larger power should adopt the way of circulating pool and cooling tower. When designing, we should pay attention to separating the circulating water of the electric furnace and the electric cabinet, because the outlet water temperature of the electric furnace is about 55℃, the outlet water temperature of the electric cabinet is about 40℃, and the temperature difference is more than ten degrees.
If the production line can meet the conditions, or the local water quality is very hard, try to use pure water (distilled water) in the circulation system.
At present, pure water circulation system products have closed (copper tube movement) and heat exchanger type two, the former covers an area of small, but high cost, the latter covers an area of large, but low cost. Both methods can complete the pure water closed cycle to achieve cooling.
Some users in the use of melting furnace, do not pay attention to the configuration of the water cooling system, it will lead to the circulating water temperature is too high, the circulation system into debris, resulting in scaling and water plugging phenomenon, silicon burning, burning reactor these faults, cause unnecessary losses to the whole production line.
We should choose the appropriate cooling method according to the actual situation of our electric furnace.
This is our share today, welcome to pay attention to Luoyang Judian, let us solve more doubts about metal smelting furnace for you.
