Several methods IF furnace quickly determine the merits of the apparatus

The medium frequency melting furnace is a very important equipment for a foundry, and its quality directly affects the production efficiency of the entire foundry. A good medium frequency melting furnace is not only durable and energy efficient, it can save the company a lot of manpower and time costs. Therefore, users can't just price when choosing the medium frequency melting furnace. The following are some suggestions for professional technicians to introduce how to choose a good medium frequency melting furnace equipment:

1. Copper platoon: Whether the connecting copper platoon is the primary color of copper, if it is wrong. Regular electrical equipment copper parts need to be whitened, silver plated best, or tin or nickel. Because the copper watch is easily oxidized and will become more and more serious, the contact resistance will become larger and larger, and the power consumption will gradually increase. A few manufacturers have saved the plating of this ring for the cost of the province. As a result, the manufacturer has saved a small amount of money, but the user has to pay for it for a long time without knowing it. If this little money is to be saved, you have to be alert --- there can be more things on the device.

2 , aluminum shell capacitors: there are common type, standard type, reinforced type, generally can be seen from the appearance size, weight, enhanced type but high price. At present, the 0.75-2000 capacitor technology is immature , although the price is low but the life expectancy is generally not long.

3 , the circuit breaker (open) advantages and disadvantages can also be seen at a glance: the right side of a wooden handle is the elimination model - DW10 or DW16, or you can consult an electrician. This kind of open protection performance is a price that is several times lower. When the equipment is normal, the circuit breaker is just a switch , which seems to be less important . In the event of an accident, this is the last pass of protection. In case of failure, the consequences are unimaginable.

4 , copper has advantages and disadvantages, which also directly affects performance and power consumption. Although the copper tube products can not be seen thick or thin, the appearance can be inferred: the thin copper tube is more likely to be recessed in the middle when it is bent than the thick one, and the concave shape of the induction coil is thin. It is best to specify the thickness of the contract, and buy copper pipe fittings.

5 , reactor: can look at the overall size, including copper tube core size, thickness, copper tube is thick but silicon steel sheet is thin. Silicon steel sheets are generally 10,000 yuan / ton, good tens of thousands / ton. If the reactor is small, the price difference is several thousand yuan. If it is small, it will be easy to use but it will consume more power and affect the protection performance.

6. The radiator is one of the main accessories used on the intermediate frequency equipment. It is easy to notice that the cut-off is the triangular cover on both sides. The normal thickness should be about 5mm , otherwise it is difficult to maintain the rated pressure.How much is the iron value? Even if you have to save a little, you have to be alert!

7. Insulation treatment: Insulation treatment on the surface of the inductor has an important influence on preventing electric furnace fire, arcing, power supply damage, and major safety accidents such as furnace wear. Insulating paint needs good high temperature resistance, adhesion, and waterproof. ability. At present, the general recognition in the industry is to use the TSC-L ultra-high temperature insulating varnish or APC-H+ high-temperature arc-resistant insulating enamel of Shanghai Gengyi Technology Co., Ltd. to insulate the surface of the coil.
