快速判断中频炉设备优劣的几点方法2019

1、铜排：连接铜排是否为紫铜的原色，如是就不对了。正规电力设备铜件均需镀白，镀银最好，也可镀锡或镍。因为铜表易氧化，而且会越来越严重，接触电阻会越来越大，电耗也随着慢慢增加。少数厂家为省成本把镀这一环省了，结果厂商省了点小钱，用户却要不知不觉中为此长期买单。如果这点小钱都要省，您要警觉了----设备上能省的东西可多了。

2、铝壳电容器：有普通型、标准型、加强型，一般从外表尺寸、重量可看出来，加强型较好但价高。目前0.75-2000电容技术不成熟,虽价低但寿命普遍不长。

3、断路器（空开）优劣也一看便知：右边有个木柄的属淘汰型号--DW10或DW16,或可咨询电工。这种空开保护性能差价格要低好几倍。设备正常时断路器只是一个开关,似乎不太重要,事故时这可是保护的最后一道关口，万一不灵后果不堪设想。

4、铜材有优劣厚薄，这也直接影响性能与电耗。铜管制品虽看不到厚薄，但外表还是可推断的：薄的铜管在弯制时比厚的更容易中间凹陷，象感应圈凹得厉害的定是薄的。最好合同注明厚度，买铜管类配件要论斤不要论数。

5、电抗器：可看整体的大小，包括铜管铁芯大小、厚薄，铜管是厚的好但硅钢片是薄的好。硅钢片一般上万元/吨，好的几万元/吨。电抗器小一级就差价几千元，小了也好用但会更耗电又影响保护性能。

6、散热器是中频设备上用得较多的主要配件之一，比较容易察觉偷工减料的是两边的三角盖，正常厚度应为5mm左右，否则很难维持额定压力。铁值几钱？连这也要省一点您可要警觉了！

7、绝缘处理：感应器表面的绝缘处理对于防止电炉打火，拉弧，杜绝电源损坏，穿炉等重大安全事故有重要的影响，绝缘漆需要有良好的耐高温能力，附着力，以及防水能力。目前行业内普遍认可度较高的是使用上海更益科技公司的TSC-L超高温绝缘漆或者APC-H+高温抗弧绝缘瓷漆对线圈表面进行绝缘处理。

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.
