    中频炉的利和弊关系 中频炉中的炉料是自身产生热量的，因此比其它间接式加热效率高，电耗低、金属烧损小、对电网、对空气的污染低，所以到目前为止仍然是熔化各种金属最有效、最环保的设备。为了中频炉进一步节能、环保，国内已经有中频炉制造厂家开发最先进的—固态中频炉（串联逆变电路、调频调功），其省电10%，对电网的干扰减少一半 。 事物总是有其利，也有其弊。 中频炉由于是感应加热，炉料、炉壳都存在感应电。特别是大吨位的炉子和节能、环保的固态中频炉，其感应电更高。另外中频炉的炉衬厚度相对较薄。因此使用中尤其要注意安全。 中频炉和煤气燃烧炉在我们兴化地区使用量大、面广，为地方经济的发展提供了不少帮助。但我们要特别重视中频炉和煤气燃烧炉的安全使用。 The pros and cons of induction melting furnace The charge in the induction melting furnace generates heat by itself, so it has higher efficiency than other indirect heating, low power consumption, low metal burnout, low pollution to the power grid and air, so it is still the most effective way to melt all kinds of metals so far. Effective and most environmentally friendly equipment. In order to further save energy and protect the environment, domestic manufacturers of induction melting furnaces have developed the most advanced solid-state induction melting furnace (series inverter circuit, frequency modulation power adjustment), which saves 10% of electricity and reduces the interference to the power grid by half. Things always have their advantages and disadvantages. Since the induction melting furnace is induction heating, induction electricity exists in the charge and the furnace shell. In particular, large-tonnage furnaces and energy-saving, environmentally-friendly solid-state induction melting furnaces have higher induction power. In addition, the thickness of the lining of the induction melting furnace is relatively thin. Therefore, pay special attention to safety during use. Induction melting furnaces and gas burning furnaces are widely used and widely used in our Xinghua area, which has provided a lot of help for the development of the local economy. But we must pay special attention to the safe use of induction melting furnaces and gas burning furnaces.
