In the north, almost every family used cast iron radiator, almost all four column, six O and column airfoil. The surface is sprayed with silver powder paint. It is the characteristic and product of the planned economy. Production determines consumption, production is not rich, consumer choice is less or no choice. At that time, the heating gas of a lot of units The heating is also a kind of welfare, and the heating fee is reimbursed.
Nowadays, the new cast iron radiator is still strong and durable, so warm, it can still be used for more than 50 years to warm our life. The appearance, shape and surface treatment of the cast iron radiator are much more beautiful than in the past. Now many manufacturers have launched more than 10 kinds of shapes, such as curved surface, elliptical surface, plane, plate type, and so on.
Heat inertia is better, corrosion resistance, safety and reliability, long life, long wall heat storage time, corrosion rate is slower than low carbon steel heater, aluminum alloy heater, tank type radiator. Because its corrosion is needle corrosion, not massive corrosion, so rust is not easy to break away from the body, oxygen can not invade the inner body of the inner body to cause deep surface corrosion, so the life span is about 25 years to 30 years. Besides, the cast iron radiator is the cheapest in all types of radiator, which is very economical and affordable.
Because of the material, its aesthetic appearance is relatively backward, and can not be combined with modern architecture and decoration, so many fashion families have been disjointed with cast iron radiator. Moreover, the inner cavity of cast iron radiator is very easy to damage the temperature control device, and the energy consumption of production is also high. The energy saving aspect can not be compared with the new product. In addition, it is now the domestic heating system has been updated to promote efficient and energy-efficient products, so old iron products have been eliminated, and few people choose this kind of heating.
