As the basis of malleable iron pipe fittings,the composition and temperature of iron water have great influence on the material properties of pipe fittings.Therefore,strict control of elements in iron and water,also good control of iron and water discharge and casting temperature,is the basis of making good malleable iron pipe fittings.

Blast furnace smelting and electric furnace smelting have their advantages and disadvantages respectively.The overheating performance of molten iron in blast furnace is good.Because the coke is needed in the process of smelting iron in blast furnace,so the carbon content in the molten in the molten iron is suitable.While the coke is not needed in the electric furnace,in addition,the oxygen oxidation of carbon and air in the process of molten iron will reduce the carbon content in the molten iron.However it is difficult to control the composition of iron and water in blast furnace,and the control of iron and water composition in electric furnace is convenient for the composition can be adjusted at any time.

We adopt the double smelting furnace technology adjusted by blast furnace smelting and electric furnace,use the low cost of blast furnace smelting and control of molten water temperature and carbon content advantages, along with electric furnace for the component temperature further adjustment,ensure that the proportion of the various components of the galvanized pipe fittings.
