ABSTRACT:
Radiator particularly for blast furnaces has a shape of plate and outer box 1 made of cast iron with 1% addition of chromium. Inside outer wall of the box there is installed a cooling coil 2. From the interior the radiator is provided with a lining of semi-graphite sections.
Method of production of the radiator consists in preparing a form of cement mix for casting the box in a floor by using a model, after hardening mold cavity is spreaded with a protective coating, preferably water-graphite one and after the mold is dried there are placed semi-graphite sections. To the top portion of the form, made of chamotte mass, there is fixed a cooling coil and the whole form is filled with cast iron by the hitherto applied method. For cast iron there is used the addition of 1% of chromium, being introduced in a form of self-meltable ferrochromium preferably into the vat.
