For the desing of a burner of surface quenching, the fundamental data are demanded on the relations among the kinds of materials, the shape, size and depth of quenching and other functions. We operated the experiment as following : Test specimens : square sheets of 10 X 100 X 200mm and discs of 10mm thick and 390mm diameter. Tips : single and multiple flame orifices. Testing items : (1) Characteristic test of torches; the relation between the length of inner core and the pressure and flow quantiity of gas. (2) Heating capasity of the respective parts of the flame. (3) Quenching characteristics ; influence of the orifice diameter, gas flow and gas velocity on the shape and size of the quenched volume. (4) Diameter and distance of orifices to get an uniform depth of quenched part. (5) Influence of travelling speed of flame on the depth, hardness and end effect of hardened layer.
