After reading the magazine in 1962, No. 4, Comrade Xuhui Quan “before the test of molten iron in the use of circular test stick ” article, I feel very inspired. However, the round test bar and triangle test block in the production of which kind of easy to operate at the same time more accurately determine the chemical composition of hot metal, according to our factory from the use of round test sticks and then use the triangular test block for furnace control After the hot metal composition, put forward a personal opinion for discussion. Triangle test block than the round test stick easy to grasp in the operation, fast and accurate. round
