Abstract

The invention discloses a preparing technology capable of improving the quality of a nickel-magnesium nodulizing agent. The nickel-magnesium nodulizing agent comprises components of Ni and Mg. The preparing technology of the nickel-magnesium nodulizing agent is conducted according to the following steps that firstly, calculation is conducted according to the proportion of the content of all components, a cosolvent is prepared, and the cosolvent is composed of magnesium fluoride and calcium fluoride and is a binary cosolvent; secondly, a magnesium ingot is put at the bottom of an intermediate-frequency induction electric furnace and is covered with the cosolvent, and the cosolvent is covered with a first nickel plate; thirdly, after the objects in the furnace are completed melted, a second nickel plate is then added; and fourthly, the intermediate-frequency induction electric furnace is stirred, then standing is conducted for 10 min to 15 min, the cosolvent is completely melted on the upper surface of the fused nodulizing agent, the power of the intermediate-frequency induction electric furnace is reduced to zero, the cosolvent on the surface of melt is removed, and then the melt is then poured into a nodulizing agent die.

Description

technical field [0001] The invention relates to a nodulizer, in particular to a preparation process capable of improving the quality of the nickel-magnesium nodulizer. Background technique [0002] Nickel-magnesium nodulizer is an intermediate alloy obtained by high-temperature melting of metal nickel and metal magnesium. For nickel-magnesium nodulizer, since the melting point of nickel is 1452°C and the melting point of magnesium is 650°C, the melting temperatures of nickel and magnesium are quite different. Metal magnesium also has the characteristics of high vapor pressure; and the intermetallic compound formed by nickel and magnesium is unstable at high temperature, and magnesium is easily oxidized to form magnesium oxide, which causes alloy powdering and reduces the yield of magnesium metal. [0003] Controlling the content of magnesium oxide is an important indicator for the production of nodulizers. Magnesium oxide is an invalid magnesium in the nodulizer, the higher...
