Embodiment 1
[0026] see Figure 1~2 , in an embodiment of the present invention, a high-strength metamorphic alloy hammer head for a sand making machine includes a hammer body 1 with a cuboid structure, and a mounting hole 2 is opened at the center of the hammer body 1; the bottom of the hammer body 1 corresponds to the mounting hole 2 is provided with a plurality of key grooves 3, and the plurality of key grooves 3 are equidistantly arranged on the periphery of the mounting hole 2 along the circumference. The firmness of the connection with the transmission rod of the sand making machine;
[0027] The top of the hammer body 1 is provided with a plurality of positioning components corresponding to the position of the mounting hole 2, and a plurality of positioning components are equidistantly arranged on the periphery of the mounting hole 2 along the circumferential direction. Specifically, the positioning components include snapping Block 41, the engaging block 41 is arc-shaped, the bott...
Embodiment 2
[0031] This embodiment provides a masterbatch for making hammerheads, the masterbatch is composed of the following components according to mass percentage: 0.003% tin, 1.19% manganese, 3.40% sodium chloride, 4.65% chromium, and the balance is iron .
[0032] The preparation method of described master batch comprises the following steps:
[0033] 1) Add 2 times the mass of water to sodium chloride to prepare a sodium chloride solution, then put the iron, tin and sodium chloride solution into the reaction kettle and seal it, and heat it at 450°C for 8 minutes; get the first mixture;
[0034] 2) Put the first mixture into the melting furnace and melt it at 860°C for 20 minutes to obtain the second mixture;
[0035] 3) Add chromium to the second mixture, raise the temperature to 1050°C and continue smelting for 5 minutes while removing slag to obtain the third mixture;
[0036] 4) Add manganese into the third mixture, continue smelting at a temperature of 1050°C for 40 minutes,...
Embodiment 3
[0040] This embodiment provides a masterbatch for making hammerheads, the masterbatch is composed of the following components according to mass percentage: 0.0035% tin, 1.20% manganese, 3.42% sodium chloride, 4.68% chromium, and the balance is iron .
[0041] The preparation method of described master batch comprises the following steps:
[0042] 1) Add 3 times the mass of water to sodium chloride to prepare a sodium chloride solution, then put the iron, tin and sodium chloride solution into the reaction kettle and seal it, and heat it at 550°C for 10 minutes; get the first mixture;
[0043] 2) Put the first mixture into the melting furnace and melt it at 900°C for 25 minutes to obtain the second mixture;
[0044] 3) Add chromium to the second mixture, raise the temperature to 1100°C and continue smelting for 8 minutes, and remove slag at the same time to obtain the third mixture;
[0045] 4) Add manganese into the third mixture, continue smelting at 1100°C for 50 minutes, ...
