Embodiment Construction
[0021] The present invention will be further described in conjunction with the following examples:
[0022] The preparation method of wear-resistant anchor bolts, the processing steps include:
[0023] a. Casting rod material, by weight, first put 12-14 parts of scrap iron into the intermediate frequency electric furnace to melt into molten iron, then add carburant, and then put it in when the temperature in the intermediate frequency electric furnace rises to 1000-1220 °C 0.1-0.2 parts of molybdenum, 30-35 parts of steel ingot, 30-35 parts of steel scrap and 12-16 parts of returned furnace material, and at the same time sprinkle a layer of heat preservation covering agent on the surface of the melt to cover, and then discharge slag, after slag discharge Add 0.5-0.8 parts of nickel-iron alloy, 1-2 parts of silicon-iron alloy, and when the temperature in the intermediate frequency electric furnace rises to 1450 ° C, add 0.4-0.6 parts of magnesium powder into the ladle together ...
