Embodiment 3
[0039] A kind of ax with long service life of the present invention is made of the following raw materials according to parts by weight:
[0040] Scrap steel: 350 parts, returned charge: 220 parts, ferrosilicon: 5 parts, ferromanganese: 12 parts, ferrochrome: 12 parts; carbon: 0.40 parts; slag remover: 0.03 parts; deoxidizer: 0.05 parts.
[0041] The above-mentioned production method of an ax with a long service life comprises the following steps:
[0042] a. Take scrap steel, recycled materials, ferrosilicon, ferromanganese, ferrochrome, carbon, slag remover and deoxidizer in the above ratio;
[0043] b. Put steel scrap into the smelting furnace first, then add ferromanganese and ferrosilicon in turn, turn on the smelting furnace, turn the button clockwise widely until the limit indicator light is on, and keep stirring at the same time;
[0044] c. After 20-25 minutes of smelting in step b, add back charge, ferrochrome and carbon, stir continuously, and smelt for 20 minutes ...

The invention discloses an axe long in service life and a production method thereof. The axe long in service life is prepared from, by weight, 280-350 parts of steel scrap, 150-220 parts of scrap returns, 3-5 parts of ferrosilicon, 5-12 parts of ferromanganese, 7-12 parts of ferrochromium, 0.24-0.40 part of carbon, 0.02-0.03 part of deslagging agents, and 0.02-0.05 part of deoxidizing agents. Theproduction method of the axe comprises the steps of fetching, mixing, smelting, purification, deoxidization, casting, cutting and finish grinding. According to the axe long in service life, the ferromanganese and the ferrosilicon are added, so that it is ensured that the axe has tenacity, corrosion resistance, abrasion resistance and the capacity to bear impact loads; and meanwhile, the scrap steel and the scrap returns are added so that the production cost of the produced axe can be reduced, and compared with an ordinary steel axe, the axe produced through the production method is longer in service life, and safe and reliable in use.
Description
technical field [0001] The invention relates to an agricultural tool and a production method thereof, in particular to an ax with long service life and a production method thereof. Background technique [0002] The ax is mainly used for chopping and chopping objects. When chopping wood and felling trees, when the ax is used to chop with great force, there will be a problem that the ax is caught in the firewood and the stump and it is difficult to pull it out smoothly, which will affect the use effect and reduce work efficiency; at the same time, due to the frequent use of the ax, it will cause The existing axes have the disadvantages of poor toughness, weak corrosion ability, non-abrasion resistance and short service life. Contents of the invention [0003] The object of the present invention is to provide an ax head with strong wear resistance and high hardness and long service life. [0004] In order to achieve the above object, a kind of ax with long service life of t...
