Embodiment 1

[0024] Embodiment one, such as figure 1 As shown, a production method of utilizing industrial waste to smelt crude iron according to an embodiment of the present invention comprises the following steps:

[0025] S1: Collecting materials: collect waste after industrial processing such as lathes, and divide the waste into four categories: pure iron waste, low-carbon waste, medium-carbon waste, and high-carbon waste according to the carbon content in the raw materials during processing;

[0026] S2: Material pretreatment: Pour the four collected materials into the iron drum at a ratio of 25% each, and use tools to stir the waste so that the waste is evenly distributed in the iron drum;

[0027] S3: Smelting waste: Put the iron drum containing the waste into the furnace to heat it to 1200°C-1300°C. When the waste starts to turn red and soften, take out the melted materials. Since the iron sheet of the iron drum is relatively thin , at 1200-1300°C, most of the iron sheet is burnt;...

Embodiment 2

[0031] Embodiment two, such as figure 1 As shown, in S5, the forged iron block is generally cut into three to six pieces.

Embodiment 3

[0032] Embodiment three, such as figure 1 As shown, in S6, the number of times of folding and forging is generally three to six times, which can avoid the effect of losing the hairy iron and cow hair pattern due to too many times.

[0033] In order to facilitate the understanding of the above-mentioned technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0034] Generally speaking, it is more environmentally friendly to use the waste after industrial processing for processing. On the one hand, it is more environmentally friendly to reuse the waste. On the other hand, the waste after industrial processing can be continuously obtained, which is more convenient than salvaging iron sand in the river, and the output is larger; because The waste after industrial processing is used, and the sword cast after forging also has the effect of hairy iron and cow hair; because ...

Abstract

The invention discloses a production method for smelting crude iron by using industrial wastes. The production method for smelting the crude iron by using the industrial wastes comprises the followingsteps of, 1, collecting materials, and specifically, wastes which are subjected to industrial machining such as a lathe and the like are collected, and the wastes are divided into four grades, namelypure iron wastes, low-carbon wastes, medium-carbon wastes and high-carbon wastes according to the carbon content in the raw materials during machining; 2, pretreating the materials, and specifically,the four collected materials are poured into an iron bucket according to the proportion of 25% correspondingly, and the wastes are stirred by using a tool, so that the wastes are uniformly distributed in the iron bucket; 3, smelting the wastes, and specifically, the iron bucket filled with the wastes are put into a furnace to be heated to 1200-1300 DEG C, the molten materials are taken out afterthe wastes begin to turn red and soften, and most of iron sheets are burnt out at 1200-1300 DEG C due to the fact that the iron sheets of the iron bucket are thin; and 4, polishing the iron sheets, and specifically, after the melted materials are cooled to the natural temperature, the iron sheets with the incompletely-evaporated material skin is polished.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a production method for smelting rough iron by using industrial waste. Background technique [0002] The raw iron is smelted by the ancient swordsmiths in Longquan with the local method. The material is selected from the high-quality iron sand in the Longquan River. It is wrought iron that has just come out of the furnace and has not been hammered. Refined into steel; generally ten catties of rough iron can cast an ancient Longquan sword; rough iron has good adhesion and can be forged with other metals. Unlike industrial steel, which contains many impurities such as manganese and sulfur, the resulting sword is easily brittle. ;In order to achieve the effect of combining rigidity and softness in the sword, swordsmiths often have to continuously fold and compound iron blocks, hammering and refining; the sword mixed with wool iron has whitening of the sword body, and it has the app...
