かなかりた事そ言い添えておく。As a result of an actual machine test by physically welding to both ends or one end of the body of a striking plate (also known as an impact blade) that crushes limestone, bricks, and coke, we found that conventional high-carbon, high-chromium welding rods (CW%, 0r28.7%) had a durability of 3 weeks, but when a high speed steel welding rod was used, the durability was 10 weeks. As a result of overlaying on the wood and conducting an actual machine test similar to the above-mentioned striking plate, the service life was 2 months.It should be noted that the conventional product had a service life of only 1 month.

Fuji Kogyosho Co., Ltd. 4, Agent address: 1-1O-27 Hakataeki Higashi, Hakata-ku, Fukuoka City (1) "Name of the invention" in the application form: 0 (2) Specification Description 1: Name of the invention: High hardness coated arc Welding Material 2, Claim 1, is a welding rod in which the peripheral wall of a mild steel core wire is coated with a mixture of workability flux and alloy flux, wherein the workability flux is 40 to 50% by weight of the whole. The balance is alloy flux, which contains 50% by weight or less of ferrosilicon, 40 to 100% by weight of metallic manganese, and 15.0 to 30.0% by weight of ferromolybdenum. Ferrotungsten 2.0-8.01i%, Ferrovanadium 5.0-100% by weight, Cobalt metal 5.0
Welding materials for high hardness coatings, such as those consisting of ~100 weight percent, weight - 50 to 10.0 weight percent carbide, and 10 to 3.0 weight percent graphite. 3. Detailed Description of the Invention The present invention relates to a coated arc welding material. Overlay welding materials that are rich in crack resistance and have excellent high hardness are desired not only in the steel industry but also in various mining industries. Conventionally, high carbon, high chromium materials (e.g. C3.0% by weight, Cr Z8.7% by weight) were mainly used as this type of welding material, but the requirements for various mechanical parts are becoming increasingly severe. As the age of wear and tear has increased, there has been a demand for materials that are even more wear resistant. The present invention aims to provide a welding material that satisfies the above-mentioned needs, and its gist is a welding material in which the peripheral wall of a soft alignment wire is coated with a mixture of workability flux and alloy flux. The workable flux is 40 to 50% by weight of the whole.2 The balance is alloy flux, and the alloy flux is 5.0% by weight or less of ferrosilicon, 40 to 10.0% by weight of metallic manganese, p-ferromolybdenum 15 .0 to 30.0% by weight, ferrotungsten 20
~8.0% by weight, ferrovanadium 50-100% by weight, cobalt metal 50-10.0% by weight. Chrome carbide 50-100% by weight I graphite 1.0
This is a high hardness coated arc welding material consisting of ~30% by weight. Incidentally, the chemical composition of the deposited metal obtained by performing covered arc welding using the material of the present invention was as follows. C: 0.8-1.2% by weight, Si: 0.05-0
．． 50% by weight Mn: 0.5-1.5% by weight, Cr:
3.5-5.5% by weight Mo: 7. O ~ 9.0% by weight, V: 1.0 ~ 1.8% by weight Co: 2.0 ~ 6
．． 0% by weight, W: 1.0 to 3.0% by weight. The material of the present invention is used in the cement manufacturing industry, quarrying industry, ceramic industry, iron manufacturing industry, etc. as shown in FIGS. 1 and 2. As a result of an actual machine test by overlay welding on both ends or one end of the main body of a striking plate (also called impact blade) that crushes two limestone stones, bricks, and coke, we found that conventional high-carbon, high-chromium welding rods (C3.0% by weight, Cr287 heavy background)
The heavy cladding was durable for 3 weeks, but when the material of the present invention was used, the durability was 10 weeks. Next, we will examine the high hardness of the annealing furnace rolls, m-washing bath rolls, pinch rolls, leveler rolls, cradle rolls, bending rolls, loop car rolls, etc. other than the alkaline bath rolls in steel mill cold rolling equipment. Cold rolling rolls (
3 and 4) was tested on an actual machine as shown below. Conventionally, SUJ type 2 (hardness Hv830) was used for the leveler roll, but the present invention material was used for cover welding. The roll, which was overlaid with a thickness of 6 mm on one side and tempered at 550°C, exhibited twice the wear resistance of the conventional four-roll roll. Furthermore, cement manufacturing and quarrying using low alloy steel or ordinary steel as shown in FIGS. 5 and 6. The material of the present invention is overlaid and welded to both ends or one end of a striking plate for crushing two limestone stones or bricks in the ceramics industry, etc.
The impact plate for crushing was tested on an actual machine, and the results were as follows. That is, while the conventional product using 11 types of SCλInH had a lifespan of one month, the product of the present invention had a lifespan of two months, which is twice as long. As mentioned above, the material of the present invention has high hardness (high wear resistance) and excellent crack resistance, so it can be widely used in the various uses mentioned above. 4. Brief description of the drawings Fig. 1 is a cross-sectional explanatory diagram of a chorus crushing impact plate to which the material of the present invention is applied, Fig. 2 is a sectional view taken along line n-I in Fig. A perspective view of a roll for cold rolling using the material of the present invention, FIG. 4 is a cross-sectional view taken along the line I-If in FIG. 3, and FIG. ,
