Ceramic additives to improve the role of collapsibility

Surface decarburization of steel by carbon or by adding carbon material, there is another role, that is, when hot metal poured into the back, the carbon to dissolve the gold chip solution, extended 32 \Universe 4. tarsal charge type specimen nail on the South suddenly swelled the stability of R-inch ring was. eliminate the forging die steel and other alloy steel castings rain decarbonization of the table. test showed that the casting surface removal, cut its hardness is low, HRc30 generally only about the life of effectiveness and heat treatment. the general requirements of the surface hardness of die steel HRc48 so, after adding attachment hardness values measured in HRc50 so, can meet the requirement. In order to test for carbon or decarburization effects of resin-containing ceramic additions in the pouring of steel castings, electronic scanning and spectral sampling determined by the casting surface to the center of the carbon content is essentially the same. ④ appendages on the ceramic surface finish of the appendages ceramic powder are added to the powder, the molding process of filling does not produce additional requirements, the uniformity of slurry is still good. so the surface finish of ceramic type had no effect, the ceramic mold surface roughness Ra approximately equal to 5 micron. Third, the production of pilot production tests selected steel bevel gear production of small quantities of pouring test. corundum powder with the original manufacturer of ceramic production of the gear parts, the main problem is the production of Hand sand, the gear teeth on the cast and the hole in the ceramic core of the collapse and the enemy of the poor. sand difficulties,[link widoczny dla zalogowanych], high labor intensity, low production efficiency. test developed by screening using two additions , ① carbon materials GL-l. @ resin materials, a 2 DM. were added to the sample made of ceramic powder in its residual strength compared in Figure 5. appendages were made of the above ceramic , casting gear castings, sand and then compare the performance to assess their! collapsibility excellent dioxin Zhai Pa Tan Man | Yu-cut potato fields and ancient tarsal 6 plus Ao Tao Qu stool test loop type high cliff on the Tibetan town just bad, The results shown in Table 3, casting experiments show that the ceramic material sintered corundum serious, oxide layer and the sintered layer of clear boundaries, thick sintered layer, make sand time and effort. bauxite ceramic material poured back more induration, intensity is high. and ceramic raw materials at these two kinds of additives added, the sand effects are significantly improved. contains a section on the attachment of ceramic, or sintered oxide can not see the boundaries of repeated, organization Kun loose,[link widoczny dla zalogowanych], with dark gray color translation casting bright, clean sand and time significantly reduced labor intensity, casting quality requirements are met. IV, Conclusion 1. by microscopic analysis, samples are measured and poured Zhu proved validation, the selected ceramic additives to improve the collapsing mining;. a wall of ceramic Ho Wei Note is issued to see the contrast to the situation saying the type number when you hear pouring sand back South porcelain mandarin duck-shaped cross-section of sand-like chaos hit home, please corundum 8 to l0 l garlic bell boat boundary of two oxidation even 0. $ mm. ship knot layer 6mm, sand effort.

Qing Kang to teach after a clean tooth When I asked to clean copy is continuous with a hammer and a transcript of the Stanford Zi 2l in ten small teeth clean-up of the results are obvious. Low 2. Because attachment is a powder, directly into the ceramic powder, the process is simple, do not grouting of ceramic formability. 3. appendages inexpensive and light weight, an increase of slurry-off product, can reduce the amount of powder, so that the cost of ceramic reduction 4. appendages for a variety of ceramic mold material false in sintering can reduce the degree of residual strength can drop around T0.
