Induction Furnace Cast Iron (ductile iron) should pay attention to the problem
Cupola Melting of 0.2% ~ 0.4%. (4) scrap, scrap metal, recycled iron and steel chips melting molten iron, for C, Si,[link widoczny dla zalogowanych], Mn, P, S of, the general increase in sulfur-free induction furnace melting process, it contains less than s, close to the steel When the sulfur content of liquid will lead to breeding difficulties,[link widoczny dla zalogowanych], the use of liquid iron hatchery 75FeSi less significant; use with a small amount of Mg and RE inoculant or a 55 - casting technology and experience exchange - toughness of high chromium cast iron wear Article ID :1003 -8345 improving (2000) 04-0056-04 toughness of high chromium cast iron to improve anti-wear type!

Anewprocesstoincreasetoughnesswasproposed, andexcellentresulthaeenobtainedinthepracticeKeywords: hi Qu chromiumwhiteiron; toughness; newprocess0 introduction of high chromium white cast iron is today one of the best anti-wear materials, in the mining, power generation, building materials are widely used in industry and non-alloy and low Taijin White than cast iron, it sets a higher hardness, MC, carbides,[link widoczny dla zalogowanych], and the distribution was lath isolated,[link widoczny dla zalogowanych], surrounded by the plastic substrate, so brittle relatively small. And after annealing can be thread cutting and vehicles, which created the conditions for its application. But it is still cast iron, ductile than other metal materials, or too low, the production process is easy to produce cracks and scrapped. This paper argues that the production of high-ming, cast iron should pay attention to the problem, 9 ~ - ~ r Shaoti high toughness of the new technology, new technologies, for reference. 1, the microstructure of high chromium cast iron microstructure of high chromium cast iron generally contain no more than 40% of the high hardness of the MC carbide, to ensure its abrasion resistance, the volume occupied by either the matrix is less than 60%. If the increase in carbon content, the carbonation Received Date: 30 August 2000 Author: Su Ying Lung, male, 1937, 1960, graduated from the Department of Mechanical Engineering, Dalian Polytechnic school, the current National Institute of Beijing University of more materials, research direction: high toughness ductile iron, iron and anti-mushroom comfort grub ductile iron and other things he volume of content increases, improved abrasion resistance, and increased brittleness. Especially the carbon equivalent over 4.3%, the microstructure appears primary carbide, toughness and other mechanical properties are to be significantly reduced. Eutectic cast iron with carbon content of chromium and silicon content varies, and is calculated as follows: C # = 4.3% a 0.31Si 0.05Cr a high abrasion resistance of chromium cast iron matrix in Table 1, Table lCrl5Mo3 the wrong type of cast iron with high abrasion resistance of the matrix on the impact of ... Tab. 1Effectofmatrixs ��nlctuOICrl5Md-typehigh-chromiumc Magpie Iironon song _lp D operIie8 ...: It can be seen from the table, the less the matrix more soft wear, practice shows that, as long as the base reflects the 10% pearlite, it will cause significant wear performance reduced. Sulfur in liquid iron by adding iron, melting with S can increase its capacity to improve their breeding performance. (5) Since the plant scrap, scrap steel chips, melted casting, different kinds of raw materials, induction furnace lining have acidic (SiO ~),[link widoczny dla zalogowanych], alkaline lining (MgO or A10,) different; despite a 56 card No chemical composition of a feather fan is a standard requirement in the smelting of cast iron (ductile iron), in accordance with the reality of the factory, with different melting process, comprehensive C, Si, Mn, P, S effect, then, before pouring with FeSi or FeSiCa inoculation and magnesium ball ball processing agent. t projects
