Industrial high wear resistant ball cast iron litje natančnost deli
Ducular železo litje je do pridobiti sferični grafit skozi sferulacijo in gestacijo zdravljenje, kar učinkovito izboljšuje mehanske lastnosti od litega železa, še posebej plastičnost in žilavostc so as as to obtain higher strength than carbon steel. Ductile iron casting is a kind of high strength cast iron material developed in the 1950s. Its comprehensive performance is close to steel. It is based on its excellent performance that it has been been successful used for casting some parts with complex force, high strength, toughness and wear resistance. Ductile iron has rapidly develop u a široko rabljeno cast iron material second only to grey cast iron. The so-called "iron nstead of steel", mainly refers to the ductile iron casting.
funkcija
Bullet iron castings have already been used in almost all major industrial sectors that require high strength, plasticity, toughness, wear resistance, severe heat and mechanical impact resistance, high or low temperature resistance, corrosion resistance, and dimensional stability. In order to meet these changes in use conditions, ductile iron casting provides a wide range of mechanical properties and kissing ductile rational energy.
For example, as stipulated by the International Organization for Standardization 1501083, most of the ductile iron casting is mainly produced in a non-alloy state. Clearly, this range includes high strength signs with tensile strength greater than 800 Newton / mm and 2 percent elongation. At the other extreme is the high plastic plate, with elongation greater than 17 percent and correspondingly lower strength (minimum 370 Newton / mm spoon. Strength and elongation are not the only roots where the designer chooses the material, while other decisive and important properties include yield strength, elastic modulus, wear resistance and fatigue strength, hardness and impact performance. In addition, corrosion resistance and oxidation resistance and electromagnetic performance may be critical for the designers. To meet these special uses, a group of austenitic ball iron was developed, usually called Ao Ni and Resis dead ball iron. These austenitic spheres are mainly alloyed with zinc, chromium and manganese, and are listed in international standards.
Ductile železo litje sestava
Prašič železo je železo ogljik zlitine z vsebnostjo več 2 odstotkov , industrijski svinja železo ogljik vsebina je na splošno 2,5 odstotek -4 odstotek , in vsebuje C, SI%2 c Mn, S, P i drugi elementi, je proizvod od iron ore taljenje po blast peč. Po u razlikuje forme od carbon existence in svinja iron, it can be deljeni na čelik i svinja železo, lito prašič železo in duktile železo litje.
Na padavinah grafit je a sferično lito železo. Delitev učinek sferični grafit na kovina matrica je manjša od da od list grafit, tako da jačina od lit železa doseže 70~9 0 % % od tkivo jakost od matrice, i teza jakost can reach 120kgf / mm2, and it has good toughness. The chemical composition of ductile iron except železo je običajno: vsebnost ogljika 3,6~3,8 odstotka , silikon vsebina 2.0~3.0 odstotek , mangan%% 2c fosfor, sulfur vsebuje ne več od 1,5 % i prikladna količina od redke zemlje, magnezij i ostali sferični agenti.
