Introduction
Ductile iron (also known as spheroidal graphite iron, abbreviated SG Iron or SG) is a type of cast iron. It has a nodular graphite shape in a matrix formed by ferrite, pearlite, and sometimes ferrite-pearlite. It is stronger, more ductile, and more fatigue resistant than tr......

Construction of Double ellipsoidal Cooling Tower
Double ellipsoidal cooling towers (DECTs) are special towers designed by the innovator of energy efficiency designed to provide the most efficient cooling process for a wide range of applications. DECTs can also be used in certain more “technical......
Basic structure characteristics of gray cast iron
Introduction
Gray cast iron is a kind of cast iron with the main constituent elements of iron, carbon and silicon. It is an alloy material that has been widely used in automobile, machinery, heat exchanger and other fields due to its good casting performance, low cost and good mechanical properti......
Oval-Square Hole System
ellipsoidal Baffle Systems
The ellipsoidal baffle system is a device that provides acoustic performance in reverberation spaces without the need for physically separate absorption and reflection panels. This article describes the features and features of an ellipsoidal baffle system and tries to ......
Discussion and Analysis of Ductile Iron and Its Poor Nodularization
An Analysis of Steel Ball and Its Problem of Poor Balling
Steel ball, also known as steel ball, is a kind of metal ball made of carbon steel. Its purpose is mainly used to reduce the impact force and play as a grinding and wear-resistant material. Steel balls have a wide range of applications and......
Oval shape of continuous casting round billet
The Elliptical Shape of the Continuous Cast Round Billet
Continuous casting is one of the key advances in steel production. The technology involves pouring liquid steel from a furnace into a special vessel, where a cylindrical mold moves along its length and pulls the steel in a continuous stran......
Microstructure of magnesia chromium refractories
Microstructure of Magnesium Chromium Refractory Materials
The microstructure of magnesium chromium refractory materials is a key factor affecting their physical and chemical properties. Magnesium chromium refractory materials are usually composed of magnesia and chromite. Their microstructure cha......
Low microstructure and non-metallic inclusions in 50Mn steel (hot rolled and slow cooled)
Abstract
This paper studies the low-magnification microstructure and non-metallic inclusions of 50Mn hot-rolled steel. Optical microscopy (OM) and scanning electronmicroscopy (SEM)were used to study the microstructure of 50Mnhot-rolled steel. The results showed that the microstructure was a mixtu......
(Mn, Fe)S Inclusions in 5CrNiMo Steel
Abstract
Manganese and Iron-based sulfide inclusions (Mn-Fe-S) are major contributors to the many mechanical properties of 5CrNiMo steel. In this paper, the formation, occurrence, and microstructure of Mn-Fe-S inclusions were studied. It was found that Mn-Fe-S inclusions form mainly due to the se......
Metallographic structure of 86CrMoV7 cold rolling work roll electroslag ingot
Abstract
The present research study was conducted to investigate the composition and microstructure of the 86CrMoV7 cold-work rolls’ steel billet. To identify the appropriate composition and properties of the material for production of cold work rolls, a thermite process was adopted for refineme......
