The idea of schematic diagrams came into existence somewhere in 1300 A.D. when the first-ever geographical map, which is now known as Atlas, was drawn. Later, the same concept was used to draw the maps of stars and constellations. As time passed, the structure of the schematic diagrams modified, and somewhere in the 20th century, …
An open hearth furnace has a lining of refractory and a low, arched roof that covers the hearth, which is open directly to flames that melt the charge. This process uses about equal amounts of iron and scrap. Steel is produced in an open hearth furnace by the following steps:. 1. A machine dumps limestone and scrap steel (the charge) into the …

A schematic is defined as a picture that shows something in a simple way, using symbols. A schematic diagram is a picture that represents the components of a process, device, or other object using abstract, often standardized symbols and lines. Schematic diagrams only depict the significant components of a system, though some …

How to make a process flow diagram. Creating a process flow diagram is a structured approach to visualizing and understanding the steps and flow of a process. Whether you're mapping a complex manufacturing operation or a simple business procedure, a clear and accurate PFD is invaluable. Let's dive into the steps necessary to create an effective ...
The schematic diagram of the modeling method is shown in Fig. ... LF refining slag-making is an important procedure in the production of clean steel. The traditional slag-making process mainly relies on the experience and skills of the operator and usually requires multiple replenishment of slag-making material to meet the …
The AISE Steel Foundation. Pittsburgh,Pa. 13.3.1 Energy Optimizing Furnace (EOF) The EOF is essentially a batch oxygen steelmaking process with high post-combustion, with coal additions and extensive scrap preheating; a schematic diagram is shown in Fig. 13.3.9 The process theoretically can charge up to scrap, but typically 40–60% …
Continuous Casting of Steel. Seppo Louhenkilpi, in Treatise on Process Metallurgy: Industrial Processes, 2014. Abstract. Continuous casting process has grown into the biggest casting method for steel, exceeding the conventional ingot casting route in the mid-1980s. Nowadays, the continuous casting ratio has reached the level of 95%. …

This blast furnace process is the oldest but still the main method to produce large quantities of molten raw iron, hot metal, and for steel making and foundry purposes. The early blast furnace had about a 6 m × 6 m square formed stone foundation and 6–8 m high walls of stone blocks.
Schematic Diagram of Steel Production. Before casting, the steel can be refined in the ladle by various processes according to the specification with respect to its deoxidation state, inclusion content and level of …
A steelmaking flow chart is a visual representation of the steps involved in producing steel. It outlines each phase, from the initial raw materials to the final steel products, providing a clear and organized …
Figure 2.2 shows schematic sketch of a blast furnace indicating different sections, and Fig. 2.3 shows the general constructional features of a blast furnace. It is circular in cross section and around 30–40 m in height. The outer shell of BF is made of steel plates, and refractory lining is at the inside of shell.
"Process equipment, valves, instruments and pipe lines are tagged with unique identification codes, set up according to their size, material fluid contents, method of connection (screwed, flanged, etc.) and the status (Valves - Normally Closed, Normally Open)."[1] These two diagrams can be used to connect the parameters with the control …
The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon steel: High carbon steel contains up to about 1.5% of carbon. The ...
