no silver bullet. Since USS is already invested in the market‚ they will have to go through a difficult‚ and expensive‚ change‚ or they will end up perishing as the industry changes around them. USS current decided to stay with conventional continuous casting technology simply because they were looking at the shorter-term future‚ and was not willing to take the financial hit and risk associated with a new disruptive technology. Additionally‚ they were tying themselves to the requirements of the current

Melt the material (metal) 2. Pour it into a mold 3. Let it freeze Refractory mold pour liquid metal solidify‚ remove finish Capabilities and Advantages • Versatile: complex geometry‚ internal cavities

not sign the proposal. My recommendation is based on understanding the basic nature of disruptive technologies‚ and their future impact on the steel industry. Kappmeyer is currently making the decision based on short-term gains. With this proposal USX will have 2.6M ton capacity which 3 times greater than Nucor’s 0.8 M ton but the conventional method is not sustainable on a long term basis. CSP technology currently does not fit in Kappmeyer’s upgrade of the Mon Valley plant due to physical locations

What is meant by casting shadows instead of light? Give an example of someone you have observed and their behavior that "cast shadows". (It could be someone in Politics‚ at work‚ or even in your family. (Just remember that other students will read your post) What do you think were the effects of the shadow they cast? Casting shadows focuses on leaders who project shadows of their inner darkness. A person who this student has observed casting shadows in their behavior is a previous general manager

1.0 Calculations 1.1 Sizing of component (including Shrinkage allowance) When cooling from molten state‚ all metals decrease in volume. When cold‚ casting will be smaller than their pattern. In order for parts to be of correct size‚ patterns are made larger to allow shrinkage. The extra size is called Shrinkage Allowance. Different metals have different Shrinkage Allowances. For the purpose of our project‚ we have been using Brass having shrinkage allowance of 1.5%. Length Nominal

Casting Defects: Some defects are common to any and all process. These defects are illustrated in figure briefly described in the following: [pic] A) Misruns: A Misrun is a casting that has solidified before completely filling the mold cavity. Typical causes include 1) Fluidity of the molten metal is insufficient‚ 2) Pouring Temperature is too low‚ 3) Pouring is done too slowly and/or 4) Cross section of the mold cavity is too thin. b) Cold Shut: A cold shut occurs when two portion

Introduction A sand casting or a sand molded casting is a cast part produced by forming a mold from a sand mixture and pouring molten liquid metal into the cavity in the mold. The mold is then cooled until the metal has solidified. In the last stage the casting is separated from the mold. There are six steps in this process: (see sketch below): 1. Place a pattern in sand to create a mold. 2. Incorporate a gating system. 3. Remove the pattern. 4. Fill the mold cavity with molten metal
