LEAST COST ALLOY ADDITIONS (TAP)

The Least Cost Alloy Additions program (TAP) is used to calculate the least costly combination of alloys required to meet your “intermediate” or “final” chemistry working aims. TAP utilizes linear programming techniques to obtain the least cost alloys required.

An unlimited number of grade/alloy specifications can be permanently created and accessed by TAP. The program allows you to specify up to 40 individual restrictions per grade/alloy. A restriction can be a specific material, a certain type of material, or an entire file of materials. Restrictions can be expressed as either a fixed weight or a percentage of the prelim weight.

The program allows the user to designate those elements which will be controlled through metallurgical practice and those which will require a calculation for dilution. If the dilution requires more metal to be added than is possible or practical, the program will display a warning message and compute a minimum “pour-off” weight.

The TAP program only considers materials that you have indicated are available for use during the intermediate or final additions phase of the heat/charge. The TAP program differs from the Least Cost Charge Design (MIX) program in that it begins with a determined “bath weight” with a specific chemistry to achieve.

An important feature of TAP is the ability to specify a minimum and/or maximum tap weight required, which can improve melting yields and reduce scrap returns.

TAP was designed to interface with various spectrometers, so manual entry of the preliminary test results is usually not necessary.

The TAP program incorporates all of the resolving features of the MIX program, including the ability to change your working aims. Often by changing your aims, especially the upper limit, you are able to reduce the total alloy additions required due to unnecessary dilution. You can also lower the aims if you expect an “elemental pickup” from the previous heat/charge.

There is no limit to the number of times you can resolve the solution before accepting the calculation. When a solution meets all physical, chemical, and operational requirements, TAP can reserve the materials and quantities, excluding them from further consideration.

TAP contains numerous setup options to customize the procedural flow of the program for your particular operating environment. Provisions are available for calculating optimum unit weight solutions as well as metric solutions.

The TAP program is a powerful tool that is very easy to operate and contains numerous “help” facilities for inexperienced users. TAP reflects over 20 years of refinements and improvements to meet most every client’s needs.
