If you would like to learn more about the IRD ASSOCIATION, INC Certification Program please view the following files. If you have a pass design you would like to submit to be reviewed by the IRD ASSOCIATION, INC Certification Committee please print the application and send the application to the IRD ASSOCIATION, INC Secretary.
The purpose of the certification program is to recognize fellow members for their accomplishments and to serve as a means of accrediation to the steel industry.
A) Roll designers who are certified in (four) or more disciplines will be recognized by his colleagues as "Master of the Art of Roll Design". See also "General Considerations notes "A and C""
B) Roll designers having been certified in (three) disciplines will gain the title of "Professional Roll Designer". See also "General Considerations notes "A and B""
C) Roll designers having been certified in (two) disciplines will become a "Qualified Roll Designer".
D) Roll designers having been certified in (one) certification will become an "Associate Roll Designer".
Certification may be accomplished in one of the following manners:
1.) Submission of a pass design by the applicant which has been proven in the mill, with proper documentation signed by a responsible person in the company. The pass design may be submitted as drawings, and if available templates or slices of cobbles from passes. All work submitted to the certification board will be treated as proprietary and will be returned after the evaluation
2. Submission of a pass design with all pertinent mill information to evaluate the pass design as to its validity for the given mill. The applicant must then be prepared to present the design in the form of a technical paper at a regular IRD meeting.

The application form, along with the detailed information as described for each discipline (for the evaluation) and the appropriate fees must be delivered by mail to the "current treasurer of the IRD", who will document the fees and deliver the application to the chairman of the certification review board. To cover the cost of mailing, copying, printing and any other expenses incurred by the certification board there will be a fee of $25.00 for each discipline applied for
All (4) members of the certification review board must review each “application for certification”. Upon approval by (3) of the (4) review board members, the applicant will be presented with a signed "certification" certificate in one or more of the six disciplines applied for. The certificates will then be presented at the next business meeting. Decisions made by the review board are final and cannot be reversed by the executive board. Upon submitting proof to the "Certification Review Board", the "IRD" will certify a member in one or more of the six disciplines listed below:
1a.) Roll Pass Design for Merchant Bars. (Sizes less than 3")
a. Design for Rounds
b. Design for Angles
c. Design for Channel
d. Design for Flats
e. Design for Hex or Squares
f. Design for “T’s”
An applicant submitting a working design for any (3) of the above (5) Products may be accepted by the CERTIFICATION REVIEW BOARD for certification in this discipline. It will be required that (1) of the (3) shall be a design for Angle or Channel.
cert. page (2)
2a.) Roll Pass Design for Die Rolling (concrete reinforcement bar, studded fence post, etc.)
To become qualified under this discipline the applicant must submit one or more pass sequences demonstrating that he / she has an adequate understanding of the factors necessary to design all aspects of groove spacing required to generate single or multiple helixes, in the case of re-bar where some other end product is the design subject. The candidate shall demonstrate knowledge of the calculations necessary to provide the desired spacing for whatever periodic spacing is desired for the end product.
3a.) Roll Pass Design for Rail (Standard or Special)
The design submitted shall demonstrate that the candidate has sufficient understanding of the subject to address the significant critical aspects of rail design. In an endeavor to provide this data it is recommended that the candidate submit designs in both, the small (30#) and large (136#) ends of the spectrum.
4a.) Roll Pass Design for Structural Angles, Channels, Standard
Beams and I - Beams.
Required: The candidate must succeed in all of the following.
a. A design sequence for Structural Angles.
b. A design sequence for Structural Channels.
c. A design sequence for Structural Beams, or I - Beams.
Where the candidate for certification has not had the opportunity to design sections in all of these fields, he/she should be prepared to establish by either, a discussion paper and/or personal interview with the Certification Review Board that he/she is familiar with the critical aspects of these other shapes, and so would be capable of developing designs in these areas if so required.
cert. page (3)
5a.) Roll Pass Design for Special Sections (sections not found in the
"Association of Iron and Steel Construction" Handbook -8th Edition, 1980)
To become qualified in this discipline the candidate will be required to submit a section that is not a standard product as found in the "AISC" handbook and is being, or has been rolled successfully in a steel mill.
6a.) Roll Pass Design for Pipe or Tubing:
For this discipline the candidate will be expected to submit designs for the hot rolling process (piercing) of both small and large pipe or tubing, with sufficient written documentation to demonstrate a thorough knowledge of the processes and equipment required to produce the desired end product.
It should be appreciated that any design submitted to the Review Board for certification must include details of passes from a significant number of passes prior to the leader and finishing passes. This is to demonstrate to the Review Board that the applicant has a good and sufficient knowledge of the working of the product.
A. The philosophy of the Certification Review Board shall be: any candidate seeking certification in any of the disciplines will be certified only when the Review Board is convinced that the candidate has a sufficient knowledge of the discipline, and that he/she would be capable of producing a workable design for any product within that discipline.
B. In addition to the requirements of "A", above, any candidate applying for the designation of "Professional Roll Designer "shall have spent not less than (10) years in a situation where he/she has had opportunity to be exposed to the results of his/her designs, and the workability on the mills for which they were designed.
cert. page (4)
C. In addition to the requirements listed. Any candidate applying for the designation of "Master Roll Designer" shall have spent not less than (15) years in a situation where he/she has had opportunity to be exposed to the results of his/her designs, and the workability on the mills for which they were designed
Certification Review Board:
One Review Board member will be replaced every two years. The replacement member will be selected by the current certification review board, from those members who have been previously deemed "Master of the Art of Roll Design". Their term will begin / end at the fall "IRD" Conference on odd numbered years.
Should a review board member be unable to complete their term, the certification review board will appoint an interim replacement member.
The senior board member, will be the chairman of the review board. The chairman will be responsible for receiving and tracking each application through the certification evaluation review.
Changes to the procedures of the certification program will be submitted by the certification review board to the executive committee and acted on by the review board as soon as possible.
1) In the beginning of the certification program (1990), the Executive Board
served as the Review Board to certify the initial Certification Review
Board consisting of (4) members. These members were certified in at least (4) of the (6) disciplines, and deemed "Masters of the Art of Roll Design".
2) The review board had the authority to waive any or all of the requirements of number 1 and 2 (page 1) and use other proof for 1991 - 1992 terms.
