The TMPTC met 6–7 October 2015, Niagara Falls, Ont., Canada. The TMPTC’s AISTech 2017 Call for Papers topic was finalized.
The outline of a Tinplate Mill Roundup was established, with Dave White volunteering to take the lead in finalizing it before circulation to all the mills for completion.
The following individuals gave technical presentations:

  • Jacko Pijper of Magneto Special Anodes explained various titanium and tin anodes. He discussed the process of preparing anodes, including chemical etching, alcohol application, stove activation, handling and storage.

  • Greg Gutmann of ISRA Vision gave a technical overview of surface inspection solutions, including the differences between area scan and line scan to find strip defects and the different fields of view. 

  • Harve Anderson of Rotadyne discussed what it means to have roller reliability by tracking each individual roll’s usage. 

  • Matt Hanley of Vail Rubber explained the various spray weld methods being used today.

Meeting Highlights:
David White shared his vision for the TMPTC: focus on benefits related to the operators running  and maintaining equipment on the shop floor in a “bottom-up,  grassroots” movement. His hope is to make meeting content pragmatic and practical. Tactics to meet this goal include focusing on quality issues first.

Tinplate Mill Products Technology Committee (TMPTC) met on 3 December 2014. Of the 16 TMPTC members that attended the meeting, 10 represented tin mills. Rich Clausius of ArcelorMittal gave a presentation on the non-chromated passivation project. Dwain Hultberg of Ohio Coatings gave a presentation on the novel method to quantify the amount of haze (tin dust, smudge) on bright reflowed tinplate. He described some of the areas on the Ohio Coatings line that have been found to cause the haze, which include the grounding rolls and delivery tower rolls. Hultberg then presented a galvanostatic method to measure chrome passivation films.
