My heart is with the steelworkers - shopfloor and boardroom alike.
Positive AFFECT. An indication of a feeling of sympathy by the writer.
Anyone who has seen white-hot liquid steel pouring out of vats or heard red-hot metal screaming as it is rolled, hammered and cut into shape, knows steelmaking is more than just a job. It has been at the heart of industry for over a century.
Implicit (provoked) positive JUDGEMENT. Here there is plenty of language which could be seen as evaluative. It's mostly intensifying - eg white-hot, pouring, screaming, at the heart of. The point of all this does seem to be to indicate a positive regard for (a) the steel industry and/or (b), possibly steel workers. The closest the writer gets to making this evaluation explicit is with the phrase, "more than a job". But nowhere does the writer actually declare that the steel-making industry was 'vital' to the British economy (implied in "at the heart of industry") or that working in a steel plant requires strength and courage or that steel workers are committed, resilient or loyal (some or all of which may be implied by 'more than a job"). Accordingly, from my reading position, I see this as provoking a positive Judgement.
