Reply #30: Yeah, throwing a bucket of water on a 5,000 degree slab really helps. [View All]

I remember from working in the steel mills, they had to quench hot molds under a continuous stream of water for about 30 minutes, just to get them cool enough for steelworkers to stand close to them, while they poured more molten steel into them. And they were only about 600 degrees, before quenching. Probably less.
