Making out saw control model and position control model, Heavy H-beam saw control model resolve the speed and overload relation between hotsaw and cold saw, making short about the saw cycle.
The special phenomena of less or even no hydrogen flake occurrence in the hotsaw rail specimens from China plateau steel plants, because there is low hydrogen content in molten steel, are discussed.
To solve problem what hot sliced-head can depart fleetly from hot-mile product line, this paper has designed transporting device about hotsaw sliced-head by means of mechanical system design method.
