WebThe simplest way to solidify liquid steel is to pour it into heavy, thick-walled iron ingot molds, which stand on stout iron plates called stools. During and after pouring, the walls and bottom of the mold extract heat from the melt, and a solid shell forms, growing approximately with the square root of time multiplied by a constant. The value of the constant depends on … WebAfter hot-rolled seamless steel tubes, the grain refinement of steel, the ingot destroy the cast structure, eliminate defects and microstructure of the resulting dense PIPE, improved mechanical properties. Air bubbles present before the steel pipe, cracks and loose, after hot rolling at high temperature and pressure will be welded together.
