(english) A semi-finished hot rolled product, rectangular in cross section, produced on a blooming mill. For iron and steel, the width is not more than twice the thickness, and the cross-sectional area is usually not less than 36 sq. in. Iron and steel blooms are sometimes made by forging.
(Concrete Engineering) The degree of plasticity of fresh concrete or mortar The normal measure of consistency is slump for concrete and flow for mortar.
(english) The process of drawing hot rolled steel through a die to impart close dimensional tolerances, a bright scale free surface and improved mechanical properties. The product is termed bright steel.
(english) In hypereutectoid steel, the temperature at which cementite goes into complete solution with austenite.
(english) A primitive furnace used for direct reduction of ore to iron.
(english) Wheels of a hard abrasive, such as Carborundum used for grinding.

Small, irregular particles of steel or iron are used as the abrasive in grit blasting, and steel or iron balls in shot blasting.
(english) A solid semi-finished round or square product that has been hot worked by forging, rolling, or extrusion. An iron or steel billet has a minimum width or thickness of 1 1/2 in. and the cross-sectional area varies from 2 1/4 to 36 sq. in. For nonferrous metals, it may also be a casting suitable for finished or semi-finished rolling or for extrusion.
