Portland Blast- slag Cement Furnace (ASTM C 595)

แปลว่า(Concrete Engineering) The product obtained by intimately intergrinding or an intimate and uniform blending a mixture of granulated blast furnace slag and portland-cement clinker

Blast Furnace Slag

แปลว่า(Concrete Engineering) A non-metallic waste product developed in the manufacture of pig iron, consisting basically of a mixture of lime, silica and alumina, the same oxides that make up portland cement, but not in the same proportions or forms. It is used both in the manufacture of portland blast furnace slag cement and as an aggregate for lightweight concrete.

Acid Steel

แปลว่า(english) Steel melted in a furnace with an acid bottom and lining and under a slag containing an excess of an acid substance such as silica.

Acid

แปลว่า(english) 1) A solution or liquid with a pH less than 7, 2) term applied to slags, refractors, and minerals containing a high percentage of silica.

Breakout

แปลว่า(english) An accident caused by the failure of the walls of the hearth of the furnace resulting in liquid iron or slag (or both) flowing uncontrolled out of the blast furnace.

foamed blast-furnace slag

แปลว่าตะกรันพรุน

air-cooled blast furnace slag

แปลว่าตะกรันเตาถลุงเย็นในอากาศ

Basic Steel

แปลว่า(english) Steel melted in a furnace with a basic bottom and lining and under a slag containing an excess of a basic substance such as magnesia or lime.

slag

แปลว่าขี้โลหะจากเตาลุงใช้มากในการก่อสร้างถนน และงานก่อคอนกรีต

slag cement

แปลว่าซีเมนต์ซึ่งทำขึ้นจากขี้โลหะ จากเตาหลอมเหล็ก

Blast Furnace 2

แปลว่า(english) A vertical shaft type smelting furnace in which an air blast is used, usually hot, for producing pih iron. The furnace is continuous in operation using iron ore, coke, and limestone as raw materials which are charged at the top while the molten iron and slag are collected at the bottom and are tapped out at intervals.

Basic Oxygen Furnace (BOF)

แปลว่า(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "
