In Out of this Furnace‚ unionism at the outset of the depression was referred to as "merciless repression." This was evident through the mere 6 percent labor force that belonged to the Unions. But with the new climate inspiring men like Dobie from Out of This Furnace and aid from the federal government in the form of the Wagner Act‚ during the 1930’s unions were able to establish themselves‚ demonstrated by 1/3 workers carrying union card by 1940.

ore – naturally occurring in the form of ferrous oxide – into pig iron. In this operation‚ a coker converts coal into coke that is then combined with iron ore in a blast furnace to produce molten pig iron. • Refining Converting pig iron into steel is called refining. The most common technology is the basic oxygen furnace (BOF) which injects oxygen into the molten metal to adjust the carbon content and reduce contaminants such as sulfur‚ nitrogen‚ and oxygen. Alloying elements needed to obtain

bonded water in the hydroxide form. Dehydration is a minimum and some pre-reduction of the ore in a rotary kiln is used to optimize the utilization of electric power for smelting operations in the electric arc furnace. Ferronickel production therefore typically uses a rotary kiln and electric furnace process. After the saprolitic ore has been sized for treatment and partially dried‚ it is fed together with a solid reductant to a rotary kiln. The kilns used in lateritic processing are fired counter-currently

In this way‚ the cost will be reduced and the appearance‚ quality and the physical indicator of the products can reach the national standards. The good product quality can improve the economic efficiency and market competition capacity of the company. Taking advantage of ash and slag‚ blast furnace slag production to produce glazed tiles has created a new way to control waste

with iron ores and fluxes (limestone) to be mixed and then pelletized in a sinter plant. At the same time‚ raw coal is processed to form coke in a coke plant and then sintered pellets along with coke are fed to a blast furnace. Hot metal is obtained at the bottom of the blast furnace above which slag floats‚ both of them are tapped out. Hot Iron metal is processed in LD1‚ LD2 and LD3 (Ladles) to lower down the carbon content to form steel‚ this constitutes the steel making step and the technique is
