Industry Code: 29100
This industry produces raw steel products such as plate steel, reinforcing bar, rods, angle and channel iron and steel balls. Businesses in this industry are generally referred to as "rolling mills".
Operation Details:
Rolling mills are major users of recycled steel materials such as cars and appliances. Scrap metal plus additives are melted in large electric carbon arc furnaces holding up to 80 tons at temperatures near 2900 degrees F. The molten steel is poured into a lare ladle and elevated to a tower or Concast. A lever releases a plug in the bottom of the ladle and the molten steel pours into another receptacle called a Tundish that has two holes in the bottom. As the steel product flows out it follows two channels almost straight down, then bends to a horizontal position at the bottom and moves along a conveyor. The resulting billets of steel are stockpiled in the yard to cool.
The billets are reheated in electric ovens, after which the hot steel goes automatically through a series of rollers to gradually reduce the thickness and lengthen the steel for reinforcing bars. For angle iron, the steel is pushed through a mold as the last step. As the steel goes through each roller, it is sprayed with water to help temper it. After going through a cooling bed, the steel is cut to length, picked up by crane, and stored. In the case of steel balls, the rod is cut up into 2" pieces and fed to a press that pressed on all sides to form a ball.
Underwriting Considerations:
As of 1998, there exists only one business in Alberta that manufactures raw steel.
Iron and steel foundries are not nearly as large in size and scope of operations, and are typically much more labor intensive with more forming and pouring batch processes. Iron and steel foundries are classified in industry 29102.
Businesses that fabricate steel products using processes of cutting, bending, welding, etc. are classified elsewhere in this rate group.
Premium Rate History:
Activities:
Steel - Mfg (excl. foundry)
Rate Group History:
This industry was placed in the current rate group effective 1999 to effect statistical credibility for the industry, and in recognition of comparable and similar activities and processes in cutting and handling steel.
