Steel sheets, widely used in thousands of products, are produced Irorn slabs from a slabbing mill, continuous casting machine, or pressure-poured molils. These pieces are hot-rolled in a hoi strip mill, descaled bv pickling in an acid solution, and then cold-rolled and tempered m a cold-reduction and temper mill. Tlte cold-tolled snip may he marketed in coil form, or carried to a side-trimming and sheet shearing line, where it is customized lor speeilie user needs. 

The effect of ball milling is similar in all cases. Within the first 10 min of milling, the 002 reflection is considerably broadened and appears slightly shifted to a smaller angle. This apparent shift is probably the result of the superposition of the broadened 002 peak upon the rising, broad, amorphous peak which centers about 18.5° (2 ). As ball milling continues, the crystalline characteristics decrease and the amorphous characteristics increase. After about 1 hr of milling time, the crystalline characteristics of all the cellulosic materials have disappeared.

Milled Glass Filler - Milled glass fdlers are made by hammer-milling continuous glass strands. Used as anticrazing reinforcing fdlers for adhesives and in plastics. Also called milled glass fiber. 

In the first step isothiocyanates were prepared by the procedure described above, and then without isolation 1 equiv. of second amine was added and milling continued. Upon completion, treatment of reaction mixture with aqueous hydrochloric add and filtration afforded unsymmetrical products in high yields (entries 10-13).
