Apparatus and method for replacing a bull gear on a trunnion

Abstract: An apparatus for installing a new bull gear onto a trunnion shaft of a BOF, the apparatus comprising a first stop removably attached to the end face of a turnnion shaft, a gear press shaft extending through an aperture within the first stop means, the gear press shaft having a first end portion with an enlarged segment inserted into a recess provided within the trunnion shaft, a second stop adjustably attached to a second end portion of the gear press shaft, a gear press plate removably attached to the gear and encircling the gear press shaft between the first and second stops and a jack means located between the gear press plate and the second stop.

Method for increasing the wet bulk density of coking coals

Abstract: A method for increasing the wet bulk density of coking coal charges for code ovens which charges contain at least about 6 and as much as 13 weight percent moisture, to an optimum level of between about 47 and 50 pounds per cubic foot (753 to 801 kg per cubic meter) and for controlling and maintaining the bulk density at such optimum levels, the method including: (a) forming a 5 to 20 weight percent aqueous dispersion of a surfactant having a desired viscosity, and (b) applying a quantity of the aqueous dispersion to a quantity of coal equivalent to between about 0.5 and 2.5 pounds (0.227 and 1.135 kg) of surfactant per ton (907.2 kg) of coal, the surfactant being an alkylphenoxypoly (ethyleneoxy) ethanol having a general formula: ##STR1## where R is an alkyl group having between about 8 and 12 carbon atoms, and n is an integer between 2 and 30, and is characterized by an HLB number in the range of about 4 and 18.
