Apparatus for inserting an expendable sensor into a basic oxygen furnace

Abstract: Improved apparatus for positioning a temperature sensor, such as an expendable immersion thermocouple and a liquidus arrest carbon device in a lance. The apparatus includes a sensor housing and a downwardly extending sensor lance connected to and communicating with the housing. The housing contains a rotatable sensor storage means, a variable-stroke sensor feeder means, and electrical means to power the variable stroke feeder means and limit its upper and lower movement. The electrical means is connected to external control circuitry which is responsive to the presence or absence of thermocouple wiring connections between the sensor and lance tip to automatically feed and position the sensor in the lance tip. A recorder is connected to the thermocouple and liquidus arrest carbon device in the lowermost sensor by means of sensor contacts wiping stationary contacts in the lance tip. A sensor positioned in the lance tip can be inserted into a ferrous bath in a refining furnace, such as a basic oxygen furnace, to determine the temperature and/or carbon content thereof.

Metal sheet and method for producing the same

Abstract: Disclosed is a method for producing a metal sheet having a full-hard central portion extending between at least two softer side edge portions of the sheet. The method comprises the step of heating the side edge portions of the sheet portions of the sheet to a higher temperature than the central portion.

Welded truck side frame

Abstract: Our invention relates to side frames for railway car trucks and more especially to truck side frames of the built up type in which the top and bottom arch bars and column members are formed of pressed sheet metal and the journal boxes each formed of cast metal, and the separate parts all secured...

Zinc coated steel sheet and strip having improved formability and surface quality and method thereof

Abstract: A method for improving the formability of zinc coated steel sheet, and the product produced therefrom. The steps of the method include applying to the zinc coating an oxalic acid solution in an amount that will form a zinc oxalate film having a coating weight in a range of s about 10 mg/ft 2 to about 100 mg/ft 2 . A lubricant is applied to the zinc oxalate film, and the lubricant is adsorbed by the zinc oxalate film to provide a lubricated zinc oxalate film that is bonded to the zinc coating. The method produces an improved zinc coated sheet product having a tightly formed lubricated coating structure resistant to galling in the die steels of a forming press. The improved zinc coated sheet product having a lubricated zinc oxalate film improves formability and reduces the coefficient of friction during the forming operations that shape the zinc coated steel sheet or strip into a finished product shape.
