Abstract

A process for producing grain oriented electromagnetic silicon steel. The process includes the steps of: preparing a melt of silicon steel having, by weight, from 2. 5 to 4. 0% silicon; casting the steel; hot rolling the steel; cold rolling the steel; decarburizing the steel; applying a substantially non-reactive aluminum hydroxide coating to the steel; and final texture annealing the steel. The annealed steel being characterized by a substantially uniform metallic surface.

Abstract

A process for producing electromagnetic silicon steel having a cube-on-edge orientation and a permeability of at least 1870 (G/O. sub. e) at 10 oersteds. The process includes the steps of: preparing a melt of silicon steel containing from 0. 02 to 0. 06% carbon, from 0. 0006 to 0. 0080% boron, up to 0. 0100% nitrogen, no more than 0. 008% aluminum and from 2. 5 to 4. 0% silicon; casting said steel; hot rolling said steel; cold rolling said steel; decarburizing said steel; applying a refractory oxide coating containing both boron and an oxide less stable than SiO. sub. 2 at temperatures up to 2150. degree. F; and final texture annealing said steel.

Abstract

Disclosed is an apparatus for exchanging heat with liquid material and particularly liquid material under superatmospheric pressure. A preferred embodiment of the apparatus comprises a pressure vessel for holding a body of the liquid material, and having an inlet and an outlet for the liquid material. Inside the vessel is an integral tube assembly for conducting heat exchange fluid into, through and out of a body of the liquid material in the vessel. The tube assembly comprises a heat exchange fluid feed header, a heat exchange fluid discharge header, and a plurality of heat transfer tubes from the feed header to the discharge header. In a preferred embodiment of the apparatus, the headers are coaxially aligned with a normally vertical axis, and are vertically spaced apart. The headers are joined to conduits passing through the top and bottom of the vessel. These conduits in combination with the vessel support the tube assembly.
