Galvanized carbon steel with stainless steel-like finish

Номер: US20120219823A1
Автор: Frederick Alan Myers
Принадлежит: AK Steel Properties Inc

A “faux stainless steel” may be produced by processing galvanized carbon steel through a temper mill using textured rolls to develop a “polished” type surface. The galvanized coating is not removed by abrasion but is compressed thereby providing a more uniform substrate than conventional polishing or brushing. The resulting strip may then be coated with an organic film to provide additional appearance and corrosion benefits including anti-fingerprint resistance.

A method for surface treating work rolls to produce isotropic textured aluminum sheet features shot-peening the surface of the working rolls that produce the sheet. The media may be steel balls, such as ball bearings or other media, such as glass or ceramic balls, depending upon the optical properties desired for the aluminum sheet, e.g., in terms of diffuseness or brightness of reflection. The various parameters of shot-peening can be varied to accommodate given properties of the roll, such as hardness and existing surface texture to achieve a given desired surface texture. A sheet surface with target properties and the work roll processing needed to produce it may be generated by computer modeling.

The method for producing a rolled Mg alloy material includes rolling a Mg alloy material with a reduction roll. The reduction roll has three or more regions in the width direction. The temperature is controlled in each of the regions so that a difference between a maximum temperature and a minimum temperature exceeds 10° C. in the width direction of a surface of the reduction roll. The rolled state in the width direction is varied by varying a difference in temperature over the width direction of the reduction roll. As a result, it is possible to produce a rolled Mg alloy material whose mechanical properties are locally different in the width direction.

A compound roll includes a sintered inner core of a first cemented carbide and at least one sintered outer sleeve of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface, wherein when the inner core and outer sleeve are assembled each joining surface contact to form a bonding interface therebetween. When the assembled, sintered inner core and outer sleeve are heated to a predetermined temperature the sintered inner core and outer sleeve are fused together at the bonding interface to form the unitary compound roll. To reduce the overall cost of the compound roll, a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to an outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll.

At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant. 1100.

To minimize the setup times in the case of a tool changeover on rolls, the movement sequences are separated into transverse movements and vertical movements using a tool changeover system and method for changeover of at least one tool disposed on a roll shaft in a working position. In one aspect, the tool changeover system includes a tool changeover rack, a vertical transport and a transverse transport. A drawing frame separate from the tool changeover rack can be transported transversely separately with reference to the tool changeover rack. The tool changeover rack has a device for connecting with the vertical transport and a tool accommodation for accommodating the tool. The drawing frame has a device for connecting with the transverse transport and a device for connecting with the tool. 1. A tool changeover system for changeover of at least one tool disposed on a roll shaft in a working position comprising:(a) a vertical transport;(b) a tool changeover rack comprising a device for connecting with the vertical transport and a tool accommodation for accommodating the at least one tool;(c) a transverse transport; and(d) a drawing frame separate from the tool changeover rack and separately transportable transversely with reference to the tool changeover rack, wherein the drawing frame comprises a device for connecting with the transverse transport and a device for connecting with the tool.2. A tool changeover system for changeover of at least one tool disposed on a roll shaft in a working position comprising:(a) a vertical transport;(b) a tool changeover rack;(c) a guide support; and(d) a changeover rack guide configured as a motion link guide between the tool changeover rack and the guide support, wherein the motion link guide comprises a guide track having an open top portion comprising a guide track opening, and wherein the guide track comprises a constant vertical track component guiding the tool changeover rack to the changeover position with reference to the ...
