This technical report covers series, shunt and compound wound motors of two standard enclosure types: TENV (totally enclosed nonventilated) and TEFV (totally enclosed forced ventilation from a separate source).
|
This standard is intended to serve alloy steel chain users as a guide to loading, wear and other usage limitations in normal industrial lifting chain service.

Updated January 2021. The intent of this
report remains committed to the advancement of technologies in the design and
manufacture of laminated ladle hooks that are used primarily for lifting hot
metal ladles. Hooks rigidly attached to a spreader beam should be avoided and,
therefore, are not discussed in this Technical Report.

Hot
metal cars (a.k.a. torpedo cars, sub cars, bottle cars, Pugh cars, mixer cars)
are used to transport molten iron from the blast furnace to the steelmaking
facility. They are vital to the everyday operation of integrated steel
manufacturers. The purpose of this document is to provide guidelines for
inspection, maintenance, and repairs of Hot Metal Cars.

The current edition of this technical report addresses the entire scope of friction brakes that are spring set, including shoe, caliper disc and motor mounted plate brakes for crane applications.

AISE
Subcommittee No. 27 on New Steel Pressure-Containing Components for Blast
Furnace Installations was formed in 1974 to establish criteria for the design,
fabrication and construction of new steel pressure-containing components for
blast furnace installations. This technical report has been prepared by a
committee consisting of designers, owners and manufacturers who considered the
current technology available. It is intended to present a set of criteria for
the design, material selection, fabrication, erection, inspection and testing
of new steel pressure-containing components used in blast furnace installation.

The
intent of this report is to provide a set of criteria for the material
selection, design, fabrication, erection, inspection, testing, maintenance and
alteration of certain BOF components.

This
technical report covers the specifications for design of new ladles with
circular, oval or obround cross-sections and with welded or riveted
construction. It also addresses the selection of materials and structural
design methods for primary ladle components and also the use of high-strength
refractories to assist in obtaining optimal ladle life and minimal ladle
repair.

The 2018 edition of AIST Specification for Electrical Overhead Traveling Cranes for Steel Mill Service (Technical Report No. 6) is the 10th revision since the first AISEE General Crane Specification was published in 1910. Authored by crane owners, engineers, manufacturers and equipment suppliers, the consensus-derived technical report outlines experience-proven best practices, maintenance friendly designs, and flexible and practical options for crane applications in the steel mill and related facilities. Since its most recent update in 2005, TR-06 has gained wider acceptance in environments that demand overhead cranes operate in difficult conditions, including contributors and users from not just the steel industry, but also aluminum, shipping, and the military, among others.
Please note: this is a downloadable PDF version of TR-06. Download will be available after purchase. |

Updated for 2021, this report guides the owner
and designer through the many assumptions and parameters involved in the design
of a mill building. It suggests loads and load combinations for the design of
crane runways, roof structures, floors, columns, building frames and
foundations. Information is given for investigation, earthwork and excavation
requirements, as well as revisions to vibration, foundation, soil bearing
foundation, crane rails and crane rail splices. The 2021 edition contains many
updates, including the following:
- Updated Loads and Load Combinations to
reflect current codes and design practices
- Updated provisions for Runway Girder
and Column Design.
- Revised Tolerances section to
highlight fabrication vs. erection tolerances.
- Expanded Commentary section.
- Expanded Appendix C with detail
Inspection and Upgrade recommendations.

Designed to impart experience-based techniques and repair criteria for cranes, runways and associated components to newer entrants to the crane community, the AIST Overhead Crane Maintenance, Inspection & Repair Handbook contains best practices to improve your crane safety and reliability while minimizing downtime and expense.
Please note: This is the e-book
version of the AIST Overhead Crane Maintenance, Inspection & Repair
Handbook.
