20080236235 | Heat-Treatment Apparatus for Steel Plate and Manufacturing Line of Steel Plate Having the Heat-Treatment Apparatus - The heat-treatment apparatus for steel plate has a plurality of transfer rolls for transferring steel plate in the horizontal direction and at least one induction-heating unit for heating the steel plate. The induction-heating unit is positioned between specified adjacent transfer rolls. At least an induction-heating unit located at the most upstream side among the induction-heating units is provided with at least one pressing roll at outlet thereof to press the steel plate from above. At least the pressing roll located at the most upstream side among the pressing rolls is positioned above and facing the transfer roll located at outlet of the induction-heating unit. Owing to the heat-treatment apparatus for the steel plate, desired heat treatment can be given to the steel plate even with the induction-heating unit without adversely affecting the travel of the steel plate. | 10-02-2008 |

20130255341 | METHOD FOR HEATING A METAL SLAB - A method for heating a metal slab being transported in a longitudinal direction (L) and having a cross-direction (T) through an industrial furnace in which the metal slab is heated and transported on a rail device from the industrial furnace for subsequent processing, includes impinging a flame from at least one direct flame impingement (DFI) burner to contact a first portion of a first surface of the metal slab in at least one location corresponding to a second position on an under side surface of the metal slab which during transporting of the metal slab through the industrial furnace constitutes a contact point between the under side surface of the metal slab and the rail device, and counteracting a temperature gradient in the metal slab arising from local cooling of the metal slab upon contact with the rail device by heating the first portion with the DFI burner. | 10-03-2013 |
20140245806 | METHOD OF PRODUCING SEAMLESS METAL PIPE - A method of producing a seamless metal pipe, which can suppress the occurrence of lamination defects, is provided. A method of producing a seamless metal pipe according to an embodiment of the present invention includes the steps of: heating a high alloy containing, by mass %, Cr: 20 to 30% and Ni: more than 22% and not more than 60% in a first heating furnace (S2); piercing-rolling the high alloy heated in the first heating furnace with a first piercing machine to produce a hollow shell (S3); heating the hollow shell in a second heating furnace (S4); and elongation-rolling the hollow shell heated in the second heating furnace with the first piercing machine or a second piercing machine which is different from the first piercing machine (S5). | 09-04-2014 |
20140250966 | Ferrous Alloy For Coining And Method For Producing The Same - A ferrous alloy is provided for coining The ferrous alloy includes a composition of: 4.00-10.80 wt % of chromium (Cr), 8.00-25.00 wt % of nickel (Ni), 3.00-6.00 wt % of copper (Cu), and a balance of iron (Fe) and incidental impurities. | 09-11-2014 |

20150332194 | METHOD AND DEVICE FOR ASSIGNING SURPLUS SLABS IN THE SLAB YARD BEFORE HOT ROLLING PROCESS - A method for assigning surplus slabs in slab yards to orders includes loading slab pre-yards of a plurality of production lines with surplus slabs, describing the assignment of the surplus slabs to the orders with a mathematical model, grouping order data and slab data based on steel grades, obtaining an assignment scheme for the surplus slabs and the orders in each group with a mixed scatter search algorithm, and assigning the surplus slabs to the orders using the assignment scheme. If a surplus slab is in a pre-yard of a production line associated with an order the surplus slab is assigned to, the slab is moved using a crane to the production line. Otherwise, the slab is moved to the pre-yard associated with the production line, and then moved using a crane to the production line. The slab is then heated and rolled by the production line. | 11-19-2015 |
