Apparatuses and processes for evaluating degradation and potential failure of components in an industrial heat treatment system include means and steps for establishing process settings for a baseline process cycle, collecting sensor data for at least one non-process control performance parameter during the baseline process cycle to establish a set of benchmark performance data, performing a calibration process cycle using the established process settings and collecting sensor data for the at least one non-process control performance parameter to establish a set of calibration performance data, and comparing the calibration performance data to the benchmark performance data.

A method for making a metal material composite includes: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling.

A steel strip annealing furnace humidification system includes a furnace, a water-injecting system, and a control system. The furnace has a heating region and a soaking region. The water-injecting system is configured to directly feed a liquid into the furnace. The control system is in communication with the water-injecting system to control the feed of liquid into the furnace based on a measured dew point associated with an interior of the furnace.

The transverse flux induction heating device allows an alternating magnetic field to intersect the sheet face of a conductive sheet which is conveyed in one direction, thereby inductively heating the conductive sheet. The transverse flux induction heating device includes a heating coil disposed such that a coil face faces the sheet face of the conductive sheet; a core around which the heating coil is coiled; and a shielding plate formed of a conductor and disposed between the core and a side end portion in a direction perpendicular to the conveyance direction of the conductive sheet, wherein the shielding plate has a protruded portion, and the side surface of the protruded portion represents a closed loop when viewed from a direction perpendicular to the coil face.

A solid steel flywheel rotor having improved material properties offers improved energy storage at reduced cost. A process for manufacturing the rotor is also provided.

This invention provides a magnesium laminate material with high heat radiation performance, reduced weight, higher strength, and excellent molding processability. Such metal laminate material has a three-layer-structure of a first stainless steel layer, a magnesium layer and a second stainless steel layer, wherein tensile strength (TS) is 200 to 430 MPa, elongation (EL) is 10% or more, and the surface hardness (Hv) of the first stainless steel layer and the second stainless steel layer is 300 or less.

The invention relates to a heat treatment system, in particular a roller hearth furnace. The heat treatment system comprises a useful space having a first area with a width B1 and a second area with a width B2, wherein the rollers are arranged in the first area, and wherein width B2 is greater than width B1. In this context, width is understood to be the dimension that is transverse to the through-flow direction of the furnace. Width B1 is thereby measured such that the rollers have a length at which, even when there is a temperature in the furnace for the heat treatment of metal components, they still have such a mechanical stability, for example, that their bending remains within acceptable tolerances, even in the loaded state. The second area of the useful space extends above the first area of the useful space, with the greater width B2, such that components with a maximum width B2, greater than width B1, can also be heat treated.

In a continuous annealing line for steel sheets comprising a heating zone, a soaking zone and a cooling zone, two or more induction heating devices are arranged in series in a front half part of the heating zone, and a heating stop region of 130 m in length or a slow heating region having a heating rate of more than 0 C./s but not more than 10 C./s is provided in a temperature zone that the temperature of the steel sheet between two or more induction heating devices is 250 C. to 600 C. Even if the steel sheet is rapidly heated at a heating rate of not less than 50 C./s with such a rapid heating apparatus of the heating zone, the temperature distribution in the steel sheet is uniformized to realize the quality improvement of steel sheet shape or magnetic properties and so on.

The present invention relates to a method for producing a magnetic substrate for an encoder scale. The method comprising the step of mechanically working the substrate, wherein the substrate is cooled prior to the mechanical working step. In one embodiment, a stainless steel substrate is used. The stainless steel may comprise an austenite (non-magnetic) phase and a martensite (magnetic) phase. Mechanically working and cooling in this manner increases the amount of magnetic (martensite) phase material that is formed, thereby improving the magnetic contrast when non-magnetic (austenite) marking are subsequently formed on the substrate by laser marking.
