    摘要: A high strength cold rolled strip having excellent deep drawability and resistance to deterioration by natural aging and to planar cracking and useful for motor vehicles, is produced by hot rolling a steel slab comprising0.008-0.020% by weight of C,0.01-0.45% by weight of Mn,0.05-0.10% by weight of P,0.005-0.050% by weight of acid-soluble Al,and the balance consisting of Fe and unavoidable impurities in which N is limited to a content of 40 ppm or less, at a temperature of 1200.degree. C. or less but not lower than the Ar.sub.3 point of the steel slab; by cold rolling the resultant steel strip at a rolling reduction of 65% or more; by continuously annealing the cold rolled steel strip at a temperature of from 700.degree. to 900.degree. C. for 20 seconds to 3 minutes; by cooling the steel strip at a cooling rate of 5.degree. C./sec or more; by overaging the annealed steel strip at a temperature of from 320.degree. to 450.degree. C. for 1 to 10 minutes; by cooling said overaged steel strip to the ambient temperature, and, finally; by temper-rolling the cooled steel strip at the ambient temperature.

    摘要: A conventional appliance monitoring apparatus handles only the amount of gas used and security information for the case of a gas cutoff and can not address social needs for a desire to obtain information about influence (e.g., an amount of CO2 emission) of use of the gas combustion appliance on a terrestrial environment.A CO2 emission calculation unit 4 calculates an amount of CO2 emission based on a gas appliance used by a client output from an appliance determination unit 2, a gas flow signal thereof, and CO2 emission data pertaining to the gas appliance stored in a CO2 emission data storage unit 3. Thus, it is possible to determine the amount of CO2 emission produced by using the gas appliance by the client.

    摘要: An apparatus for continuously producing a high strength dual-phase steel strip or sheet having a chemical composition which produces a dual-phase structure composed of ferrite grains and a low temperature transformed phase when rapidly cooled from the (.alpha.+.gamma.) temperature range or from the .gamma. temperature range. The apparatus has a continuous heat treatment furnace in which the strip moves vertically and which is composed of a heating zone, a soaking zone and a cooling zone, and conventional equipment associated therewith. The cooling zone has an upper hearth roll group, a lower hearth roll group and cooling equipment for cooling the strip at a rate in the range between 1.degree. and 300.degree. C./sec. for retaining the austenite in the steel of the strip. The hearth rolls of each hearth roll group are arranged to guide the strip coming from the soaking zone up and down through the cooling zone from the inlet end to the outlet end, alternately passing around the upper hearth rolls and the lower hearth rolls. The hearth roll at the position where the strip is subjected to straining and begins to work harden as a result of the bending, and the hearth rolls subsequent to such position, have diameters such that the strain induced phase transformation of the retained austenite and consequently the work hardening of the strip when it is turned around the hearth rolls is avoided.
