摘要： PURPOSE:To change the direction of a plated steel strip of high temp. in noncontact by arranging plural electromagnets in such a manner that the shape of the sucking face against the steel strip is formed into a circular-arc one, controlling an exciting current and floating the steel strip up to a certain place by a magnetic force. CONSTITUTION:Electromagnets 11a to 11c are arranged in a curcular-arc state against a steel strip 1. Sensors 12a to 12c measure the distance between the electromagnets 11a to 11c and the steel strip 1 to control an exciting current and to float the steel strip 1 up to a certain place by a magnetic force. An auxiliary roll 13 is needless in the process of ordinary operation, but it is used in the case of sheet passing in the initial stage or in the case of an accident at the time of power failure. The progressing direction of the plated steel strip 1 of high temp. can be changed in noncontact.

摘要： PURPOSE:To control an end point temp. at a high cooling rate with good accuracy and to reduce the cycle for annealing by immersing a steel strip prior to entrance to a heating zone and after slow cooling into a molten medium and maintaining the specified temp. of the steel strip. CONSTITUTION:A molten medium vessel 5 contg. molten Pb, etc. is provided in front of a heating zone 6 in continuous annealing and a cold-rolled steel sheet prior to entrance into a heating zone 6 is immersed in and passed through the medium by which the steel sheet is preheated. The steel sheet is then passed through the heating zone 6, a soaking zone 7 and a slow cooling zone 7a for primary cooling and is then immersed in and passed through a vessel 9 for the molten medium having the common compsn. as the compsn. of the molten medium used in the stage of preheating, by which the steel sheet is temporarily cooled down to the overaging temp. The steel sheet is then passed through an overaging zone 10 and a secondary cooling zone 11. The steel strip is maintained quickly at the bath temp. after the immersion by using such molten medium, by which the rate of heating and cooling is improved.

摘要： PURPOSE:To expedite the response of strip temp. by performing forcing in order to correct the calculated value of the rate of transfer of heat between hearth rolls and the strip at the changing of the target temp. and the like of the heating or cooling furnace of a continuous annealing furnace. CONSTITUTION:While a strip 1 is transferred by the revolution of hearth rolls 5 of a continuous annealing furnace 2, it is heated or cooled continuously. At the changing of the target temp., thickness, and speed of the strip 1 of the furnace outlet, the quantity of heat corresponding to the rate of heat transfer between the rolls 5 and the strip 1 is calculated, and in order to correct this, forcing is carried out by using the quantity of heating or cooling. For example, at the changing of the target temp. of the strip 1, C1 is the strip temp. at the zone inlet C2, C2' are the temps. of the rolls 5, C3, C3' are the strip temps. at the zone outlet, C4 is the flow rate of fuel when the effect of the rolls 5 is not considered, and C5 is then forcing rate of the flow rate of fuel when said effect is considered. The C2, C3 and the C2', C3' are respectively the case when the forcing is carried out and when it is not and the time for setting at the target temp. of the strip is improved from about 11min to about 1min.
