Title: Production of aluminum heat exchanger having excellent pitting resistance
Inventor: KUDO HAJIME
IPC: B23K101/14
Filed: 1989-02-03
Abstract: PURPOSE:To obtain the heat exchanger having excellent pitting resistance by applying a flux prepd. by mixing Zn powder and the fluoride of K and Al with a synthetic resin binder to a specific thickness on the surface of an Al (alloy) tubular material and diffusing the Zn powder at the time of a heating treatment for brazing. CONSTITUTION:A corrugated alloy fin material consisting of a brazing sheet formed by cladding an Al-Si alloy brazing filler metal on one or both surfaces of an Al alloy core material is combined with the Al (alloy) tubular material which is extrusion molded to a straight pipe shape or is bent. The synthetic resin binder of an acrylic acid or the like is mixed with the flux essentially consisting of the Zn powder and the fluoride of the K and Al, such as K3AlF6 and the mixture is applied to 10 to 300mum thickness on the surface of the Al (alloy) tubular material. The fluoride of the K and Al in the flux extremely accelerates the diffusion of the Zn powder to the surface part of the tubular material at the time of the heating treatment for brazing and the Zn penetrates deeply into the surface part of the tubular material. The Al heat exchanger exhibits the excellent pitting resistance over a long period of time even in severe corrosive environment.

IPC: F27D21/00
Filed: 1985-02-13
Abstract: PURPOSE:To predict and discriminate exactly the time when the protection of the refractory bricks of a blast furnace under operation is necessary by determining the tendency of the max. value of the measured temp. to an increase with time from the measured value of the change of said refractory bricks with time and predicting the future period when the refractory bricks are damaged.

The max. value 1 and min. value 2 are determined upon lapse of time and the tendency of the max. value to the increase with time is plotted on a logarithmic graph from the measurement data or is determined quantitatively by a method of least squares. The period when the max. value of the temp. of the refractory bricks attains the preset upper limit temp. of the refractory bricks corresponding to the required residual thickness of the refractory bricks is discriminated by using such graph for the tendency of the value 1 to the increase with time. Whether the refractory bricks are in the period requiring the protection or not is discriminated from period requiring the protection or not is discriminated from the period discriminated in the above-mentioned manner and the stable operation of the blast furnace is executed without the shutdown.
