Description

TECHNICAL FIELD

[0001] The utility model relates to strip steel production technical field, concretely is a kind of aluminized silicon strip steel powder spraying temperature control device. BACKGROUND

[0002] Aluminized silicon strip steel is a kind of material plated with aluminum-silicon alloy on the surface of strip steel, with excellent high-temperature resistance, corrosion resistance and oxidation resistance. Main application fields include: automobile industry: used for manufacturing exhaust pipes, mufflers and other high-temperature components. Home appliance industry: used for manufacturing ovens, microwave ovens and other heat-resistant components. Building industry: used for manufacturing roof, wall and other weather-resistant materials. Market demand: with the rapid development of automobile, home appliance and building industry, the demand for aluminized silicon strip steel is increasing. Users have higher and higher performance requirements for aluminized silicon strip steel, especially the uniformity, adhesion and surface quality of the plating layer.

[0003] Before plating the strip steel, it is necessary to spray anti-oxidation powder on the surface of the strip steel to prevent the strip steel from oxidizing during the subsequent high-temperature hot-dip plating process. Spraying plating aid powder improves the adhesion of the plating layer to the substrate and improves the uniformity and adhesion of the plating layer.

[0004] The temperature of the surface of the strip steel has a great influence on the anti-oxidation powder and the plating aid powder. If the temperature is too low (<200℃): the powder cannot be fully softened, the adhesion effect is poor, and the powder distribution may be uneven. The anti-oxidation or plating effect is not good, which affects the quality of the subsequent plating layer. If the temperature is too high (>400℃): the powder may be over-melted or burned, resulting in powder failure. The surface of the strip steel may be oxidized, affecting the adhesion of the plating layer. INVENTION CONTENTS
