濟南角鋼(gang)鍍鋅起到腐蝕的(de)目的(de)!

熱鍍鋅角鋼也叫熱浸鍍鋅角鋼或熱浸鋅角鋼。是將除銹后的角鋼浸入500℃左右融化的鋅液中,使角鋼表面附著鋅層,從而起到防腐的目的,適用于各種強酸、堿霧氣等強腐蝕環境中。
Hot dip galvanized angle steel is also called hot dip galvanized angle steel or hot dip galvanized angle steel. It is to immerse the angle steel after rust removal into molten zinc at about 500 ℃ to make the surface of angle steel adhere zinc layer, so as to achieve the purpose of anti-corrosion. It is suitable for various strong corrosive environments such as strong acid and alkali fog.
流程:熱鍍鋅角鋼工藝流程:角鋼酸洗→水洗→浸助鍍溶劑→烘干預熱→掛鍍→冷卻→鈍化→清洗→打磨→熱鍍鋅完工。
Process flow: hot dip galvanized angle steel process flow: angle steel pickling → water washing → dipping auxiliary plating solvent → drying and preheating → hanging plating → cooling → passivation → cleaning → polishing → hot dip galvanizing completion.
熱鍍鋅角鋼的鍍鋅層厚度均勻,可達30-50um,可靠性好,鍍鋅層與鋼材間是冶金結合,成為鋼表面的一部份,因此熱鍍鋅角鋼的鍍層持久性較為可靠。熱鍍鋅角鋼的原材料為角鋼,所以分類于角鋼相同。
The thickness of galvanized layer of hot-dip galvanized angle steel is uniform, up to 30-50um, with good reliability. The galvanized layer and steel are metallurgically combined and become a part of the steel surface. Therefore, the durability of galvanized layer of hot-dip galvanized angle steel is relatively reliable. The raw material of hot dip galvanized angle steel is angle steel, so the classification is the same as that of angle steel.

濟南角鋼的表面質量在標準中有規定,一般要求不得存在使用上有害的缺陷,如分層、結疤、裂縫等。
The surface quality of Jinan angle steel is stipulated in the standard. Generally, it is required that there should be no harmful defects in use, such as delamination, scarring, cracks, etc.
角鋼幾何形狀偏差的允許范圍在標準中也有規定,一般包括彎曲度、邊寬、邊厚、頂角、理論重量等項,并規定角鋼不得有顯著的扭轉。
The allowable range of angle steel geometry deviation is also specified in the standard, which generally includes the items of bending degree, side width, side thickness, top angle, theoretical weight, etc., and the angle steel shall not have significant torsion.
