一种用于窄带钢镀锌的热镀锌合金锭
摘要：
本发明提供了一种用于窄带钢热浸镀锌的一种用于窄带钢镀锌的热镀锌合金锭，其组份及其重量百分比为：铝1.2-1.4%，锑0.18-0.22%，铁≤0.004%，铅≤0.004%，铜≤0.002%，镉≤0.002%，余量为锌。本发明提供的窄带钢热镀锌合金，不但能使锌浴的流动性明显改善，并能有效减少镀锌板“挂渣”现象，降低渣率、提高镀层表面光洁度。该锌合金牌号为RZ28，锭重1000±100kg。其锭型为带有两个对称耳翘的“T”字形长方体，长方体底部为平面，耳翘上设置有吊孔，四个侧面为斜面，使长方体呈现上大下小状。
摘要（英）：

The invention provides a hot dip galvanized alloy ingot for galvanizing narrow strip steel. The hot dip galvanized alloy ingot comprises the components of, by weight, 1.2-1.4% of aluminum, 0.18-0.22%of antimony, 0.004% or the less of iron, 0.004% or the less of lead, 0.002% or the less of copper, 0.002% or the less of cadmium, and the balance zinc. According to the hot dip galvanized alloy for the narrow strip steel, fluidity of zinc bath can be obviously improved, the 'slag adhering' phenomenon of galvanized plates can be effectively reduced, the slag rate is reduced, and surface smoothnessof coatings is improved. The zinc alloy grade is RZ28, and the ingot weight is 1000 +/- 100kg, the ingot shape of the zinc alloy is of a 'T'-shaped cuboid with two symmetrical ear warps, the bottom ofthe cuboid is planar, lifting holes are formed in the ear warps, and the four sides are inclined planes, so that the cuboid is in a big-end-up shape.
