本発明は片面亜鉛メッキ鋼板の合金化処理方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for alloying a single-sided galvanized steel sheet.
靜しくは合金化処理後の非メッキｒＩＨ（鉄面）の酸化
物発生を抑制することにある。The purpose of quietness is to suppress the generation of oxides on the non-plated rIH (iron surface) after alloying treatment.
片肉亜鉛メッキ鋼板（帝）は、メッキ面が亜鉛のものと
、亜鉛と鉄の合金化処理し九ものがある。Single-walled galvanized steel sheets (Tei) come in two types: one with a zinc-plated surface, and one with an alloyed surface of zinc and iron.
しかして亜鉛と鉄の合金化したものを製造する場合は、

る。However, when manufacturing an alloy of zinc and iron,
The copper strip after plating is heated for a few seconds at a temperature of 500 to 1000°C to alloy the copper strip (iron) of the original plate with zinc. Due to contact with the steel, the iron E1m (for non-plating) is oxidized and the subsequent paint adhesion is compromised, so pickling removal is recommended, and it also has drawbacks such as a longer pickling time. .
本発明は、このような欠点を有利に解決する友めなされ

に関するものでめる。The present invention has been made to advantageously solve these drawbacks69, and is characterized by introducing a single-sided galvanized steel sheet into an alloying furnace, heating and alloying it, and This article relates to a method for alloying a single-sided galvanized steel sheet, which is characterized by cooling the iron surface to 300° C. or less after leaving the furnace.

水をスグレーする方法が有利である。That is, in the present invention, piece 1iii! iii) A lead-plated steel plate (strip) is heated in an alloying furnace and then subjected to alloying treatment.It is then heated by gas combustion, etc. At this time, it dries and oxidizes, but when it leaves the alloying furnace, the high-temperature plating is removed. The steel plate (strip) comes into contact with the atmosphere and secondary scale is generated on the iron surface (non-plated surface), so it is difficult to prevent this from occurring.
As mentioned above, the iron surface is immediately cooled to below 300°C after being removed from the alloying furnace.By cooling to below 300°C, oxidation (scaling) due to contact with the atmosphere is extremely minimized. , In the subsequent pickling, a! removes the primary school generated within the ajaku r!
# on it! This is extremely advantageous as it can shorten the time required for the situation. ? If the 9I cooling temperature exceeds aooc, scale will occur rapidly, which is undesirable.Next, as a cooling method, gas, air/water temperature, or water cooling can be used, but
Advantageous is the method of grading the water.
