摘要： Continuously hot dip aluminum coated ferritic chromium alloy steel strip. After the steel has been given a pretreatment to remove surface contaminants, the steel is protected in a hydrogen atmosphere until it is passed into the molten aluminum coating metal. The coating metal readily wets the steel surface to prevent uncoated areas or pin holes in the coating layer.

摘要： The application discloses a method of terne coating, and a terne coated product, wherein the tin content of the terne is substantially lower than in conventional terne, without the need for other alloying elements in substitution for tin, such as zinc, antimony, silver, and phosphorus. The tin content of the terne bath is lowered below conventional percentages, to between about 2% and about 6.5% and the terne coated product, upon emerging from the coating bath, is jet finished. Such a terne coat has improved solderability and appearance with no change in pinhole frequency. Coating weight control is easier than with a terne coat having 7% or more tin in the bath.
摘要翻译：本申请公开了一种泰尔涂层方法和泰尔涂层产品，其中燕麦的锡含量基本上低于常规燕麦，而不需要其它合金元素代替锡，例如锌，锑，银，和磷。泰诺浴的锡含量低于常规百分比，降至约2％至约6.5％之间，而从涂层浴出来时，泰恩涂层产品喷射完成。这种Terne涂层具有改善的可焊性和外观，针孔频率没有变化。涂层重量控制比在浴中具有7％或更多锡的Terne涂层更容易。

摘要： A method of preparing the surfaces of steel strip and sheet stock for fluxless hot dip coating with molten metal by passing the stock through a first heating zone containing the hot gaseous products of combustion of a sulfur-bearing gaseous fuel with air, continuing the heating in a further heating zone, and cooling the stock approximately to the temperature of the molten coating metal in a reducing atmosphere. The radiant energy absorptivity of the stock is increased by forming a visible sulfur and oxygen rich layer thereon in the first heating zone and preserving the layer throughout the further heating zone. Coke oven gas may be used as fuel in the first heating zone.

摘要： A method of preparing carbon steel strip and sheet for hot dip metallic coating in a Selas-type direct-fired furnace, wherein the atmosphere in the furnace is controlled to contain from about 3% oxygen to about 2% excess combustibles by volume, thereby forming a thin iron oxide film on the carbon steel surfaces. The strip and sheet is then heated in a subsequent furnace containing at least 5% hydrogen by volume at a temperature sufficient to reduce the oxide film, viz., at least about 675.degree. C. The direct-fired furnace is preferably operated at stoichiometrically equivalent fuel:air ratios.
