Alternatively, limestone is crushed, and kneaded with salt water and granulated, and the granules are backed to form salt fired quick lime crushed or pulverized in the slag-making size. The obtained quick lime is reacted with sulfur component or phosphoric acid component in a molten metal in a metal refining furnace so as to form a lime-based flux for promoting the generation of slag. During the granulation, Al 2 O 3 or C or magnesia may be mixed therein. Calcium/ferrite may be blended after crushing or pulverizing quick lime. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the following problem: although metal calcium is hitherto hermetically sealed in an iron vessel and is stored therein, because metal calcium has a property to react with water, particularly with water content in air, and generates hydrogen which is accumulated during storage and there is a danger of explosion caused by fire, the iron vessel is too heavy to be handled easily.SOLUTION: A coating film, for example, of a metal such as aluminum, of a synthetic resin or of sodium silicate, is formed on a surface of metal calcium to interrupt contact of metal calcium with water. In addition, metal calcium whose surface is covered in this way is put into a bag made of a polyolefin, and the mouth of the bag is hermetically sealed so as to interrupt contact with moisture.
