摘要： A flame-retardant polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin and 0.001 to 5.0 parts by weight of at least one metal salt of an organic phosphoric acid ester represented by the following general formula [I] ##STR1## wherein R.sub.1 and R.sub.2, independently from each other, represent an alkyl or aryl group which is substituted or unsubstituted by halogen, at least one of R.sub.1 and R.sub.2 is an aryl group and when both R.sub.1 and R.sub.2 are aryl groups, they may be bonded to each other either directly or through an alkylene group or may form one fused ring, and M represents an alkali metal, and optionally 0.01 to 2.0 parts by weight of a micro-fibrous polytetrafluoroethylene.

摘要： A liner for the outlet port of a rod mill including a cylindrical body provided on the peripheral edge of an opening of the liner and projecting outwardly through the outlet port to prevent a rod from exiting the liner. The projecting length of the cylindrical body on the side close to the end portion of the barrel of the rod mill is preferably longer than that on the opposite side.

摘要： A shell structure of a heavy-load type rod mill including a barrel having an outlet port and with a plate thickness of t.sub.1, and a pair of trunnions having journals integrally formed thereon and with a plate thickness of t.sub.2, which trunnions are welded to the barrel. At the weld joining the barrel and the trunnion, the relationship between the plate thickness t.sub.1 of the barrel and the plate thickness t.sub.2 of the trunnion is t.sub.1 .ltoreq.t.sub.2 .ltoreq.2t.sub.1.

摘要： A slag disposal method for disposing of slags produced in furnaces during iron or steel making processes comprises employing the steps of magnetic sorting of masses of crude slags of a size greater than a value ranging between 300 to 500 mm obtained from the furnaces into slags rich in iron (above about 50 to 60 percent) and slags not rich in iron (below about 50 to 60 percent) and then applying a compressive force to the slags rich in iron to cause a coarse crushing and/or deformation to reduce the size and at the same time increase the iron content due to the breaking and separation of the slags from the metal. Further magnetic sorting and sieving after griding are provided to obtain concentrates having high iron content and to improve recovery efficiency.
摘要翻译： 用于处理在铁或炼钢过程中在炉中产生的炉渣的炉渣处理方法包括采用以下步骤：将从炉中获得的大于300-500mm范围内的大小的粗渣的大量分选成富含 铁（高于约50％至60％）和不富铁的炉渣（低于约50％至60％），然后对富含铁的炉渣施加压缩力，引起粗粉碎和/或变形以减小尺寸和 同时由于渣与金属的断裂和分离而增加铁含量。 提供磨削后的进一步的磁选分选和筛选以获得具有高铁含量的浓缩物并提高回收效率。
