摘要： A method of forming a ridge around the outer circumference of a spigot formed at an end of a pipe. A ring having a certain wall thickness in its radial direction and formed with a peripheral groove on its outer circumference is placed around the outer circumference of the spigot. Then molten metal is poured into the peripheral groove, so that the bottom of the peripheral groove and the surface of the spigot are melted, thus joining the ring and spigot together.

摘要： A cast iron pipe surface-modified for preventing corrosion and a method of modifying the pipe surface for corrosion prevention. A corrosion preventive coating is formed on the surface of the iron material of the pipe. The corrosion preventive coating is made up of an aluminum alloy containing not less than 5 wt % but not more than 25 wt % of Mn, the remainder being Al, the aluminum alloy being such that the manganese is present as a supersaturated solid solution in an aluminum phase. The corrosion preventive coating is formed by thermally spraying a quenched aluminum alloy of the above noted composition onto the surface of the iron material of the pipe.

摘要： A method for fixing a stopper ring to the outer periphery of the spigot of a cast iron pipe for preventing separation of the pipe from another pipe. A single or plural annular grooves are formed on the inner periphery of the stopper ring, and a brazing filler material is fitted in the annular groove. The stopper ring with the annular groove in which is fitted the brazing filler material is fitted on the spigot of the pipe. Subsequently, the pipe is ferritically annealed and the stopper ring is simultaneously brazed to the spigot by the heat of annealing.
摘要翻译：一种将止动环固定到铸铁管的套管的外周的方法，用于防止管道与另一管道分离。在止动环的内周上形成单个或多个环形槽，并且将钎料填充在环形槽中。其中装有钎料的环形槽的止动环安装在管的插口上。随后，管道被铁氧体退火，并且通过退火热同时将塞环钎焊到插口。

摘要： A teeming trough for pouring molten metal into a mold. Cooling water jackets are formed at both sides of a horizontal body for molten metal teeming. Valves for adjusting cooling water feeds are disposed in cooling water feed paths for supplying cooling water into respective water cooling jackets. A lateral bend of the body at the forward end thereof is detected by a suitable sensor. The valves are controlled on the basis of the result of the sensor detection so that the balance between cooling water feeds to the water cooling jackets may be varied whereby a bend of the body can be corrected.
摘要翻译：用于将熔融金属浇注到模具中的浇注槽。冷却水套形成在水平体的两侧用于熔融金属浇注。用于调节冷却水进料的阀设置在用于将冷却水供应到各个水冷套中的冷却水供给路径中。身体在其前端的横向弯曲由适当的传感器检测。基于传感器检测的结果来控制阀门，从而可以改变进入水冷套管的冷却水之间的平衡，从而可以校正身体的弯曲。
