Abstract
PURPOSE: To evenly disperse B4C over the entire length of the inside surface of a centrifugally cast pipe and provide abrasion resistance by making combination use of fused type flux composed primarily of the specific amounts of SiO2, MnO, CaO, Al203 and MgO in charging B4C power (granular) material to the inside surface of the pipe at the casting of said pipe.
CONSTITUTION: At the time of charging B4C powder (granular) material to the inside surface of a centrifugally cast pipe in order to harden its inside surface at the time of casting the same, the undermentioned fused flux is used in combination. Namely, the composition composed primarily of SiO2; 20 to 50%, MnO; 10 to 30%, CaO; 10 to 25% and Al203 and MgO respectively 1 to 10%. This method causes the hardened layer uniform over the entire length of the inside surface of the pipe to be formed and enables the high-quality centrifugally cast pipe free from any defects such as shrinkage and other to be obtained. Such pipes are used for various land pipes, inboard pipes or slurry transport pipes.
