Abstract
A sinter welding flux for repairing pipe mould is proportionally prepared from Al2O3, magnesium oxide, calcium oxide, SiO2, calcium fluoride, MnFe alloy, Cr or CrFe alloy, MoFe alloy, Ni and TiFe alloy through proportional mixing, adding water, stirring, granulating, baking and sieving. Its advantages are high resistance to thermal cracking, wear and oxidizing and low linear expansibility.
Description
Technical field
The invention belongs to field of welding material, the sintered flux that particularly a kind of agent for repairing tube mould is used is used for whole built-up welding agent for repairing tube mould.
Background technology
Pipe die is the main tool that centrifugal casting machine is produced large-scale cast tube.Produce in the process of large-scale cast tube at centrifugal casting machine, pipe die is worked under hot conditions repeatedly.The pipe die of working under mal-condition like this wall within it forms a large amount of fire checks (be full of cracks) and damages, and is a kind of rapid wear material therefore, its consumption very big (every new pipe die is worth ten thousand yuan of 40-50).In order to reduce production costs, increase economic efficiency, adopt whole technique for overlaying that it is repaired, for using repeatedly.With overlaying method pipe die being carried out integral body reparation, except having the proper tools, mainly is to make overlay cladding can satisfy the job requirement of pipe die with suitable solder flux, and special-purpose sintered flux just will be arranged.
Summary of the invention
The purpose of this invention is to provide sintered flux and manufacture method thereof that a kind of agent for repairing tube mould is used.
The objective of the invention is to realize by following technical proposals.
According to the sintered flux that agent for repairing tube mould of the present invention is used, it is characterized in that being formed by following components in weight percentage:
