Appointment: protection of a surface of fusion against oxidation and formation of oxides, in the main A12O3. Improvement of a zhidkotekuchesta of fusion and mechanical properties of cast material.
Scope: metallurgical processing of fusions aluminum bronz at proizvodstvekachestvenny castings.
Aluminum bronze under adverse conditions of melting and pouring easily are oxidized with formation of refractory Al2O3 oxides which, getting to cast material, cause mass marriage on "a slate break".
Tekhnikaprimeneniya:preparat enter step by step. At the beginning together with furnace charge for reduction of its oxidation when melting. Further the mirror of fusion needs to be kept under a preparation layer. Upon termination of melting stiffened slag it is necessary to peel off. It is desirable to protect a fusion mirror in a razlivochny ladle, and to remove slag just before pouring. Temperature began reactions of a preparation 860 C.
Consumption rate: 0,2 ¸1,0 (on weight).
Appearance: light blue powder. Has no smell.
Packing: paper bags with a polyethylene layer on 25 kg.
Established period of use: 12 months.
