6, how to use bronze melting furnace melting brass?
Brass is easier to smelt and has a lower melting point.
Mainly because the zinc in the alloy deoxidizes the melt, the evaporation and boiling of zinc can get out of the hydrogen of the melt, so in the process of melting the brass, a complicated refining process is generally not required. Production practice shows that the principle of “ low temperature plus zinc ” and “block by piece plus zinc ” is adhered to when smelting brass, which can reduce the zinc melt loss while ensuring safe production.
Seven, bronze and zinc melting furnace melting increase in weight, it also can be added to increase what what?
A small amount of arsenic As can be added , the reference amount is 0.1~0.15% (mainly according to the chemical composition requirements of the grade), and a trace amount of borax can also be added at the same time, and the boron content is 0.01~0.04% of the weight of the alloy . Further control the melting temperature, typically brass melting temperature does not exceed 1100 ℃. The above is for reference.
Eight bronze phosphor bronze alloy melting furnace to melt added what effect?
The role of smelting zinc brass in the addition of phosphor bronze alloy is to increase the fluidity of the copper alloy. According to the casting experience of Rongchang sliding bearing, the copper alloy has a good fluidity after the addition of phosphor bronze, so the pores and sand holes will be less when casting. If centrifugal casting is used, the copper alloy material is better, and can produce various grades of bronze, SAE660 , SAE64 , SAE793CUAL9FE4 , CUAL10FE3, CUZN24AL6, and CUSN12.
