Copper Alloy Castings Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pouring time = Empirical constant 2*(Mass of casting)^(1/3)
t_pt = K₂*(W)^(1/3)
This formula uses 3 Variables

Variables Used

Pouring time - (Measured in Second) - Pouring time is the time for complete filling of a mould.
Empirical constant 2 - Empirical constant 2 is a constant whose value is to be determined by experiments or using certain tables.
Mass of casting - (Measured in Kilogram) - Mass of casting is the mass of casting to be prepared or required.

STEP 1: Convert Input(s) to Base Unit

Empirical constant 2: 3.31 --> No Conversion Required
Mass of casting: 36.8 Kilogram --> 36.8 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_pt = K₂*(W)^(1/3) --> 3.31*(36.8)^(1/3)

Evaluating ... ...

t_pt = 11.0097451623259

STEP 3: Convert Result to Output's Unit

11.0097451623259 Second --> No Conversion Required

FINAL ANSWER

11.0097451623259 ≈ 11.00975 Second <-- Pouring time

What is pouring time?

The time for complete filling of a mould is termed pouring time, is a very important criterion for design.Too long a pouring time requires a higher pouring temperature and too less a pouring time means turbulent flow in the mould, which makes the casting defect-prone. There is thus an optimum pouring time for any given casting.
The pouring time depends on the casting materials, complexity of the casting, section thickness and casting size. The various relations used are not theoretically obtained but established generally by the practice at various foundries and by experimenters.

What values can k take?

For Top gating k=1.30,
For Bottom gating k=1.80,
For Brass k=1.90,
For Tin bronze k=2.80.
