Our Management

The Kalipur Wire Industries is led by a team of highly qualified and experienced people. A wide exposure and deep understanding of the industry gives an insight into the needs of the changing market, our mantra of staying ahead. The group is lead by Mr. C. C. Ghosh, who is a highly experienced and qualified professional. He takes keen interest by participating as panel member of various wire manufacturing units, involving himself from the inception stage upto the completion and helps in establishing and organising the units with his vast experience in the field. He has developed various prototype machines which are performing efficiently at various wire units. He developed various machines for drawing ferrous and non-ferrous wires. Developed on-line wire drawing plant for 32 mm wire rod indigenously for the first time in India. He also has the credit of carrying developmental work in the machinery building for drawing PC Wires, CO2 Wire, Resistance Wire, Stainless Wire, High Carbon Wire and other categories of non- ferrous wire with very fine gauge.

Formulas

Our designing team uses various wire drawing formulas for designing a variety of wires with our wire drawing machines such as weight / length relationship formula, surface area formula, zinc coating formula and formula for reduction in area



Formula

FORMULA ONE FORMULA TWO
Weight / Length Relationship:

The weight per foot of wire is :
Formula


Example : The Weight per foot os .090" wire is :
Formula
Formula


The length per lb of wire is:
Formula

Where:
w = weight per foot (lbs/ft)
d = wire diameter(inch)
L = length per lb (ft/lb)

Example : The length per lb of .090" wire is:
Formula

* Surface Area:
The surface area of one foot of wire is:
(4) a = X 0.090 / 12 = 0.0236 ft2/ft

The surface area of one lb of wire is :
(5) a/w = 1 / (36 X d X y)

Where:
a = surface area of one foot of wire (ft2/ft)
a/w = surface area of one lb of wire (ft2/lb)
d = wire diameter (inch)
w = weight of one foot of wire (lb/ft)
y = specific weight (for steel, 0.283 lbs/in3)

Example : The surface are of one lb of 0.090" diameter wire is :

a/w = 1 / (36 X 0.090 X 0.2836) = 1.088 ft2lb

* Refer to Page 369, Volume 2, Steel Wire Handbook
ZINC COATING

The Percent zinc coating on d" diameter wire coated with coz/ft2zinc is:
Formula

Example : for 0.090" diameter wire coated 0.3 oz/ft2 :

Formula


The weight of zinc on d" diameter wire coated with p% zinc is :
Formula


Where :
p% = weight percent of zinc(%)
c = zinc coating weight (oz/ft2)
d = wire diameter(inch)

Formula

Reduction in Area:

Step reduction, drawing wire from di-1to di
(8) Formula

Examples :drawing from step 3 to step 4:

r4[1-(0.090/0.102)2] X 100

drawing 0.102" wire to 090"
r = [1-(0.090/0.102)2 X 100 = 22.15%
Total Reduction, drawing from d0 to di

(9) Formula


Example:Drawing 7/32" rod 25% reduction:

Formula

Example:Drawing 7/32" rod 25% reduction:

Formula


Given the small diameter, the large diameter is:
