Remarks:
1. Max shearing size for billets & round bar is subject to material at tensile strength of ≦600Mpa. If the tensile strength is different, the max shearing size will be different. For example, if you use Q235 material for deform bar rolling, the tensile strength is ≦450Mpa, BS-800 will be able to cut 130x130mm billets… 
2. The max shearing size will be large in hot shearing. Please find example at below for BS-250

Material/Temp. 900℃ 850℃ 800℃ 750℃ 700℃
Alloy steel 130x130mm 122x122mm 115x115mm 100x100mm 94x94mm
High carbon steel 135x135mm 130x130mm 120x120mm 110x110mm 95x95mm
Low carbon steel 150x150mm 145x145mm 140x140mm 130x130mm 118x118mm

 3. The shearing quantity of reinforce (TMT) bars per cut in cold condition as below.

 The specification may be change without notice because of continuous improvement.

 Economic Analysis of Billet Shearing Machine ----Date: May 8, 2011

 It seems very cheap to hire a labor, using hammer and gas cutting for billet shearing in steel factory. Actually it is very expensive! Too much waste in material, safety accident gave factory much headache, poor cutting surface bring rolling problem, very low efficiency pulling your production leg…

 Please look how much you can save, if you use HS series shearing machines to instead of manual gas cutting for billets.

l        Material cost saved in gas cutting slot (Large slot by gas melt cutting waste cost)

Suppose the gas cutting slot: 10mm; 
Continuous casting speed: 2.3m/min;
Billet size: 150mmx150mm
Billet length: 6m
Working time per day: 12 hours
Working days per year: 300 days
Formula: C=WxQxD
C: Saved material cost
W: width of gas cutting slot = 15x15x0.1x7.85=1.77kg
Q: gas cutting times = 2.3x12x60/6=276 times/day
D: Material price (For example billet price=RMB: 4.00/kg)
C=WxQxD=1.77x276x4=RMB1954.08/day
Saved material cost of gas cutting slot per year = 1954.08x300=RMB:586224.00/year

If exchange rage between USD and RMB is 6.50, the saved cost per year, the saved material cost of gas cutting slot per year is RMB586224.00/6.50=US$:90,188.31/year

l        Consumer cost saved

Take the billet 150mmx150mmx3000mm as example for calculation:

Cutting method Acetylene Propane Coke oven gas Hydrogen Oxygen
Power consumption of cutting gas costs (RMB/ton) 2.76 1.57 1.2 1.0
Mixed oxygen cost (RMB/ton) 0.36 0.71 0.14 0
The cost of steel lose (RMB/ton, take steel scrape for calculation) 4.2 4.2 5.04 4.36
Total loss (RMB/ton) 7.32 6.48 6.38 5.36
Suppose the annual production output 200000 tons, the annual total saved cost of gas as below.
Annual total loss (RMB/year) 1464000 1296000 1276000 1072000
Annual total loss (US$/year) Exchange rate 6.50 $225230 $199385 $196308 $164923

 1. Total amount of saved cost = saved material cost of gas cutting slot + saved cost of gas
Saved more than RMB: 1,658,224.00/year (US$255111.00/year)
2. Saved working time --- Gas cutting usually take longer time. Billet shearing machine is 8 to 15 cuts per minute. It’s not only save working time, but also improved production efficiency…

It is the time to stop using 'manual gas cutting' for billets, round bar etc.
