Apparatus for detecting cut-edge flaws in glass plates

A method for manufacturing a chromium-bearing pig iron comprises the steps of charging cold bond pellets, iron ore and coke lumps into a blast furnace from above and blowing a gas containing more than 50% oxygen therein and tuyere nose flame temperature control agent into the blast furnace through the tuyere, the cold bond pellets being comprised of powdered chromium ore and powdered coke as principal feed materials. The cold bond pellets are manufactured by performing a mixing, a pelletizing and a curing step. The tuyere nose flame temperature control agent is a top gas, steam, water or CO.sub.2, which is used to control the flame temperature to 2000.degree. to 2900.degree. C.
