Question

The material obtained at the end of the shingling process is called as ________

(a) Flux

(b) Slag

(c) Bloom

(d) Fuse

I have been asked this question in an interview for job.

This intriguing question originated from Ferrous Metals topic in chapter Air Conditioning, Thermal Insulation, Stones & Ferrous Metals of Construction & Building Materials

Answer 1

Correct choice is (c) Bloom

The best I can explain: The process of shingling is used to remove the slag contained in the puddle balls. The material obtained at the end of the shingling process is called bloom. The bloom is then passed through grooved rollers to order to obtain flat bars which indicate wrought iron of poor quality.
