Burn

(english) 1) Process of cutting metal by a stream of fuel and oxygen, 2) to permanently damage a metal or alloy by heating to cause either incipient melting or intergranular oxidation.

Burr

(english) The very subtle ridge on the edge of strip steel left by cutting operations such as slitting, trimming, shearing, or blanking. For example, as a steel processor trims the sides of the sheet steel parallel or cuts a sheet of steel into strips, its edges will bend with the direction of the cut.

Breaker

(english) Uncoiler rolls through which the strip passes; composed of a mandrel and leveling rolls which unwind the strip prior to processing through the Pickler. Breaker rolls assist in breaking up the Hot Mill surface scale.

Influent

(Environmental Engineering) The fluid entering a system, process, tank, etc. An effluent from one process can be an influent to another process. See effluent.

Object-oriented

(Software Engineering) an approach to software development that makes use of a classification approach and packages data and processing together

Refuse derived fuel (RDF)

(Environmental Engineering) A fuel derived from the combustible portion of municipal solid waste. The fuel is often processed into small briquettes, similar in size to charcoal.

Bruise

(english) A mark transferred to the strip surface from a defective process roll. Similar to dent or punchmark.

Acid Process 2

(english) A steel making method using an acid refractory-lined (usually silica) furnace. Neither sulfur or phosphorus is removed.

Batch Anneal

(english) The process by which a large, stationary stack of steel coils (4 coils high) is subjected to a long heat-treating cycle. This process enables the cold-rolled sheet to fully recrystallize into the softest possible product conforming to customer specifications. Controlling the recrystallization process makes a fine-grained microstructure easy to obtain, and minimizes the tendencies for retention of directional properties of the rolled steel which could produce undesirable shapes in the stamping of a cylindrical part such as a can. Also see Anneal and Continuous Anneal.

Base Metal

(english) (1) The metal present in the largest proportion in an alloy; (2) the metal to be brazed, cut or welded; (3) after welding the part of the metal that was not melted during the process.

wet process

ระบบเปียก (ในการทำเสาเข็มเจาะ)

Bed-In

(english) Method whereby drag may be rammed in the pit or flask without necessity of rolling over. Process used in production of heavy castings.
