Black Oil Tempered Spring Steel Strip (Scaleless Blue)

แปลว่า(english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back.

Bridle

แปลว่า(english) A set of rolls used to maintain tension on the strip as it goes through the line.

Bottom Roll

แปลว่า(english) Submerged roll in the pot used to keep the strip submerged in the pot.

Burr

แปลว่า(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

แปลว่า(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.

Bainite

แปลว่า(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite.

Bruise

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

breaker strip

แปลว่า(รถยนต์) ชั้นผ้าใบที่อยู่ในยางหล่อหรือยางนอก เป็นสิ่งที่ช่วยให้ยางทนทานต่อความสึกหรอ
