One of the four major varieties of steel (plate, pipe, profile and wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (section steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc; The latter refers to I-beam, channel steel, rail, window frame steel, bending section steel, etc.

精密扁鋼生產工藝扁鋼精整機的工作原理是將冷態扁鋼毛壞用兩組上下交錯布置的校平輪對厚度方向進行預校平和更終校平；

The working principle of pre leveling and pre leveling the thickness of the flat steel in the upper and lower cold direction of the whole machine is the process of pre leveling the flat steel in the upper and lower cold direction;

用一對相對布置的精整輪對其寬度方向進行擠壓，使寬度被壓縮而達到預期的參數，其壓縮量可調；

A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable;

用5支交錯布置的校直輪對其寬度方面進行校直.。此系統主要由控制箱、精整壓輥、預校平單元、精整單元、校直單元組成。

Straighten the width with 5 staggered straightening wheels. The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.

鍍鋅扁鋼什么意思?

What does galvanized flat steel mean?

“-”是扁鋼的代號，40為型鋼寬度、4為型鋼厚度、單位通用mm。

"-" is the code of flat steel, 40 is the width of section steel, 4 is the thickness of section steel, and the unit is mm.

扁鋼，是指寬12-、厚4-、截面為長方形并稍帶鈍邊的鋼材。扁鋼可以是成品鋼材，也可以做焊管的坯料和疊軋薄板用的薄板坯。主要用途：扁鋼作為成材可用于制箍鐵、工具及機械零件，建筑上用作房架結構件、扶梯。

Flat steel refers to steel with a width of 12 -, a thickness of 4 -, a rectangular section and a slightly blunt edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate. Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings.

扁鐵產品的優點：

Advantages of flat iron products:

1、扁鋼采用負偏差軋制，但按實際重量交貨，利用率較鋼板提高1～5個百分點。

1. Flat steel is rolled with negative deviation, but delivered according to the actual weight, and the utilization rate is 1 ~ 5 percentage points higher than that of steel plate.

2、扁鋼可以按用戶需求，定厚、定寬、定長生產，為用戶減少了切割，并節省工序，降低了人工、材料的消耗，同時也減少了原材料的加工損耗，省時、省力、省料。產品已用于鋼結構制造業、機械制造業、汽車工業、礦山機械、起重機械及其它產業用材。

2. Flat steel can be produced with fixed thickness, width and length according to the needs of users, which reduces cutting, saves processes, reduces the consumption of labor and materials, reduces the processing loss of raw materials, and saves time, labor and materials. The products have been used in steel structure manufacturing, machinery manufacturing, automobile industry, mining machinery, hoisting machinery and other industries.
