什么是热轧卷板？

What is a hot-rolled coil?

热轧卷板是以板坯（主要为连铸坯）为原料，经加热后由粗轧机组及精轧机组制成带钢，从精轧最后一架轧机出来的热钢带通过层流冷却至设定温度，由卷取机卷成钢带卷，冷却后的钢带卷，根据用户的不同需求，经过不同的精整作业线（平整、矫直、横切或纵切、检验、称重、包装及标志等）加工而成为钢板、平整卷及纵切钢带产品。

Hot-rolled coil is made of slab (mainly continuous casting) and heated from coarse rolling unit and refined rolling unit. Hot steel strip from the last mill is cooled from laminar to set temperature by the coil. After cooling, the steel strip coil are processed by different finishing operation lines (leveling, straightening, transverse cutting, inspection, weighing, packaging and marking) according to different needs of the user.

热轧钢板是由一块儿板坯在经过粗轧和精轧的一道道工序后而生产的。热轧钢板以其良好的韧性，强度较高和便于加工的优良特性，成为汽车行业、建筑行业等所需要的结构钢，其中热轧卷板的其中一个的主要应用领域就是油气输送管道，巨大豪华的邮轮的船体和甲板也能看到热轧卷板的身影。

Hot-rolled steel plates are produced by a single slab after rough and carefully rolled processes.With its good toughness, high strength and easy to process, the hot-rolled steel plate has become the structural steel needed by the automobile industry and the construction industry, etc. Among them, one of the main application fields of the hot-rolled coil is the oil and gas transmission pipeline. The hot-rolling coil can also be seen on the hull and deck of the huge and luxury cruise ships.

热轧卷板主要分为中厚宽宽钢带、热轧薄宽钢带和热轧薄板。其中中厚宽带钢的所占比例最大，约占热轧卷板总量的三分之二。

Hot rolled sheet is mainly divided into thick and wide steel strip, hot rolled wide steel strip and hot rolled sheet.Among them, medium and thick broadband steel accounts for the largest proportion, accounting for about two-thirds of the total hot-rolled coil plate.
