A3冷轧板是什么材料啊

冷轧板卷是以热轧钢卷为原料，在低于加工硬化温度的室内温度下冷轧而成，包括板卷在内，国内许多钢厂都能生产，如鞍钢、武钢、鞍钢等，其中板材供应称为厚钢板，又称盒式平板电脑或平板电脑；长短不一，供应成板的叫钢链，也叫不锈钢板。
冷轧的定义；

冷轧板卷是在加工硬化条件下的冷轧，但通常理解为在常温下对原材料进行冷轧。铝冷轧分为中厚板轧制和铝箔轧制。厚度约为的称为板，厚度小于等于的称为箔
生产工艺： 冷轧板卷由于在加工过程中没有进行加热，无法发现热冲压中经常出现的黑点、氧化皮等缺陷，工艺性能好，平整度高。此外，冷轧产品的规格精度高，产品的特点和机理可以考虑一些独特的应用规则，如电磁感应特性、低合金板材特性等。
规格型号：厚度0.3-4mm，总宽700-2050mm，厚钢板长度1150-6505mm。
特点：选用高碳钢牌号为关键，要求具有优良的冷拔和电焊特性，以及必要的冲压模具特性。
主要用途： 冷轧板卷应用广泛，如汽车工业、电器产品、机车、航空、五金机械仪表板、罐头食品和水果等。
冷轧钢板是冷轧碳素钢板的总称，又称冷轧钢板，又称冷轧钢板。冷轧钢板采用普通碳素钢热轧带钢，经深冷轧制后制成厚度小于4mm的厚钢板。由于冷轧在室温下不产生氧化皮，冷轧钢板具有良好的工艺性能、高精度规格和淬火液，其物理性能和使用性能均优于热轧钢板。在许多行业，尤其是家电制造业，它已逐渐取代热轧钢板。

Cold rolled sheet and coil are made of hot rolled coil as raw material, cold rolled at indoor temperature below work hardening temperature, including sheet and coil, which can be produced by many steel mills in China, such as Angang, WISCO, Angang, etc. In which the sheet supply is called thick steel plate, also known as box plate or tablet computer; Long and short, supply into a plate called steel chain, also known as stainless steel sheet.

The definition of cold binding;
It is cold rolling under work hardening, but it is usually understood that it is cold rolling of raw materials under normal temperature. Aluminum cold rolling is divided into plate rolling and foil rolling. The thickness of --- ~ or so is called plate, and the thickness of --- ~ or below is called foil
Production process: because heating is not carried out in the processing process, the defects such as black spots and scale often appeared in hot stamping can not be found, and the process performance is good and the smoothness is high. In addition, the specification of cold rolled products is high precision, and the characteristics and mechanism of products can consider some unique application regulations, such as electromagnetic induction characteristics, low alloy plate characteristics, etc.
Specification and model: the thickness is 0.3-4mm, the total width is 700-2050mm, and the length of thick steel plate is 1150-65050mm.
Characteristics: high carbon steel grade is selected as the key, and it is required to have excellent cold drawing and electric welding characteristics, as well as necessary stamping die characteristics.
Main application: cold rolled steel strip has a wide range of applications, such as automobile industry, electrical products, locomotives, airlines, hardware and mechanical instrument panel, canned food and fruit, etc.
Cold rolled steel plate is the general name of cold rolled carbon steel plate, also known as cold rolled steel plate, also known as cold rolled steel plate. Cold rolled steel plate is made of common carbon steel hot rolled strip, which is made into thick steel plate with thickness less than 4mm after deep cold rolling. Because cold rolling at room temperature does not cause scale, cold rolled steel sheet has good process performance, high precision specifications, and quenching solution, its physical properties and service performance are better than hot rolled steel sheet. In many industries, especially the household electrical appliances manufacturing industry, it has gradually replaced hot rolled steel sheet.
