1.开卷焊接

1. Unwinding welding

开卷:对钢卷停止开卷,提供连续运转所需钢带,普通采用两个开卷机。

大富彩票平台Uncoiling: Stop uncoiling the coil and provide the strip needed for continuous operation。 Two uncoilers are usually used。

焊接:对前行带钢的带尾与后行带钢的带头停止焊接,确保机组的连续消费。

Welding: Stop welding the tail of the front strip and the head of the back strip to ensure the continuous consumption of the unit.

2.脱脂清洗

2. Degreasing and cleaning

清洗段是对带钢外表停止清洗,除去轧制油和铁粉,以取得良好的镀层附着性和外表质量,普通包括喷淋、刷洗、电解清洗、刷洗、喷淋、挤干和热风烘干等设备,清洗段对热镀锌是比拟重要的,是取得好的带钢外表质量的重要步骤。

Cleaning section is to stop cleaning the appearance of strip steel, remove rolling oil and iron powder, in order to obtain good coating adhesion and appearance quality. Generally, cleaning section includes spraying, brushing, electrolytic cleaning, brushing, spraying, extrusion drying and hot air drying equipment. Cleaning section is comparatively important for hot galvanizing and is an important step to achieve good surface quality of strip steel.

3。退 火

3. annealing

对轧硬态的带钢停止再结晶退火,以取得良好的产品机械性能,经过控制炉内氛围,以取得良好的带钢镀层性能,退火炉普通由预热、加热、均热、冷却等几个段组成。

The annealing furnace is usually composed of preheating, heating, soaking and cooling sections.

4.镀(铝)锌

4. Zinc plating (aluminium)

镀锌:对带钢停止浸入式镀锌或其它金属锌层。可依据产种类类设置一个或多个锌锅。

Galvanizing: stop immersion galvanizing or other metallic zinc coating on strip steel。 One or more zinc pots can be set up according to the type of production。

气刀锌层控制:经过气刀向出锌锅后的带钢外表喷吹气体,普通是空气或纯氮气,来控制带钢外表的镀层厚度。

Air Knife Zinc Layer Control: Air is injected into the strip surface after the air knife comes out of the zinc pot, usually air or pure nitrogen, to control the thickness of the coating on the strip surface.

5。冷 却

5. cooling

合金化处置:对镀锌后的带钢停止加热,取得新铁合金锌层的工艺,普通包括加热、保温和冷却工艺。

Alloying disposal: The process of obtaining new ferroalloy zinc layer by stopping heating the galvanized strip, usually including heating, heat preservation and cooling.

镀后空气冷:采用空气喷吹,对镀完锌的带钢停止冷却,确保进入頂辊时镀层得到冷却。

Air cooling after plating: Air injection is used to stop cooling the galvanized strip to ensure that the coating is cooled when entering the top roll.

水淬冷却:对镀后带钢进一步冷却,确保带钢在进入平整前的温度契合工艺请求。

Water quenching cooling: further cooling of the strip after plating to ensure that the temperature of the strip before leveling meets the process requirements。

6.平整拉矫

6. Flat stretching and straightening

平整:对带钢停止小轧制力的轧制,消弭低碳钢的屈从平台、改善带钢性能,取得希冀的带钢外表粗糙度,改善带钢板形、取得良好的平直度等。

大富彩票平台Flatness: Stop rolling of small rolling force on strip, eliminate the yield platform of low carbon steel, improve the performance of strip, achieve the desired surface roughness of strip, improve the shape of strip, achieve good flatness, etc.

拉矫:带钢停止拉伸矫直,进一步改善板型。

Straightening: Strip steel stop stretching and straightening, and further improve the shape of the plate.

7.后处置

大富彩票平台7。 post disposal

对带钢停止钝化或其它化学外表处置,以取得希望的耐腐蚀、光滑或其它请求,普通采用喷淋挤干或辊涂烘干方式。

To stop passivation or other chemical surface treatment of strip steel in order to obtain desired corrosion resistance, smoothness or other requirements, spray extrusion drying or roll coating drying is generally used。

8.检 查

8. check

依据需求对带钢停止切边,以取得适宜的宽度精度。

大富彩票平台According to the requirement, the strip is stopped trimming in order to obtain the appropriate width accuracy.

9.涂 油

9. oiling

对带钢停止涂油,取得一定的防锈和光滑性能。

The strip steel is stopped oiling to obtain certain anti-rust and smooth properties.

10。卷 取

10。 coiling

将带钢卷绕成盘材或板卷。

The strip is coiled into a coil or sheet。
