不锈钢板材经过处理后,表面光滑、光亮适度,呈现银灰色,具有金属色泽。为使不锈钢起到丰富装饰的作用,达到美观的效果,受到客户的欢迎,就必须对不锈钢进行表面加工,加工工艺可分为拉丝、镜面抛光、镀色等。
After treatment, the surface of stainless steel plate is smooth and moderately bright, showing silver gray and metallic color. In order to make stainless steel play the role of rich decoration, achieve the beautiful effect and be welcomed by customers, it is necessary to carry out surface processing on stainless steel. The processing process can be divided into wire drawing, mirror polishing, color plating, etc.
目前,这些工艺应用于电梯中厅门、吊顶、轿厢面板,起到丰富多样的装饰效果,给人们华丽的感觉。
At present, these processes are applied to the hall door, ceiling and car panel in the elevator, playing a rich and varied decorative effect, giving people a feeling of luxury and nobility.
本文将简述不锈钢拉丝、镜面、镀色等表面加工工艺,以及电梯不锈钢产品后期保养的方法,希望对从事电梯钣金生产的人员起到一定的借鉴作用。
This article will briefly describe the surface processing technology of stainless steel wire drawing, mirror surface, color plating, and the method of later maintenance of elevator stainless steel products, hoping to play a certain reference role for the personnel engaged in elevator sheet metal production.
电梯厅门、吊顶等不锈钢装饰件,采用表面处理好的板材加工成形,不锈钢卷板经整平、开料、表面处理、覆膜成板材,加工出来的装饰件,表面带有纹路,不需再进行表面加工。电梯现场安装完成后,撕掉保护膜就能起到相应拉丝、镜面等装饰效果。
The stainless steel decorative parts such as elevator hall door and ceiling are processed and formed with the surface treated plate. The stainless steel coil plate is leveled, cut, surface treated, and coated into a plate. The processed decorative parts have lines on the surface, and no surface processing is required. After the elevator is installed on site, the protective film can be torn off to achieve the corresponding decorative effects such as wire drawing and mirror surface.
拉丝工艺是不锈钢各类表面处理工艺当中较为常用的一种。板材拉丝是通过砂带研磨,砂带快速旋转,板材由输送带通过砂带,前面用磨料号数较大砂带(磨料号数越大,粒度越小,切削量越小,易于消除表面杂质),后面用号数小的砂带,对金属表面进行打磨,使表面得到一层粗细分布均匀的宏观纹路,也会在一定程度上减少不锈钢板的厚度(一般减少0.1 ~ 0.2mm)。电梯中不锈钢板材常用拉丝工艺效果一般为长纹、短纹(雪花砂)、乱纹等,具体工艺方法介绍如下:
Wire drawing process is one of the most commonly used surface treatment processes for stainless steel. The plate drawing is grinded by abrasive belt. The abrasive belt rotates rapidly. The plate passes through the abrasive belt by the conveyor belt. The front uses abrasive belt with larger abrasive number (the larger the abrasive number is, the smaller the particle size is, the smaller the cutting amount is, and it is easy to eliminate surface impurities). The back uses abrasive belt with smaller number to polish the metal surface, so that the surface can obtain a layer of macro-texture with uniform thickness distribution, The thickness of stainless steel plate will also be reduced to a certain extent (generally 0.1~0.2mm). The common drawing process effects of stainless steel plates in elevators are generally long lines, short lines (snowflakes), random lines, etc. The specific process methods are described as follows:
(1)长纹。通过在不锈钢表面用砂带机械来回打磨的方法加工处理后,得到表面状态为直线无断续的纹路,加工成电梯产品的装饰效果
(1) Long lines. After the stainless steel surface is processed by sanding back and forth, the surface state is straight without discontinuous lines. The decorative effect of processed elevator products is shown in Figure 2.

(2)短纹。砂带研磨与不锈钢表面纵向研磨时,砂带以一定的频率左右振动研磨,其加工表面呈断续状,同时呈现出一种类似雪花的晶粒效果,所以也称为雪花砂,加工成电梯产品装饰效果如图3 所示。
(2) Short veins. When abrasive belt grinding and longitudinal grinding of stainless steel surface, the abrasive belt vibrates and grinds at a certain frequency, and its processing surface is discontinuous, and presents a grain effect similar to snowflake, so it is also called snowflake sand. The decorative effect of elevator products processed is shown in Figure 3.

(3)乱纹。乱纹又叫和纹,是用砂带不规则地上下左右摆动研磨而形成的一种无规则、无明显纹路的拉丝纹,远观是一圈一圈的旋纹,近观是杂乱无章的乱纹,因纹路特殊,乱纹耐刻划性能、抗指纹性能更好,加工成电梯产品装饰效
(3) Scrub. The random pattern is also called "harmony pattern". It is a kind of irregular and non-obvious drawing pattern formed by grinding the abrasive belt irregularly up and down, left and right. From the far view, it is a circle of spiral pattern, while from the close view, it is a disordered random pattern. Because of the special pattern, the random pattern has better scratch resistance and fingerprint resistance, and is processed into elevator products with decorative effect
拉丝工艺加工纹路的粗细要深浅一致均匀,产品每一面的纹路根据设计和施工要求,达到自然美观的效果,产品的弯位允许有轻微的不影响外观的絮乱纹路,加工出来的不锈钢板拥有质感。
The thickness of the lines processed by the wire drawing process should be uniform. The lines on each side of the product should be natural and beautiful according to the design and construction requirements. The bending position of the product should allow slight flocculent lines that do not affect the appearance. The processed stainless steel plate has a texture.
我们看到的拉丝不锈钢能够清晰的显现每一根细微丝痕,使不锈钢哑光中泛出细密的发丝光泽,这么特别的丝状纹路看得见摸不着(因为丝纹比较精细,即使摸上去也不会有任何感觉)。
The brushed stainless steel we see can clearly show every tiny trace, making the stainless steel matt shine with fine hair luster. Such special filiform lines can be seen and touched (because the filiform lines are relatively fine, even if you touch it, you will not have any feeling).
镜面在不锈钢中装饰档次较高,加工工艺比拉丝要复杂,是在原板表面采用机械式抛光,使表面平坦,光度与镜面相同,可以分为打磨和出光两部分。打磨又分粗磨、半精磨、精磨三个工序,出光分为打蜡、光亮两个工序,整个工序可以总结为粗磨→半精磨→精磨→打蜡→光亮,操作步骤如下:
The mirror surface is of high decoration grade in stainless steel, and the processing process is more complex than wire drawing. It is mechanical polishing on the surface of the original plate to make the surface flat, with the same brightness as the mirror surface, which can be divided into two parts: polishing and polishing. Grinding can be divided into three processes: rough grinding, semi-fine grinding and fine grinding. The polishing can be divided into two processes: waxing and polishing. The whole process can be summarized as rough grinding → semi-fine grinding → fine grinding → waxing → polishing. The operation steps are as follows:
(1)粗磨。选用料号较小的磨料,一般选用600# 砂带,往返成直线对板材表面进行打磨,去除板材表面杂质和粗糙的地方。
(1) Rough grinding. The abrasive with smaller material number is selected. Generally, 600 # abrasive belt is used to grind the plate surface in a straight line to remove impurities and rough places on the plate surface.
(2)半精磨。用800# 砂带按照步方法打磨表面,主要是对粗磨后产生的印痕进一步的细磨,达到表面无印痕,基本变亮。
(2) Semi-finish grinding. Grind the surface with 800 # abrasive belt according to the first step method, mainly to further grind the marks produced after rough grinding, so as to achieve no marks on the surface and basically brighten.
(3)精磨。用1000# 砂带继续打磨,主要是对板材表面的细小纹线修正磨削,板材表面进一步变亮,基本接近镜面效果。
(3) Fine grinding. Continue grinding with 1000 # abrasive belt, mainly to correct and grind the fine lines on the surface of the plate, and the surface of the plate will be further brightened, basically close to the mirror effect.
(4)打蜡。选用羊毛轮和青蜡,在羊毛轮上粘满青蜡,用上述抛光方法对板材表面进行镜面磨光,本工序主要目的是完成板材镜面磨光,而不是进一步磨削。
(4) Waxing. Select wool wheel and green wax, stick green wax on the wool wheel, and use the above polishing method to polish the plate surface. The main purpose of this process is to finish the plate mirror polishing, not further grinding.
(5)光亮。本工序是一道工序,用干净的棉布轮对经过镜面后的板材进行表面摩擦,目的是将板材表面擦干净、擦亮。
(5) Bright. This process is the last one. Use clean cotton cloth wheel to rub the surface of the plate after the mirror surface to clean and polish the plate surface.
