Description

一种多道喷砂除磷工艺  Multi-channel sand blasting and phosphorus removal process
技术领域Technical field
本发明属于钢带除磷技术领域,具体涉及一种多道喷砂除磷工艺。The invention belongs to the technical field of steel strip dephosphorization, and particularly relates to a multi-channel blasting and phosphorus removal process.
背景技术Background technique
众所周知,不锈钢带由于具有精美的外表和优良的抗腐蚀性能,已逐渐广泛应用于电子、装饰、五金和厨房设备等行业。传统的不锈钢带都是光滑面,虽然这种光滑面不锈刚带具有上述优点,但易被划伤。As we all know, stainless steel belts have been widely used in electronics, decoration, hardware and kitchen equipment due to their exquisite appearance and excellent corrosion resistance. The conventional stainless steel belts are smooth surfaces, and although the smooth surface stainless steel belt has the above advantages, it is easily scratched.
钢带外表面会产生氧化皮,在进行加工前,必须将钢带表面的氧化皮清理干净。目前,国内企业普遍采用化学酸洗方式(如:盐酸、硫酸、硝酸、氢氟酸)清除钢带外表面氧化皮,环境污染严重;抛丸法除鳞能够部分去除钢带外表面的氧化皮,但粉尘污染严重,一般配除尘设备,且难以满足工艺要求,容易使钢带表面产生凹坑,表面硬化;喷砂法是将低压的压缩空气与砂混合清理金属表面,粉尘污染很大,除尘设备处理效果不理想。The outer surface of the steel strip will produce scale, and the scale on the surface of the strip must be cleaned before processing. At present, domestic enterprises generally use chemical pickling methods (such as hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid) to remove oxide scale on the outer surface of steel strips, and the environmental pollution is serious; shot blasting descaling can partially remove the scale on the outer surface of the steel strip. However, dust pollution is serious, generally equipped with dust removal equipment, and it is difficult to meet the process requirements, it is easy to cause pits on the surface of the steel strip, and the surface is hardened; the sandblasting method is to mix the low-pressure compressed air with the sand to clean the metal surface, and the dust pollution is very large. Dust removal equipment is not ideal.
近年来出现了在不锈钢板(带)表面进行喷砂来生产喷砂面不锈钢板(带)的报道。但由于喷砂工艺是通过往复移动的喷嘴将砂粒喷打在不锈钢板(带)上,喷嘴喷出的砂粒束中心要比砂粒束边沿的能量要强得多,使得不锈钢板(带)上各点的砂粒分布不均,因此,用这种方法生产的喷砂面不锈钢带,质量不高。又由于喷砂工艺是通过往复移动的喷嘴将砂粒喷打在不锈钢板(带)上,喷嘴喷出的砂粒束较小,只能一片一片的对裁剪好的不锈钢板(带)进行喷砂,无法实现大面积喷砂处理,生产效率较低。In recent years, reports have been made on the surface of stainless steel sheets (belts) to produce sandblasted stainless steel sheets (belts). However, since the sand blasting process sprays the sand on the stainless steel plate (belt) through the reciprocating nozzle, the center of the sand beam emitted from the nozzle is much stronger than the energy of the edge of the sand beam, so that the points on the stainless steel plate (belt) The sand grains are unevenly distributed, so the blasted surface stainless steel belt produced by this method is not high in quality. Moreover, since the sand blasting process sprays the sand on the stainless steel plate (belt) through the reciprocating nozzle, the sand beam emitted from the nozzle is small, and only the one piece of the cut stainless steel plate (belt) can be sandblasted. Large-area blasting is not possible and production efficiency is low.
现有公开的一种一种钢带除鳞的方法包括:将钢带通过拉料辊送入破鳞装置,破碎钢带表面的鳞皮;将经过破鳞处理后的钢带送入喷砂装置,向钢带表面喷钢砂、高压水和高压气,对钢带表面的鳞皮进行进一步的破碎和冲刷;将经过喷砂处理后的钢带送入刷辊装置,对钢带表面进行抛刷,进一步去除残留的鳞皮并使钢带表面平滑;将经过抛刷处理后的钢带送入带刷装置,刷除钢带上表面经抛刷后留下的粉屑和遗留的鳞皮;将经过刷除处理后的钢带送入清洗装置,用清水冲洗钢带表面;清洗后的钢带通过拉料辊进行收卷。该除磷方法存在喷嘴将砂粒喷打在不锈钢板(带)上,由于喷嘴喷出的砂粒束中心要比砂粒束边沿的能量要强得多,使得不锈钢板(带)上各点的砂粒分布不均,容易使钢带表面产生凹坑,表面硬化,导致喷砂面不锈钢带质量不高。A method for descaling a steel strip disclosed in the prior art comprises: feeding a steel strip through a pulling roller into a scale breaking device, crushing the scale skin on the surface of the steel strip; and feeding the steel strip after the scale breaking treatment into the sandblasting The device sprays steel grit, high-pressure water and high-pressure gas onto the surface of the steel strip to further crush and wash the scale skin on the surface of the steel strip; the steel strip after the sandblasting is sent to the brush roller device to carry out the surface of the steel strip Brushing, further removing residual scales and smoothing the surface of the steel strip; feeding the brushed steel strip into the brushing device to remove the dust and leftover scale left after the upper surface of the steel strip is brushed off The steel strip after being brushed is sent to a cleaning device, and the surface of the steel strip is washed with water; the cleaned steel strip is wound by a pulling roller. In the phosphorus removal method, the nozzle sprays the sand on the stainless steel plate (belt), because the center of the sand beam emitted from the nozzle is much stronger than the energy of the edge of the sand beam, so that the sand particles at various points on the stainless steel plate (belt) are not distributed. Both of them are easy to cause pits on the surface of the steel strip and the surface is hardened, resulting in a low quality of the stainless steel strip on the sandblasted surface.
