在钢材进入涂装之前，表面附着的氧化皮、锈层和焊渣是影响涂层附着力和防腐寿命的头号敌人。自动式（通过式）抛丸机的登场，以高达Sa2.5-Sa3级的清理等级和连续不间断的流水作业，为钢板、型钢、钢结构件提供了一场出色有效的“表面洗礼”。它不仅除锈，更是一台兼具强化与预处理功能的关键设备。

Before the steel enters the coating process, the oxide scale, rust layer, and welding slag attached to the surface are the number one enemies that affect the adhesion and anti-corrosion life of the coating. The introduction of automatic (through type) shot blasting machines provides an efficient and thorough "surface baptism" for steel plates, steel sections, and steel structural components with a cleaning level of up to Sa2.5-Sa3 and continuous and uninterrupted flow operations. It is not only rust removal, but also a key equipment with both strengthening and pre-treatment functions.

一、使用范围：面向大批量连续作业场景

1、 Scope of use: Targeting large-scale continuous work scenarios

通过式抛丸机非常适用于大批量、连续化的表面处理需求。在工程机械行业（挖掘机、装载机结构件）、汽车制造（车架、车桥、底盘）、钢结构（H型钢、桥梁构件）、船舶制造及轨道交通等行业均承担着核心预处理任务。

The through type shot blasting machine is particularly suitable for large-scale, continuous surface treatment needs. Core pre-processing tasks are undertaken in industries such as construction machinery (excavators, loader structural components), automobile manufacturing (frames, axles, chassis), steel structures (H-beams, bridge components), shipbuilding, and rail transit.

其辊道式机型专为板材、型材设计，输送速度可调，能处理长达12米、重超5吨的大型工件，并能灵活与锯切、钻铣、喷漆烘干等后续工序集成，形成完整预处理生产线。

The roller conveyor model is designed specifically for sheet metal and profiles, with adjustable conveying speed. It can handle large workpieces up to 12 meters long and weighing over 5 tons, and can be flexibly integrated with subsequent processes such as sawing, drilling, milling, painting, and drying to form a complete pre-processing production line.

二、核心优势：出色自动化与出色环保

2、 Core advantages: Efficient automation and ultimate environmental protection

自动式抛丸机通过高速抛射弹丸冲击工件表面，瞬间剥离氧化皮和锈蚀。核心部件抛丸器采用高铬耐磨材料，单台抛丸量可达220-360kg/min，配合PLC与触摸屏智能控制系统，实现上料、抛丸、卸料全流程自动化操作。

The automatic shot blasting machine uses high-speed projectile to impact the surface of the workpiece, instantly peeling off the oxide skin and rust. The core component of the shot blasting machine is made of high chromium wear-resistant material, with a single shot blasting capacity of 220-360kg/min. Combined with PLC and touch screen intelligent control system, it realizes the full process automation operation of loading, shot blasting, and unloading.

全机配备丸料循环回收装置，分离效率高达99%，出色大降低了耗材成本。除了清理效果，抛丸过程还能消除工件焊接内应力，在表面形成均匀的粗糙度（锚纹），从而提高漆膜附着力与工件抗疲劳强度，永久性延长结构使用寿命。

The whole machine is equipped with a pellet recycling device, with a separation efficiency of up to 99%, greatly reducing the cost of consumables. In addition to the cleaning effect, the shot blasting process can also eliminate the welding internal stress of the workpiece, forming a uniform roughness (anchor pattern) on the surface, thereby improving the adhesion of the paint film and the fatigue strength of the workpiece, and permanently extending the service life of the structure.

在环保指标上，现代抛丸机搭载出色除尘系统，粉尘排放浓度可控制在15mg/m?以下，噪声值控制在85分贝以内，远优于国家排放标准。从开关量操控到数字功率控制的四代技术演进，使其在能效与可靠性上持续迭代，成为金属预处理环节不可或缺的“刚需装备”。

In terms of environmental indicators, modern shot blasting machines are equipped with efficient dust removal systems, and the dust emission concentration can be controlled at 15mg/m? Below, the noise level is controlled within 85 decibels, far exceeding the national emission standards. The evolution of four generations of technology from switch control to digital power control has continuously iterated on energy efficiency and reliability, making it an indispensable "essential equipment" in the metal pretreatment process.
