在鋼材進(jìn)入涂裝之前，表面附著的氧化皮、銹層和焊渣是影響涂層附著力和防腐壽命的頭號(hào)敵人。自動(dòng)式（通過(guò)式）拋丸機(jī)的登場(chǎng)，以高達(dá)Sa2.5-Sa3級(jí)的清理等級(jí)和連續(xù)不間斷的流水作業(yè)，為鋼板、型鋼、鋼結(jié)構(gòu)件提供了一場(chǎng)高效徹底的“表面洗禮”。它不僅除銹，更是一臺(tái)兼具強(qiáng)化與預(yù)處理功能的關(guān)鍵設(shè)備。

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、使用范圍：面向大批量連續(xù)作業(yè)場(chǎng)景

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

通過(guò)式拋丸機(jī)特別適用于大批量、連續(xù)化的表面處理需求。在工程機(jī)械行業(yè)（挖掘機(jī)、裝載機(jī)結(jié)構(gòu)件）、汽車制造（車架、車橋、底盤）、鋼結(jié)構(gòu)（H型鋼、橋梁構(gòu)件）、船舶制造及軌道交通等行業(yè)均承擔(dān)著核心預(yù)處理任務(wù)。

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.

其輥道式機(jī)型專為板材、型材設(shè)計(jì)，輸送速度可調(diào)，能處理長(zhǎng)達(dá)12米、重超5噸的大型工件，并能靈活與鋸切、鉆銑、噴漆烘干等后續(xù)工序集成，形成完整預(yù)處理生產(chǎn)線。

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、核心優(yōu)勢(shì)：高效自動(dòng)化與極致環(huán)保

2、 Core advantages: Efficient automation and ultimate environmental protection

自動(dòng)式拋丸機(jī)通過(guò)高速拋射彈丸沖擊工件表面，瞬間剝離氧化皮和銹蝕。核心部件拋丸器采用高鉻耐磨材料，單臺(tái)拋丸量可達(dá)220-360kg/min，配合PLC與觸摸屏智能控制系統(tǒng)，實(shí)現(xiàn)上料、拋丸、卸料全流程自動(dòng)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.

全機(jī)配備丸料循環(huán)回收裝置，分離效率高達(dá)99%，極大降低了耗材成本。除了清理效果，拋丸過(guò)程還能消除工件焊接內(nèi)應(yīng)力，在表面形成均勻的粗糙度（錨紋），從而提高漆膜附著力與工件抗疲勞強(qiáng)度，永久性延長(zhǎng)結(jié)構(gòu)使用壽命。

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.

在環(huán)保指標(biāo)上，現(xiàn)代拋丸機(jī)搭載高效除塵系統(tǒng)，粉塵排放濃度可控制在15mg/m?以下，噪聲值控制在85分貝以內(nèi)，遠(yuǎn)優(yōu)于國(guó)家排放標(biāo)準(zhǔn)。從開(kāi)關(guān)量操控到數(shù)字功率控制的四代技術(shù)演進(jìn)，使其在能效與可靠性上持續(xù)迭代，成為金屬預(yù)處理環(huán)節(jié)不可或缺的“剛需裝備”。

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.
