鋼板下料采用CNC數控火焰切割機,數控系統為國外專業(yè)技術;零散小料采用剪板機和半自動切割機;切割前將鋼板切割區(qū)域表面的鐵銹、污物等清理干凈;切割后清除溶渣和飛濺物:建筑結構用鋼材主要為Q235B(美國A36,日本SS41,日本SM41,德國St37)、Q345B(美國A441,日本SM50,德國St52)。
Main steel plate cutting uses the advanced CNC flame cutting machine: Scattered plate cutting use plate shears and semi-automatic cutter machine; Clean rust and dirtiness out of cutting area of the steel plate before cutting,and Durge the plate of dross and splash after cutting. The steel material of building structure is maily GB-Q235B( ASTM-A 3 6, JIS-S S41, JIS-SM41, DIN-St37), GB-Q345B(ASTM-A441, JIS-SS50, DIN-St52 ).
對采用的鋼材、焊接材料、焊接方法、焊后熱處理等進行焊接工藝評定并根據評定報告確定焊接工藝;焊接工藝評定符合《建筑鋼結構焊接規(guī)程》GBJ81-91;焊工全部經過考試并取得合格證,焊絲在使用前清除油污、鐵銹;焊條、焊絲使用前按說明書規(guī)定的烘焙時間和溫度進行烘焙:焊縫外形尺寸符合現行國家標準《鋼結構焊縫外形尺寸》GBI 0854-89;探傷焊縫條例國家標準《鋼焊縫手工超聲波探傷方法和探傷結果分級》Gb11345-89的規(guī)定。
All the steel material, welding material, weldine method and hot treatment after weldine have evaluation report, and we dctcrmine the wclding proccdure accordingly. the xvclding proccdure confirm to national stzindard GBJ81-91 89 , GB11345-89;The wcldcr all passed the examInatIon and successed to get certification.
H型鋼組裝采用中間焊點、自動對中組立機;組裝前,零件、部件全部檢查合格;連接接觸面和焊縫邊緣30-50mm范圍內的鐵銹、毛刺、污垢、冰雪等清理干凈。組裝精度滿足國家標準《鋼結構工程施工及驗收標準-GB50205-2001規(guī)定。
Asscmblling of H shape stccl with the middle joint and auto alignment machine. Checking all components and ensuring they are qualif-ied before assemblling. Cleaning the rust, burrs, diriy, ice or snow on the contact surface and the surface within 30-50mm of the weld edges. Assembling precision fully meets the national standard of GB5025-2001:Code for acceptance of construction quality of steel structurcs.
碳素結構鋼在環(huán)境溫度低于-16℃時,低合金結構鋼在環(huán)境溫度低于-12℃不得進行冷矯正和冷彎曲;碳素結構鋼和低合金結構鋼在加熱矯正時,加熱溫度不得超過900℃;矯正后的鋼材表面無明顯的凹痕或損傷,劃痕深度小于0.5mm;鋼結構矯正后的偏差符合現行國家標準《鋼結構工程施工及驗收規(guī)范》GB50205-2001。
Carbon structure steel and -12℃ for low-alloy structure steel. The temperature of heated correction couldn't higher than 900℃ for both steels. There will not be obvious dents and damage and the scratches deeper than 0.5mm on the corrected surface. The deviation after corrected is according to the national standard GB50205-2001 .
鋼構件在涂層之前應進行除銹處理,銹除得干凈則可提高底漆的附著力,直接關系到涂層質量的好壞。本公司采用大型拋丸清理機滿足這一涂裝工藝的要求,使構件達到Sa3除銹等級。該機設有多個拋丸器大型清理室,可滿足各種鋼構件及H型鋼的表面清理要求。
Before coating, rust treatment should be done, for steel components rust primer in addition to clean and can improve the adhesion of the coating is directly related to the quality of the good or bad. The company uses a large
abrator coating process to meet this requirement, so that components reach Sa3 rust grade. The machine has a number of large-scale clean-up shot blasting rooms, which can meet various requirements of steel components and surface
cleaning H-beam.
