Storage

I.Steel plate cutting
The H section  steel plate should be checked again by the factory and shall be applied under the condition of up to design and specified requirements after checking. Steel plate cutting should be aimed at quality guarantee and material saving. For each process like plate cutting,H type assembly, components assembly and pre-assembly should be carried out by profession setting-out worker precisely on processing surface and assembly sample plates.To guarantee the accuracy of the components'geometrical dimension,tolerance of form and position, angle and contact surface,inspection is necessary by inspector after setting out.In order to ensure the cutting quality,the surface of the ultra-thick plate is subjected to the surface carburizing hardness test before cutting.The CNC cutting equipment is preferred for cutting.The high purity 98.0% acrylic gas and 99.99% liquid oxygen gas are used to guarantee the smoothness and flatness of the cutting surface without notches and slags.The groove is cut by a special imported cutting machine.

II.H section steel assembly
The assembly process is set up on the imported H section production line.4 hydraulic positioning system press firmly against between the upper/lower flange and web plates in position. The adjust the parallelism of the flange plates and perpendicularity between flange and web plates and get them fixed after. The fixing welding should adopt C02 gas shielded welding.

V.Simulated assembly of component
1.Get familiar with component shop drawing and technical requirements.
2.The model components need to re-check by related department after making and finalizing of the model components and then to assemble.
3.Accurate mark-up
4.Inspect the component after first assembly.For multi-group components, pre-assembly for the first group and then batch assembly after qualified test.

VI.Manual welding

VIII.Painting
The surface of the members should be in even,flat, glossy and full painting without manifest of cracking, peeling and pin holing.The color and coating thickness should also meet design requirements.If there is no certain requirements,the following standards should be followed:thickness is 150μm indoor while 125μm outdoor.The allowable deviation is -25μm.The allowable deviation of dry paint film thickness for each-time painting
Two coats of primer:thickness being40±5μm; Two coats of finish paint:thickness being 60±5μm.
