Steps and inspection methods for installing cast iron platforms

Adjust the cast iron platform to a certain level,with the load evenly distributed on each support point.The ambient temperature is(20±5)℃.Vibration should be prevented during use.The advantages of using a pad iron device on the cast iron platform are that the device is easy to move

Cast iron platform installation method:

1.Shim iron device:adjust the cast iron platform to the appropriate level and evenly distribute the load on each support point.The ambient temperature is(20±5)℃.Vibration should be prevented during use.The advantages of using a pad iron device on a cast iron platform are that the device is easy to move.

2.Support device:Gently place the cast iron platform onto the support and adjust the fine adjustment bolts on the support to the level of the cast iron platform.The bracket can reduce the labor intensity of inspectors.The height of the bracket is usually around 500-600mm.

3.Anchor device:The cast iron platform can design anchor devices.Firstly,the user prepares the foundation and embedded holes according to the drawings of the cast iron platform.Then,the anchor device is placed in the reserved holes set in advance,and the degree of adjustment of the cast iron platform is adjusted,

4.Anchor bolt device:The cast iron platform designs the device according to the user's request,and the anchor bolt device.

Cast iron platforms are tools for industrial consumption,and the correct use and maintenance of cast iron plates are important conditions for adhering to the accuracy of cast iron plates and extending their service life.They are also an indispensable part of the worker's job obligation system.By correctly using cast iron flat plates,users of cast iron square boxes can fully utilize the existing cast iron flat plates,expand their application range,reduce measurement errors,improve measurement accuracy,and successfully complete detection tasks.

Why do we always emphasize the importance of maintaining and nurturing cast iron inspection platforms and flat plates?If they are only used without maintenance,no matter what,they will soon lose their accuracy and become waste.On the contrary,if cast iron platform manufacturers spare no effort in using and maintaining cast iron flat plates in their daily work,they can still maintain good accuracy despite years of use and wear.

The quality of cast iron and the quality of heat treatment have a significant impact on the performance of cast iron flat plates.Cast iron flat plates are of high quality,and the series of cast iron flat plates consumed by our factory are all made of HT200-300 grade cast iron,using the disappearing mold casting process.After drawing design,model consumption,pouring,sand cleaning,annealing,rough processing,secondary tempering treatment,CNC precision machining by the inspection platform manufacturer,scraping,and factory inspection,more than 10 processes have been completed,The hardness reaches HB170-240,the load-bearing capacity can reach hundreds of tons,the accuracy is stable,and the performance is good.

The cast iron flat plate with sand inclusion has a layer of metal nodules or flakes on the surface of the casting,and the inspection platform has a layer of molding sand sandwiched between the metal nodules and the casting.Pores are lubrication holes of varying sizes located inside,on,or near the surface of cast iron flat castings,with shapes ranging from round,long,and irregular,individual,and exfoliating.The marking platform should appropriately reduce the pouring temperature of the metal.Hot cracking has penetrating or non penetrating cracks on cast iron flat castings(note if they are curved),and the metal skin at the cracking point of the shock absorber pad iron oxidizes.Improve the slag blocking ability of the pouring system.On the surface of cast iron flat castings,sticky sand is completely or partially covered with a layer of metal(or metal oxide)mixed with sand(or coating)or a layer of burnt sand structure.Customized cast iron parts result in rough and rough surface of the castings.

Strictly control the function and appearance of the molding sand,and pay attention to cleaning the mold cavity before molding.Prevent sudden changes in wall thickness.Improve the refractory cast iron platform for molding sand and core sand.

The cast iron flat workface adopts scraping and grinding technology,and can process V-shaped,inspection platform T-shaped,U-shaped grooves,dovetail grooves,round holes,long holes,etc.on the workface.The wall thickness of cast iron flat castings should be as uniform as possible,reducing the viscosity of slag,increasing the temperature of molten iron,and reducing the amount of metal suction during melting.

Cast iron square box cold cracking has penetrating or non penetrating cracks(mainly straight)on cast iron flat castings,and the metal skin at the crack site oxidizes.Castings cannot be quenched.Do not open the mold too early.
