Cast iron floor rail

The ground rail is usually called cast iron ground rail,T-groove ground rail,ground trough iron,foundation iron,ground beam,cast iron ground beam,strip flat plate,strip platform.

The cast iron ground rail adopts gray cast iron HT200-250,with a working surface hardness of HB170-240.The casting undergoes two rounds of artificial annealing at 600℃-700℃or natural aging for 2-3 years to remove internal stress,with stable accuracy and good performance.

The main purpose of the ground rail is to design and assemble it into a cast beam platform based on the fixed points of the equipment.It does not need to be made into a large platform,which saves material costs and can occupy a small space.It has a high cost performance ratio and is mainly used for the assembly,testing,welding,and inspection of large equipment.We can produce and process specific specifications of ground rails based on the drawings of the demand side or through mutual agreement.

The material of cast iron ground rail:cast iron HT200-300,with a working surface hardness of HB170-240.After manual tempering treatment,the accuracy of the product is stable and can be improved.

Advantages of ground rails:The use of ground rails can be spliced into large cast iron flat plates,saving material costs and occupying very little space.

The specifications of the ground rail can be made according to the drawings according to user needs,or customized through negotiation between both parties.

Technical requirements for laying cast iron ground rails:

1.The fixing method for cast iron ground rails is to fix them firmly with M8 iron expansion nails or shooting nails at the required spacing(about 500-700mm)on both sides of the inner side of the track.The bottom surface of the track should be tightly adhered to the ground,without any virtual span gap,to prevent bending deformation of the ground rail under load.

2.Installation of the ground track:using a strip bridge slab and an imaging level.First level one ground rail,then use it as a benchmark and proceed with the initial adjustment downwards in sequence.Then cement grouting is carried out,and after the cement slurry solidifies,precision adjustment inspection is carried out.

3.The burial of cast iron ground rails should be level with the ground decorative layer or slightly higher than 3-5 mm

4.After the installation of the ground track,the horizontal deviation should not exceed 1mm within any 1m length,and the total length should not exceed 2mm.The horizontal deviation between the corresponding points of the tracks should not exceed 1mm,and the parallelism deviation between every two tracks should be less than 2mm.
