Ordinary ground rail

Ordinary ground rails can be commonly referred to as T-shaped groove ground rails,ground beams,ground channel iron,and foundation channel iron.They are mainly designed and spliced into a cast beam platform based on the fixed points of equipment,and are used for the assembly,experimentation,welding,and inspection of large equipment.This way,there is no need to make it into a large platform,which saves material costs and takes up very little space,making it highly cost-effective.

The material of ordinary ground rails

Cast iron HT200-300,task surface hardness HB170-240,after two manual treatments(artificial annealing at 600-700 degrees and aging for 2-3 years),the accuracy of the ground rail remains unchanged and can be improved.

Main uses of ordinary ground rails

Design and assemble a cast beam platform based on the fixed points of the equipment,mainly used for the assembly,testing,welding,and inspection of large equipment.The advantage of using ordinary ground rails is that it does not need to be made into a large platform,which saves material costs and can take up very little space!It can be said that it is a high cost-effective rail application:designed and assembled into a cast beam platform based on the fixed points of the equipment,mainly used for the assembly,testing,welding,and inspection of large equipment.

The advantages of ordinary ground rails

This way,there is no need to make it into a large platform,which saves material costs and takes up very little space,making it highly cost-effective.

Specifications of ordinary ground rails

The specific specifications can be made according to the buyer's drawings or agreed upon by both parties for production and processing.

What is the difference between self heating aging and thermal aging of ordinary ground rails?

1.The natural time efficiency of ordinary ground rails is an ancient method of time efficiency.It places the components outdoors,and after several months to several years of wind,sun,rain,and seasonal temperature changes,it promotes the relaxation of residual stress and stabilizes the dimensional accuracy.The advantages of natural aging are:good dimensional stability of components,simple and feasible methods,.The disadvantage is that the production cycle is long,occupies a large space,is difficult to manage,and cannot detect defects in the components in a timely manner,which has gradually been eliminated.

2.Heat aging:Slowly and uniformly heat ordinary ground rail castings from room temperature to around 550℃,keep them warm for 4-8 hours,and then strictly control the cooling rate to below 150℃before being taken out of the furnace.The requirements for thermal aging process are strict,such as requiring the temperature difference inside the furnace not to exceed±25℃,the heating rate not to exceed 50℃/hour,and the cooling rate not to exceed 20℃/hour.The high temperature inside the furnace should not exceed 570℃,and the insulation time should not be too long.If the temperature exceeds 570℃and the insulation time is too long,it will cause a decrease in the strength of the components.If the heating rate is too fast,the heating rate at the thin-walled part of the component is much faster than that at the thick wall,and the temperature difference between different parts of the component increases sharply,which will cause additional temperature stress.If the additional stress and the residual stress of the component itself exceed the strength,it will cause the component to crack.
