Platform/rail ground rail Are used to assemble, test, welding and inspection platform stitching of large equipment, rail platforms using sensitive facilities, can be adjusted according to the equipment's support, more conducive to the operation of equipment. Grand met volume machinery and equipment can piece together or more rail, as a hosted application platform. Rails are indispensable in industrial equipment.

One Platform/rail ground rail Product name: rail, rail platform, bar terrace, t-slot rail, beam, iron geosyncline, basic channel iron, t-slot platform, dual-slot rail, rail platform, cast iron axle, Channel iron, cast beam platform.

Two Platform/rail ground rail Main use: to design according to a fixed point, spliced into a cast beam platform is mainly used for large equipment Assembly, testing, welding and inspection. Can be used instead of cast iron base platforms.

Three Platform/rail ground rail The advantages of using cast iron Rails, without large terrace, that is, material cost savings, and can take up very little space, very high cost performance.

Four Platform/rail ground rail Material: high quality HT200-250 of high strength gray iron, ductile iron axle QT400-18, QT400-15, QT450-10, QT500-7, QT600-3, QT700-2, QT800-2, QT900-2, such as material,

Nodular cast iron plate relative to the platform of grey cast iron, high wear resistance, ductile iron processing of table finish, roughness better than cast iron platform, tensile strength of advantage. Cast iron table surface hardness of HB170-240 casting artificial annealing after two 600-700 c or natural aging 2-3, completely remove internal stress, accuracy and stability, good resistance to abrasion

Process of ensuring the rail precision constant-stress relief annealing (generally used in welding under phase transition of the Organization, in order to prevent internal stress caused deformation and cracking process, generally lower temperatures) to stress tempering process:

Platform/rail ground rail Materials aging treatment:

Using stress relief annealing (also known as: Aging and tempering) or vibratory stress relief have reached remove internal stress effects.

Tempering temperature 530 ° c, thermostat 2-3 hours, 48 hours or more, the temperature dropped below 200 ℃, make natural cooling, transferred to the next procedure. Machining, lapping and a final inspection after passing the factory.

Platform/rail ground rail Material stress relief annealing (also known as: Aging and tempering) steps:

1, charging: charging temperature should not be too high, generally less than 150 ℃. Should ensure the heating process furnace gas charge cycle flow.

2, heating: the heating rate should be controlled at less than 60 ° c/h.

3, insulation: insulation temperature 540-560 ℃, maintained 4H.

4, the temperature: the temperature after the cooling; the cooling speed of less than 30 ° c/h.

5, the oven: oven temperature should be less than 200 ° c, should be less than 150 deg c in the winter.

HT250 material cast iron Rails ingredients: strictly according to the standard gray cast iron: ISO185-1988 implemented. Use lower-22# quality in Benxi iron and steel materials and various trace elements: 60% 22# in Benxi iron and steel scrap 25; 30%, allowance ar 60# 2% 75# Silicon 1% gave birth to before the furnace ferromanganese Silicon 75# 0.3% mobile. Hot metal temperature of 1400 ° c above (measured by thermocouple thermometer), take a small amount of liquid iron casting triangular test piece, after passing the review specimen, casting temperature 1300 c above, casting more than 24 hours after box, sand

Rail platform/rail specifications : Detailed drawings or specifications may be based on the demand side on both sides to agree on production processing.
