The high intensity bus duct easy to disassemble, which is characterized in that the technique includes following steps：
（One）Coremaking：Sand core is produced according to plate face shape using resin sand；Then it is applied in sand core surface brush special-purpose fire-resistant obtained
Expect and lights processing；Sand core is finally sent into drying box, 350-450 DEG C of solidification temperature；
（Two）Molding：It will mold and be placed on pedestal before and after a pair of of metal outer mold first, so that the sprue in metal outer mold
Bottom is corresponding with cast gate on pedestal, and sprue, cross gate and Inner cast gate are provided in the metal outer mold；Then sand core is placed on
In metal outer mold, the sand core and metal outer mold cooperatively form four casting mold type chambers being axially sequentially distributed along sand core lateral wall, most
After close die cap；
（Three）Casting：By step（Two）Mold after middle molding, which is placed on cast-iron pot smelting furnace, carries out low-pressure casting, casting temperature
Degree：Between 700-750 DEG C, filling velocity：10-15cm/s, filling time：60-70s ；Boost pressure：1-1.2 kPa, pressure maintaining
Pressure：0.6-0.9kPa, dwell time：900-950s ；It must slowly be carried out when release, be sure not to be unable to fast pressure relief；
（Four）It unpacks and clears up：It unpacks after natural cooling 2 hours, successively opens die cap, metal outer mold when unpacking, then smash sand
Core takes out plate face blank and clears up the edge grinding at molding；
（Five）Cut off cast gate：Rack work cuts off the waste material at the cast gate of plate face blank.
8. the casting technique of high intensity bus duct easy to disassemble according to claim 7, it is characterised in that：The resin sand
Granularity be 3-4 sieve, dioxide-containing silica >=96% in resin sand, clay content < 1%, moisture < 3%.
9. the casting technique of high intensity bus duct easy to disassemble according to claim 7, it is characterised in that：In step（Three）
Metallic solution sequentially adds pretreating agent and the static 30- of nodulizer based on barium, supplemented by lanthanum into mold before being poured
Perlite slag making is dispensed on the surface of metallic solution to purify metallic solution and skim at once again after 35min.
