Chughun in chushka is divided into pre-divided and foundry Pig iron can be further remelted into steel or other alloys for the production of various materials. This type of cast iron is produced for the following technological needs:
for further production of P1 and P2 alloys,(//tractor-service.com)
phosphoric grades PF1, PF2, PFZ,
brands of high-quality alloys PVC1, PVC2 and PVCZ,
for foundry production of PL1 and PL2 brands.
Depending on the mass fraction of silicon and the purpose, the following is produced: pig iron for steelmaking (P1 and P2); pig iron for foundry production (PL1 and PL2); red phosphorous cast iron (PF1, PF2, PF3); high-quality cast iron (PVK1, PVK2, PVK3). Cast iron is produced in lumps without crimps, with one or two crimps. The thickness of the shell in the place of compression should not be more than 50 mm. The mass of the chushka should not be more than 18, 30, 45, 55 kg. The quantity of cast iron ingots should be no more than 2% of the mass of the lot. The fight includes pieces of no more than 2 kg.
