Description

КГШП-2500 т. После штамповки издели  нагревают до 1000°С в течение 15-20 минут и производ т рихтовку штамповок на том же прессе. Дополнительной технологической смазки при штамповке и рихтовке не требуетс .KGSP-2500 t. After stamping, the product is heated to 1000 ° C for 15-20 minutes and the stamping is straightened on the same press. No additional process lubrication is required for punching and straightening.

Поверхность заготовок и штамповок покрыта равномерным слоем покрыти , которое работает как смазка при деформировании, снижа  усили  деформировани  на 15-20%, улучша  формообразование и предохран   металл от окислени .The surface of the workpieces and forgings is coated with a uniform coating layer that acts as a lubricant during deformation, reducing the deformation forces by 15-20%, improving the shaping and preventing the metal from oxidation.

Разм гченное стекловидное покрытие в процессе двухкратного нагрева и деформации (штамповки и рихтовки) не скатываетс , аThe softened vitreous coating in the process of double heating and deformation (stamping and leveling) does not roll, but

равномерно распредел етс  по поверхности и хорошо удерживаетс  на металле.evenly distributed over the surface and well retained on the metal.
