Basic parameters of full hard screw barre
Processing requirements of barrel screw Barrel screw processing technology requirements: (1) Technical requirements for barrel quality: ①The barrel is made of corrosion-resistant and wear-resistant alloy steel. At present, 38CrMoAl, 400 or 45# steel is mostly used in China. ② The cylinder blank should be forged to shape. ③The barrel should be tempered after rough machining, har
Design requirements of double alloy screw barrel The bimetallic screw barrel bimetallic process is a more commonly used process combination product with excellent corrosion resistance and wear resistance in recent years. It adopts HVOF high-speed spraying equipment to melt spray spray the surface of the screw to obtain a densely structured bimetallic screw. ; The bimetallic barrel adopts the me
Parallel double barrel screw specifications Parallel twin screw barrel specifications: ø45/2~ø200/2 Screw structure and compression ratio can be designed according to different products and different accessories. Parallel twin barrel screw technical parameters: quenched and tempered hardness: hb280-320 Straightness of screw: 0.015mm Nitride hardness: hv950-1100 After nitri
Damage reason and repair method of screw barrel of granulator: 1. The twisted screw should be considered according to the actual inner diameter of the barrel, and manufactured according to the outer diameter deviation of the new screw given by the normal clearance with the barrel. 2. After the thread surface of the abrasion screw diameter is reduced, the wear-resistant alloy is thermally
